Learning CenterHow to cut 10 years off a 30-year mortgage
To cut about 10 years off a 30-year mortgage, pay extra toward principal—on a $300,000 loan at an illustrative 6.5%, roughly $400 more per month gets you close to a 20-year payoff. Biweekly payments, annual lump sums, refinancing to a 15- or 20-year term, or a recast are other paths, each with different flexibility.

How can I cut 10 years off a 30-year mortgage?
| Strategy | How it works | Flexibility |
|---|---|---|
| Extra principal monthly | Add a fixed amount to each payment, applied to principal. | High—stop anytime |
| Biweekly payments | Half-payment every two weeks = 13 full payments a year. | Medium |
| Annual lump sum | Apply a bonus or tax refund to principal once a year. | High |
| Refinance to 15- or 20-year | Shorter term, usually lower rate, higher required payment. | Low—payment is locked in |
| Recast | Pay a lump sum, lender re-amortizes to lower the payment. | Lowers payment rather than term |
How much extra do I need to pay to cut 10 years?
Illustrative example: $300,000, 30-year fixed at 6.5%
Regular principal and interest: about $1,896/mo.
Add about $400/mo to principal → paid off in roughly 20 years, saving roughly $140,000+ in interest.
Add about $200/mo → paid off in roughly 24–25 years.
Illustrative only, not a commitment to lend. Results depend on your rate, balance, and when you start.
Make sure extra payments are marked "apply to principal," and confirm your loan has no prepayment penalty (most standard loans don't). Test amounts in the payment calculator.
Do biweekly payments really work?
Yes—26 half-payments equal 13 full payments a year, one more than normal. On a typical 30-year loan, that alone can shave roughly four to six years off. Be careful with third-party biweekly services that charge fees; you can get the same result for free by adding one-twelfth of a payment to each monthly payment.
Should I refinance to a 15-year instead?
Refinance to 15-year
Usually a lower rate and far less total interest—but a required payment that can be several hundred dollars higher. Best when your income is stable and you have solid reserves. See 15-year fixed.
Keep the 30-year + prepay
Lower required payment and full flexibility; you choose when to pay extra. Best if income varies or you value a cushion. See 30-year fixed.
A 20-year term is a middle ground worth pricing. Refinancing also has closing costs, so run the break-even.
What is a mortgage recast?
With a recast, you pay a lump sum toward principal and the lender recalculates your payment over the remaining term. It lowers your monthly payment but doesn't shorten the loan by itself—though you can keep paying the old amount to finish sooner. Recasts typically carry a modest fee, aren't available on every loan (FHA and VA generally don't allow them), and require a minimum lump sum.
Is paying off my mortgage early the right move?
- Build an emergency fund first—prepaid principal is hard to get back out.
- Pay off higher-interest debt like credit cards first.
- Keep contributing enough to get any employer retirement match.
- Compare your mortgage rate with what that money could reasonably earn elsewhere.

How do the strategies compare on the same loan?
| Approach ($300,000 at an illustrative 6.5%) | Monthly outlay | Approx. payoff |
|---|---|---|
| Standard 30-year | ~$1,896 | 30 years |
| 30-year + $200 extra | ~$2,096 | ~24–25 years |
| 30-year + biweekly (13th payment) | ~$2,054 equivalent | ~24–25 years |
| 30-year + $400 extra | ~$2,296 | ~20 years |
| Refinance to 15-year (if rate is lower) | higher required payment | 15 years |
Illustrative only, not a commitment to lend. Actual rates, costs, and terms vary by borrower, property, program, and market.
The earlier you start, the more each extra dollar does—early payments are mostly interest, so extra principal then has the biggest effect.
Frequently asked questions
How can I pay off my 30-year mortgage in 20 years?
Add extra principal each month—on a $300,000 loan at 6.5%, roughly $400 more per month gets close to 20 years. Illustrative only.
Do biweekly payments save money?
Yes. They add one extra full payment per year, which can cut several years and meaningful interest. Avoid fee-based services.
Is a 15-year mortgage better than paying extra on a 30-year?
A 15-year usually has a lower rate; a 30-year with extra payments offers flexibility. The right choice depends on income stability and reserves.
Does a recast shorten my loan?
Not by itself. It lowers the payment. Keeping your old payment amount after recasting can shorten the loan.
Is there a penalty for paying off a mortgage early?
Most standard residential mortgages have no prepayment penalty, but check your note or ask your servicer.
Should I pay extra principal or invest the money?
It depends on your rate, risk tolerance, and goals. Paying down a mortgage is a guaranteed return equal to your rate; investing may earn more or less. Many people do some of both after building an emergency fund.
