What do I need to consider before overpaying on my mortgage?

If the interest you earn on your savings account is higher than the interest you pay on your mortgage, it might be more beneficial to save. However, if your mortgage rate is higher, then paying off more of the debt might make more sense. The logic is that it is better to save paying £3 in interest than to earn £2 in interest.

However, there are still some things you need to consider before you overpay.

Many lenders have a limit on how much you can overpay by each month or in a 12-month period. Plus, you might have to pay an early repayment charge (ERC), which can also apply if you pay off your full mortgage early. You’ll need to ensure that the savings outweigh any penalties.

It’s important to prioritise your debts, so if you have any unsecured credit it will usually come with a higher rate of interest than a mortgage. If these debts are costing you more than your mortgage, it’s a good idea to pay these off first. 

Always check the terms and conditions of your mortgage and speak to your lender before you make overpayments. 

Should I still be putting money in a savings account?

If you decide to overpay on your mortgage, it can still be a good idea to keep back some savings to cover any unexpected ‘rainy day’ emergency costs, as you may not be able to request the money back from your mortgage once you’ve overpaid.

It’s also worth finding out if your interest on your mortgage is calculated monthly, quarterly or annually, to maximise the benefit of overpaying. If your interest is not due to be calculated for a few months to a year, you could put your money into a high interest savings account before using it to overpay on your mortgage.

Your mortgage provider will be able to tell you about any penalties for overpaying.
