Self-Storage vs Moving Cost Calculator
Decide whether to pay monthly for a storage unit or just move (or replace) your belongings — and find the month where storage stops paying off.
How it works
Storage total = move-in fee + monthly rent × months · Break-even months = (move cost − move-in fee) ÷ monthly rent
Storage looks cheap month to month, but the meter never stops — a modest monthly rent quietly compounds into a large annual number. Comparing the running storage total against the one-time cost to move (or simply re-buy) the items shows when the recurring bill overtakes the one-off expense. The break-even month is the tipping point: keep paying past it and you would have been better off just moving the stuff.
Worked example
A $120/month unit with a $30 move-in fee costs $30 + $120 × 12 = $1,470 over a year. If moving those items instead costs $900, moving is $570 cheaper, and storage break-even is (900 − 30) ÷ 120 ≈ 7.3 months.
Frequently asked questions
When does a storage unit stop making sense?
Once your running storage total passes the cost to move or replace the items — the break-even month in this calculator. Storing low-value belongings for a year often costs more than the belongings are worth, which is why decluttering before you rent a unit usually beats renting a bigger one.
What counts as the "move cost" here?
Use whichever alternative you would actually choose: hiring movers or a truck to take the items with you, or the realistic cost to re-buy the same items later if you let them go. That is the true thing storage is competing against.
Should I include the move-in fee?
Yes — many facilities charge a first-month promotion offset by an admin or move-in fee, plus a required lock or insurance. Folding those one-time costs into the storage total keeps the comparison fair.
