For illustration, not advice. Break-even occupancy = (operating expenses + annual debt service) ÷ gross potential income. It treats every expense as fixed and ignores capital reserves, concessions and the timing of rent; lenders and underwriters may define it differently.
The break-even occupancy formula
Break-even occupancy is the share of a property’s potential income it must collect to pay its operating expenses and its loan. Below it, the owners fund the shortfall.
- Break-even occupancy = (operating expenses + annual debt service) ÷ gross potential income
- Cushion = current occupancy − break-even occupancy (in percentage points)
Gross potential income is everything the property would collect at 100% occupancy and market rent. Operating expenses are the costs that make up NOI — taxes, insurance, utilities, repairs, payroll, management. Annual debt service is twelve months of principal and interest.
A worked example
A property has $1,200,000 of gross potential income, $520,000 of operating expenses and $500,000 of annual debt service. Break-even occupancy is ($520,000 + $500,000) ÷ $1,200,000 = $1,020,000 ÷ $1,200,000 = 85.0%.
The property is 93% occupied today, so the cushion is 93% − 85.0% = 8.0 points. Each point of occupancy is worth $12,000 of income here, so the cushion is about $96,000 a year. Before debt service, the property would break even at $520,000 ÷ $1,200,000 = 43.3% occupancy — the loan accounts for the rest.
| Case | Expenses + debt service | Break-even | Cushion |
|---|---|---|---|
| Base case | $520,000 + $500,000 | 85.0% | 8.0 points |
| Debt service up $60,000 | $520,000 + $560,000 | 90.0% | 3.0 points |
| Expenses up 10% | $572,000 + $500,000 | 89.3% | 3.7 points |
| No loan | $520,000 + $0 | 43.3% | 49.7 points |
Why lenders and investors ask for it
Break-even occupancy turns leverage into a question anyone can picture: how many units can sit empty before the deal needs cash? A floating-rate loan whose payment rises, a tax reassessment or an insurance renewal all push it up. Read it next to DSCR, which measures the same coverage at today’s occupancy — check yours in the DSCR calculator.
Limits of the simple formula
- It treats every expense as fixed. Some costs, such as utilities and turnover, fall when units are empty, so the true break-even is a little lower.
- It assumes income moves with occupancy at market rent. Concessions, bad debt and below-market leases mean a building can be full on paper and still collect less.
- It leaves out capital reserves and planned capital spending, which some lenders add.
From a calculator to a deal
Build the inputs from a clean operating statement first — the NOI calculator turns rent, vacancy and expenses into NOI. In CREAssets the underwriting workbook carries income, expenses and the loan in one model with sensitivities in the header, and the fund-admin workspace tracks debt and covenant tests after closing. See AI underwriting and fund administration.

Break-even occupancy questions
How do you calculate break-even occupancy?
Add operating expenses and annual debt service, then divide by gross potential income — the income at 100% occupancy. $520,000 of expenses plus $500,000 of debt service over $1,200,000 of gross potential income is 85.0%.
What is the occupancy cushion?
Current occupancy minus break-even occupancy, in percentage points. At 93% occupancy and an 85.0% break-even, the cushion is 8.0 points: occupancy can fall that far before the property stops covering its expenses and loan payments.
Is a lower break-even occupancy better?
A lower break-even leaves more room for vacancy, so the property can absorb a weaker market before it needs cash from reserves or owners. It usually comes from less leverage or lower costs; it does not by itself make a deal a good one.
Does break-even occupancy include capital expenditures?
This formula does not. Some lenders and underwriters add replacement reserves or planned capital spending to the numerator, which raises the break-even. Say which definition you used when you quote it.
What is the difference between break-even occupancy and DSCR?
Both test whether income covers costs. DSCR compares NOI with debt service at today’s occupancy; break-even occupancy asks how low occupancy can go before NOI no longer covers the debt. A deal with a high DSCR usually has a low break-even.
