Early repayment savings calculator

Enter the loan amount, rate, term, how many months have already been paid, and the early repayment amount. The calculator works out how much interest that early payment saves by shortening the term.

How it is calculated

The calculation compares two totals: what would have been paid without the early repayment (remaining payment × remaining months on the original schedule) and what's paid with the early repayment (the repayment amount itself plus the same payment over the new, shorter term). The difference is the interest savings.

This uses the 'shorten the term' scheme rather than 'lower the payment' — it gives the maximum interest savings of the two standard recalculation schemes after an early repayment. If the bank lowers the payment instead, the real savings will be smaller than shown here — to compare both schemes, use the separate early loan repayment calculator with the mode selector.

The earlier the early payment is made (i.e. the more time remains until the end of the term), the bigger the savings — because the amount 'cut off' the debt would otherwise have kept accruing interest for much longer.
