Enter the total number of free throws attempted and free throws made into the calculator to determine the free-throw probability.

## Free Throw Probability Formula

The following formula is used to calculate a free throw probability.

P(FT) = FTM / FTA * 100
• Where P(FT) is the free throw probability (%)
• FTM is the total number of free throws made
• FTA is the total number of free throws attempted

To calculate the free throw probability, divide the free throws made by the free throw attempts, then multiply by 100.

## What is a free throw probability?

Definition:

A free throw probability, also known as a free throw chance, is the likelihood that a basketball player will make any given free throw.

In other words, it’s the percentage of makes to attempts of free throws.

## How to calculate a free throw probability?

Example Problem:

The following example outlines how to calculate a free throw probability of a basketball player, also known as the free throw chance.

First, determine the total number of free throws attempted over a given period of time. To get an accurate probability, use a sample size of at least half a season.

In this example, the total number of attempts was 500.

Next, determine the total number of attempts made. In this case, the total number made was 400.

Finally, calculate the free throw probability using the formula above:

P (FT) = FTM / FTA * 100

P (FT) = 400/500* 100

P (FT) = 80%
