Enter the number of successful IVF cycles and the total number of IVF cycles attempted into the calculator to determine the IVF success rate. This calculator can also evaluate any of the variables given the others are known.

Ivf Success Rate Formula

The following formula is used to calculate the IVF success rate.

SR = (NS / AT) * 100

Variables:

  • SR is the IVF success rate
  • NS is the number of successful IVF cycles
  • AT is the total number of IVF cycles attempted

To calculate the IVF success rate, divide the number of successful IVF cycles by the total number of IVF cycles attempted. Multiply the result by 100 to get the success rate in percentage.

What is a Ivf Success Rate?

IVF success rate refers to the likelihood of a successful pregnancy and birth resulting from an in vitro fertilization (IVF) cycle. This rate can vary greatly depending on various factors such as the age and health of the woman, the cause of infertility, the quality of the embryos, and the expertise of the fertility clinic. It’s typically expressed as a percentage, with higher percentages indicating a greater likelihood of success.

How to Calculate Ivf Success Rate?

The following steps outline how to calculate the IVF Success Rate.


  1. First, determine the number of successful IVF cycles (NS).
  2. Next, determine the total number of IVF cycles attempted (AT).
  3. Next, use the formula: SR = (NS / AT) * 100.
  4. Finally, calculate the IVF Success Rate.
  5. 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 IVF cycles (NS) = 75

Total number of IVF cycles attempted (AT) = 100
