Mortgage calculators
If you're looking to find out how much you can borrow or what your mortgage repayments might be, you've come to the right place.
Banks will often let you borrow more money than you can actually afford. We’ll help to give you an idea of how much you can afford to borrow.
And if you are looking to work out what your repayments might be, check out our mortgage repayments calculator.

Wondering about your deposit?
Basically, banks won't lend the full amount for a house - you need to be able to put down a deposit, and the more the better. You may be familiar with 20% as the magic number, but the reality is if you're in a strong financial position we can work with as little as 5% deposit.
