UK Mortgage Calculator

Coming soon · #19

Monthly repayments and how much you can borrow — capital & interest or interest-only.

About this tool

Planned: a UK mortgage calculator with repayment and interest-only modes, affordability estimates (around 4.5× income is the common lender benchmark) and overpayment links. Best launched as a property cluster with the stamp duty calculator rather than alone, and strictly as a calculator — no advice, per FCA rules.

Frequently asked questions

How much can I borrow for a mortgage?

UK lenders commonly lend around 4 to 4.5 times your income, sometimes more for high earners, subject to affordability checks on your spending and debts.

What does a mortgage calculator not tell you?

Whether a lender will accept you — calculators use maths, not credit checks. They estimate payments and borrowing ranges only.
