How Much Does a Self-Storage Unit Cost?
Last updated: April 30, 2026 by the How Much Does That Cost? editorial team. Estimates are informational - see our methodology.
A self-storage unit costs $60 to $250 per month on average, with most people paying around $130 for a standard 10x10 unit. Price scales directly with unit size, and climate-controlled units typically cost 20-40% more than standard units.
A small 5x5 unit for a few boxes and seasonal items can run as little as $35-$60 per month, while a large 10x20 or bigger unit for a full household can cost $250-$400 or more, especially in expensive metro areas.

Cost Breakdown
How a typical project budget breaks down by category.
| Category | Estimated Cost |
|---|---|
| Base monthly unit rent | $40 – $220 |
| Climate control surcharge | $0 – $60 |
| Administrative/setup fee (one-time, averaged) | $5 – $15 |
| Insurance/protection plan | $10 – $25 |
| Lock/security add-on | $5 – $15 |
What Affects the Cost
Unit size
Monthly rent scales directly with square footage — a small 5x5 unit for boxes costs a fraction of what a 10x20 unit for full household furniture costs.
Climate control
Climate-controlled units maintain a consistent temperature and humidity range to protect wood furniture, electronics, and documents, typically costing 20-40% more than standard units.
Location and local real estate costs
Storage pricing tracks local land and rent costs closely — units in dense, expensive metro areas can cost double what the same size unit costs in a rural or suburban market.
Unit access and location within the facility
Ground-floor, drive-up units that let you load directly from your car typically cost more than upstairs units requiring an elevator or interior hallway.
Length of rental commitment
Facilities often offer discounted rates for long-term or prepaid contracts, while short-term or month-to-month renters typically pay the standard listed rate.
Promotional pricing
Many facilities advertise a discounted rate (like 50% off) for the first month or two that reverts to full price afterward, which can make comparing quotes tricky.
Cost by Storage Unit Size
| Storage Unit Size | Typical Cost |
|---|---|
| 5x5 ft (25 sq ft) | $40 – $90 |
| 5x10 ft (50 sq ft) | $60 – $130 |
| 10x10 ft (100 sq ft) | $95 – $190 |
| 10x15 ft (150 sq ft) | $130 – $250 |
| 10x20 ft (200 sq ft) | $170 – $320 |
DIY vs. Hiring a Professional
Doing it yourself
Renting a traditional self-storage unit and hauling your own items to and from the facility is the cheapest option, giving you full control over access hours and what you store, but it requires your own vehicle and labor every time you need something.
Hiring a professional
Full-service "valet" storage companies pick up your items, store them in a warehouse, and deliver them back on request (often photographing and cataloging each item), typically costing more per month but eliminating the trips to a facility.
Bottom line: A standard self-storage unit is the better value if you'll visit occasionally or need to store large furniture; valet storage is worth the premium mainly for smaller loads you rarely need to access.
Ways to Save
- Compare a few facilities directly by phone — advertised online rates are often negotiable, especially at partially-empty facilities.
- Choose the smallest unit that realistically fits your items rather than sizing up for extra room you won't use.
- Skip climate control for items that don't need it (tools, outdoor gear, vehicles) and reserve it only for furniture, electronics, or documents.
- Ask about first-month promotional discounts, but confirm the standard rate you'll pay afterward before committing.
- Pay for several months upfront if the facility offers a prepay discount and you know you'll need the unit long-term.
- Choose an upstairs or interior unit over a drive-up unit if you don't need frequent vehicle access — it's usually cheaper.

Frequently Asked Questions
How much does a storage unit cost per month?
A self-storage unit averages about $130 per month, typically ranging from $60 to $250 depending on unit size, climate control, and your local market.
How much does a 10x10 storage unit cost?

Is climate-controlled storage worth the extra cost?
Climate control is worth it for wood furniture, electronics, photos, documents, and musical instruments, which can warp or degrade in extreme heat, cold, or humidity — it's less necessary for tools, outdoor equipment, or plastic-bin items.
What size storage unit do I need?
A 5x5 or 5x10 unit fits boxes and small furniture from a studio or 1-bedroom, a 10x10 fits a 1-2 bedroom apartment, and a 10x15 or 10x20 unit is typically needed for a full 3+ bedroom household.
Do storage facilities require a long-term contract?
Most self-storage facilities rent month-to-month with no long-term commitment, though some offer discounted rates if you prepay for several months or a full year in advance.
