How it’s calculated

Uses the standard amortisation formula for a fixed-rate loan with equal monthly payments. Fees and variable rates are not included.

payment = P × r ÷ (1 − (1 + r)^−n) r = annual rate ÷ 12, n = months

Worked example

Borrowing $25,000 over 5 years at 8.5% costs $512.91 a month, and $5,774.80 in interest over the whole loan.

Questions

Is the annual rate the same as APR?

Not always. APR includes some fees. Enter the nominal interest rate for the payment and compare APRs between lenders separately.

Does a shorter term save money?

Yes. Monthly payments go up, but you pay interest for fewer months, so the total interest falls.

Doing these numbers every month? Accounting software can automate invoices, reminders and tax reports.
