Mortgage affordability calculator
Use this calculator to estimate how much you could borrow and your potential property budget. It uses your income and deposit as a guide. Lenders will also consider your regular outgoings and personal circumstances.

Enter your annual income, then select Calculate borrowing to see your estimate.
Standard borrowing estimate
This indicative estimate is based on 4.5 times the gross annual household income entered. The amount you can actually borrow will depend on the lender's affordability and eligibility checks.
Potential enhanced borrowing
Some eligible first-time buyers may be able to borrow up to six times their gross annual income through selected mortgage products. This is not guaranteed and remains subject to the lender's full affordability, credit and eligibility checks.
Property budget (standard estimate)
Loan to value (LTV)
LTV shows the mortgage as a percentage of the estimated property budget.

Your questions answered
What does a mortgage affordability calculator show?
A mortgage affordability calculator gives you an indication of how much you could potentially borrow based on the income you enter.
Our calculator also combines your borrowing estimate with your deposit to show an estimated property budget and loan-to-value (LTV). These figures are only a guide and are not a mortgage offer or formal affordability assessment.
How does the calculator work out my borrowing estimate?
Your estimate depends on your income, whether you are applying alone or jointly, and whether all applicants are first-time buyers.
For most applicants, the standard estimate is based on 4.5 times your gross annual household income.
Some applicants may see a different estimate:
- Sole first-time buyers earning £30,000 or more may also see potential enhanced borrowing of up to 6 times their income.
- Joint first-time buyers with a combined income of £50,000 or more may also see potential enhanced borrowing of up to 6 times their combined income.
- Joint applicants who are not all first-time buyers and have a combined income of £100,000 or more may see a standard estimate based on 5.5 times their combined income.
These figures are indicative only. The amount you can actually borrow will depend on the lender’s affordability, credit and eligibility checks.
Why am I seeing a potential enhanced borrowing figure?
Some first-time buyers may potentially be able to borrow more through selected mortgage products.
The calculator shows an enhanced figure where all applicants are first-time buyers and either a sole applicant earns at least £30,000 a year, or joint applicants have a combined income of at least £50,000 a year.
The enhanced amount is shown separately from your standard borrowing estimate. It does not mean you will necessarily be able to borrow that amount, and any mortgage remains subject to the lender’s full affordability, credit and eligibility checks.
How do lenders work out mortgage affordability?
Mortgage lenders look at more than your income when deciding how much you could borrow.
They may also consider your regular expenditure, existing debts, credit history, deposit, employment circumstances, mortgage term and the property you want to buy.
Different lenders use different affordability and eligibility criteria, which means the amount you may be able to borrow can vary between lenders.
Does my deposit affect how much I can borrow?
In this calculator, your deposit does not change the income-based borrowing estimate. Instead, it is added to your estimated mortgage amount to show your estimated property budget.
Your deposit also affects the loan-to-value (LTV) shown by the calculator. In practice, lenders will consider your deposit alongside your income, expenditure and other circumstances when assessing a mortgage application.
Is an affordability calculator the same as an Agreement in Principle?
No. An affordability calculator gives you an indicative estimate based on the information you enter. It is not a mortgage offer or formal affordability assessment.
An Agreement in Principle is a separate step that gives you a more personalised indication of how much you may be able to borrow.
Your home may be repossessed if you do not keep up repayments on your mortgage.
