Enter the built density (dwelling units/area) and the typical density (dwelling units/area) into the Density Bonus Calculator. The calculator will evaluate the Density Bonus.

## Density Bonus Formula

The following two example problems outline the steps and information needed to calculate the Density Bonus.

DB = (BD-TD) / TD * 100

Variables:

- DB is the Density Bonus (%)
- BD is the built density (dwelling units/area)
- TD is the typical density (dwelling units/area)

To calculate the density bonus, subtract the typical density from the built density, then divide by the typical density and multiply by 100.

## How to Calculate Density Bonus?

The following steps outline how to calculate the Density Bonus.

- First, determine the built density (dwelling units/area).
- Next, determine the typical density (dwelling units/area).
- Next, gather the formula from above = DB = (BD-TD) / TD * 100.
- Finally, calculate the Density Bonus.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

built density (dwelling units/area) = 90

typical density (dwelling units/area) = 80

DB = (BD-TD) / TD * 100** **= ?
