Article takeaways
- The national average monthly rate for all storage units in 2026 is $81.70 for a 10×10, with rates ranging widely from small markets to major metros.
- Unit size is the single biggest cost factor — from a 5×5 at ~$36/month nationally to a 20×20 at ~$230/month.
- Location is the second biggest factor — the same unit can cost 3–4x more in a major market like San Francisco than in a small market.
- Climate-controlled units cost roughly 15–30% more than standard units but protect temperature-sensitive belongings from damage.
- Indoor access units can cost up to 50% more than drive-up outdoor units. Longer rental terms and upfront payment often unlock meaningful discounts.
People have a lot of stuff. Often, more stuff than they can comfortably fit in their homes or their available storage space, while trying to maintain an uncluttered life. When people are between homes, the problem of where to stash their stuff becomes even more of a predicament.
This is what makes self-storage an important service for millions of Americans—it helps people conveniently manage their belongings, business inventory, and seasonal gear without resorting to hoarding their possessions in their parents’ musty basements.
But what are the typical storage costs and monthly rent? And are they worth it?
As you might expect, the answer is: It depends! Just as real estate costs vary from place to place based on local demand and market demand, so does the cost of self-storage units and self-storage prices. For example, the average monthly rate for a 10×10 self-storage unit in the United States ranges from $35 to $250, depending on the market—from small units to large units, monthly storage rates vary widely.
You also have to factor in the age, quality, storage unit size, length of rental time, and security of the storage facility. Higher-end storage facilities will typically cost more but provide superior services.
A conveniently located but not older facility might be more affordable in the long run. In addition, self-storage prices and storage costs fluctuate throughout the year due to market demand and local demand.
Storage Unit Pricing by Size and Market
When determining how much a storage unit will cost, the most important factor in storage costs is the storage unit size—from small units and medium units to large units. The next most important factor is the local demand and marketplace where your facility is located—self-storage prices in New York, for example, differ dramatically from rural markets.
For example, the average storage unit rent in San Francisco is about $195 a month, while the average storage costs in Rancho Cordova, CA (pop. 80,000) will only cost $70 on average. The national average monthly rent and monthly rate for all units as of June 2026 was $81.70 a month, according to Storage.com’s internal data.
The chart below shows the most current price ranges and average price for the most common unit sizes in self-storage (updated June 2026):
| Unit Size | National Average (2026 YTD) | Major Market Range |
Mid-sized Market Range |
Small Market Range |
|---|---|---|---|---|
| 5×5 | $35.58 | $40–$65 | $18–$25 | $9–$15 |

Storage Facility Location
As is true with any type of real estate, local demand and location have a major impact on storage costs and self-storage prices. The more expensive the city, the more expensive self-storage is. Also, within a city, the more desirable the area you’re looking to store in, the higher the monthly rent and storage costs will be due to market demand.
The image below gives a great example of how much more storage can cost based on location within a city. Self-storage in the downtown area costs significantly more than some options just outside of it.
Climate Control
If you’re in an area with extreme temperature conditions, heat, cold, or humidity, you might be looking at climate-controlled storage units. As you can imagine, storage units with regulated temperatures cost more. Just how much do self-storage prices vary? It will depend on local demand and market demand, but climate-controlled storage unit prices are roughly 15% to 30% more than non-temperature conditions-controlled storage units. In most cases, the additional cost is worth it, though. Paying a higher monthly storage rate for climate-controlled storage will make sure your important belongings—from seasonal gear to business inventory to boat storage items—are not damaged during their time in long-term storage.
Structure Type
There are two main types of storage facilities: indoor access and outdoor with drive-up access. Outdoor structures function much like household garages with roll-up doors and drive-up access, in that each unit has a separate door accessible from the outside for easy loading and unloading. Indoor structures with indoor access tend to look more like apartment buildings, offering one main entry with a security gate and then separate doors for each unit.
Expect indoor access units to be more expensive—oftentimes up to 50% more in monthly rent than outdoor structures, especially for vehicle parking, boat storage, and large units used for cars and boats. How much indoor access storage units cost can vary based on loading and unloading access and access hours within the building or storage facility.
Security
Security features are a real factor when it comes to self-storage prices and overall value. Although you should always rent from a facility with at least some security in place (video cameras, security gate, and keypad entry), you can take things one step further by looking for sites with 24-hour security guards and unit door alarms. The more secure the facility with features like security gate entry (and the better your storage lock), the more your monthly storage rates and monthly rent will be.
Rental Agreement
Of course, one of the lesser-known self-storage unit factors is what is contained within your rental agreement. Renting a storage unit for a shorter six months is going to cost more per month than one rented for years at a time. Payments up front can also provide a fairly hefty discount (and save you the trouble of remembering to pay). If you really want to save money on renting your storage unit costs, we recommend you talk with the facility about possible discounts for advance payment and longer rental terms.
Fortunately, none of these storage costs or self-storage prices factors is set in stone. To save money with self storage, you might also want to consider how to fix things on your end—how to pack your items so that temperature conditions and climate issues are not a factor, how to maximize space in small units and medium units, and even buying a self storage lock on your own.
Is Self-Storage Worth the Cost?
To determine if self-storage is worth the storage costs and monthly rent, consider what it would cost to replace your items—from seasonal gear and business inventory to boat storage items and home projects supplies—and how long you plan to keep them in long-term storage. Don’t forget to consider the amount of time and money you would spend going to and fro to reacquire items as well. Of course, some of your items may be irreplaceable for personal sentimental reasons. When it comes to protecting priceless mementos, the monthly cost may not be your primary consideration.
Also consider this: On a square foot basis, self-storage prices are cheaper than residential real estate—especially for large units in New York and other major markets. For example, if you were to rent a bigger apartment so you can have more room for your accumulated belongings, you will pay more for that extra space than you would just renting a storage unit for the same purpose, especially with local storage unit deals.
Case in point: according to RentCafe’s April 2026 data, the average apartment rent in San Francisco works out to $5.09 per square foot, while the average storage rent in the city is $3.35 per square foot according to Storage.com’s 2026 internal data. That’s a savings of more than 34% compared to renting additional apartment space for the same purpose.
