Break-even occupancy: 82.73%Estimate

A percentage expense row is resolved at the vacancy you entered, so a genuinely lower occupancy would also reduce that fee slightly. The figure is not iterated to a fixed point.

How to use the Break-Even Occupancy Calculator

  1. Enter the rent and the vacancy you expect.
  2. List the annual operating costs, leaving the mortgage out.
  3. Enter the loan amount, rate and term.

The occupancy a property has to hold

break-even occupancy = (operating expenses + annual debt service) ÷ gross scheduled rent

It converts a deal into a single question about resilience: how much of the rent roll can disappear before the property stops paying for itself.

A property needing 83% occupancy has meaningful room at a 5% vacancy assumption. One needing 96% is relying on almost everything going right, and a single extended void will cost the owner money regardless of how healthy the cash flow looks in a good year.

Headroom, not a verdict

The page reports the gap between the occupancy you expect and the occupancy you need. That gap is the useful number, and what counts as enough of it depends on the property, the market and how long a unit typically sits empty — none of which a calculator can see. No threshold is suggested here.

Where leverage shows up

Operating costs and debt service enter the numerator together, but they behave differently. Operating costs are largely a property of the building. Debt service is a choice. Two buyers of the same building at the same price can face very different break-even occupancy, and the one who borrowed more has less margin for a bad year.

With your numbers

  1. Operating costs and debt service = $29,288.08
  2. Break-even occupancy = $29,288.08 ÷ $35,400.00 = 82.73%
  3. At the 5% vacancy you entered, headroom is 12.27%

Quick reference

Common questions about the Break-Even Occupancy Calculator

What does break-even occupancy actually mean?
The share of scheduled rent the property must collect to pay its operating costs and its mortgage, with nothing left over. Above it the property is self-supporting; below it the shortfall comes from elsewhere.
Why does my vacancy assumption appear here?
For two reasons. It sets the headroom between the occupancy you expect and the occupancy you need, and it fixes the income that any percentage expense row is charged against.
Is the percentage expense row exactly right at the break-even point?
No, and the page says so rather than hiding it. A management fee charged on collected income would itself be slightly lower at a genuinely lower occupancy. The figure is resolved at the vacancy you entered and is not iterated to a fixed point, which leaves it marginally conservative.
How does more borrowing change it?
It raises it. Debt service is in the numerator, so a larger loan or a shorter term pushes the occupancy the property needs closer to full.
Does it include a reserve for capital items?
Only if you entered one as an expense row. The calculation covers the costs you listed and the loan, nothing more.
