## Marginal Benefit Formula

The following equation can be used to calculate the marginal benefit of a good or service.

- B1 and B0 are the final and initial benefits respectively
- Q1 and Q2 are the final and initial quantities respectively

To calculate the marginal benefit, divide the change in benefit by the change in quantity.
