Mortgage calculators
Explore how an extra monthly payment or a one-off lump sum could reduce the interest and remaining term of a repayment mortgage.
This is an illustration only. Check your mortgage's overpayment allowance and possible early repayment charges before making a payment.
View all mortgage calculatorsEnter your mortgage details to compare one overpayment scenario with your current repayment schedule.
A regular overpayment adds an extra amount to each scheduled payment, while a lump sum reduces the balance once. In both illustrations the contractual payment is maintained, so the potential benefit is lower interest and an earlier estimated payoff.
Repayment-mortgage interest is charged on the outstanding balance. Reducing that balance sooner can reduce later interest, but the result depends on how your lender calculates interest and applies the payment.
Overpayment allowances and early repayment charges are mortgage-specific. Check your mortgage offer or contact your lender before making an overpayment.
You may wish to consider emergency savings, more expensive unsecured debt, pension and tax considerations, and access to cash. Anderson Reed Financial Services can help you understand the mortgage information to review, but cannot provide personal tax or pension advice.

Questions about overpayments
An overpayment is an amount paid above your normal contractual mortgage payment.
It can reduce future interest by lowering the outstanding balance sooner, but lender calculations vary.
It can where the normal payment is maintained. This calculator uses that assumption.
It is a charge that may apply under your mortgage terms if you repay more than your allowance or repay early.
Some lenders allow overpayments of around 10% of the outstanding balance each year without an early repayment charge, but this is not universal and the rules can differ by mortgage and product. Check your mortgage offer or ask your lender.
A regular overpayment is added each month; a lump sum is applied once.
Lender treatment varies. This calculator assumes the contractual payment stays unchanged.
No. This calculator is for capital-and-interest repayment mortgages only.
Calculate each part separately and confirm how your lender applies overpayments.
No. It does not include fees, early repayment charges or lender allowances.
