Repayment Calculator

Punch in your loan, term, and rate. See your monthly payment, total interest, and the capital-vs-interest split — without the spreadsheet.

How the numbers land.

Three steps from input to a figure you can plan around.

  1. Enter your figures

    Loan amount, mortgage term in years, and the interest rate from your offer (or a comparable best buy).

  2. Read the result

    Monthly repayment, total interest paid over the term, and how much of each payment goes on capital vs interest.

  3. Speak to a broker

    Take the figure to a CeMAP-qualified adviser who can match it to a lender that will actually approve the case.

What we assume.

Every calculator is a model. Here's where ours rounds, simplifies, or hands the detail to a real adviser.

  1. Capital repayment basis

    Standard UK capital-and-interest schedule. Interest-only and part-and-part loans aren't modelled here.

  2. Constant rate over the term

    The rate you enter is held flat for the full term. In reality you'll re-fix every 2–5 years; results show today's rate, not lifetime cost.

  3. No insurance or fees

    Buildings insurance, life cover, broker fees, arrangement fees, and valuation costs aren't included. Budget for those separately.

  4. No overpayments factored

    Any extra payments you'd make are excluded. For that, use the overpayment calculator.

Frequently asked.

It estimates your monthly mortgage payment for a chosen loan amount, term and rate, plus the total interest paid over the term. Use it before applying so you understand what each rate move costs you.
