Key Insights
Interest Share
Interest accounts for 43% of this loan's total repayments.
Loan Tenure
A longer tenure reduces EMI but increases total interest.
Prepayment
Even small prepayments can save you a significant amount.
Method and scope
Fixed-rate, fully amortising loan with equal monthly payments beginning one month after borrowing. The nominal annual interest rate is divided by 12. At zero interest, principal is divided equally across payments. Fees, insurance, property taxes, rate resets and prepayments are excluded. This is a principal-and-interest illustration, not a lender quotation.
Using this calculator in United Kingdom
UK mortgages often have an introductory fixed period followed by a different rate. This illustration holds your entered rate constant for the whole term. Stamp duty, conveyancing, mortgage fees and insurance are outside the repayment shown.
Try the starting example
Amount borrowed: £250,000; Annual interest rate (nominal): 5%; Loan term (years): 25.
Monthly principal + interest: £1,461.48.
Compare one assumption at a time
A longer term can lower the monthly payment while increasing total interest. Compare the repayment schedule and total interest as well as the first result. Keep the amount and rate fixed when reproducing this comparison; the illustration does not include a future rate reset. These fictional scenarios use the starting inputs printed above, not your current entries in the interactive calculator.

Are you comparing money available now with money set aside for retirement?
A cash savings goal and a SIPP balance answer different questions. The SIPP model includes basic-rate relief under its stated assumptions, while the savings tool excludes tax and account restrictions. Keep accessible savings separate from a retirement balance when comparing the results.
To reproduce the table, reset the calculator, change only the named input and compare the result and any warning. Record the assumptions with your result. See worked planning examples and our calculation and correction process.
