Endless Storage
2026 Storage Cost Guide

How much does a storage unit cost?

Nationally, a 10×10 unit averages about $80 a month — but in big cities it's 2–3× that ($219 in LA). And most people rent a whole unit and fill half of it. If you're storing boxes, there's a cheaper way — enter your ZIP below.

Average storage unit cost by size

Self-storage is priced by the square foot. Here are the national averages — and how many boxes actually fit.

5×10 50 sq ft ~$51/mo A small room · ~30–40 boxes
10×10 100 sq ft ~$80/mo 1–2 rooms · ~60–80 boxes

10×20 200 sq ft ~$130/mo 3–4 rooms / a small house

National averages, SpareFoot, 2026. Local prices swing 2–3× (a 10×10 is ~$80 nationally but ~$219 in Los Angeles). Climate control adds ~15–30%. Use the calculator for your ZIP.

What affects the price?

Where you live

The biggest swing: a 10×10 averages ~$80 nationally but ~$219 in Los Angeles. City and demand matter as much as size.

Climate control

Temperature- and humidity-controlled units add roughly 15–30% — often non-negotiable for electronics, wood, or documents.

Fees & promos

Insurance ($10–30/mo), admin fees, and "first month free" promos that expire quietly — plus rent hikes of 5–10% every 6–18 months.

The hidden one

Renting more space than you need. Most people fill half a unit and pay full price for the empty half — month after month.

The cheaper alternative for most people

Endless is by-the-box: we bring boxes to your door, store them in a secure facility, and bring them back when you ask — so you never pay for empty space, a truck, or packing supplies.

1. Boxes to your door — free sturdy boxes, you pack on your own time.
2. We pick them up & store them — free door-to-door pickup into a secure, climate-controlled facility, cataloged in the app.
3. Back whenever you ask — $9.99/box (less if you prepay), first month $1.

Honestly? Not for everyone.

Storing a whole house of furniture — or you're in a low-cost area with a big load? A traditional unit may be cheaper. Endless wins for boxes, seasonal gear, smaller loads, and high-cost cities — where you'd otherwise pay for a half-empty unit.

Storage cost FAQ

How much does a storage unit cost per month? +

The national average is about $89/month across all sizes (SpareFoot, 2026). A 5×5 averages ~$35; a 10×10 ~$80 — but city prices swing 2–3× (a 10×10 is ~$219 in Los Angeles).

How much is a 10×10 storage unit? +

What's the cheapest way to store your stuff? +

If you're storing boxes and seasonal items (not a full house of furniture), paying per box beats renting a whole unit you only half-fill — especially in expensive cities, and once you add the truck, materials, and insurance a unit really costs.

Is Endless cheaper than Extra Space, CubeSmart, or PODS? +

For box-storable goods it usually is on total cost — you pay per box ($9.99, first month $1) instead of for a whole unit you partly fill, and you skip the truck rental, packing materials, and insurance. Use the calculator above for your ZIP.
