Enter the total amount of estrogen (pg/mL) and the total amount of progesterone (pg/mL) into the Estrogen to Progesterone Ratio Calculator. The calculator will evaluate and display the Estrogen to Progesterone Ratio.

## Estrogen to Progesterone Ratio Formula

The following formula is used to calculate the Estrogen to Progesterone Ratio.

EPR = E / P
• Where EPR is the Estrogen to Progesterone Ratio
• E is the total amount of estrogen (pg/mL)
• P is the total amount of progesterone (pg/mL)

To calculate the estrogen to progesterone ratio, simply divide the amount of estrogen by the amount of progesterone.

## How to Calculate Estrogen to Progesterone Ratio?

The following example problems outline how to calculate Estrogen to Progesterone Ratio.

Example Problem #1:

1. First, determine the total amount of estrogen (pg/mL).
• The total amount of estrogen (pg/mL) is given as: 20.
2. Next, determine the total amount of progesterone (pg/mL).
• The total amount of progesterone (pg/mL) is provided as: 15.
3. Finally, calculate the Estrogen to Progesterone Ratio using the equation above:

EPR = E / P

The values given above are inserted into the equation below and the solution is calculated:

EPR = 20 / 15  = 1.33

Example Problem #2:

For this problem, the variables required are provided below:

total amount of estrogen (pg/mL) = 20

total amount of progesterone (pg/mL) = 30
