Enter the total number of units and the total lot area (acres) into the Residential Density Calculator. The calculator will evaluate and display the Residential Density.

## Residential Density Formula

The following formula is used to calculate the Residential Density.

RD = U / LA
• Where RD is the Residential Density (units/acre)
• U is the total number of units
• LA is the total lot area (acres)

To calculate residential density, divide the total number of units by the total lot area.

## How to Calculate Residential Density?

The following example problems outline how to calculate Residential Density.

Example Problem #1:

1. First, determine the total number of units.
1. The total number of units is given as: 500.
2. Next, determine the total lot area (acres).
1. The total lot area (acres) is provided as: 6.
3. Finally, calculate the Residential Density using the equation above:

RD = #U / LA

The values given above are inserted into the equation below:

RD = 500 / 6 = 30 (units/acre)

Example Problem #2:

For this problem, the variables needed are provided below:

total number of units = 700

total lot area (acres) = 10

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

RD = #U / LA = ?
