How much does a storage unit cost per month?

Average monthly storage unit costs: 5×5 (small closet) $40–$80; 5×10 (walk-in closet) $60–$120; 10×10 (1-bedroom apartment contents) $100–$200; 10×20 (2–3 bedroom home) $150–$300; 10×30 (4-bedroom home) $200–$400. Climate-controlled units add 25–50% to the cost. Urban markets (NYC, SF, LA) are 50–100% more expensive than rural or suburban areas. First-month-free promotions are common but watch for steep rate increases after the promotional period.

When does renting a storage unit make financial sense?

Storage makes sense when you're in a life transition (moving, downsizing, divorce, renovation) with a defined timeline under 12 months. For long-term storage, the math often tilts toward selling, donating, or disposing of items: a 10×10 unit at $150/month costs $1,800/year, which exceeds the value of most stored household goods within 2–3 years. Calculate the replacement cost of what you're storing and compare it to the cumulative storage cost.
