Understanding a repayment estimate
How the amount, interest rate and term affect the result.

The three inputs
Our loan and mortgage calculators use the amount borrowed, an annual interest rate and a repayment term. They assume the rate stays the same and that you make an equal payment every month.
Monthly payment and total cost
For a positive interest rate, spreading the same loan over more months reduces the monthly repayment but increases total interest. Look at both figures when comparing examples.
Fees and exclusions
The mortgage calculator lets you include fees paid upfront or added to the loan, and offers interest-only estimates with the final capital shown separately. The loan calculator excludes fees. Neither tool models early repayment charges or rate changes. The interest-rate field is a nominal annual rate, not an APR or APRC comparison.
