How to Pay Off Your Mortgage Early With Extra Payments
Short answer: to pay off your mortgage early, send extra money toward principal each month, make one extra payment a year, or switch to a shorter schedule, after checking for a prepayment penalty. On a $300,000, 30-year loan at 6.5%, an extra $250 a month cuts about 8 years from the term and saves about $120,336 in interest. Whether it is the best use of the money depends on your rate, your other debts and your savings.
Key takeaways
- Extra payments go to principal, so you pay less interest on every later month.
- Starting early matters: in the first years most of each payment is interest, so early extra payments save the most.
- Make sure the servicer applies the extra to principal, and check for a prepayment penalty.
- Pay off high-interest debt, build your emergency fund and capture any retirement match before racing to pay off a low-rate mortgage.
What do extra payments actually save?
Take a $300,000 loan over 30 years at a fixed 6.5%. The monthly principal and interest payment is about $1,896.20, and total interest over 30 years is about $382,633.
| Extra payment | New payoff time | Time saved | Interest saved |
|---|---|---|---|
| $100 a month | 26.0 years | 4 years | $60,994 |
| $250 a month | 21.8 years | 8.2 years | $120,336 |
| $500 a month | 17.5 years | 12.5 years | $179,759 |
| One extra full payment a year | 24.3 years | 5.7 years | $83,984 |
Interest saved is large because the interest is charged on a balance that stays high for years. Even $100 a month removes more than $60,000 of interest in this example. These figures assume a fixed rate and no changes to your payment.
How can you pay extra?
- Add a fixed extra amount each month, and tell your servicer to apply it to principal.
- Make one extra payment a year, for example with a bonus or tax refund.
- Round up your payment, such as paying $2,000 instead of $1,896.
- Biweekly payments, half your payment every two weeks, give 26 half payments, which equals 13 full payments a year. Some servicers charge a fee for this, so you can get the same effect free by adding one-twelfth extra each month.
- Refinance to a shorter term, if rates and fees make sense. See are mortgage points worth it.
What should you check first?
- Prepayment penalty. Most mortgages have none, but check your loan documents.
- How extra payments are applied. Specify "principal only", or the servicer may treat it as an early payment of next month.
- Your other priorities. A starter emergency fund, expensive debt and any employer match come first. See your first 90 days.
Should you pay off the mortgage early or invest?
| If... | Leaning toward |
|---|---|
| Your mortgage rate is high compared with what you could reasonably earn | Extra payments, which are a guaranteed return equal to your rate |
| Your rate is low, and you have not yet used your tax-advantaged accounts | Investing first, especially for an employer match |
| You have credit card or other high-interest debt | Pay that off first |
| You have no emergency fund | Build it first, because home equity is hard to reach quickly |
| You value being debt-free and sleeping well | Extra payments, even if the maths is close |
A mortgage payoff earns a certain return equal to your rate, while investing offers a higher but uncertain return. Many people do both: a bit extra on the mortgage and regular investing. See pay off your mortgage early or invest and pay off a home loan early or invest the extra.
What are the downsides?
- Less liquidity. Money in your house is hard to get back quickly, unlike savings.
- Lost opportunity. If your rate is low, the same money invested could earn more, though with risk.
- Smaller tax benefit. If you itemize, less interest means a smaller deduction, though the saving is still larger than the lost deduction.
How do you decide?
Compare your mortgage rate with the return you could reasonably expect on an investment after tax, remembering the mortgage payoff is certain and the investment is not. Check that your emergency fund and retirement saving are on track first. If the mortgage feels like a burden, paying it down faster has value beyond the numbers. To model your own loan, see the loan payoff report, and consider how a shock would affect you with the mortgage resilience report.
