True Shooting Percentage Calculator

True Shooting Percentage exists because standard field-goal percentage is a flawed efficiency metric — it ignores both the extra point a made three is worth and the free throws a player draws by getting to the line. This calculator computes True Shooting Attempts first (TSA = FGA + 0.44 × FTA), where the 0.44 coefficient is an empirical estimate of how many "possessions" a free throw attempt represents, since free throws often come in pairs or as part of and-one situations rather than one-for-one with field goal attempts. TS% is then points divided by twice the TSA, expressed as a percentage — dividing by 2×TSA rather than TSA alone because points already reflect makes worth 2 or 3, so this normalizes everything back to a per-shot-equivalent basis.

The calculator also reports Effective FG% (eFG% = (FGM + 0.5×3PM) / FGA), a narrower efficiency stat that credits made threes as worth 1.5 field goals but — unlike TS% — leaves free throws out entirely, useful for isolating field-goal shot selection from foul-drawing ability. Standard FG% and raw points-per-shot are included for context, and the calculator compares the computed TS% against a rough modern-NBA league-average benchmark of about 57.5%, reporting the gap directly as TS% vs League Avg — a positive number means above-average efficiency, a negative one means below. A common mixup: TS% and eFG% will diverge most for players who get to the free-throw line often, since eFG% has no way to reward that — a high-volume free-throw shooter can look mediocre on eFG% but strong on TS%.
