A storage unit costs an average of $150 to $240 per month across national datasets, with small 5×5 units starting around $50 to $75 and large units running $190 to $300 or more.1,2,3,4 The final price depends on unit size, climate control, location, and contract length. Prices below are national averages* for 2026.

The averages disagree mostly because of what they measure. StorageCafe tracks listed street rates, move.org averages the quotes it collected, and Angi publishes a wider cost range. The size-by-size numbers land in a much narrower band, as the table below shows.1,2,3
Cost by unit size (moveBuddha)
| Unit size | Standard | Climate-controlled |
|---|---|---|
| 5 x 5 | $60 | $85 |
| 5 x 10 | $77 | $106 |
| 10 x 10 | $115 | $152 |
| 10 x 15 | $150 | $190 |
| 10 x 20 | $190 | $240 |
| 10 x 30 | $234 | $258 |
| 20 x 20 | $259 | $270 |
StorageCafe puts the national average for a small 5×5 unit at about $52 per month and a 5×10 at about $74, with big-city prices running far higher: a 5×5 averages $128 in Boston against $30 in Oklahoma City.2
Climate control premium
Every source agrees climate control costs extra, but not by how much. move.org puts climate-controlled units at about $190 per month, only $10 above its overall average.1 StorageCafe shows a 10×10 climate-controlled unit at $134 against $119 standard.2 Forbes says to expect at least $25 to $30 more per month.4 The moveBuddha size table above shows the premium growing with unit size, from $25 on a 5×5 to $50 on a 10×20. Across sources the premium runs from about $10 to $50 per month, so ask each facility for both prices before deciding.
Fees and add-ons
| Item | Cost | Source |
|---|---|---|
| Storage insurance | $10 – $40 per month (Angi); from about $10 per month (move.org) | two sources |
| Packing help | from about $280 | Angi |
| Container or on-demand transport | $50 – $125 per round trip | Angi |
| Long-term contract discount | $5 – $30 off the monthly price | Angi |
Some renters’ and homeowners’ policies cover goods in storage, so check your own policy before buying the facility’s insurance.3
Vehicle storage
Specialized vehicle storage averages about $210 per month in the move.org quote data, with RV-sized spaces often costing more.1 StorageCafe puts car storage units at about $145 per month nationally.2 The two figures measure different mixes of vehicles and facilities, so treat them as a range of $145 to $210 rather than a contradiction.
Ways to pay less
Three moves consistently cut the bill. First, shop around: move.org found prices vary enough between companies to save upwards of $100 by shopping around.1 Second, sign a six-month or one-year contract if you know your timeline, worth $5 to $30 off the monthly rate.3 Third, rent in winter when demand drops and deals are more common.4 Choosing the smallest unit that fits matters more than any of these: moving down one size in the moveBuddha table saves $17 to $50 per month, every month.5
