Vacancy Break-Even Rate Calculator
Every rental has a break-even rent — the level at which monthly income equals monthly cost after vacancy loss. Drop below it and you're subsidizing the property. This calculator finds the floor so you know when pushing rent vs accepting a lower tenant is the right call.
Break-even rent
$2,420
Market rent cushion

Cushion %
-0.8%
Total monthly cost
$2,275
Annual cash at market rent
-$228
How the math works
Total cost $2,275/mo ÷ (1 − 6% vacancy) = $2,420 break-even rent. Market rent $2,400 is $20 BELOW break-even — this property loses money under current assumptions. Either raise rent 1% or cut operating costs.
At healthy 15% cushion, break-even should be ~$2,085 on a $2,400 market rent — that comes from lower debt service, lower tax, or leveraging a shared management structure.

How this calculator works
What this page estimates
This Vacancy Break-Even Rate Calculator is built to give a quick, browser-based estimate for vacancy break-even rate. Every rental has a break-even rent — the level at which monthly income equals monthly cost after vacancy loss. Drop below it and you're subsidizing the property. This calculator finds the floor so you know when pushing rent vs accepting a lower tenant is the right call. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the vacancy break-even rate result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this vacancy break-even rate estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
What's a healthy break-even cushion?
Market rent 15-25% above break-even. That means a vacancy spike or rate rise won't push you negative. Under 10% cushion: fragile. Over 40% cushion: either heavily under-leveraged or underpriced rent (leaving money on table).
Does break-even include capex?
Best practice: yes. Adding $200-$400/mo capex reserve is honest. Excluded from 'operating break-even' but should be included for 'true economic break-even.'
Why does vacancy matter here?
The formula divides total cost by (1 − vacancy %). A 5% vacancy means you need to charge ~5.3% higher rent to break even. A 10% vacancy = 11% higher. Vacancy assumption significantly shifts the floor.
How do I use this at negotiation?
Know your number before renewal negotiations. If a tenant asks for a $100/mo cut and you're $300 above break-even, that's easy. If you're $50 above, that cut puts you underwater.
