How this is calculated
- contribution per occupied bed = rent − variable cost
- break-even beds = (fixed costs − other income) ÷ contribution
- break-even occupancy = break-even beds ÷ total beds
- profit(occ) = beds × occ × contribution + other income − fixed costs
- occupancy for margin m = (fixed − other×(1−m)) ÷ (beds × (rent×(1−m) − variable))
- cash to ramp = Σ negative monthly profits, occupancy rising linearly to target
Note the design choice: your rent is an input, and fixed costs are separated from per-resident variable costs. Calculators that skip this cannot react to your numbers — change the costs and the occupancy answer stays the same, which is how operators get false comfort. If you think a formula here is wrong, tell us — we'll fix it publicly.
How break-even occupancy actually works
Every occupied bed contributes its rent minus the costs that only exist because that resident does — the marginal utilities, cleaning consumables, payment fees. That difference is the contribution margin. Your fixed costs (property lease, staffing, insurance, software, marketing) must be covered by the sum of those contributions. Break-even is simply the number of contributing beds that covers the fixed block, expressed as a share of your total beds.
This is why the two cost types must be separated. Treat everything as fixed and you overstate break-even; ignore variable costs and you understate it — and either error compounds when you use the number to set prices, negotiate a lease, or size a launch budget.
A warning about break-even calculators
Before building this one, we tested what already ranks. The most visible coliving break-even calculator on the web does not ask for your rent at all — it derives a price from your costs and a margin slider, which makes the occupancy answer a fixed function of the slider: change your costs tenfold and the break-even percentage doesn't move. A tool that cannot react to your inputs is not a calculator; it is a reassurance machine. Ours takes your actual price and your actual cost structure, and if the configuration cannot break even, it says so plainly.
Five break-even mistakes coliving operators make
- Using headline rent instead of net effective rent. If you routinely give a free week or a move-in discount, your real rent per bed is lower — use that number.
- Forgetting the ramp. Breaking even at 75% is meaningless in month two if you open at 40%. The cash-to-ramp figure above is part of the same calculation.
- No maintenance reserve in fixed costs. Shared houses consume appliances and furniture on a schedule. Budget the reserve monthly or meet it as an emergency.
- Confusing break-even with target. Break-even is a floor, not a goal — price and plan so your expected occupancy sits comfortably above it (we look for a double-digit cushion).
- Recomputing never. Costs drift, prices change, leases renew. Re-run the number quarterly and after any lease or staffing change — it takes a minute with a shareable link.
Frequently Asked Questions
What is break-even occupancy in coliving?+
The occupancy level at which monthly revenue exactly covers monthly costs — below it every month burns cash, above it every additional occupied bed is profit. It is calculated from contribution margin: fixed costs divided by what each occupied bed contributes (rent minus per-resident variable cost), divided by total beds.
What's a healthy break-even occupancy for a coliving space?+
The lower the better, but the number that matters is your cushion: the gap between realistic expected occupancy and break-even. A house that breaks even at 65% and runs at 90% has a 25-point cushion and can absorb a bad quarter; one breaking even at 88% is one soft month from losing money. If your break-even lands above roughly 85%, treat it as a pricing or cost-structure warning, not an occupancy target.
Why do I need to separate fixed and variable costs?+
Because they behave differently as the house fills. Rent, staffing and insurance stay the same whether 5 or 20 rooms are occupied; extra utilities, cleaning consumables and payment fees scale with residents. A calculator that lumps them together cannot respond correctly to your inputs — and gives the same break-even answer no matter what your costs are, which is exactly the failure mode we built this tool to avoid.
What variable cost per occupied bed should I assume?+
Track your own for two months if you can — it is typically the marginal utilities (heating, water, electricity per person), cleaning consumables, laundry if included, and payment processing on the rent. For a UK shared house a reasonable starting assumption is in the tens of pounds per occupied bed per month, not hundreds; if your figure approaches your rent, the business model itself needs attention before any calculator can help.
How much cash do I need to survive the ramp-up period?+
New coliving spaces rarely open full: occupancy climbs over several months while fixed costs run from day one. The calculator sums your projected losses from opening occupancy to stabilised occupancy — that cumulative figure, plus a buffer for surprises, is the working capital the launch actually requires. Underestimating it is one of the most common reasons otherwise-sound coliving projects fail in year one.
Break-even higher than you'd like?
The levers are pricing, cost structure and occupancy marketing — all three are our day job across 15+ coliving brands.
