A rough guide only. Lenders assess affordability differently and some will lend more, or less, than the standard income multiple. Half of any bonus is counted here.

A payment break is not automatic and interest keeps building while payments are paused. Speak to your lender first, and to us before you commit.

A word of caution

Useful for a rough steer, not a decision

Calculators use averages and assumptions. Lenders use criteria, credit files and stress tests, and they do not all agree with each other. Two lenders can differ by tens of thousands of pounds on the same application.

Affordability varies wildly

Income multiples are only the starting point. Childcare, credit commitments and the type of income you earn all move the number.

Rates move constantly

The figures here use whatever rate you type in. Ask us what is actually available for your loan to value today.

Stamp duty has exceptions

Reliefs, replacements of a main residence and mixed-use treatment can all change the bill. Your conveyancer confirms the final figure.
