The breakeven occupancy ratio tells you exactly what percentage of nights you need booked to cover all your expenses. It's the most important risk metric in STR investing, more useful than projected cash-on-cash return because it shows what happens when things don't go according to plan.

What Is Breakeven Occupancy Ratio?
The breakeven occupancy ratio is the minimum percentage of nights your property must be booked to cover all expenses: mortgage, taxes, insurance, utilities, cleaning, platform fees, maintenance, and everything else. Below this threshold, you lose money. Above it, you profit.
Think of it as your “safety margin.” A property with a 45% breakeven ratio only needs to be booked half the year to stay afloat. A property with a 70% breakeven needs strong bookings year-round, leaving almost no room for slow seasons, new competitors, or market downturns.
Breakeven Occupancy Ratio Formula
Breakeven Occupancy Ratio =
(Monthly Expenses / Net Revenue Per Night) / 30.4 days
Breaking down the components:
- Monthly Expenses: All fixed costs (mortgage, taxes, insurance, utilities, HOA) plus averaged variable costs
- Net Revenue Per Night: Your nightly rate minus platform fees (~3%), cleaning cost per night, and maintenance reserve (~5%)
- 30.4: Average days per month (365/12)
Breakeven Ratio Calculation Example
Let's calculate the breakeven occupancy ratio for a real property:
Property Details
Purchase price
$375,000
Down payment (25%)
$93,750
Loan amount
$281,250
Interest rate
7.0%
Average nightly rate
$150
Average stay length
3 nights
Step 1: Calculate Monthly Expenses
Step 2: Calculate Net Revenue Per Night
Note: The cleaning fee you charge guests offsets your cleaning cost, so cleaning is revenue-neutral. We only account for the variable expenses (platform fee, maintenance) charged on that cleaning revenue.
Step 3: Calculate Breakeven Ratio
$2,659 / $134.53 = 19.8 nights | 19.8 / 30.4 = 65%
65% is on the high side. This property needs strong bookings year-round to stay profitable. One slow month could wipe out multiple months of gains. Consider negotiating the purchase price down or increasing your down payment to lower the breakeven ratio.

Breakeven Occupancy Ratio Benchmarks
Here's how to interpret your breakeven occupancy ratio:
Very safe investment with strong margin. Can weather significant downturns. These deals are hard to find in competitive markets.
Solid safety margin. Room for slow seasons without going underwater. This is the target range for most STR investors.
Workable but watch closely. Limited margin for error. Market should have strong, consistent demand. Have reserves ready.
Avoid unless you have exceptional confidence in the market and strong cash reserves. One bad month can cascade into losses.
What Affects Your Breakeven Ratio
Several factors influence your breakeven occupancy ratio. Understanding these helps you evaluate deals and structure offers:
Purchase Price
Higher price = higher mortgage = higher breakeven. Negotiating $25,000 off the price can drop your breakeven ratio by 3-5 percentage points.
Down Payment
More cash down = lower monthly mortgage = lower breakeven. Moving from 20% to 25% down can significantly improve your ratio.
Interest Rate
Every 1% increase in interest rate adds roughly 10% to your breakeven ratio. Shopping for the best rate matters enormously.
Nightly Rate (ADR)
Higher ADR means more revenue per night, lowering your breakeven. Properties with unique amenities or prime locations can command premium rates.
Operating Expenses
Every dollar saved on monthly expenses directly lowers your breakeven. Shop insurance, optimize utilities, negotiate with vendors.
How to Lower Your Breakeven Occupancy Ratio
If your breakeven ratio is too high, here are actionable ways to improve it:
- Negotiate the purchase price. Every $10,000 reduction lowers your breakeven by approximately 1-2%.
- Increase your down payment. More equity means a smaller loan and lower monthly payments.
- Shop for better financing. A 0.5% lower interest rate can save hundreds per month.
- Optimize for higher ADR. Invest in amenities that justify premium pricing like hot tubs, game rooms, or professional photography.
- Reduce operating costs. Smart thermostats, LED lighting, and efficient appliances cut utility bills. Shop insurance annually.
- Consider a co-host arrangement if self-managing isn't feasible. It's cheaper than full property management.

The Bottom Line
The breakeven occupancy ratio is the single best indicator of STR investment risk. While projected cash flow and ROI get more attention, breakeven tells you what happens when things don't go according to plan.
Aim for under 50% whenever possible. If a deal requires 65%+ occupancy just to break even, the projected returns aren't worth the risk unless you have exceptional market knowledge and cash reserves.
