How to calculate break-even occupancy for a rental property
Break-even occupancy is operating expenses plus loan payments, divided by the rent the building would collect if every unit were rented. If that comes to 85%, the property pays all its bills when 85 of every 100 rent dollars arrive, and any occupancy above that is profit.
The formula
Break-even occupancy = (operating expenses + debt service) divided by gross potential rent. Gross potential rent is every unit's rent for the year, as if all of them were occupied and paid in full.
Example a made-up 10-unit building has gross potential rent of $120,000. Operating expenses are $42,000 and debt service is $60,000. Together those are $102,000. Break-even occupancy is $102,000 divided by $120,000, which is 85%.
In units, 85% of 10 units is 8.5. If the building has fewer than nine units' worth of rent coming in on average, the owner pays the difference from savings.
Getting the three inputs right
- Gross potential rent: use the scheduled rent from your rent roll, twelve months, every unit rented at its current rent.
- Operating expenses: property tax, insurance, repairs and maintenance, utilities you pay, management and admin. Use the last twelve months from your profit and loss, not a guess.
- Debt service: twelve months of principal and interest. Leave out escrow, since tax and insurance are already in operating expenses.
IRS Publication 527 is useful for the cost side. It lists what a landlord can deduct, such as taxes, insurance, repairs and interest, and separately explains depreciation. Depreciation is a tax deduction but not a cash cost, so it stays out of break-even occupancy. Principal repayment is a cash cost but not a tax deduction, so it goes in.
Break-even with reserves
The basic version treats the property as safe once the bills are paid. Roofs and boilers do not read the formula. A stricter version adds a yearly reserve for big repairs and replacements.
Example add a $6,000 yearly reserve to the same building. Costs are now $42,000 plus $60,000 plus $6,000, which is $108,000. Break-even occupancy is $108,000 divided by $120,000, which is 90%.
| Version | Yearly cost covered | Break-even occupancy |
|---|---|---|
| Operating costs and loan | $102,000 | 85% |
| Plus $6,000 reserve | $108,000 | 90% |
Five more points of occupancy sounds small. On ten units it is half a unit, rented all year. For a plan on how much to set aside, see capital reserves per unit.
How to use the number
Compare break-even to the occupancy you actually get. If the building is 95% occupied and break-even is 85%, there is a ten-point cushion. If both are near 90%, one move-out can push the property into the red until the unit is rented.
Use it before you buy, before you refinance, and before you decide on a big expense. A lower break-even means the property can carry a bad quarter. You can lower it by cutting costs, refinancing to a lower payment, or raising rents when the lease allows, as in how much to raise rent fairly.
Remember what occupancy means here. Rent that is billed but never paid does not help, so many owners track economic occupancy, which counts dollars collected rather than units filled.
How DoorKeeping handles it
Ask Claude or ChatGPT through DoorKeeping for the rent roll, the property's profit and loss for the last twelve months, and the delinquency report. Each property has its own books, so the costs are not mixed with another LLC's. Give the assistant your yearly loan payments and it can do the division. DoorKeeping reads your numbers and does not move rent: tenants pay your own bank account.

Questions
- What is break-even occupancy?
- It is the share of your possible rent you must collect to pay operating costs and the loan. Above it the property makes money. Below it you add your own cash.
- Is break-even occupancy the same as break-even ratio?
- Usually yes. Some sources call the same calculation the break-even ratio or default ratio. Check the formula a source uses.
- Should depreciation be in the formula?
- No. Depreciation is a tax deduction, not money you pay out, so it stays out of a cash break-even.
- Should I include reserves?
- It is safer to. Show both versions, with and without reserves, so you see how much room the building has.
