Calculate field goal percentage (FG%) from shots made and attempted, add 3-pointers made for effective FG% (eFG%), or find the makes needed for a target.
How the Field Goal Percentage Calculator Works
Field goal percentage measures made field goals as a share of all field-goal attempts. The inverse modes turn a target percentage into an actionable whole number of makes or the largest attempt total supported by a known make count.
Formula: FG% = FGM / FGA x 100; makes needed = ceiling(attempts x target / 100); maximum attempts = floor(makes x 100 / positive target)
Choosing the Right Inputs
Use one consistent sample, such as a game, tournament, or season. Include both two-point and three-point field goals, but do not include free throws. Makes cannot exceed attempts.
| Makes | Attempts | FG% | Misses |
|---|---|---|---|
| 5 | 10 | 50.0% | 5 |
| 9 | 20 | 45.0% | 11 |
| 18 | 40 | 45.0% | 22 |
| 41 | 90 | 45.6% | 49 |
Understanding Your Results
The requested answer appears first, followed by the resulting percentage, makes, misses, attempts, and the percentage after the next make or miss. Target modes report total sample counts, not additional shots, using exact decimal whole-shot bounds. Enter counts up to 1,000,000; calculated attempts must also fit that limit. A zero-percent target has no finite maximum attempt count.
Worked Example
A player making 18 of 40 field goals has a 45.0% FG rate and 22 misses. To reach 50% in a fixed 40-attempt sample, the player needs 20 makes.
Assumptions and Limitations
FG% treats every made field goal equally even though three-pointers create more points. It also does not account for free throws, turnovers, role, shot difficulty, or game context.
