Enter the number of prospective customers and the Rule of 7 into the calculator to determine the total number of exposures needed. This calculator can also evaluate any of the variables given the others are known.

## Rule Of 7 Formula

The following formula can be used to calculate the number of exposures needed to achieve the Rule of 7.

E = 7 * C

Variables:

- E is the total number of exposures needed
