How much is a storage unit?
A self-storage unit typically costs $40 to $300+ per month depending on size and location. A small 5x5 runs about $40-$60, a popular 10x10 averages roughly $120-$180, and a large 10x20 runs about $215-$300.
Cost breakdown
| Option | Price | Notes |
|---|---|---|
| 5x5 (small) | $40-$60/mo | Holds a closet's worth of boxes or a dresser |
| 5x10 (small) | $60-$80/mo | Furniture from a one-bedroom apartment |
| 10x10 (medium) | $120-$180/mo | About two bedrooms of furniture and boxes |
| 10x20 (large) | $215-$300/mo | Contents of a multi-bedroom home or a vehicle |
| Climate-controlled | +20-30% | Surcharge over standard units for the same size |
What drives the price
Size is the biggest factor. Nationally, a 5x5 unit averages around $40-$60 per month, a 10x10 runs roughly $120-$180, and a 10x20 typically falls between $215 and $300. Larger units cost less per square foot, so a 10x30 can be more economical per cubic foot than several small units.
Location matters just as much. Major metros like New York City and San Francisco command far higher rates than rural or suburban markets, where the same size can be 30 to 50 percent cheaper. Demand also fluctuates seasonally, with summer moving season pushing prices up.
Standard vs. climate-controlled
Climate-controlled units, which hold a steady temperature and sometimes humidity, typically cost 20 to 30 percent more than standard drive-up units of the same size. They are worth it for wood furniture, electronics, documents, artwork, or anything sensitive to heat and moisture.
Standard outdoor or drive-up units are cheaper and more convenient for loading heavy items, but offer less protection in extreme climates. For short-term storage of durable goods like tools or seasonal gear, a standard unit usually suffices.
Extra fees and how to save
Beyond the monthly rate, watch for one-time administration fees (often $20-$30), a required lock purchase, and mandatory tenant insurance that can add $10-$20 per month. Some facilities advertise low introductory rates that rise after the first few months.
To save, book online for promotions like first-month-free deals, choose a facility slightly outside the city center, and pick the smallest unit that fits your belongings. Comparing two or three nearby facilities can easily save $20-$50 per month for the same size.
Frequently asked questions
- What is the cheapest storage unit size?
- A 5x5 unit is the smallest and cheapest, averaging about $40-$60 per month nationally. It fits a small amount of boxes and a few pieces of furniture.
- Why do storage prices vary so much by city?
- Local real estate costs and demand drive the difference. Dense, high-rent metros like New York charge far more than suburban or rural areas, where land and competition are cheaper.
- Is climate control worth the extra cost?
- Yes for temperature- or humidity-sensitive items such as electronics, wood furniture, documents, and artwork. For durable goods like tools or plastic bins, a cheaper standard unit is usually fine.
