About this calculator
Break-even occupancy is the percentage of units that must be rented for a property's income to cover all its monthly costs, including debt service. This calculator finds that threshold and compares it to your assumed occupancy level.
How the calculation works
- Break-even occupancy % = total monthly expenses ÷ rent at 100% occupancy × 100
- Income at assumed occupancy = possible rent × assumed occupancy %
- Cash flow = income at assumed occupancy − total monthly expenses
Notes and assumptions
Break-even occupancy above roughly 85% leaves little margin for turnover or delinquency.
Because debt service is included, refinancing or paying down debt lowers the break-even point.
How it works in plain English
You enter total monthly operating expenses, including the mortgage payment, along with the total rent the property would collect if every unit were occupied. Dividing expenses by that fully-occupied rent figure gives the break-even occupancy percentage — the minimum occupancy needed to avoid a monthly loss.
You also enter an assumed occupancy percentage, which the calculator uses to estimate actual income and compare it against expenses to show a projected monthly cash flow at that occupancy level.
The gap between assumed occupancy and break-even occupancy is the occupancy cushion. A wider cushion means the property can absorb more vacancy, turnover, or delinquency before it starts losing money, while a thin or negative cushion means even small dips in occupancy could push the property into negative cash flow. Because debt service is included in expenses, refinancing to a lower payment directly lowers the break-even point.
The formula
- Break-even occupancy % = total monthly expenses / rent at 100% occupancy x 100
- Income at assumed occupancy = possible rent x assumed occupancy %
- Cash flow = income at assumed occupancy - total monthly expenses
Worked example
A property has $8,200 in total monthly expenses, including debt service, and could collect $10,000 a month if fully occupied. Break-even occupancy is $8,200 / $10,000 = 82%.
At an assumed occupancy of 95%, monthly income is $9,500, leaving a cash flow cushion of $1,300 a month. Since 95% is well above the 82% break-even point, the property has a comfortable 13-point occupancy cushion to absorb vacancy or turnover. Even if occupancy dropped to 85%, still above the 82% break-even level, the property would remain cash flow positive, which shows how much room this particular deal has before it starts losing money each month.
Frequently asked questions
Why does this calculator include debt service in expenses?
Including debt service shows the occupancy level needed to cover every cost of owning the property, not just operating it. This is the more useful break-even figure for an owner deciding whether the property can sustain itself month to month.
What's considered a healthy break-even occupancy?
A break-even occupancy above roughly 85% is generally seen as leaving little margin for turnover, seasonal vacancy, or delinquency. Lower break-even points give more of a cushion, though what counts as comfortable depends on how stable the local rental market is.
How can I lower my break-even occupancy?
Because debt service is the largest expense in most cases, refinancing to a lower payment, increasing the down payment, or extending the loan term will reduce the break-even threshold. Cutting operating costs or increasing possible rent also lowers it.
Does break-even occupancy account for rent increases over time?
No, it's a snapshot based on the numbers you enter for a specific period. If rents or expenses are expected to change, rerun the calculation with updated figures to see how the break-even point shifts.
What does a negative occupancy cushion mean?
It means your assumed occupancy is below the break-even level, so the property is projected to lose money even before accounting for any unexpected vacancy or repairs. This signals the deal may need renegotiated financing, higher rents, or lower expenses to work.
