Break-Even Analysis
Minimum 87.06% occupancy required to avoid operating deficit
Break-even ratio is 87.06%. Minor vacancy or rent concessions will cause negative cash flow. Consider higher down payment to lower debt service.
What Is the Break-Even Ratio and Why It Matters
The Break-Even Ratio (BER) is a fundamental risk evaluation metric used by commercial real estate lenders and underwriting teams to gauge a property's vulnerability to vacancy and negative cash flow. BER shows the exact percentage of occupancy (or gross revenue) required to pay all operating expenses and annual mortgage debt service combined. A lower BER indicates a larger safety margin, meaning the property can weather economic downturns, tenant defaults, or rising expenses. Commercial lenders typically require a BER below 80% to 85%.
The Formulas
Break-Even Ratio (%) = ( Operating Expenses + Annual Debt Service ) / Effective Gross Income (EGI) × 100%
Max Allowable Vacancy (%) = 100% − Break-Even RatioA Real Office Property Break-Even Example ($220k EGI)
Frequently Asked Questions
What is a good Break-Even Ratio for commercial lenders?
Most commercial lenders prefer a Break-Even Ratio under 80%. A BER below 80% signifies a robust financial cushion, making loan approval easier and interest terms more favorable.
How does Break-Even Ratio differ from DSCR?
While DSCR measures net operating income against debt service (NOI / Debt Service), BER measures total fixed obligations (Expenses + Debt Service) against gross income (EGI). BER explicitly reveals the minimum required occupancy percentage to break even.
How can an investor lower a property's Break-Even Ratio?
Investors can lower BER by reducing debt service (larger down payment or lower interest rate), auditing and curbing operating expenses, or increasing gross revenues through rent adjustments or amenity fees.
