How Do You Calculate Break-Even Occupancy for a Commercial Property? (2026)

Break-even occupancy = (operating expenses + debt service) / potential gross income. A worked example, the variants lenders use, and which tool fits the calculation.

Break-even occupancy is the share of potential gross income a property must collect to pay its operating expenses and its debt service: (operating expenses + debt service) / potential gross income. A spreadsheet handles the arithmetic; the hard part is the inputs, which is where an underwriting model built from the rent roll, T-12 and loan terms (Titleman builds one in live Excel) or lease-by-lease cash flow software for long holds earns its place.

Updated 19 October 2026. Published by Titleman, which makes one of the tools compared.

The formula

Break-even occupancy = (operating expenses + annual debt service) / potential gross income

  • Potential gross income (PGI): rent at 100 percent occupancy plus other income you count. Say whether rents are in-place or market.
  • Operating expenses: from the T-12, normalized: taxes after a sale, insurance at the new quote, a market management fee.
  • Debt service: a full year of principal and interest on the proposed loan. Some lenders add replacement reserves to the top line; state whether you did.

The gap between actual occupancy and the break-even is the cushion.

A worked example

For example, a 48-unit building with illustrative figures that describe no real property:

LineAmount (dollars a year)
PGI: 48 units x 2,100 x 121,209,600
Operating expenses (normalized)470,000
Debt service on the proposed loan520,000
Expenses + debt service990,000
Break-even occupancy990,000 / 1,209,600 = 81.8%

If the building runs at 94 percent, the cushion is about 12 points. Now raise expenses 10 percent, to 517,000: the break-even moves to 85.7 percent and the cushion shrinks to about 8 points.

Variants to name in the memo

  • Operating break-even: expenses only, without debt. Useful for an all-cash buyer.
  • EGI basis: some analysts divide by effective gross income after concessions and credit loss, which gives a higher ratio.
  • With reserves: add replacement reserves, or for office and retail, leasing costs.

Where Titleman fits

Titleman's underwriting reads the rent roll, T-12 and OM for an address and returns a memo and a live Excel model with DSCR, debt yield and sensitivity grids; break-even occupancy is a formula you can ask for in the brief. The median run on production in the 30 days to 18 October 2026 took about 58 minutes. Every input shows its source; a missing figure is named, not filled.

FAQ

What is a good break-even occupancy?

There is no single number. Lenders compare it with the property's occupancy history and market vacancy; a ratio close to current occupancy leaves little room.

Does break-even occupancy include capital expenditures?

The basic formula does not. Many lenders add replacement reserves, and on office or retail, leasing costs.

How is it different from DSCR?

DSCR divides net operating income by debt service. Break-even occupancy asks how full the property must be to pay expenses and debt. Both use the same inputs, so a change in one shows up in the other.

Can Titleman calculate break-even occupancy?

Yes, inside an underwriting run, as a formula in the live Excel model built from the rent roll, T-12 and the loan terms in the brief. It does not give a buy or lend verdict.
