What is a payment?

Use this payment calculator to estimate a regular installment for a fixed-rate balance. It can help compare different repayment terms, understand the effect of interest and estimate the total amount repaid. It does not include lender fees or penalties.

Formula and calculation method

Payment = P × r ÷ (1 − (1 + r)^−n). At zero interest, payment = P ÷ n.
