The Break-Even Occupancy Calculator tells you what percentage of the year your rental property needs to be occupied before it covers its fixed monthly costs. Enter your mortgage, taxes, insurance, and other fixed expenses alongside your expected monthly rent to find your break-even occupancy rate and implied vacancy tolerance.
How to use this tool
Enter every fixed monthly cost: your mortgage payment, property tax, insurance, HOA fees if applicable, a maintenance reserve, and your property management fee if you use a manager. Then enter the rent you would charge a tenant at full occupancy.
Leave HOA fees or property management at zero if they do not apply. The tool adds all costs and divides by your expected rent to calculate the occupancy fraction you need to break even.
Compare your break-even occupancy rate against the vacancy rate typical in your local market. If your break-even requires 95% occupancy in a market with 10% average vacancy, the property may not cover its costs in a normal year.
Understanding your results
Total monthly fixed costs is the sum of every expense you entered. This is the amount you pay whether the property is occupied or empty.
Break-even occupancy is the percentage of months the property must be rented — at your stated rent — to cover all fixed costs. A result of 80% means you need the property occupied for at least 9.6 months out of 12 to avoid a cash loss.
Implied break-even vacancy rate is the flip side: the maximum vacancy your property can sustain before it costs you money. If break-even occupancy is 80%, you can afford up to 20% vacancy.
Monthly cash flow at 100% occupancy is how much you keep each month when the property is fully rented, after all fixed costs. A negative figure means the property does not cash flow even when fully occupied.
Legal context
Break-even occupancy is a cash flow planning metric, not a legal standard. However, US regulators and lenders use vacancy thresholds in specific contexts. HUD considers a property financially distressed if vacancy exceeds 10% for more than six months in federally assisted housing programs. Freddie Mac and Fannie Mae underwriting for investment property typically assumes a vacancy factor of 5–10% when calculating debt service coverage.
The US Census Bureau American Housing Survey tracks national and metro-level vacancy rates. As of 2024, the national rental vacancy rate is approximately 6.6% (US Census Bureau Q4 2024). Vacancy rates vary significantly by city: markets like New York and San Francisco historically run below 4%, while Sun Belt metros can exceed 10%.

Frequently asked questions
What is break-even occupancy?
Break-even occupancy is the minimum percentage of time a rental property must be occupied — at your target rent — to cover all fixed ownership costs. If your fixed costs are $2,000 per month and your rent is $2,500, your break-even occupancy is 80%. Any vacancy rate below 20% means the property covers its costs; above 20%, you have a monthly cash shortfall.
What is a good break-even occupancy rate?
A break-even occupancy rate below 85% gives you a reasonable buffer against vacancy in most US markets. If your break-even is above 90%, the property has limited tolerance for vacancy, tenant turnover, or a short rent reduction. Most experienced landlords target properties where break-even occupancy is 80% or lower, which means the property can sustain up to 20% vacancy — roughly two and a half months per year — without a cash loss.
What are average vacancy rates in California?
California rental vacancy rates vary by metro. Los Angeles and San Francisco consistently run below 4%, reflecting strong demand and limited new supply. Inland Empire and Central Valley markets are typically 5–7%. Statewide, California averages around 4–5% vacancy, which is below the national average. In tight markets, landlords can often afford a higher break-even occupancy rate because vacancy periods are short.
What are average vacancy rates in Texas?
Texas vacancy rates have risen in recent years following significant new apartment construction, particularly in Austin and Dallas. Austin vacancy ran above 12% in 2024, compared to a national average of around 6.6%. Houston and San Antonio are typically 8–10%. Dallas-Fort Worth is 9–11%. Texas landlords should model a higher vacancy assumption — at least 8% — when calculating break-even occupancy.
What are average vacancy rates in New York?
New York City has some of the lowest vacancy rates in the US. The 2024 NYC Housing and Vacancy Survey found an overall rental vacancy rate of 1.4%, the lowest since 1968. Outside the city, upstate New York markets run higher — Albany and Buffalo are typically 4–6%. In New York City, break-even occupancy of 95% or higher is manageable given the low probability of extended vacancy.
What are average vacancy rates in Florida?
Florida vacancy rates vary by market. Miami and Fort Lauderdale run 4–6%, driven by strong demand and in-migration. Orlando and Tampa are typically 6–8%. Jacksonville runs slightly higher at 8–9%. The statewide average is around 7%, close to the national average. Florida landlords should plan for seasonal fluctuation — some markets see higher vacancy in summer months when snowbird tenants depart.
How does an HOA fee affect break-even occupancy?
An HOA fee raises your fixed monthly costs, which raises your break-even occupancy. Because the HOA fee is owed whether the unit is occupied or vacant, it adds directly to the cost side of your break-even calculation. A $300 monthly HOA fee on a property renting at $2,000 adds 15 percentage points to your break-even occupancy compared to an identical property with no HOA.
What happens if occupancy falls below break-even?
When occupancy falls below the break-even rate, the property does not generate enough rent to cover its fixed costs. You will need to cover the shortfall from other income or reserves. Extended periods below break-even — caused by prolonged vacancy, tenant non-payment, or an extended eviction — can create significant cash pressure, particularly if the shortfall compounds across multiple properties.
How can I lower my break-even occupancy rate?
You can lower your break-even occupancy by reducing fixed costs or increasing rent. Refinancing to a lower mortgage rate, challenging a property tax assessment, shopping your insurance policy, or eliminating a management fee by self-managing all reduce the cost side. Raising rent — where the market supports it — increases your income per occupied month. Both moves shift your break-even occupancy downward, giving you more buffer against vacancy.
How often should I recalculate my break-even occupancy rate?
Recalculate whenever your fixed costs change materially: after a remortgage, rent review, insurance renewal, or change in property management terms. Annual recalculation is a sensible baseline for most landlords. If your property has significant seasonal vacancy patterns, run the calculation at the start of each letting season so your vacancy tolerance figure stays current.
