How to Pay Off Your Mortgage Early

Being mortgage-free years early is worth six figures in saved interest. Here are the strategies that actually move the date, ranked — and the situations where extra payments are the wrong move.

The strategies, ranked by impact per dollar of pain

  1. Refinance to a shorter term (when rates cooperate). A 30→15 switch combines a lower rate with forced principal. Biggest total savings; requires closing costs and a payment you can truly carry. (Refinance calculator)
  2. A steady monthly extra. $200/month on a $320,000 loan at 6.5% saves ~$109,000 and 6 years. Automate it so willpower is not involved. (Payoff calculator)
  3. The 13th payment. One extra full payment yearly — or 1/12 monthly, or biweekly halves — cuts 4–6 years off most 30-year loans. (Biweekly calculator)
  4. Windfalls to principal. Bonuses, refunds, raises (bank half of every raise into principal before lifestyle absorbs it).
  5. Round-ups and found money. Round the payment up to the next $100; sweep cashback and side-hustle income quarterly.
  6. A recast after a big lump sum. Pay $10,000+ toward principal and pay the lender ~$250 to re-amortize: your required payment drops while the term stays — cash-flow relief, modest interest effect.
  7. Sell the stuff. Honestly the smallest lever, but decluttering sales into principal feel great and compound.

The order of operations before extra mortgage payments

When NOT to rush

If your rate is under ~4%, the guaranteed return from prepaying is small, and long-run investing has historically beaten it (with risk). If you may move within a few years, extra principal still returns at sale — but liquidity may serve you better. And never prepay if it leaves you cash-fragile: a paid-down house cannot buy groceries during a job loss. The middle path many households choose: a 30-year loan paid on a 15-year schedule voluntarily, keeping the option to stop. Model your version in the payoff calculator and watch your schedule in the amortization calculator.

Mechanics that matter

Tell your servicer — in the payment memo or portal setting — 'apply to principal'. Confirm on the next statement that the balance fell by the extra amount. Some servicers hold partial payments in suspense; a quick call fixes the setting. There is no tax downside to prepaying (you lose some interest deduction if you itemize — usually worth far less than the interest saved), and almost no modern US mortgage has a prepayment penalty, though you should verify yours.

Frequently asked questions

What is the fastest way to pay off a 30-year mortgage?
Combine a shorter-term refinance at a lower rate with steady extra principal. Without refinancing, large consistent extras — e.g., paying a 30-year on a 15-year schedule — typically halve the term and cut interest by more than half.
Is paying off a mortgage early a good investment?
It is a guaranteed return equal to your interest rate, risk-free and (mostly) tax-free in the form of interest never paid. At rates above ~6% it is hard to beat for certainty; below ~4%, investing often wins on expected value but with market risk.
What is a mortgage recast?
After a substantial principal payment (often $5,000–$10,000+), the lender re-amortizes the remaining balance over the original term for a small fee (~$250), lowering your required monthly payment. It does not change your rate or term.
Should I pay off my mortgage before retirement?
Many retirees value the security and lower monthly burn rate of a paid-off home, and it reduces sequence-of-returns risk. Others prefer liquidity. If you do aim for it, work backwards from your retirement date with the payoff calculator.
