Storage Unit Cost Calculator

Picking a storage unit comes down to two questions: how much space your belongings actually need, and what that space costs each month once climate control enters the picture. This tool answers both for 2026, which matters now that average storage prices are projected to climb 3-5% nationwide. Pinning the number down early keeps the monthly outlay from creeping past what you planned.

Sizing runs on a tiered model that maps common household volumes onto standard unit dimensions. A 5x5 unit (25 sq ft) holds roughly 50 standard moving boxes or the contents of a small bedroom, while a 10x10 unit (100 sq ft) fits a 1-bedroom apartment. Pricing draws on 2026 regional averages, for instance $60-$90 for a 5x5 non-climate controlled unit and $150-$220 for a 10x10 non-climate controlled unit, then adds a 20-35% premium when climate control is selected, which costs more to run and tends to be in higher demand.

When the volume of your load is uncertain, round up; a bit of slack beats wrestling everything into a unit that's too tight. The item most people misjudge is whether they need climate control at all, electronics, wooden furniture, and artwork can all suffer from swings in temperature or humidity. Final prices still shift with the facility's location, any running promotions, and what's available when you book, so read these figures as a starting point.
