Enter the total number of miscarriages and the total number of attempted births into the Miscarriage Rate Calculator. The calculator will evaluate the Miscarriage Rate.

## Miscarriage Rate Formula

The following two example problems outline the steps and information needed to calculate the Miscarriage Rate.

**MSR = #M / #B * 100**

- Where MSR is the Miscarriage Rate (%)
- #M is the total number of miscarriages
- #B is the total number of attempted births

## How to Calculate Miscarriage Rate?

The following example problems outline how to calculate Miscarriage Rate.

Example Problem #1:

- First, determine the total number of miscarriages.
- The total number of miscarriages is given as: 50.

- Next, determine the total number of attempted births.
- The total number of attempted births is provided as: 500.

- Finally, calculate the Miscarriage Rate using the equation above:

MSR = #M / #B * 100

The values provided above are inserted into the equation below and computed.

MSR = 50 / 500 * 100 = 10.00 (%)

Example Problem #2:** **

For this problem, the variables required are provided below:

total number of miscarriages = 60

total number of attempted births = 1,500

Test your knowledge using the equation and check your answer with the calculator..

MSR = #M / #B * 100** = ?**
