Moving storage cost: $80 to $400 per month between homes
Storage between homes is one of the most common reasons people rent self storage, and the cost depends almost entirely on duration. A 30-day bridge is essentially free with the universal first-month promotion. A 90-day move sits at $220 to $560. A 6-month renovation runs $440 to $1,200. Below: duration math, portable container alternatives (PODS, U-Box, 1-800-PACK-RAT), insurance overlap with movers and homeowners policies.
What moving storage actually costs by duration
Duration is the dominant variable in moving storage cost, more so than unit size or city. The reason is the first-month-free promotion. Every major chain (Public Storage, Extra Space, CubeSmart, U-Haul) and most independents offer first-month-free as a standard new-customer promotion. For a 30-day move-bridge, this makes the rent itself free; you pay only admin fee ($15 to $30), lock ($10 to $15), and insurance ($10 to $20 prorated). Total $35 to $65 for a month-long stash of a full apartment's contents.
The math changes once you cross 30 days. Months 2 and 3 are at the asking rate, which is the headline price you see advertised. Months 4 through 6 typically include a post-promo rate increase of 15 to 25 percent (well-documented in Public Storage's 2024 10-K and applied across the chain segment). For a 90-day move, expect roughly 2.5 months of rent at asking plus admin and insurance, totalling $220 to $560 for a 10x10. For a 6-month renovation or sale gap, total $700 to $1,400.
For moves over 6 months, the cost compounds. Plan to call and negotiate the rate increase, plan to consider switching to U-Haul (the only chain with a 12-month rate lock), and plan to budget for at least one annual increase of 5 to 10 percent. Long-term storage of more than a year favours U-Haul or independent operators with stable pricing over PSA, EXR, and CubeSmart with their disciplined rate-management.
Cost by storage duration
10x10 storage cost / by duration / 2026
| Duration | Total cost | Best for |
|---|---|---|
| 1 month (transitional) | $80 to $180 | Closing-day gap, painting/cleaning gap, brief overlap |
| 2 to 3 months | $220 to $560 | Cross-country move, sale-purchase timing gap |
| 4 to 6 months | $440 to $1,200 | Renovation, downsize-then-buy, deployment |
| 7 to 12 months | $700 to $2,400 | Long renovation, divorce, executor sales |
Portable container vs traditional self storage
For moves where the storage is paired with transportation needs, portable container services compete with traditional self storage. The container model: company delivers an empty container to your driveway, you load it, they pick it up and store it (or transport it to a new address), and deliver it again at the destination. The decision math depends on duration and whether you also need transport.
Portable container compare / 2026
| Provider | Monthly storage | Delivery fee (each) |
|---|---|---|
| PODS | $170 to $290 | $80 to $250 |
| U-Haul U-Box | $80 to $150 | $60 to $200 |
| 1-800-PACK-RAT | $140 to $260 | $70 to $230 |
| Traditional 10x10 chain | $100 to $200 | Truck rental separate |
For storage-only with your own truck access, traditional self storage at $100 to $200 per month for a 10x10 is the cheapest option. For storage-plus-transport (load at home A, ship to home B), a portable container saves the cost of renting a moving truck twice but adds container delivery fees. For a typical 60-day cross-country move, a U-Box or PODS bundle often beats traditional storage plus separate moving truck rentals by $200 to $500.
Insurance overlap: don't double-pay
Three insurance products can cover moving storage: your existing renters or homeowners policy (off-premises personal property coverage), your moving company's released-value or full-value protection, and the storage facility's insurance. They overlap, and most renters end up paying for at least two when one would suffice.
Renters / homeowners off-premises coverage. Most policies include 10 percent of the contents limit for off-premises personal property. A $50,000 contents policy typically covers $5,000 in storage. For high-value inventories, this may be insufficient and you can buy supplemental endorsement. Call your insurer and ask. The cost is usually $0 to $30 per year for an endorsement, well below the $120 to $240 per year of facility-offered insurance.
Mover's liability. Required by federal law for interstate moves, optional for local moves. Released value (the default) pays $0.60 per pound per item, which is essentially zero coverage for furniture and electronics. Full-value protection adds $0.50 to $1.00 per $100 of declared value, typically $50 to $200 for a typical 1-bedroom move. The mover's coverage applies during the actual move, not during storage.
Facility-offered insurance. $10 to $25 per month at most chain facilities, required at PSA, EXR, and CubeSmart but optional at U-Haul. Coverage typically caps at $2,000 to $25,000 depending on tier. The cheapest tier is genuinely cheap protection but limited; the higher tiers are expensive relative to comparable supplemental endorsements on your existing policy.
The optimal stack for most moves: keep mover's released value (default), use existing renters or homeowners off-premises coverage with a supplemental endorsement if needed, decline facility insurance with proof-of-coverage paperwork. Total annual cost typically $30 to $60 versus $120 to $300 with facility insurance.
