How big is your gap?

This might sound like a personal question but it’s the most important thing to focus on when it comes to getting on top of your money.

Your gap is the difference between what you earn and what you spend.

The only way to make progress with your money and start to build wealth is to have a positive gap between what you earn and what you spend.

Positive gap = Power

Negative or Zero gap = Poverty

This page is all about working out the size of your gap each month.

You just need 2 numbers:

  • how much you earned that month
  • how much you spent that month

Let’s look at each of these numbers…

Gathering your numbers

How much you earned

This one should be relatively straightforward. If you’re an employee, look at your payslip. If you’re self-employed, you might need to do a bit of adding up of your invoices or checking what came into your bank account during the month.

No matter whether you’re employed or self-employed, we’re interested in the after tax number.

How much you spent

This one is potentially a bit trickier. There are a few different ways you can track your spending. It doesn’t matter how you do it just as long as you do it!

Here’s some guidance to help you…

Over to you!

Now that you have the two numbers, you can work out your gap. You’re ready! YAY!

Remember, your gap is the difference between what you earned and what you spent

So you need to do how much you earned minus how much you spent


  • You earned 3,000 and spent 2,500. You have a positive gap of 500 (3,000 minus 2,500)
  • You earned 4,000 and spent 5,000. Your gap is -1,000. You have a negative gap! (4,000 minus 5,000)
