About occupancy rate

Physical occupancy = occupied unit-months ÷ total unit-months. Economic occupancy adjusts for concessions and delinquency. Most stabilized US rentals hover between 92% and 96% physical occupancy.

How this calculator works

What this page estimates

This Occupancy Rate Calculator is built to give a quick, browser-based estimate for occupancy rate. Calculate physical occupancy rate for a single rental or full portfolio, either from unit-months of vacancy or directly from a vacancy rate. 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 occupancy 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 occupancy 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.

How to Use

Pick the mode that matches your data: unit-months (for portfolios) or a direct vacancy rate.
For unit-months: enter units, months measured, and total unit-months vacant in that window.
For vacancy rate: enter the vacancy percentage to flip it into occupancy.
Review the resulting occupancy rate against stabilized benchmarks (92–96% is typical).
Plug the occupancy rate into cash flow and cap rate analysis for realistic income assumptions.

Frequently Asked Questions

What is a good occupancy rate?

Stabilized single-family and small multifamily rentals in strong markets run 92–96% physical occupancy. Workforce housing and higher-turn markets typically run 88–92%. Under 85% suggests pricing or management issues.

Is occupancy the same as vacancy?

They're complements: occupancy rate + vacancy rate = 100%. Both are usually reported as percentages. Lenders and operators often prefer occupancy for marketing and vacancy for underwriting.

What's a unit-month?

A unit-month is one unit available for rent for one month. A 10-unit building over 12 months has 120 unit-months of capacity. If three units were each vacant for two months, that's 6 vacant unit-months.

How does economic occupancy differ?

Economic occupancy adjusts for concessions, loss-to-lease, and delinquency. A building can be 100% physically occupied while collecting 95% of market rent because of concessions. Economic occupancy is the more honest metric for cash flow.
