Shooting percentages are the core numbers for basketball scorers. They show how often shots go in, from the field, from three-point range, and from the free-throw line. A player who makes 8 of 20 field goals shoots 40 percent. That single number already tells coaches a lot about a scoring night.
This free calculator works out five shooting numbers at once: field-goal percentage, three-point percentage, free-throw percentage, effective field-goal percentage, and true shooting percentage. Enter makes and attempts for each shot type, plus total points. The tool shows all five instantly, with no sign-up and no download. Everything runs in your browser.
The basic formulas are simple. Field-goal percentage equals field goals made divided by field goals attempted, multiplied by 100. Three-point and free-throw percentages work the same way. For example, 8 of 20 field goals is 40 percent, 3 of 9 threes is 33.33 percent, and 6 of 8 free throws is 75 percent.
Effective field-goal percentage adjusts for the extra value of threes. It adds half a make for every three-pointer made, then divides by field-goal attempts. Here that is 8 plus 1.5, divided by 20, which is 47.50 percent. A player who shoots many threes looks better by this measure than by plain field-goal percentage, because threes are worth more points.
True shooting percentage goes further: it counts every way a player scores, including free throws. It divides points by twice the scoring attempts, where attempts are field-goal attempts plus 0.44 times free-throw attempts. The 0.44 factor estimates possessions used by free throws. Here, 25 points divided by twice 23.52 gives 53.15 percent. True shooting is the best single number for scoring efficiency.
To use the tool, enter field goals made and attempted first. Then threes made and attempted. Then free throws made and attempted. Finally enter total points, which should match the shots: 8 field goals with 3 threes plus 6 free throws is 25 points. If your points do not match, check the inputs before trusting the result.
How do you read the results? For field-goal percentage, 45 percent is solid for a guard and 55 percent is strong for a center. For threes, 35 percent is good and 40 percent is elite. For free throws, 80 percent is good and 90 percent is excellent. For true shooting, 55 percent is good and 60 percent is outstanding. Roles matter: centers shoot close shots, guards shoot harder ones.
Coaches use these numbers to build lineups and design plays. A player with a high true shooting percentage deserves more touches. A player with a high three-point percentage but a low overall percentage may be forcing bad twos. A player with a weak free-throw percentage is a target for late-game fouls, so that number gets extra attention in practice.
Common mistakes are easy to avoid. First, count three-pointers inside field goals too: field-goal attempts include threes. Second, do not double count: a made three is one field goal made and one three made. Third, use the same game or season for every input, or the advanced percentages will mix unlike samples and mislead you.
Young players often ask how to lift their percentages. The honest answer is shot selection first: take open shots, attack closeouts, and stop forcing contested long twos. Then comes repetition: free throws and catch-and-shoot threes reward daily practice more than any other skill. Track your five numbers with this calculator every week, and you will see which part of your scoring is really improving.
Tracking all five percentages across a season also shows which practice is paying off. If free-throw percentage climbs while three-point percentage stays flat, the extra gym time is working in one area and needs redirecting to another. Write the five numbers down weekly, compare them month by month, and let the trend decide what you practice next.
