Loan & Interest Calculators
Work out monthly payments, total interest and full repayment schedules before you borrow.
How is a loan payment calculated?
A loan payment is worked out from the principal, the monthly interest rate and the term using the equal-instalment (amortization) formula: you pay the same amount every month, but the interest share falls and the principal share grows over time.
The loan calculator shows the monthly payment, the total interest and a month-by-month amortization schedule, so you can compare terms before you borrow.
How do savings and interest grow?
Savings grow through compound interest: interest earned each period is added to the balance and earns interest itself, so growth speeds up over time.
The savings and compound interest calculators in the investment section show how regular deposits and the interest rate add up year by year.

Frequently Asked Questions
Why might a bank’s quote differ from the calculator?
Banks may add arrangement fees, insurance or other charges. Compare offers using the annual percentage rate (APR), which includes those costs.
Can I see the repayment schedule?
Yes. Use “Show table” on the loan calculator to see each month’s payment, interest and remaining balance.
