Understanding mortgage overpayment estimates
What an overpayment changes
An overpayment reduces the outstanding balance sooner. In this estimate, that can shorten the projected term and reduce the interest charged over the remaining schedule.
Check your mortgage terms
Lenders can apply overpayments in different ways. Check your agreement for annual allowances, early repayment charges, payment recalculation rules, and whether the rate can change during the term.
- Regular overpayment: A recurring extra amount added to each monthly payment.
- Lump sum: A one-off payment that may be subject to a separate allowance.
- Rate changes: A future rate change can make the projection differ from your statement.
Use the timeline as a planning reference
Try a few realistic overpayment amounts, then compare the projected dates and total interest. Confirm the final figures with your lender before making a change to your mortgage payment.
