Is a Storage Unit Worth It? Calculator
Storage feels cheap month to month and expensive in total: $150 a month is $1,800 a year, quietly, on auto-pay — often more than it would cost to simply re-buy what's inside. Enter your rent, how long you've had the unit, and what re-buying would honestly cost. You'll see the month the rent overtakes the stuff, and what each path costs from here.

Your unit
Use the number on your actual bill. Many facilities require insurance ($10–$25/mo) and add admin fees — they count exactly like rent.
How long
Enter 0 months stored if you're deciding before renting, and 0 more months if you're emptying it now. Be honest with the second number — units rented "for a few months" routinely run for years.
What's actually inside
The first number is the one that matters, so be strict: walk the unit in your head and add up only the things you would genuinely go out and buy again if it all vanished tomorrow. For most people that's a fraction of what's stored — and used furniture, appliances, and kids' gear cost far less to replace than they did new. The second is a realistic "sell it all this month" figure at used-market prices; leave it blank if selling isn't on your radar.

Assumptions & FAQ
Why does storage rent sneak up on people?
Because every part of it is designed to be forgettable: a small monthly charge, on auto-pay, with no end date. $150 a month never feels like a decision — but it's $1,800 a year and $5,400 over three years, paid to hold goods that are usually worth less every year. Most people never multiply it out, which is why the crossover month above surprises almost everyone who checks.
When is a storage unit genuinely worth it?
Often. Short, defined transitions are exactly what storage is for: between homes, mid-renovation, a deployment or long trip, an estate being settled, seasonal business stock, or records you're required to keep. High-value contents over a short horizon beat re-buying easily — and this calculator will tell you so. The math only turns against storage when a temporary unit quietly becomes a permanent one.
What are my options if the numbers say sell?
Neutrally: local marketplaces and consignment get the best prices but take time and effort; donation is fast and may be tax-deductible where you live; passing things to family or friends costs nothing. Used prices are almost always lower than people hope — that's why this tool asks for an honest resale figure rather than assuming one. We have no relationship with any selling, donation, or storage service.
Why does the verdict ignore what I've already paid?
Because that money is spent whichever way you decide — economists call it a sunk cost. The only question you can still act on is the one the verdict answers: is the rent ahead of you worth more or less than what selling now and re-buying later would net? The paid-so-far and crossover figures are shown for clarity, not to guilt you about the past.
What about sentimental or irreplaceable things?
They're a legitimate reason to keep a unit that no dollar figure can capture. Photo albums, heirlooms, a late parent's belongings — these have no re-buy price, and "the math says sell" simply doesn't apply to them. This page's job is to show you what the storage costs, so whatever you decide, you decide it with clear numbers rather than by default.
Are these numbers estimates?
Yes. Everything is calculated from the figures you type — nothing is looked up. The projection assumes your rent stays flat, and real storage rents typically rise over time, so the projected total is, if anything, an underestimate. Replacement and resale values are your best guesses. Treat the result as a planning estimate, not financial advice.
Do you earn anything if I sell, donate, or rent storage?
No. This page currently has no affiliate relationship with any storage company, marketplace, or charity, and contains no tracking links to any of them. If that ever changes, it will be disclosed here.
Do my numbers get uploaded?
No. The page is fully client-side; everything is calculated in your browser.
