Should I Pay Off My Mortgage Before I Retire?

Should you pay off your mortgage before you retire? If your rate is under about 6% and you have real money invested outside the house, the math usually favors keeping the mortgage and leaving that cash invested. A low-rate loan can cost you less than your money is capable of earning, and it keeps your savings reachable when life gets expensive. Paying it off tends to win when the rate is high, when the payment costs you sleep at night, or when you don't have other assets already working for you.

That's the short version. The longer version is where it gets interesting, because the choice depends on numbers most people never actually run. The video below walks through the same trade-off, and below it I've worked the whole thing through one couple's situation, dollar by dollar.

Watch: Patrick Shope on the math most people miss on paying off a mortgage before retirement.

Meet a couple we'll call Lou and Rita

Lou and Rita are both 62. They've done a good job, with about $1.2 million in retirement assets. They also still have a mortgage: roughly $180,000 left at 3.25%, with a payment near $1,100 a month. It's a rate they locked in a few years back, the kind you're not likely to see again anytime soon.

They came in asking the question I hear constantly in our office: "We could write a check and be done with it. Shouldn't we just pay it off?" It's a fair instinct. There's real comfort in owning your home free and clear. But before they wrote that check, I asked them to look at what the $180,000 could do if it stayed put.

The $180,000 question: pay it off or keep it invested?

Here's the calculation almost nobody does. If Lou and Rita keep that $180,000 invested and it earns more than their 3.25% mortgage rate, the money is working harder than the loan is costing them.

Let me show you the math. Say that balanced portfolio earns around 7% a year, which is roughly what a diversified mix has returned over long stretches (past results never promise future ones, so treat this as an example, not a forecast). Over ten years, $180,000 growing at 7% becomes about $354,000. That's a gain of around $174,000.

Now the other side of the ledger. Over those same ten years, the interest on their 3.25% mortgage runs somewhere around $50,000, depending on the exact amortization. They pay that from regular cash flow, the same $1,100 they're already paying.

So compare the two paths.

Even after paying every dollar of interest, keeping the mortgage leaves Lou and Rita somewhere in the neighborhood of $124,000 wealthier over a decade in this scenario. When the video models it all the way out, the gap widens: by age 85, keeping the loan and staying invested projects to over $200,000 more in total wealth than paying it off would have. That's the opportunity cost the "just pay it off" advice quietly skips.

Why inflation quietly works in their favor

Here's a piece people miss entirely. Lou and Rita's rate is fixed at 3.25%. Their payment never changes. But the dollars they use to make that payment get cheaper every year.

Think about it this way. If prices rise 3% a year, the $1,100 payment they make in 2035 costs them noticeably less in real buying power than the $1,100 they pay today, even though the number on the statement is identical. A fixed low-rate loan is one of the few things where inflation is on your side. You're paying back tomorrow's borrowed money with today's more valuable dollars, and the pile you didn't hand over keeps compounding.

The liquidity Lou didn't know he'd need

Now, some of you are thinking, "That's fine on paper, but what if we need the money?" That's exactly the second reason to think hard before paying off.

When you pay off a mortgage, that $180,000 doesn't disappear, but it does get trapped inside your home's equity. On paper your net worth looks the same. Try getting at it quickly, though, and you're looking at a home equity line: an application, an approval, fees, and time. Compare that to $180,000 sitting in an investment account, where $50,000 for a medical bill is a transfer, not a project.

This isn't hypothetical for Lou and Rita. In the scenario we modeled, Lou needs unexpected back surgery at 67 and insurance only covers part of it. Because their money stayed liquid instead of buried in the walls of the house, they moved funds in a couple of days. No loan application, no waiting on an underwriter while he's recovering. Here's something I've learned watching people go through health scares: the last thing you want during a crisis is to also be filling out a credit application. Accessible money buys calm, and calm is worth a lot at 67.

When paying off the mortgage is the right call

I don't want to leave you thinking paying it off is a mistake. It's the right move in plenty of situations. It comes down to your numbers and your temperament, not a slogan.

• Your rate is above about 6%. Once the interest cost climbs past what a portfolio can reasonably earn, the whole calculation flips, and paying it off is often the better return.
• The payment costs you sleep. If carrying a mortgage genuinely eats at your quality of life, that peace of mind can be worth more than the paper gain. I've never told anyone they were wrong to want to be debt-free.
• You want a simpler estate. Health concerns, or a wish to leave your kids a clean, uncomplicated house, are perfectly good reasons to clear the loan.
• You don't have other money working for you. If the alternative is leaving cash in a low-yield savings account, then paying off the mortgage may be the best steady return available to you.
• Paying it off would drain your reserves. If writing that check empties your emergency fund or your investment cushion, the whole comparison changes. This math only works for people who'll still have adequate assets afterward, which is part of figuring out how much you actually need to retire in the first place.

The middle ground most people miss

It's rarely all-or-nothing. There's a strategic space in between that gets overlooked.

One option: keep the mortgage but make one extra payment a year from cash flow, not from your lump sum. That shortens the loan while leaving your liquidity and your invested balance intact. Another: keep the mortgage through your higher-spending early retirement years, say from 60 to 75, when you want maximum flexibility for travel and helping family, then pay it off around 75 when life tends to simplify and you're less likely to need large chunks of accessible cash. Lou and Rita landed here. They kept the loan, set aside the payoff money in their portfolio, and gave themselves a target date to revisit it.

The real question was never "should I pay off my mortgage." It's "what's the best use of my capital for the flexibility and the life I want?" For a couple with substantial assets and a low-rate loan, the answer is often to let that cheap money keep working.

If you're staring at this decision right now, the honest move is to run your own numbers against your own comfort level, not a general rule. That's the kind of thing we're glad to sit down and work through with you. You can start a conversation with us and we'll model both paths on your actual rate, savings, and timeline.

For folks who've built real assets and locked in a cheap mortgage, the goal usually isn't to be debt-free. It's to have more wealth and more flexibility. Sometimes that strategic debt gets you there faster than paying it off ever could.
