Your stuff has a secret budget. This calculator finds it.
We built one tool. One job.
It asks: what is your clutter actually costing you? Not in feelings. In money, hours, and square footage you already pay for.
What it measures (and nothing else)
Four costs run at the same time. The calculator separates them so you can see which one is eating you alive.
Space rent. You pay for every square foot of your home. The box in the corner, the bike you haven’t touched since 2019, the stack of “someday” projects — they all occupy real estate. The calculator multiplies your clutter footprint by your actual rent or mortgage per square foot. That number is what your landlord or bank charges you monthly for storage you never asked for.
Value decay. Things lose value while they sit. Electronics bleed fastest — roughly 4% of their remaining worth every month. Furniture, slower. Clothes, somewhere in between. The calculator applies category-specific depreciation curves to what you paid and how long it’s been idle. The result is what you’re losing right now by not selling.
Focus tax. This one surprises almost everyone. Every unresolved object — the drawer you don’t open, the bag you step over — occupies a small slice of your working memory, continuously, even when you’re not consciously thinking about it. The calculator estimates the potential productivity cost by converting unresolved decisions into equivalent work hours, then multiplying by your hourly rate. For many people, this line ends up larger than space and depreciation combined.
Insurance drag. A quiet line item. Your renter’s or homeowner’s policy covers everything you own — including things you no longer use. The calculator applies a conservative 0.5% annual rate, typical for US renter’s or homeowner’s policies, to the estimated value of your stored items. Your actual rate varies by policy and location, so treat this line as a directional indicator rather than a precise cost. Small per month. Over years, it’s real.
Freedom Score — what the number actually means
The score weighs your space cost, mental load, value drain, and insurance drag together. A score above 80 means your home is working for you, not the other way around — typical of people who actively declutter once or twice a year. Below 40 means your storage is running your finances more than you realize, usually a sign of a large unmanaged storage space. Most households with kids and a few years of accumulated items land somewhere in the 55–72 range — comfortable, not alarming, but not free either. Below 20 — Storage Prison — is rare, but common among anyone who hasn’t touched a garage or spare room in several years. The score isn’t a personality judgment. It’s math. It updates based on what you enter, not how you feel about it.
The heatmap — which room costs the most
After you enter what’s in each room, the calculator builds a color-coded floor plan. Cold zones cost almost nothing. Hot zones are bleeding rent. Most people discover the garage or spare closet is their most expensive square footage — more than the kitchen they actually use every day.
Biggest hidden expense — the one line that dominates
The calculator scans all four cost categories and calls out the single biggest drain on your finances. One line always leads. Sometimes it’s focus tax. Sometimes it’s value decay from electronics sitting in a drawer. The calculator shows the winner with its monthly and annual figure, plus a short explanation of why it’s hitting so hard. Below that, all four costs appear as a relative bar chart — so you can see at a glance how the others compare. This section exists because people tend to fixate on the total and miss the leverage point. Knowing your biggest leak tells you exactly where to start.
Future regret predictor
The calculator doesn’t just show today’s cost. It projects forward. Based on the depreciation rate of each category you entered, it shows what your items will be worth in 6 months and 2 years if you keep them. The gap between “sell now” and “sell later” is what indecision costs.
Freedom timeline — what happens if you do nothing
Two lines. One red, one green. The red line shows your cumulative cost over 24 months if you change nothing — every box stays, every unused item keeps depreciating. The green dashed line estimates what happens if you declutter now: space cost drops significantly, focus tax roughly halves, and insurance drag shrinks. The gap between the two lines is your potential two-year savings. It’s not a guarantee. It’s a projection based on what you entered. But the shape of the graph tends to make the decision obvious.
Action plan that reads your reason
Everyone keeps clutter for a different reason. The calculator asks you to pick yours: “It’ll come in handy” / “It feels wrong to toss” / “I just haven’t gotten to it.” Same math, different plan. If you’re a “useful someday” type, the plan pushes selling high-depreciation items first. If guilt is your blocker, it suggests photographing sentimental objects and letting the physical version go. The advice shifts. The numbers don’t.
Note: psychotype also affects how your focus tax is estimated — guilt tends to generate more persistent cognitive load than inertia, so the “it feels wrong” path weights mental cost about 20% higher than the “haven’t gotten to it” path.
No accounts. No storage. No upsells.
The calculator runs entirely in your browser. It doesn’t save your data. It doesn’t ask for your name. You close the tab, it’s gone — just like the clutter it measures.
Why this exists
Most decluttering advice is vague. “Does it spark joy?” is a question, not a budget line. We wanted something sharper. A tool that treats your home like an asset and your stuff like inventory — because that’s what it is, whether you think about it or not. One calculator. Four hidden costs. One number that might finally make you list that old laptop.
