The free throw percentage in basketball is a statistic that measures a player's or team's success when shooting free throws. To calculate a free throw percentage, you divide made free throws by the free throws attempted. If a player attempted 15 free throws in a game and made 10 this is what his free throw percentage would be 0.66 or 66%.
