How to Use the Occupancy Rate Calculator

This calculator helps property managers and investors measure how well their rental units are performing. Here is how to use it:

  1. Enter occupied units. This is the number of units currently rented and generating income. Count only units with active leases or paying tenants.
  2. Enter total units. This is the total number of rentable units in the property or portfolio. Include all units whether occupied or vacant.
  3. Enter monthly rent per unit. Use the average rent if units have different rates. This lets the calculator estimate the revenue impact of vacancies on an annual basis.
  4. Read the results. The occupancy rate shows as a percentage, with vacancy rate and vacant unit count below. The breakdown grid shows potential, actual, and lost annual revenue.

About Occupancy Rate

Occupancy rate is the percentage of available rental units that are currently occupied. It is one of the most important metrics for evaluating rental property performance and portfolio health. A higher occupancy rate means more consistent income and less revenue lost to vacancies.

Most residential properties target an occupancy rate above 90%. Rates below 85% may indicate pricing issues, poor property condition, or weak local demand. The vacancy rate is simply the inverse: if occupancy is 90%, vacancy is 10%. Tracking both metrics helps landlords identify trends and adjust strategy.

Frequently Asked Questions

What is a good occupancy rate for rental property?

A good occupancy rate for residential rental property is typically 90% or higher. In strong rental markets, rates above 95% are common. Rates below 85% may signal that rents are too high, the property needs improvements, or the market has excess supply. Commercial properties often have different benchmarks depending on the property type and location.

How do you calculate occupancy rate?

Occupancy rate equals occupied units divided by total units, multiplied by 100. For example, if you have 18 occupied units out of 20 total, the occupancy rate is (18/20) x 100 = 90%. The vacancy rate is the opposite: 100% minus the occupancy rate, which would be 10% in this example.

What is the difference between occupancy rate and vacancy rate?

Occupancy rate and vacancy rate are two sides of the same coin. Occupancy rate measures the percentage of units that are rented, while vacancy rate measures the percentage that are empty. They always add up to 100%. If your occupancy rate is 92%, your vacancy rate is 8%. Both metrics are used in property management and investment analysis.

How does occupancy rate affect rental income?

Every vacant unit represents lost income. If you have 20 units at $1,200 per month and 2 are vacant, you lose $2,400 per month or $28,800 per year. Higher occupancy directly increases revenue, which improves cash flow and property value. Most investors use occupancy rate to project realistic income and evaluate whether a property meets their return requirements.
