Enter the number of successful Vbac deliveries and the total number of attempted Vbac deliveries into the calculator to determine the Vbac Success Rate. This calculator can also evaluate any of the variables given the others are known.

## Vbac Success Rate Formula

The following formula is used to calculate the Vbac Success Rate.

SR = (V / T) * 100

Variables:

- SR is the Vbac Success Rate (%) V is the number of successful Vbac deliveries T is the total number of attempted Vbac deliveries

To calculate the Vbac Success Rate, divide the number of successful Vbac deliveries by the total number of attempted Vbac deliveries. Multiply the result by 100 to get the success rate in percentage.

## What is a Vbac Success Rate?

VBAC stands for Vaginal Birth After Cesarean. The VBAC success rate refers to the percentage of women who, after having one or more cesarean deliveries, successfully give birth vaginally in subsequent pregnancies. This rate can vary depending on several factors, including the reason for the initial cesarean, the type of uterine incision used in the cesarean, and the mother’s overall health and pregnancy conditions. According to the American Pregnancy Association, 60-80% of women who attempt a VBAC have a successful vaginal delivery.

## How to Calculate Vbac Success Rate?

The following steps outline how to calculate the Vbac Success Rate:

- First, determine the number of successful Vbac deliveries (V).
- Next, determine the total number of attempted Vbac deliveries (T).
- Next, use the formula SR = (V / T) * 100 to calculate the Vbac Success Rate.
- Finally, calculate the Vbac Success Rate.
- 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.

Number of successful Vbac deliveries (V) = 45

Total number of attempted Vbac deliveries (T) = 60
