Overpay with confidence

Overpaying only makes sense once the essentials are covered and you have a small emergency buffer. Evenly helps couples see exactly how much is spare each month after a fair split of the bills — so you can decide together how much to put toward the mortgage.

Is it worth overpaying my mortgage?

Overpaying reduces the balance you pay interest on, so even small regular overpayments can save years and thousands in interest. Check your lender allows penalty-free overpayments (most allow up to 10% a year) and weigh it against saving or investing that money instead.

How much can I overpay?

Most UK lenders let you overpay up to 10% of the outstanding balance each year without an early repayment charge. This tool shows the impact of whatever monthly overpayment you choose.
