Paying off your mortgage early is one of the most satisfying financial milestones you can hit — but it isn't always the right move. The decision comes down to your mortgage rate, your alternatives (savings, investing, pension), and how much it would cost in ERCs to do it now versus waiting.
You'll be mortgage-free 6 years 9 months earlier
and save £46,940 in interest.
| Without | With overpay | |
|---|---|---|
| Term | 25 years | 18 years 3 months |
| Total interest | £156,277 | £109,338 |
| You save | £46,940 · 6y 9m |
A lower interest rate could save you thousands more on top. See if you could remortgage to a better deal.
We may receive a commission if you remortgage through a partner broker. This never affects the rate you're offered.
Your mortgage rate beats what you can earn (after tax) on savings or low-risk investments.
You have a fully funded emergency fund and no higher-interest debt.
You've captured employer pension matching and higher-rate tax relief.
Either you can stay within the 10% annual cap, or you're on SVR (no ERC).
You're still in a fixed deal with a big ERC — wait until the fix ends to avoid the charge.
You don't have a cash emergency fund — build that first.
You're a higher-rate taxpayer with unused pension allowance — pension tax relief usually wins.
Mortgage freedom changes your relationship with work, risk and time. Many people who could mathematically get a higher return investing still choose to clear the mortgage for the peace of mind. That's a valid choice — just go in with eyes open about the trade-off.
