Quick answer
A mortgage payment is mainly driven by four figures: the amount you borrow, the interest rate, the term, and whether the mortgage is repayment or interest-only. Lower rates, larger deposits, and longer terms reduce the monthly payment, but a longer term also increases total interest paid.
What This Calculator Helps You Test
This tool is useful for comparing deposits, testing how a rate rise affects monthly cost, and seeing how much extra interest a longer term can create. It is best used as a budgeting aid before you request a Decision in Principle or speak to an adviser.
What It Does Not Replace
A payment calculator does not tell you whether a lender will approve you. Mortgage lenders also assess income, committed outgoings, credit history, employment type, and stress-tested affordability before deciding how much they are prepared to lend.
