💸 It’s Only 1%… Right?! 🤯
How much damage can a teeny-tiny 1% fee really do to your investments? Spoiler alert: A LOT. Like, life-changing amounts. 😱
For years, people told us “fees matter,” but we wanted to see it. Feel it. Understand it in our bones (and our bank accounts). So when we stumbled across some dusty old paperwork from one of Katie’s first-ever investments while clearing out our flat, we got curious. 🕵️♀️
That first investment? Oh, it was with a very shiny, very expensive London investment firm. Think suits, skyscrapers, and sky-high fees. Later, we switched to a low-cost Vanguard Index Fund and… WOW. The difference was jaw-dropping. Like, “why didn’t anyone teach us this in school?!” kind of shocking. 😤
We wrote a whole article about it (because of course we did): Impact of Fees. 📚
Then, during one of our Rebel Finance School sessions, we got really fired up about fees. Katie got so excited she disappeared for two days and came back with a shiny new tool 🛠️ that shows you exactly how much fees are costing you over time. It’s simple, powerful, and might just blow your mind. 💥
Rebel Ninja Martin has now taken the tool Katie created and built it into this web page for you to use. You can compare the difference in fees over time between any two investments!
🛠️ How to Use the Fee-Slaying Tool of Awesomeness 💥
Ready to see how much your investments are being mugged by fees? Let’s go! 🕶️💼
This magical little tool lets you compare two investment funds or platforms side-by-side. On the left, you pop in your current fund or the one you’re eyeing up. On the right, we’ve pre-loaded the legendary 🏆 Vanguard FTSE Global All Cap Fund — one of our low-cost heroes.
Once you’ve entered your numbers, the tool does its thing and calculates the impact of fees over 30 years (yep, thirty 😲). You can tweak the growth rate if you’re feeling fancy or want to match your own assumptions. 📈
🎮 Have a play! Then either:

🎛️ Tool Time: How to Use the Fee Comparison Wizard 🧙♂️💰
Alright, Rebels — here’s where the magic happens. This tool is your financial X-ray machine 🔍 for spotting sneaky fees that are quietly nibbling away at your future wealth like little investment termites. 🐜💸
🟦 Fund 1 (Left Side, Blue):
This is where you plug in your current fund or the one you’re thinking about investing in. Got a flashy advisor with a shiny brochure and a 7% fee? Pop it in here.
🟩 Fund 2 (Right Side, Green):
We’ve pre-loaded this with the Vanguard FTSE Global All Cap Fund — our low-cost, globally diversified, no-nonsense investing hero. 🦸♀️🌍
Once you’ve entered your numbers, the tool crunches the data faster than Alan can say “compound interest” and shows you the difference over 30 years. 📊
🧩 What You Can Tweak:
- Initial investment – Got a lump sum ready to go? Stick it in here. This might be how much you already have or the amount you are going to start investing from now.
- Monthly investment – How much are you investing each month? If you invest yearly, divide by 12 and pop that in.
- Annual growth rate (%) – What is the average yearly return you expect? The financial industry often uses 7% as a long‑term estimate for broad-based global index funds. Our own portfolio has averaged over 13% over the years. We set the default at 10% as a realistic middle ground. You can adjust this number to match your own expectations or comfort level.
- Fund name – Give your fund a name so you know what you’re comparing. If you don’t, it’ll just say “Fund 1” and “Fund 2” like a boring spreadsheet.
- Initial fee (lump sum) – Some advisors charge a % just to start. We’ve seen this as high as 7% 😱. Enter the % or £ amount and select the right one from the dropdown.
- Initial fee (monthly) – Same as above, but for your monthly contributions. Vanguard? That’s a big fat 0%.
- Ongoing Charges Fee (OCF) – This is the annual % fee for running the fund. Vanguard FTSE Global All Cap is 0.23% in the UK.
- Advisor fee – If your advisor charges you a % or flat fee for their wisdom, enter it here.
- Annual platform fee – What the platform charges you to hold your investments. Vanguard UK is 0.15% with a cap (most investment advisors don’t cap their fees, why would they? It is not in their best interests! But some of the good guys do so you don’t end up overpaying!).
- Minimum platform fee? – Some platforms say “you’ll pay at least £X per year.” If so, tick “Yes” and enter the amount. Vanguard has a £4 a month minimum in the UK.
- Platform fee cap? – Some platforms say “you’ll never pay more than £X.” Tick “Yes” and enter the cap.
- Exit fee – Planning to leave your fund one day? Some providers charge you to break up with them 💔. Enter the % or £ amount here. One of our least favourite firms in the world SJP are famous for high exit fees which still exist even though the regulator told them off!
🧪 Want to Try a Real-Life Example?
Here’s what Katie’s old fund looked like (aka: the expensive mistake that inspired this whole thing):
- Fund name: Penny Group
- Initial & monthly fees: 3% 😬
- OCF: 1.61%
- Platform fee: 0.60% (no cap)
- Exit fee: £0 (finally, something nice)
🕰️ Why 30 Years? Because You’re Not Just Investing Until You Retire… 💀
You might be thinking, “30 years?! I don’t have that long!” But hold up — let’s talk about your real investing timeline.
Most people think their investment horizon ends the day they retire. Nope. Wrong. 🚫 Your investing timeline isn’t until you retire — it’s until you expire. 💀💸
If you’re 60 now, you might live another 30 years (or more!). That means your money needs to keep working long after you’ve stopped. Whether you’re drawing down your pension, living off dividends, or just trying to outlive your cat 🐱 — your investments are still in the game.
And here’s the kicker: fees compound just like your returns do. Over 30 years, even a 1% difference in fees can cost you tens of thousands. That’s the difference between sipping cocktails on a beach 🏖️ or sipping lukewarm tea in a drafty flat. ☕️🧣
So yes, we use 30 years because that’s when the difference becomes crystal clear. It’s not about being young — it’s about being smart. 🧠💪
🎯 What This Tool Actually Does (and Doesn’t Do) 🧠
Let’s get one thing straight: this tool has one job — to show you the impact of fees on your investments over time. That’s it. No more, no less. 🧮💥
It won’t tell you which fund will perform better. It won’t predict the next stock market crash. And it definitely won’t make you a cup of tea. ☕ (Martin is working on that last one.)
Why? Because we wanted to laser-focus on just one thing: how much fees are quietly robbing you of your future wealth. Once you understand that, you’ll never look at a 1% fee the same way again. 😤
We’re building other tools to tackle things like fund performance, retirement planning, and tax — but for now, this one’s all about the fee monster. 🐉
🧮 Assumptions Behind the Scenes
- 10% Growth Rate 📈
The tool assumes a nice, steady 10% annual return. Real life? Not so smooth. Markets go up, down, sideways, and occasionally do backflips. But this gives you a solid baseline — and yes, you can change it if you want to get fancy. - No Tax 🙈
We’ve kept it simple and assumed you get to keep all your gains. In reality, tax might nibble away at your returns — unless you’re investing through tax-efficient accounts like a pension, SIPP, or ISA in the UK. (And if you’re not… why not?!)

👇 Keep scrolling to find out why fees are THE #1 predictor of how well your investments will do (and why we won’t shut up about them). 🎯

⚔️ The Difference: Fees vs. Performance — Who Wins the Wealth War? 💸🏁
Can you really judge a fund by its fees alone? 🤔 Are fees really the biggest factor in how well your investments do?
Short answer: YES. Long answer: YEEEESSSSSS. 📣
At Rebel Finance School, we bang on about fees like a broken drum 🥁 — and for good reason. The tool above shows you just how brutal a 1% fee can be over time. It’s not just a rounding error — it’s a retirement-wrecker. 😱
But let’s break it down. There are two big players in the investment game:
- 💰 Fees – This is what you pay to play. Some funds (like American Vanguard ones) charge as little as 0.04%. Others? We’ve seen eye-watering fees of 7% from slick-talking advisors in shiny suits. That’s not investing — that’s daylight robbery.
- 📈 Performance – This is how well your fund actually does. Do the stocks go up? Do you get dividends? Does your money grow like a well-fed houseplant? 🌿
Now here’s the kicker: you can’t control performance. The market does what it wants. But you can control fees — and that’s why they matter so much. Every pound you don’t pay in fees is a pound that stays in your investment, compounding away like a little financial snowball. ❄️➡️⛄
So yes, fees aren’t the only thing — but they’re the first thing you should look at. Because if you’re paying 2% in fees and getting 1% in returns… well, you’re not investing. You’re donating. 😬
🧠 The Truth About Fees vs. Performance: The Dream vs. Reality 💸✨
The tool above focuses purely on fees — but that’s just one part of the investing puzzle. For Katie’s first flashy advisor, not only were the fees sky-high, but the performance was… well, let’s just say underwhelming. 😬
Here’s the dream they sell you:
💼 “Sure, our fees are higher — but that’s because we’re better. We’ll outperform the market and make you more money than those boring index funds ever could.”
Sounds tempting, right? Like paying extra for the Rolls Royce of investing. 🚗💨 But here’s the reality: that dream? It’s upside-down. In fact, the data shows the opposite is true.
📚 What the Research Says (a.k.a. Alan Gets Geeky)
After reading Trillions (a brilliant book about the rise of index funds), I dove into the research. One study in particular — “Shopping for Alpha: You Get What You Don’t Pay For” — blew my mind. 🤯
Vanguard looked at a bunch of factors to see what actually predicts fund performance:
- Expense Ratio – How much the fund charges you
- Fund Concentration – How diversified it is (e.g. number of stocks)
- Turnover – How often the fund buys and sells investments
- Fund Size – Total assets under management
- Past Alpha – How much the fund beat the market in the past
And the winner was… 🥁
“The expense ratio separated poorly performing funds from better performing funds more successfully than all other metrics we analyzed.”
Translation? The cheaper the fund, the better it performed — on average.
And combining other metrics didn’t help. The expense ratio alone was the most powerful predictor of future performance. 🎯
🤔 “But Don’t You Get What You Pay For?”
Not in investing. In fact, it’s the opposite.
“On average, lower-cost funds tend to produce better future results than higher-cost funds.”
— Wallick, Wimmer, and Martielli (2013); Philips et al. (2014)
Crazy, right? The less you pay, the more you keep — and the better your returns tend to be. Why? Because low-cost funds are usually passive (like index funds), and high-cost ones are usually active (with managers trying to beat the market). And historically, passive funds have outperformed active ones in most cases. 📉➡️📈
So if you’re looking for one simple predictor of long-term success?
👉 It’s fees. The lower, the better.
High fees don’t just cost you more — they often come with worse performance too. That’s a double whammy. 💥💥
You may have seen a recent open letter I wrote to Wealthify which was entitled Wealthify or Poorify. Wealthify have high fees and poor performance. They promise the dream of investing with us will create better returns, but they have FAILED to do this over the long term.
If you want to have a read of the overview from Vanguard, you can see if here and then dig down further if you want to. The impact of investment costs | Vanguard
🧭 What You Can Control — And Why It Matters 💪
Let’s be real: there’s a lot in investing you can’t control.
You can’t stop recessions. You can’t predict pandemics. And unless you’re secretly running a country, you probably can’t prevent geopolitical chaos either. 🌍💥
But here’s the good news: fees? You can control those.
And doing so might just be the single most powerful move you make as an investor. 🎯
If You’re in the UK or US…
You’ve got it easy. Just invest directly through Vanguard and you’ll be slashing fees like a financial ninja. 🥷💸
If you’re elsewhere in the world, you can still access Vanguard funds — you might just need to go through a different platform. But the principle is the same: low fees = more money for you.
You can find our Full Platform Review for the UK here.
📝 Your Rebel Homework
Time to take action. For every investment account you have — pensions, ISAs, 401(k)s, SIPPs, Roths, and beyond — find out:
- 💼 What are you actually invested in?
- 🔍 What are the underlying funds?
- 💸 What are the fees? (Platform, OCF, entry/exit, advisor fees — the whole lot!)
- 🏢 What kind of pension do you have?
- Is it defined benefit or defined contribution?
- Does your employer match contributions?
The more you know, the more power you have. Knowledge = control. Control = freedom. 🚀
So go forth, Rebels. Take back control of your money. Slash those fees. And don’t leave your financial future in the hands of people who profit whether you win or lose. 💥

PS Martin Rebel Ninja we could not have done this without you. You are amazing.

Hi Katie&Alan, thank you for this great update on the tool! I’m a big fan of Vanguard and have been taken aback by the fees news and been thinking about what to do so it’s phenomenal you’ve turned this into a collective effort!
I’m not sure whether I’m using the tool correctly as whatever amount of investment I add the result is always the same (-5,681), I did double check I’m following the instructions re all the quirks? Thank you!
hey Elisa. Thank you for the lovely comment. We wanted to make it super clear how much (or not!) the Vanguard fee change might impact people over the years.
Hmmm that’s strange about the tool telling you it’s -5,681. It seems to be working correctly for me. One thought is the tool might not be recognising your inputs as numbers. Please can you have another go and see what happens? If it still happens, please can you send a screenshot to hello@rebeldonegans.com and I will investigate!
You are lovely Elisa. Thank you for taking the time to comment!
Katie
Hi Katie and Alan, I hope you are both well, and thank you for this amazing course! I’m trying to compare AJ Bell Vs Vanguard SIPP fees, and would be grateful for your help. For the foreseeable future I anticipate making 1 lump sum payment into my account each tax year. My questions are 1) how do I/can I model this in your fees calculator, to take account of AJ Bell’s transaction fees? (ie you advise to divide future lump sum payments by 12, but AJ Bell charge £1.50 per deal – how does this affect the results? 2) 2) Your calculator is based on the cost after 30 years – I won’t be investing for that length of time. Are you able to allow the results graph to become expandable, so I am able to see at what point (if this happens,) the fees become cheaper with one provider as opposed to the other. I hope this all makes sense! Many thanks
I can’t make the tool work. It does not allow for a download or for numbers to be entered directly above. Is there is a link to the tool that I can use?
There is a link below it that you can download the spreadsheet. Are you able to do that? Are you on your phone or laptop?
hi there – thanks for providing so much useful information. I’m new to your site (literally two days) but love it. Can’t wait for the school to start in June. I can’t get the tool above to work nor find a link. I’ve tried on iPhone and apple laptop on edge, chrome and safari. Please could you post a link? many thanks Julian
Julian, We have just found out Microsoft has changed how their embedding spreadsheet works. it is so annoying. We are working to find a new solution and will have it up again soon! Sorry. I am so sorry. Will have it ready again soon
It would seem that Microsoft has changed/broken the embedding spreadsheet function (again), we’re looking at alternative methods of doing this
Thanks for replying Martin. We need to come up with a new way of fixing this!
I’ve added a direct download link for the spreadsheet and this will get a revamp in time for the investing part of the course this year
Hi Alan and Katie, I am also trying to use the tool but it’s not working. Is there another way we can access it yet?
Regards
Trudy
Trudy, it is super annoying. Microsoft changed something and broke it all last week. We are working on a solution now. Sorry about this. Alan. PS Emailed you separately with a solution
hi Alan, I’m new on this. I’m also unable to open :(
hey Maria, it is down at the moment. Microsoft changed something and screwed it up so we are working to find a new plan. Sorry about this. We will work to get it going again! Alan
I’ve added a direct download link for the spreadsheet and this will get a revamp in time for the investing part of the course this year
Can you point out where I can find the link? I’m a spreadsheet geek and I want to do the data entry for the various funds I have – and keep a saved version. :-)
My thinking is to move large sums from vanguard to iweb, that has zero ocf, or am I missing something?
Hey Peter, Are you in the UK? The OCF is on the fund and no matter where you invest their will be an OCF Fee.
Thanks Alan, I realise I mean the platform fee is zero for Iweb. I am uk based. I have since read your comments on Halifax, which is the same underlying platform. My experience is they have been fine. Thanks so much for your informative course!
Absolutely loving this and have just shared with my brother to do as he has his pension with SJP and my word alone is not sufficient for him to doubt them! I am looking at a fund fact sheet (for Fidelity Index World Fund P accumulation) that includes a Transaction Cost of 0.01%. I am not sure where to include that? (Its for my kids pension, I chose fidelity cos they don’t charge a service fee for junior products, I didn’t realise there were lots of other fees!) Thanks so much!!
Gemma what a lovely post. Thanks for replying. I would just add the 0.01% to the OCF figure in there and it will work it all out for you. That seems like a great choice. What are the OCF charges. And for your brother I thought he might be interested in the experience of Mark who has become one of the Rebel Ninjas: https://rebeldonegans.com/st-jamess-place-wealth-management-vs-global-index-funds/
Hi Alan, the OCF is 0.12 but then there is a negotiated fund manager discount of 0.02. So including that transaction cost I guess is 0.11 in total. So fee wise it sounds pretty good I think.
As for my brother, I sent him that link as soon as you shared it that week that Ninja Mark talked us through his story. He lives in France though now so I don’t know if that reduces his options to transfer? 🤔
Hey Gemma, 0.11% as an OCF is a good fee. Less that we pay for our fund so nice work! YAY.
For your brother it might limit his options but I am SURE there is a low fee option for him that we could find. I am positive.
Hi, is this comparison working today? I’ve put in the fees for my HL account but it shows no growth for fund 1 only for fund 2?
Hey Alison, it is working for me. Make sure you hit calculate every time you change a figure as it doesn’t auto update. You have to hit the button. Send us a screen shot if it still isn’t working as I seem to be getting it to work my end. Tell me more…… Alan
Great tool team. Does it make any difference that my regular additions (KiwiSaver, so taken automatically from my salary payments) are fortnightly rather than monthly? I’m assuming if I multiply the fortnightly amount by 26 and then divide by 12, that will give me a rough monthly amount. For a fund that charges a fee for each deposit, that should still give me an accurate fees number, right? Or am I missing something 🤔
Hey Helen, you are right, just multiply it so you get to monthly and then use that figure. That will work super well for you. You have got it right. Alan
This is a brilliant, useful, practical and FUN tool. I’m playing away to my heart’s content! Thank you so much, Katie. It would be useful if the tool could factor in regular drawdowns as well, for those of us who are getting close to that stage.
Hey Louise, that is a challenge modelling for all the different countries in a tool but we do have the Draw down session coming up in a couple of weeks on the course and then the forecasting spreadsheet where you can model that too! Sending you happiness
Alan
Thank you Katie & Alan for the tools and the wisdom you’ve shared on YouTube — you’ve officially converted me! I just wish I had discovered this 30+ years ago.
I lost my teenage life savings in a share market crash — not a huge amount in the grand scheme of things, but enough to put me off shares for decades.(But I did learn alot and that I don’t know everything ).
Thankfully, I did start investing 10%+ of my income from age 25 (I’m now 60, retired at 56), thanks to some good advice from investment books.
As a Kiwi, I naturally leaned into property investment(as we tend to do!). It worked out for me as I can do most things myself.
When I retired from a waged job, I sold a large home and used the proceeds to buy three properties — two are now rentals.(yes I know I’ve put them through the calculator). I’ve also have $200k in banks, $200k in the NZ sharemarket, $100k PTP and $600k with well-known NZ fund managers. Yes all over the place (shaking my head).
Sadly, those fund managers charged high fees and returned just 1.2% over the past four years. That was the last straw. This led me to finding your content, I’m now in the process of shifting to a Total World Fund. (knowing its til expirement) :-)
Thanks again — you’ve made a real difference to my thinking.
Peter, that is awesome you have started to figure all this stuff out about investing. Exactly the same happened to me losing my life savings in the dotcom bubble as a 20 something and then being put off investing for 13 years! LOVE that you are taking control and reducing fees and this is so exciting. We hope to meet you on the next tour of New Zealand! Katie and Alan
Thanks for the comparison tool, and all your educational guidance. Am I right in assuming the preset Vanguard FTSE Global All Cap Fund fees would be the same whether investing in the same fund (and platform) via SIPP, ISA or GIA? And is the behind the scenes spreadsheet available for download?
the fees for the fund are the same wherever you invest. But the platform fees and other fees might be quite different Rich. Does that help? Alan
Thanks for the additional pointers, Alan. I reviewed Week 7 index investing again and the fees section makes more sense on second viewing (and watching the spin-off how to evaluate a fund fact sheet session). I’ve now set my product comparison up in sections covering platform fees, dealing/entry fees, fund fees, exit fees, and IFA fees. This helps me to be certain I gather all facts before making decisions. Prior to this question I risked only part comparing product costs without knowing if all the component parts were captured.
Hi, I did the course last year. Thank you so much for introducing me to investing in my future. It has been a very positive year. My question is, would you transfer your investment to ii once the portfolio reached £130.000? Thank you in advanced
Hey Monica who are you with? It all depends on where you are and who you are with. If you are with Vanguard it isn’t going to make much difference at all over the long term and we would just stay there…. Sending happiness Alan
Excellent tool with its detailed components.
Would be great if you could add a return option as you might be trying to compare two different funds that have achieved different returns. Fir me I’m looking to take account of the returns as well as the fees.
Hello – please can somone help? I’ve just finished my first watch of the course and feel a little overwhelmed, but it’s starting to sink in. I am considering combining 2 pots to make a £125,000 and intend to use FAD to eventually withdraw all the money to bridge the gap – we will then downsize our house. Which platform would be best for this? with the lowest fees? Thank you in advance of anyone’s help.
Hey Janine, is this for a SIPP? ISA? General Account? Our platform review might help? https://rebeldonegans.com/blog/uk-investment-platform-review-2025/
Hi – would it be possible to make your tools downloadable so we can play with them a bit more?
Many thanks
I retired end of June aged 56 as I got the option for redundancy after 17 years. I don’t need to draw any pension income until late next year and then intend to crystallise below the 40% tax amount each year. I also have 2-3 years of cash funds available if needed and a BTL property which is mortgage free. I plan on consolidating my 3 pension pots and moving to a low cost platform and just need to make fund choice. Would it be crazy to go for a passive global index fund? I know people get cautious close to retirement but I have back up funds and won’t be taking my pension all at once so I’m OK with taking some risk for growth. Was specifically looking at Vanguard FTSE All World ETF which seems to have maximum diversification and low fees (following reading/watching your advice)
Wendy, we won’t think that is crazy at all. You have income from a rental property. 3 years buffer and you are set to weather any storms or sequence of returns risk. Did you watch week 10 of the course this year? do you know your safe withdrawal rate that you are going to use? We are retired and nearly all in global index funds. The one you listed is great. Does this help? Alan
Hi, what happens in the scenario that your fund outperforms the vanguard even after the fees are taken? Would compounding still be less with the fee paying fund and if so why?
Hey Jo, there are years where actively managed funds outperform the market average. normally this is only a year or two and no one does it over time. The time frame for the data is so important as the active funds love to show you 1-3 years of data to prove you should go with them.
For the compounding and fees you need to know if the returns they are showing you are pre or post fees. if they are post fees then that should be what you are actually receiving. Is this on a fund you are examining or from a manager you have? Can you tell us a bit more? Alan
