About Loan calculator

The Loan Calculator computes monthly repayments, total interest paid over the full loan term, and a complete amortisation schedule showing how each payment is divided between principal reduction and interest. It uses the standard annuity formula and works for any combination of loan amount, annual interest rate, and term. Useful for comparing mortgage offers side-by-side, understanding the true cost of a car finance agreement, evaluating personal loan options, and seeing how overpayments would reduce the total interest paid.
