Overpaying a mortgage is not always a good idea; the optimal strategy depends entirely on your personal financial situation, your mortgage terms, and other potential uses for your spare money.
Overpaying often beats saving – but not always
You'll eat into the debt you've built up from buying a home, meaning you could be mortgage-free sooner. You don't pay interest on the amount you overpay. The money you save on interest often (but not always) beats the returns possible in savings.
Some mortgages may only allow you to overpay a certain amount each year or may charge a fee for overpayments. It is also essential to assess your overall budget to gauge if you can afford lower liquid savings. Overpaying your mortgage could mean that you have less cash available for other expenses or emergencies.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
The main cons of paying off a mortgage early include losing the mortgage interest tax deduction, facing opportunity costs (missing higher investment returns), and reducing your financial liquidity (tying up cash in your home instead of having it accessible). You might also incur prepayment penalties (though rare on conventional loans), and it can slightly lower your credit score by removing a large, established debt, according to U.S. Bank.
Savings: By making extra principal mortgage payments, you may not be able to save as much as you normally would. Monthly payments: Paying extra principal on a mortgage doesn't normally lower your monthly payment, so you'll still need to keep that regular monthly payment in mind.
If you have a fixed-rate mortgage, you'll have an annual overpayment allowance (AOA), which is the amount you can overpay each year without incurring any charges. Your AOA is equivalent to 10% of the outstanding balance of your mortgage.
If you're going well beyond your budget simply because you end up in a bidding war, it's probably time to take a step back and reassess. No matter the value of a home, if you pay more than what you can comfortably afford, then you've ultimately overpaid.
Benefits of Making Extra Payments
Improve Your Credit Utilisation Ratio: This ratio is the percentage of your available credit that you're using. Lenders like to see it below 30%. Overpaying directly lowers your balance, which improves this ratio and can have a significant positive impact on your credit score.
In 2025, interest rates for mortgages are still high. If your mortgage has a higher interest rate than the savings rate, it might be a good idea to overpay your mortgage. This can give you returns that are better than many savings accounts.
If you have a lower interest rate on your mortgage than on your savings account (for example, your mortgage is 3% and your savings is 6%), it makes financial sense to save with the higher interest rate savings account rather than overpay your mortgage.
Making an extra mortgage payment each year could reduce the term of your loan significantly. The most budget-friendly way to do this is to pay 1/12 extra each month. For example, by paying $975 each month on a $900 mortgage payment, you'll have paid the equivalent of an extra payment by the end of the year.
Speaking to 5 Live's Nihal Arthanayake, Martin Lewis said: “If your mortgage rate is higher than you can earn in savings, than overpaying mathematically adds up.” “The big advantage of overpaying your mortgage too is that it reduces the term, and you pay interest for a shorter amount of time.”
Overpaying your mortgage can have big benefits, including clearing your repayments sooner and paying less interest.
Yes, Dave Ramsey strongly advocates paying off your mortgage, calling it "Baby Step 6," because a debt-free house provides immense financial security, freedom, and a solid foundation for wealth, even arguing for it over investing at a low interest rate due to risk reduction and lifestyle benefits, though he stresses completing other steps like investing 15% first. He sees a paid-off home as a huge advantage for retirement, reducing stress and enabling career changes, and many millionaires follow this path.
The main downsides of prepaying are tying up cash that could earn more elsewhere (like investments), potential prepayment penalties from lenders, reduced liquidity for emergencies, and missing out on the time value of money, especially if your loan interest rate is low; it also means losing potential tax deductions and can complicate financial aid.
Suze Orman strongly advocates paying off your mortgage by retirement for financial freedom and peace of mind, but her advice on how varies by situation, often prioritizing a solid emergency fund and retirement savings first, especially if interest rates are low. While she pushes for paying down debt aggressively (even reducing retirement savings beyond the 401(k) match), she cautions against draining savings for low-interest mortgages if it leaves you vulnerable to job loss or emergencies, suggesting you should have a strong safety net before using savings to pay it off.
Tax considerations: You may be able to deduct home mortgage interest from your taxes. 2 However, if you pay off your mortgage, you won't be able to utilize this deduction, which could increase your taxable income. To learn more about the tax implications consider speaking with a tax advisor.
