Mortgage Overpayment Calculator
Estimate how monthly overpayments could reduce your mortgage term and interest costs.
This calculator gives an estimate only and assumes the interest rate stays the same. It does not include mortgage fees, early repayment charges, overpayment limits, product changes, lender criteria, legal costs or changes to interest rates. It does not provide mortgage advice or recommend any mortgage product. Check your mortgage terms before making overpayments. Your home may be repossessed if you do not keep up repayments on your mortgage.
How this calculator works
This calculator first estimates the standard monthly repayment for the mortgage balance, interest rate and remaining term you enter. It then adds your monthly overpayment to estimate how much faster the mortgage could be repaid.
The calculator compares the estimated interest paid with and without the monthly overpayment. It then estimates how much interest could be saved and how much time could be taken off the mortgage term.
The results are estimates only. Many lenders have overpayment limits, early repayment charges or other conditions. Always check your mortgage terms and speak to an appropriately authorised mortgage adviser or lender before making mortgage decisions.
