Frequently Asked Questions
What is a mortgage overpayment?
An overpayment is paying more than your agreed monthly mortgage instalment. This can reduce interest, shorten your mortgage term, or both, depending on lender terms.

How much can I overpay?
Most lenders allow up to 10–20% of the outstanding balance per year without penalty. Check your mortgage agreement for exact limits and possible fees.
Does overpaying affect my monthly payments?
Yes. Overpayments can either reduce your monthly payment while keeping the term the same or keep the payment constant and shorten the mortgage term. The calculator shows both scenarios.
Are there fees for overpaying?
Some fixed-rate mortgages may charge early repayment fees if overpayments exceed allowed limits. Always check your mortgage terms before making extra payments.
How much interest can I save?
Interest savings depend on remaining term, interest rate, and overpayment amount. The calculator provides a personalised estimate of potential savings.
Can I make one-off or regular overpayments?
Yes. The calculator supports both lump-sum and monthly overpayment options, helping you plan the most effective repayment strategy.
Will overpayments affect my credit rating?
No. Overpayments are simply additional payments towards your mortgage and do not negatively impact your credit score.
Can I reverse an overpayment if my finances change?
Most lenders do not allow reversing overpayments, but you can adjust future overpayments. Always discuss options with your lender.
Should I consult a mortgage advisor before overpaying?
Absolutely. The calculator gives estimates, but a mortgage advisor can optimise your overpayment plan, ensure compliance with lender rules, and maximise interest savings.
