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
Both borrowing calculators let you include fees paid upfront or financed. The mortgage tool offers interest-only estimates with final capital shown separately. The loan tool models regular and one-off overpayments that shorten the term. Neither includes early-repayment charges or rate changes. The rate input is a nominal annual interest rate, not an APR or APRC comparison.
