Break-Even Occupancy Explained: How Much Vacancy a Georgia Commercial Property Can Survive

Every income property has a line. Above it, the building pays you. Below it, you pay the building. Most buyers never compute where that line is before they close. By Túy “Dewey” Luong, CCIM — Founding Broker, SERHANT. Atlanta · 318 closed sales / $281.2M career volume · 678-707-2498

Break-even occupancy is the lender's stress test stated in plain terms: the occupancy at which collected income exactly covers operating expenses plus the mortgage. It sits next to DSCR and debt yield in every serious underwriting, but it answers the question owners actually ask — how much vacancy can this building survive? This page shows the formula, works a complete example you can check line by line, converts it to break-even rent, and covers the traps that make the published number look safer than it is.

The formula

• Break-even occupancy = (operating expenses + debt service) ÷ potential gross income. Potential gross income is every dollar the property would collect at 100% occupancy — scheduled rent plus other income. The result is a percentage: occupy at or above it and the property covers its bills and its loan.
• The cushion is the complement: 100% minus the break-even is the vacancy the property can absorb. A 72.4% break-even means a 27.6-point cushion — and the cushion, not the ratio, is the number to compare against your market's real vacancy.
• Break-even rent = (operating expenses + debt service) ÷ rentable square feet. The same line expressed as a rent, for leasing and renewal decisions.
• It is a collected-income test, not a leased-percentage test: the math runs on money actually received. A signed tenant who stops paying counts as vacancy for this purpose, whatever the rent roll says.

Worked example. The numbers below are made up and rounded to teach the mechanics. This is not a real property.

• A made-up Gwinnett retail center: 12,000 rentable square feet at a $20.00 average asking rent — $240,000 of scheduled rent at full occupancy, plus $6,000 of other income, for potential gross income of $246,000.
• Operating expenses are $58,000 a year (taxes, insurance, CAM, management). Debt service is $120,000 a year. Together: $178,000 that must be collected before the owner sees a dollar.
• Break-even occupancy: $178,000 ÷ $246,000 = about 72.4%. The center can run roughly 27.6% vacant and still cover expenses and the loan. At full occupancy the same figures give NOI of $188,000 and a DSCR of about 1.57x — comfortable coverage and a wide vacancy cushion describe the same deal from two angles.
• Break-even rent: $178,000 ÷ 12,000 SF = about $14.83 per square foot, against the $20.00 asking rent. In a renewal negotiation, that is the floor the landlord's economics are built on — concessions that push effective rent toward it are not generosity, they are erosion.
• What a point is worth: each occupancy point on this building is 1% of $246,000 — $2,460 a year of cash flow. At 85% occupancy the center collects $209,100, pays the $178,000, and cash-flows about $31,100. At 72.4% it cash-flows zero. The distance between those two outcomes is about thirteen points of occupancy.
• Sensitivity — expenses move the line: raise operating expenses 10% (to $63,800 — one insurance renewal can do it) and the break-even climbs to about 74.7%. Nothing about the building's rent changed; the cushion shrank anyway. Re-run this number every budget cycle, not just at purchase.

How lenders and owners read the number differently

• Lenders compare the break-even to the submarket's vacancy history and to the tenant roll: ten small suites diversify the risk that one departure crosses the line; one anchor at 40% of the rent makes the percentage almost meaningless without a lease-expiry view.
• Owners use it as an early-warning gauge: when actual occupancy drifts within a few points of the break-even, the property has no shock absorber left for a tax reassessment, an insurance spike, or a roof — the items due diligence is supposed to surface before closing.
• Buyers use it to size the loan, not just the price: a smaller loan lowers debt service, which lowers the break-even. On the worked example, the break-even is as much a financing decision as a property fact — the same trade-off the SBA 504 structure exploits for owner-occupants.

The traps inside a break-even number

• Other income counted at full tide: percentage rent, reimbursements and fees shrink when occupancy falls — but the standard formula counts them at 100%. Excluding the $6,000 of other income in the worked example raises the break-even from 72.4% to 74.2%. Ask which version you are being shown.
• Reserves and leasing costs left out: a break-even computed without replacement reserves, tenant improvements and leasing commissions is an operating break-even, not a cash break-even. The honest line is higher.
• Fixed costs do not take a vacancy holiday: taxes, insurance, debt service and most CAM continue at 60% occupancy exactly as at 100%. The cushion math assumes income falls linearly; costs do not.
• Break-even above 85%: at that level a single mid-size departure, a reassessment, or one bad quarter puts the owner writing checks. Deals quoted there need either a price that pays for the risk or a loan small enough to pull the line down.

Cho nhà đầu tư và chủ doanh nghiệp người Việt

Nhiều nhà đầu tư người Việt tại Metro Atlanta và Gwinnett nhìn cap rate và DSCR nhưng ít khi tính điểm hòa vốn theo mức lấp đầy — con số cho biết tòa nhà có thể trống bao nhiêu mà vẫn tự trả được chi phí và khoản vay. Trong ví dụ trên, trung tâm bán lẻ giả định ở Gwinnett có điểm hòa vốn khoảng 72,4%: trống gần 28% vẫn an toàn, và mỗi điểm phần trăm lấp đầy trị giá khoảng $2,460 tiền mặt mỗi năm. Tiền thuê hòa vốn là khoảng $14,83/SF so với giá chào thuê $20,00/SF — con số chủ nhà cần biết trước khi nhượng bộ trong đàm phán gia hạn.

Ba điểm cần kiểm tra khi ai đó đưa cho bạn con số này: thu nhập phụ có đang được tính ở mức lấp đầy tối đa hay không (nếu loại ra, điểm hòa vốn trong ví dụ tăng lên 74,2%), chi phí dự phòng và chi phí môi giới thuê đã được tính chưa, và chi phí vận hành tăng 10% sẽ đẩy đường hòa vốn lên bao nhiêu (trong ví dụ: lên khoảng 74,7%).

Frequently asked questions

What is break-even occupancy, in plain English?

Break-even occupancy is the occupancy level at which a property's collected income exactly covers its operating expenses plus its loan payments — no profit, no loss. You add annual operating expenses to annual debt service and divide by potential gross income at full occupancy. In the worked example on this page, $58,000 of expenses plus $120,000 of debt service, divided by $246,000 of potential gross income, gives a break-even of about 72.4%: the building can sit roughly 27.6% empty and still pay every bill and the mortgage.

What is break-even rent, and how is it different?

Break-even rent is the same test stated as a rent instead of a percentage: operating expenses plus debt service, divided by the rentable square feet. In the worked example, $178,000 divided by 12,000 square feet is about $14.83 per square foot — against a $20.00 asking rent. It answers a leasing question (how far can rent fall before the property bleeds?) where break-even occupancy answers an operations question (how much vacancy can the property absorb?). A property can fail one test and pass the other, so run both.

What break-even occupancy do lenders consider safe?

There is no universal cutoff, but the logic is consistent: lenders compare your break-even against the vacancy your market actually experiences. A break-even in the low 70s in a Gwinnett retail corridor that runs 5 to 8% vacant leaves a wide cushion. A break-even above 85% means one mid-size tenant leaving can push the property cash-flow negative, and lenders price or decline that risk. Judge the number against the submarket's real vacancy history and the tenant mix — a 78% break-even on a center with ten small tenants is a different risk from 78% on a two-tenant building.

What are the traps in a break-even calculation?

Four. First, other income — percentage rent, CAM reimbursements, vending, parking — is often counted at full occupancy even though it shrinks when tenants leave; excluding it in the worked example raises the break-even from 72.4% to 74.2%. Second, replacement reserves and leasing costs are frequently left out of expenses, which understates the true line. Third, most operating expenses do not fall when a suite goes dark — taxes, insurance and debt service are fixed — so the cushion is thinner than the percentage suggests. Fourth, break-even is computed on collected income, not leased percentage: a 'leased' tenant who stops paying moves you below the line while the rent roll still looks full.

Tỷ lệ lấp đầy hòa vốn (break-even occupancy) là gì?

Đây là mức lấp đầy mà tại đó thu nhập thu được của tòa nhà vừa đủ trả chi phí vận hành và tiền trả nợ vay — không lãi, không lỗ. Công thức: (chi phí vận hành + tiền trả nợ) chia cho tổng thu nhập tiềm năng khi lấp đầy 100%. Trong ví dụ trên trang này, tòa nhà bán lẻ giả định ở Gwinnett có điểm hòa vốn khoảng 72,4%, nghĩa là có thể trống gần 28% mà vẫn trả đủ mọi chi phí và khoản vay; tiền thuê hòa vốn là khoảng $14,83/SF so với giá chào thuê $20,00/SF. Khi xem một thương vụ, hãy kiểm tra: thu nhập phụ có đang được tính ở mức lấp đầy tối đa không, chi phí dự phòng sửa chữa đã được tính chưa, và điểm hòa vốn có quá gần mức trống thực tế của khu vực không.
