It always starts the same way. You’re moving, downsizing or clearing out a parent’s house, and you need somewhere to put things. Just for a few months.
Then a few months becomes a few years.
A 10-by-10 storage unit now rents for an average of $80.43 a month nationwide, according to May 2026 figures from SpareFoot, a storage rental marketplace. That’s about $965 a year — not to use your stuff, just to keep it.
You’re far from alone. About 16.7 million U.S. households, or roughly 1 in 8, rented self-storage in 2024, according to a 2025 study by the Self Storage Association, the industry’s trade group.
And people don’t leave quickly. The average customer now stays 18.5 months, according to SpareFoot.
Here’s the math I’d want you to see before you put a unit on auto-pay. Keep that unit five years, and you’ve spent about $4,825. Put that $965 a year into an investment earning 7% a year instead, and after five years you’d have about $5,550.
So, is your unit earning its keep? Here are six signs it isn’t.
1. You can’t name what’s in it
Try this. Without opening the door, write down everything in your unit.
If you get stuck after a dozen items, you’ve learned something important: You’re paying rent to protect things you don’t remember owning. If you don’t miss it, you don’t need it.
2. You’ve paid more in rent than the stuff is worth
Consumers’ Checkbook, a nonprofit consumer group, makes the point bluntly: For most renters, it doesn’t take long before the rent they’ve paid tops what their stuff is worth.
Do the math on yours. Add up what you’ve paid since you moved in. Then estimate what it would cost to replace what’s inside with good used versions. For a lot of people, the rent wins, and it isn’t close.
As a CPA, I’d tell you the money you’ve already spent is gone. The only question that matters is whether the next year of rent is worth it.
3. You’re storing it for ‘someday’
The house you’ll buy someday. The grandkids who’ll want the dining set someday. The garage you’ll finally clean out someday.
Someday has a monthly bill. If you’re saving furniture for a family member, call them today and ask. If the answer is anything short of “yes, I’ll pick it up,” let it go.
If you’re downsizing, plan for this before you move. Storage is a cost that catches a lot of people off guard. For others, see “9 Hidden Costs of Downsizing That Catch Retirees Completely by Surprise.”

4. Your rent has crept up since you moved in
That low price that got you in the door may not be the price you’re paying now.
Extra Space Storage, the largest operator in the country, told investors in its latest annual report that existing tenants generally get rate increases at least once a year.
In February, New York City’s consumer protection agency sued Extra Space, alleging that once customers moved in, the company quickly raised prices, often dramatically.
In July, Extra Space settled for $1 million in restitution to customers plus more than $700,000 in civil penalties, and it must now warn NYC customers properly before a price hike.
Dig out your original lease and compare it with your latest bill. Then check what your own facility is advertising to new customers for the same size unit.
If there’s a big gap, ask for the new-customer rate. If they say no, it may be time to move out.
5. You’re paying for climate control your stuff doesn’t need
A climate-controlled unit costs 10% to 25% more than a standard one, according to SpareFoot. On an $80 unit, that’s an extra $8 to $20 a month.
Some things deserve it. But the stuff that needs protection most — family papers and photos — probably shouldn’t be in a storage unit at all.
The National Archives recommends keeping them below 75 degrees and below 65% relative humidity, and not in a damp basement, a garage or a hot attic. In other words, bring the photo albums home. Then ask whether what’s left is worth the premium.
6. You haven’t opened the door in a year
If you haven’t needed anything in there for 12 months, the unit isn’t storage anymore. It’s a very expensive attic.
Pick a weekend and go through it. Even if you don’t empty it, you may be able to move what’s left into a smaller unit. A 5-by-5 averages $34.89 a month, according to SpareFoot. Downsizing from a 10-by-10 would save about $45 a month, or about $546 a year.
How to empty it without losing money
Sell what’s worth selling. Some of it may surprise you; check out these household items you can sell for fast cash and the retailers that want to buy your clutter.
Donate the rest, and get a tax break if you can. Here are the IRS’ rules to know first:
- Clothing and household items must be in what the IRS calls “good used condition or better” to be deductible.
- You generally have to itemize to deduct donated goods. The new deduction for people who don’t itemize, starting with tax year 2026, covers only cash gifts.
- If you deduct more than $500 in donated items, you’ll need to file Form 8283.
- Items, or groups of similar items, valued at more than $5,000 generally need a qualified appraisal.
One more thing: Don’t just stop paying. In Florida, for example, state law gives a storage facility a lien on everything in your unit, and after written notice it can sell your belongings to cover what you owe. Laws vary by state, so close out your account properly.
