Buy-to-let mortgage calculator
Estimate monthly payments for a repayment or interest-only mortgage. Across all four UK nations this projection uses the nominal annual rate divided by twelve for the full term. The fixed payment model rounds monthly interest and repayments to pennies and adjusts the last repayment to clear the balance. Interest-only capital falls due at maturity. Insurance and upfront fees are entered separately. Excludes rate changes and daily interest.
Worked example
Borrowing £180,000 at 4% interest-only costs £600 a month. After 25 years the £180,000 capital still needs repaying.
At zero interest a repayment mortgage spreads the capital evenly across the term. With interest-only borrowing the full capital remains due. MoneyHelper repayment options
Select the full monthly schedule to see principal, interest, insurance and the remaining balance. The final interest-only instalment includes the capital repayment. Upfront fees enter the total cost once.
