Paying more than your required monthly amount can cut the interest you pay and clear your mortgage sooner. But limits and charges apply, so it pays to check the rules first.

## Key information

- Overpaying reduces your balance, so you pay less interest overall
- Many fixed deals allow overpayments of up to 10% of the balance each year
- Going over the limit can trigger an early repayment charge
- Overpaying is not always the best use of money — weigh it against savings and other debts

## How overpaying helps

Because mortgage interest is charged on the amount you still owe, reducing the balance faster means less interest over the life of the loan and, often, a shorter term. Even modest regular overpayments can make a meaningful difference over many years.

You can usually choose to keep your term the same and lower future payments, or keep payments the same and shorten the term — ask your lender how each option would work for you.

## Overpayment limits and charges

Fixed and discounted deals commonly allow you to overpay up to a set amount each year — often 10% of the outstanding balance — without penalty. Overpay beyond that during the deal period and you may face an [early repayment charge](/mortgages/mortgage-fees#early-repayment-charges). Tracker and standard variable rate mortgages often allow unlimited overpayments, but you should always check your own mortgage terms first.

## Is overpaying worth it?

Overpaying is not automatically the best move. It can make sense if your mortgage rate is higher than the interest you could earn on savings, but it is usually wise to [clear more expensive debts first](/debt-money-problems/struggling-with-debt) and to keep an [accessible emergency fund](/banking-savings/savings-accounts). Money used to overpay is generally locked into the property and harder to get back than savings.

## Your rights

- Your lender must tell you clearly what overpayments are allowed and whether any charge applies.
- You are entitled to ask how an overpayment will be applied — to reduce your term or your monthly payment.
- If an overpayment is handled incorrectly you can complain and, if unresolved, contact the Financial Ombudsman Service.
