Average storage unit cost
The average US self-storage unit costs roughly $110 to $150 per month, with a 10x10 — the most commonly rented size — averaging about $135. That average is a weak planning number: the same unit ranges from under $70 in a rural market to over $300 in a coastal metro.

What the average actually covers
| Unit size | Typical range | Midpoint | Share of the market |
|---|---|---|---|
| 5x5 | $40–$75 | $58 | Small — mostly overflow storage |
| 5x10 | $55–$110 | $83 | High — studios and single rooms |
| 10x10 | $90–$180 | $135 | Highest — the default full-apartment unit |
| 10x20 | $160–$310 | $235 | Moderate — houses and vehicles |

Why the average is a poor planning number
Three variables each move the price further than the difference between "average" and what you will pay.
- Market. Land cost dominates. A 10x10 in Manhattan and a 10x10 in rural Ohio are the same box with a threefold price difference.
- Timing. Peak season is May to September, and rates within a single facility move week to week with occupancy.
- Position in the building. Ground floor and drive-up units carry a 10–25% premium over an upper floor with elevator access.
An average is useful for one thing only: sanity-checking a quote that is wildly out of range. For a budget, use the size-specific range in your market type — see cost by size.
Average by market type
| Market type | 10x10 standard | 10x10 climate-controlled |
|---|---|---|
| Northeast metro (NYC, Boston) | $122–$342 | $155–$437 |
| West Coast metro (SF, LA, Seattle) | $117–$333 | $150–$426 |
| Southern metro (Atlanta, Dallas, Miami) | $86–$225 | $109–$288 |
| Midwest metro (Chicago, Minneapolis) | $90–$234 | $115–$299 |
| Suburban, most states | $77–$198 | $98–$253 |
| Rural and small town | $54–$162 | $69–$207 |
Reference ranges scaled by market type, not local quotes.
Three quotes that can all be reasonable
| Quote | What it may represent | What to verify |
|---|---|---|
| $75 for a 10×10 | Rural or low-occupancy market, upper floor, introductory rate | The month-three rate and elevator access |
| $135 for a 10×10 | Typical suburban standard unit near the national midpoint | Admin fee, lock, insurance and renewal notice terms |
| $250 for a 10×10 | Coastal metro, drive-up access or climate control | Whether a nearby interior unit removes the premium |
Examples explain why one national average cannot validate a local quote on its own.
What you will actually pay in month one
Sizing comes before pricing — see storage unit size calculator and the /storage-unit-sizes/10x10/ if you have not fixed the size yet. The advertised rate is not the invoice. A $90 10x10 typically becomes $128–$180 in month one once the administration fee, a disc lock and the first month of mandatory insurance are added — and that is before the introductory rate expires.

Related questions
What is the average cost of a storage unit per month?
Roughly $110–$150 per month across all sizes in the US, and about $135 for the most common 10x10. Your own figure depends far more on market and size than on any national average.
Has storage got more expensive?
For a size-by-size breakdown see the full price table by size, and estimate the monthly cost for your own total. Street rates have risen materially since 2020, driven by construction cost and demand from smaller housing. Existing-customer increases of 8–15% within the first year are now standard practice rather than an exception.
What is the cheapest storage unit size?
A 5x5 at $40–$75 per month, though it is also the most expensive per square foot. If you need more than one 5x5, a single 5x10 is almost always cheaper.
