The decision to overpay your mortgage or save extra money largely hinges on your mortgage interest rate, the return on your savings, and your personal financial objectives.
Benefits of Overpaying Your Mortgage
Overpaying reduces your loan balance faster, saving you interest over the long term. According to MoneySavingExpert.com, if your mortgage rate is similar to or higher than your savings rate, overpaying is typically the better choice. For instance, on a £250,000 mortgage over 25 years at 5%, overpaying £150 monthly could cut the term by roughly four years and save over £40,000 in interest.
When to Choose Saving Instead
If your savings account offers a competitive rate equal to or higher than your mortgage rate, saving may be more advantageous. Savings provide liquidity for emergencies, home repairs, or job loss. Financial experts recommend maintaining an emergency fund covering three to six months of essential expenses before making significant overpayments.
Check for Penalties
Most lenders allow overpayments of up to 10% of your outstanding balance per year without penalty on fixed-rate deals. On standard variable rates or trackers, you can often overpay freely, though SVRs may be expensive.
Prioritize Higher-Interest Debts
Before overpaying your mortgage, clear any debts with higher interest rates, such as credit cards, personal loans, council tax arrears, or utility bills. Mortgage debt is considered a priority, but it should not compete with more expensive borrowing.
Expert Insight
George Abouzolof, Senior Mortgage Advisor at Clifton Private Finance, notes: “Choosing whether to overpay your mortgage is entirely within your control. It’s one of the few levers homeowners can pull to improve their long-term financial position. Even small overpayments make a noticeable difference, especially early in the term. Overpaying works best when you’ve already built a strong emergency savings buffer and cleared higher-interest debts.”
