❓ FAQ
What is the loan payment formula?+
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P = principal, r = monthly interest rate (annual rate ÷ 12), n = number of months.
What is an amortisation schedule?+
An amortisation schedule shows each monthly payment broken down into principal (reducing the loan balance) and interest (cost of borrowing). Early payments are mostly interest; later payments are mostly principal.
How does interest rate affect my repayments?+
A higher interest rate means more of each payment goes to interest and less to principal. On a $10,000 loan over 5 years: at 5% APR the monthly payment is ~$189; at 10% APR it is ~$212.
What is APR vs interest rate?+
Interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus fees and other charges, giving the true cost of the loan. This calculator uses the interest rate — check your loan terms for APR.
What is the difference between a fixed and variable rate loan?+
A fixed rate stays the same for the life of the loan — payments are predictable. A variable rate changes with market conditions — payments may rise or fall. This calculator assumes a fixed rate.
