Loan Payment Calculator estimates the fixed monthly instalment on an amortising loan, together with the total repaid and the interest portion, from the amount borrowed, the annual rate and the term in years. It is aimed at anyone previewing car finance, a personal loan or a mortgage before speaking to a lender, and at borrowers who want to see how stretching the term lowers each payment while raising the lifetime interest. The standard amortising formula is used with a monthly rate, and a zero rate simply divides the amount evenly. Fees, insurance and taxes are excluded, so results are estimates rather than offers. All arithmetic runs locally, keeping salaries, debts and quotations on your own device. Change one field at a time to see which lever moves the payment most, and remember that a shorter term raises each instalment while reducing the interest that accrues. Arrangement charges, insurance and early-repayment penalties sit outside the model. Compare two offers by pushing each rate through the same amount and term, then weigh the difference in lifetime interest rather than the headline instalment alone. Overpaying each month shortens the schedule and trims interest, but that scenario lies outside this simple estimate.
