You need a temporary place to stash your stuff, you don’t have enough room for some things in your own home, or maybe you need some extra space for your business inventory.

Whatever your reason for needing a self-storage unit, you definitely want to make sure you are paying a fair price. At SpareFoot, we help consumers find and compare storage options in their area. To give you an idea of how much you should expect to pay for a storage unit, we’ve analyzed thousands of reservations made on our network in 2017 and compiled the results.

Average Cost by Size

The cost of a self-storage unit is going up.

The average cost to rent a self-storage unit is $91.14 a month. That average factors in reservations made on for all unit sizes in 2017. The current average is more than 4.5 percent higher than the $87.15 a month to rent a storage unit that we reported in 2016.

The average price per square foot is creeping higher as well. In 2017, the average price per square foot was $1.01, compared to $0.97 per square foot the previous year.
