How much does a storage unit cost?
For a standard 10×10 unit — the size most people picture, and roughly the contents of a one-bedroom apartment — expect somewhere around $135 a month before fees, based on national market rates in mid-2026.
That is a starting point, not your bill. Where you live moves that number more than anything else. The same 10×10 unit works out around $287 a month in New York City and around $109 in Dallas-Fort Worth. Same box, more than double the price.
Here is where those figures come from, because it explains why storage prices are so hard to pin down. The storage industry does not publish average monthly prices by unit. It publishes advertised rent per square foot per year. Yardi Matrix’s May 2026 national report put that at $16.22 across the main unit types. Divide by twelve and multiply by the floor area and you get a monthly scale you can actually use.
One warning before you compare anything. These are advertised rates — what facilities put on their websites to win new customers. Your actual bill can include a required lock, mandatory insurance, an administration fee, and tax. And the introductory rate you sign up on is not the rate you keep paying.
Work out your size first, then compare prices
Pick the size before you shop, or you will end up comparing prices for units that do not fit your things.
And measure your biggest items, not just your pile. Floor space is not the whole story — a unit can be plenty big and still be useless if your sofa will not fit through the door, around the corridor, or into the elevator. Ask for the door width and the ceiling height, not just the floor dimensions. If you will need to get at things while they are in there, leave yourself a walkway too.
Now the honest caveat on that last column. Storage is not priced in a straight line. Small units almost always cost more per square foot than big ones, because the facility still has to give each one a door, a corridor, and a lock. So in the real world a 5×5 usually costs noticeably more than the $34 above, and a 10×20 often costs rather less than $270. Use the column to see the shape of the market, then get real quotes.
The math, so you can redo it for your city
Nothing here is complicated, and doing it yourself is the fastest way to sanity-check any quote you are given.
Swap in your own numbers and you have a benchmark for any quote. If a local facility wants $220 a month for a 10×10 and your metro sits near the national average, ask what you are getting for the extra $85. Sometimes the answer is good — climate control, better security, 24-hour access. Sometimes it is just what they think you will pay.
Budget for the whole period, not the first month. A $1 first month followed by eleven months at $150 is $1,651, not a bargain. Work out the total for however long you realistically need it, then compare.
What to ask before you sign
Compare like with like: same size, same access hours, same climate setting, same start date, same length of stay. Then ask these questions, because the answers are where the money hides.
If you are storing things between homes, it is worth pricing moving containers against a storage unit. A container gets delivered, loaded once, and stored — which saves you loading and unloading twice. Also read up on self-storage insurance before you accept the policy at the counter, and use our packing list so what goes in is packed to survive a few months in a box.
Where these numbers come from, and what they cannot tell you
We use a current market-level report rather than an undated national average, because averages with no date and no geography hide exactly the two things that matter most: when, and where.
What this cannot do is quote your unit. It does not separate climate-controlled from ordinary units, it does not account for one facility being newer or better located than the one next door, and it does not mix promotional first months in with regular rent. Go and look at the actual unit before you sign, then keep the signed agreement and a list of what you put in there.
