What Is a Mortgage Term and How to Choose One

Mortgage Term Explained

The mortgage term is simply the number of years you have to repay your mortgage in full. In the UK, the most common mortgage term is 25 years, but terms can range from as short as five years to as long as 40 years, depending on the lender and your circumstances.

It is important to distinguish between the mortgage term and the deal period. Your deal period is the length of your introductory rate (for example, a two-year or five-year fix). Your mortgage term is the overall repayment period. When you remortgage, you can choose to keep the same remaining term, extend it, or shorten it.

The term you choose directly affects two things: your monthly payment amount and the total amount of interest you pay over the life of the mortgage. A longer term means lower monthly payments but more interest overall. A shorter term means higher payments but less interest in total.

How the Mortgage Term Affects Your Payments

To illustrate the impact, consider a £200,000 repayment mortgage at an interest rate of five per cent. Over a 25-year term, your monthly payment would be around £1,169, and you would pay approximately £150,800 in total interest. Over a 30-year term, the monthly payment drops to around £1,074, but total interest rises to roughly £186,500.

That is a difference of nearly £36,000 in interest for what might feel like a modest reduction in monthly payments. On the other hand, if you shortened the term to 20 years, your monthly payment would increase to around £1,320, but you would save around £33,000 in total interest compared to the 25-year term.

When remortgaging, it is worth considering whether you can afford higher monthly payments in exchange for paying less interest overall and being mortgage-free sooner.

Choosing the Right Term When Remortgaging

When you remortgage, you have the opportunity to adjust your mortgage term. Here are some factors to consider:

• Your age and retirement plans – many lenders have a maximum age at which the mortgage must be repaid, often 70 or 75. If you are approaching retirement, a shorter term may be preferable.
• Monthly affordability – a longer term reduces your monthly payments, which can be helpful if your budget is tight. However, make sure you are not paying significantly more interest over time.
• Your financial goals – if you want to be mortgage-free by a certain age, work backwards to determine the term you need.
• Interest rates – when rates are high, some borrowers extend their term to keep payments manageable, planning to shorten it again when rates fall.

There is no one-size-fits-all answer. The right term depends on balancing affordability with your long-term financial goals.

Can You Change Your Mortgage Term Later?

Yes. Each time you remortgage, you can choose a new term. If your income has increased, you might shorten the term to pay off your mortgage faster. If you are facing financial pressure, extending the term can lower your monthly payments.

Some lenders also allow you to make overpayments, which effectively shortens your term without formally changing it. Most mortgage deals permit overpayments of up to ten per cent of the outstanding balance each year without incurring a penalty.

It is worth reviewing your mortgage term at every remortgage point to ensure it still aligns with your circumstances and goals. A good mortgage broker can help you model different scenarios to find the best balance between affordability and total cost.
