Mortgage affordability calculator FAQs
We know getting a mortgage can seem pretty complicated, so we've listed the questions we hear all of the time.
How to calculate mortgage affordability
Most affordability calculators will multiply your income by 4 or 5. However, ours is a little more refined.
We take into account the number of applicants on the mortgage, alongside any dependents and credit commitments you may have, for a significantly more accurate result.
This provides a window of what your potential borrowing could be, up to the maximum borrowing amount.
How do lenders calculate affordability?
When offering a mortgage, lenders look at your monthly income, your monthly outgoings - and how much you can comfortably afford to repay. They'll check:
Your credit rating and any loans or credit balances
Any other large outgoings, including children and dependents
Your age and employment status
Your preferred mortgage term
How much can I afford to borrow for a mortgage?
Generally, banks and building societies will lend between 4 and 4.5 times your total household income.
The most important thing lenders look at when offering a mortgage is your monthly income.
The second most important thing is your monthly outgoings - and how much you can comfortably repay.
How does my down payment affect affordability?
The larger your down payment or deposit, the more favourably lenders will view your application.
A larger down payment also affects the mortgage interest rate you could pay, with the best rates reserved for those with larger deposits.
For example, a down payment of 10% of a property's total value will open up better interest rates than a down payment of 5%.
The best mortgage rates become available to you once your down payment reaches 40%.
Can I use this calculator if I have student loans or other debts?
This calculator doesn't take your monthly outgoings into account. It shows how much you could potentially borrow.
When you go through the process of arranging a Mortgage in Principle with us, which involves a soft credit check and doesn't commit you taking out a mortgage, we'll then start to look into your monthly outgoings too.
Once your income and monthly outgoings are taken into account, you'll have a more solid idea of how much you can borrow from a lender.
How is affordability for a mortgage calculated?
It's generally accepted that you shouldn't spend more than 28% of your monthly income on your mortgage and home insurance costs.
Overall, you shouldn't spend more than 36% of your monthly income on your general household costs, including:
mortgage payments
insurance
household bills
any debts.
