Real Estate Break-Even Calculator

The break-even ratio (BER) in real estate is the occupancy rate at which a property's gross rental income exactly covers all operating expenses and debt service. BER = (Operating Expenses + Debt Service) / Gross Potential Rent. A property must maintain an occupancy rate above the BER to generate positive cash flow.

Break-Even Occupancy (%) = (Total Annual Expenses + Annual Debt Service) / Annual Gross Potential Rent x 100. If your total expenses and mortgage payments are $24,000 per year and potential rent is $30,000 per year, break-even occupancy is 80%. Any occupancy above 80% generates positive cash flow.

Lenders use the break-even ratio to assess risk when underwriting investment property loans. A lower break-even ratio means the property needs less occupancy to service its debt, which represents lower risk. Lenders often prefer properties with a break-even ratio below 85%. Above 90% is considered high risk.

Break-even rent is the minimum monthly rent per unit (at full occupancy) needed to cover all expenses and debt service. Break-Even Rent = (Annual Expenses + Annual Debt Service) / (Number of Units x 12). This helps investors determine if the market will support sufficient rent to make a deal work.

Break-even analysis helps investors understand downside risk: how far can occupancy fall before the property stops paying for itself? It also helps set minimum acceptable rent levels. A property with a break-even occupancy of 70% has a much larger margin of safety than one that requires 95% occupancy to break even.
