Mortgage deposit calculator

Work out how much you need to save for your mortgage deposit and how long it will take you.

This calculator is for illustrative purposes only and does not take into account your individual circumstances.
Your home may be repossessed if you do not keep up repayments on your mortgage.

You’re ready to make your first move onto the housing ladder and you might even know the area you’d like to make your neighbourhood.

Perfect for first-time buyers, our mortgage deposit calculator can help you work out how much you need to save for a home typical for the area you’re looking in. Work out how long it will take you to save, depending on how much you’ve already got and what you can put away each month.


Start with the amount you expect to pay for your new home – for example £150,000. From there you can work out what your required deposit will be. For example:

Deposit Home price £150,000 Home price £225,000
5% £7,500 £11,250
10% £15,000 £22,500
20% £30,000 £45,000

Your mortgage deposit is the amount you pay upfront to buy your new home. The more deposit you put down, the smaller your overall mortgage will be. This could potentially mean you start off with smaller monthly payments or pay the outstanding mortgage off more quickly, by reducing the number of years you need to pay off your mortgage.
