# Should you pay off your mortgage early?

Paying extra on a mortgage earns exactly your interest rate, guaranteed. Whether that's a good deal depends on what else the money could do, how much cash you'd have left, and how you feel about debt. Here is a way to decide, with the math shown.

By [Ashutosh Anand](https://ownedoutright.com/about/) · Updated September 23, 2026 · [How we calculate](https://ownedoutright.com/methodology/)

**The short version.** Deal with the basics first: an emergency fund, any employer retirement match and high-interest debt. After that, compare your mortgage rate with what you'd realistically earn investing after tax. At 6% or more, prepaying is a strong, risk-free choice. Below about 4%, investing has usually been the better bet, but it isn't guaranteed.

## Do these first

Extra mortgage payments are hard to get back, so they come after the things that protect you or pay more:

- **An emergency fund.** Money you've sent to the lender isn't available if you lose your job; your payment stays the same no matter how much you've prepaid. Keep several months of expenses in cash first.
- **The full employer retirement match.** A 50% or 100% match on your contribution beats any mortgage rate.
- **High-interest debt.** Credit cards at 20% or more, and car or personal loans above your mortgage rate, should go before the mortgage.
- **PMI, if you pay it.** Extra principal that gets rid of PMI sooner earns your rate plus the premiums you stop paying. See [how to get rid of PMI](https://ownedoutright.com/us/guides/how-to-get-rid-of-pmi/).

## What prepaying earns you

Every extra dollar of principal stops being charged interest for the rest of the loan. So the return on a prepayment is your mortgage rate: 6.5% on a 6.5% loan, with no market risk. There's no tax on that saving either, unless you itemize and lose some of the mortgage interest deduction (more on that below).

Take a $300,000 balance at 6.5% with 25 years left. The principal and interest payment is $2,025.62 and the loan will charge $307,687 of interest from here. Adding $500 a month pays it off 9 yrs 1 mo early and saves $125,589. On the same balance at 3%, the same $500 saves $46,062, far less, because there's far less interest to avoid.

## Prepay or invest: the same money, two ways

Two households have that loan and $500 a month to spare. One prepays, and once the house is paid off invests the whole payment it no longer has to make, until the date the loan would have ended. The other pays the normal payment and invests the $500 from day one. Here's what each has at the end, at different investment returns:

| Investment return | Prepay, then invest | Invest from the start | Ends up ahead | | --- | --- | --- | --- | | 3% a year | $316,002 | $223,004 | Prepaying | | 4% a year | $331,296 | $257,065 | Prepaying | | 5% a year | $347,551 | $297,755 | Prepaying | | 6% a year | $364,835 | $346,497 | Prepaying | | 7% a year | $383,220 | $405,036 | Investing | | 8% a year | $402,784 | $475,513 | Investing |

| Investment return | Prepay, then invest | Invest from the start | Ends up ahead | | --- | --- | --- | --- | | 3% a year | $220,590 | $223,004 | Investing | | 4% a year | $230,421 | $257,065 | Investing | | 5% a year | $240,821 | $297,755 | Investing | | 6% a year | $251,827 | $346,497 | Investing | | 7% a year | $263,478 | $405,036 | Investing | | 8% a year | $275,816 | $475,513 | Investing |

Calculated with the same engine as our calculators. Returns compound monthly and are steady; taxes, fees and inflation are left out so the comparison isolates the two rates. Both households own the home outright at the end.

The pattern is the whole answer in one line: **investing wins only when it earns more than your mortgage rate**, after tax and fees. Everything else is about how sure you are of that return.

- **Returns aren't steady.** The table assumes the same return every year. Real markets have bad decades, and a bad stretch just before you need the money hurts. Prepaying has no such risk.
- **Taxes change the target.** In a 401(k) or IRA, investment growth is sheltered, which favors investing. In a taxable account, gains and dividends are taxed, so investing needs to beat your rate by more.
- **Behavior matters.** The investing household only wins if it really invests the money every month for decades. Many people find a smaller mortgage easier to stick with.

## The tax deduction is smaller than people think

Mortgage interest is deductible only if you itemize. For 2026 the [IRS standard deduction](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill) is $16,100 for single filers and $32,200 for married couples filing jointly. In the 6.5% example, the first year's interest is $19,354. A married couple would need more than $12,846 of other deductions, such as state and local taxes and charity, before that interest saves them anything. Most households take the standard deduction, so for them the deduction doesn't change the math at all. The deduction also applies only to interest on up to $750,000 of mortgage debt for loans taken out after December 15, 2017 ([IRS Publication 936](https://www.irs.gov/publications/p936)).

## Money in the house is hard to get back

Prepaying doesn't lower your required payment on a standard fixed-rate loan; it only moves the end date. If money gets tight, the only ways to reach that equity are selling, a cash-out refinance or a home equity loan, and you have to qualify for the last two at the moment you need them. A recast can lower the payment after a large prepayment; see [mortgage recast vs refinance](https://ownedoutright.com/us/guides/mortgage-recast-vs-refinance/).

That's why the order above matters, and why a middle path is common: prepay some, invest some, and keep the cash cushion intact.

## When paying off early makes the most sense

- Your rate is high, roughly 6% or more, and the basics above are covered.
- You're within 10–15 years of retiring and want lower fixed costs when your paycheck stops.
- You pay PMI and extra principal would end it soon.
- You've already maxed out tax-sheltered retirement accounts and would otherwise invest in a taxable account.
- Being debt-free matters to you. That's a legitimate reason; the guaranteed return and the peace of mind are real.

## When it probably doesn't

- Your rate is low, under about 4%, and you have decades to invest.
- You don't yet have an emergency fund, are missing an employer match, or carry high-interest debt.
- Your mortgage has a prepayment penalty. They're uncommon now and federal rules limit them, but check your note or Closing Disclosure; the [CFPB explains what to look for](https://www.consumerfinance.gov/ask-cfpb/what-is-a-prepayment-penalty-en-1957/).

## If you decide to prepay, do it right

- Use your servicer's "additional principal" option, not "next payment", so the money reduces the balance now.
- Check the next statement: the principal balance should drop by your regular principal plus the extra.
- Avoid third-party biweekly programs that charge fees for something you can do yourself.
- Re-check the decision when rates, your income or your goals change.
