How it works

Enter the loan amount, interest rate and term to see the monthly repayment, the total interest over the life of the loan, and a year-by-year amortisation schedule. Every input is labelled with its unit — no guessing which box wants a percentage.

Common questions

Does this include fees or insurance?

No. It calculates principal and interest only. Add arrangement fees, insurance and ground rent separately.

What does the amortisation schedule show?

How each payment splits between interest and capital over time — early payments are mostly interest.

Is it accurate?

The maths is standard amortisation. Your lender may round differently or apply interest daily rather than monthly.
