About this calculator
Free throw percentage is successful shots divided by attempts. Enter your totals and a target to see the current rate and consecutive makes needed to reach it.
Worked example

Formula and variables
P = m ÷ a × 100; i* = min { i : (m+i) ÷ (a+i) × 100 ≥ T }
- m
- Free throws made
- a
- Attempted
- P
- Percentage
- T
- Target percentage
- i*
- Consecutive makes needed
i* is searched iteratively from 1 to 500; if the target cannot be reached within 500 makes, it returns −1.
Frequently asked questions
How many consecutive makes are needed to reach the target percentage?
The calculator adds successful free throws one at a time until (makes + new makes) ÷ (attempts + new makes) reaches the entered target, checking up to 500 additional attempts. From 82 makes in 100 attempts, reaching 85% requires 20 straight makes: 102 ÷ 120 = 85%. A miss changes the starting totals and can increase the number needed.
