Loan Calculator — frequently asked questions
How is a loan payment calculated?
With the amortization formula: payment = P·r ÷ (1 − (1+r)⁻ⁿ), where P is the principal, r the monthly rate and n the number of months.
What's APR?
APR is the yearly interest rate. We divide it by 12 for the monthly rate used in the calculation.
Does paying extra help?
Yes — extra payments reduce the principal, which cuts the total interest and shortens the loan, though this tool shows the standard schedule.
Is it free?
Yes, free with no account.
