Every home has zombie items: neither used nor discarded. They seem free — but the moment you put them in self storage, each month of indecision has an exact price. We did the math.
There's a category of object nobody names but everybody owns: the zombie item. Not alive (you haven't used it in months) nor dead (you never had the courage to throw it out). It lingers in a grey zone — usually a box at the back of a closet, or worse, a self storage unit.
At home, the zombie item seems free. Its cost is hidden in the square footage you already pay for. But the moment you put it in self storage, the cost becomes a number. And the number stings.
Say you store an old TV (worth ~$80 secondhand) in a unit. That unit costs, on average, $12 per m³ per month. The TV takes ~0.2 m³ — so $2.40/month just for it.
Sounds trivial. But you don't store just the TV. You store the TV + the bike nobody rides + the 4 boxes of books you'll never reread + the table that doesn't fit the new place. Suddenly it's 4 m³ of zombie items = $48/month = $576 a year to store things that together might be worth $300.
You're paying nearly double the items' value just to postpone deciding about them.
It's not stupidity — it's behavioural economics. Humans feel the pain of discarding ('loss aversion') far more strongly than the pleasure of saving. Tossing the TV hurts now; the $2.40/month hurts diffusely, spread out, almost invisible.
Self storage accidentally becomes an expensive procrastination machine: it removes the decision trigger (you don't see the items) while keeping the cost running silently.
One simple rule cuts the knot: if storing an item for 12 months costs more than buying it again, let it go.
A $80 TV costing $29/year to store? Maybe worth it — rebuying costs more. But the same TV stored for 3 years costs $86, more than it's worth. Then it makes no sense.
The calculation shifts with storage time. That's why we built a tool that runs the numbers item by item.
Not every stored item is a zombie. It makes total sense to keep when: the item has real value (good furniture, working appliances), you have defined future use (moving to a new place in 3 months), or sentimental value outweighs any math (and it's fine to own that consciously).
The problem isn't storing. It's storing without deciding — letting indecision become an automatic monthly subscription.
Before renting a unit, run your items through the [Keep or Let Go tool](/en/keep-or-let-go/). In 2 minutes you see, item by item, what's worth keeping and what's just costing money.
If the conclusion is to keep — great, [compare operators in the directory](/en/directory/) or [ask our concierge](/en/contact/). If it's to let go, you just saved more than you thought.
