How this calculator works

For a standard fixed-rate repayment loan, the calculator converts APR to a monthly rate and calculates the payment needed to clear the balance over the selected term. It then models optional additional monthly payments month by month.

How to use it

  1. Enter the amount you want to borrow.
  2. Add the APR and repayment term.
  3. Add any arrangement fee and say whether it is financed.
  4. Optionally test an extra monthly payment.
  5. Compare the standard repayment with your faster-payoff scenario.

Assumptions and limitations

Assumes a fixed interest rate, monthly payments and no payment holidays or early-repayment penalties. Real lender APR calculations and fees can differ.
