Effective FG% (eFG%) Calculator
Effective field goal percentage gives three-pointers their true extra value instead of counting every make the same. Enter makes, three-point makes, and attempts to get your eFG%, then see it against the current NBA league average.
Example: with Field goals made 10 FGM · 3-pointers made 3 3PM · Field goals attempted 20 FGA · Season (for the benchmark) 2025-26 → Effective FG%: 57.5%.

Why eFG% instead of raw field goal percentage
A made three-pointer is worth 50% more than a made two, but traditional field goal percentage (FGM ÷ FGA) counts them identically. Effective field goal percentage corrects for that by adding half a point of extra credit for every three-pointer made, so a player's shooting efficiency reflects the actual points produced per shot — not just the raw make rate.
How it’s calculated
eFG% = (FGM + 0.5 × 3PM) ÷ FGA. The 0.5 factor exists because a three is worth 1.5× a two, so each made three effectively counts as 1.5 field goals instead of 1. NBA league-average eFG% by season is pulled directly from Basketball-Reference's published per-game league averages.
This tool covers field goals only. It does not include free throws, so it will differ from True Shooting % for any player who draws contact often — see the FAQ below for that comparison. Results are for context and entertainment, not a substitute for official league statistics.
Common mistakes
- Comparing eFG% directly to raw FG% as if they measure the same thing — eFG% will always be equal to or higher than raw FG% whenever any threes are made.
- Forgetting that eFG% still excludes free throws — a player who gets to the line often will have a much higher True Shooting % than eFG%.
- Judging efficiency from a tiny sample — a 2-for-3 night on threes produces an eye-popping eFG% that says little about true shooting skill.
Frequently asked questions
Why not just use regular field goal percentage?
Regular FG% treats every made shot the same, so a player who makes 40% of their twos looks identical to a player who makes 40% of their threes — even though the three-point shooter scored 50% more points on the same number of makes. eFG% fixes that by giving three-pointers 1.5x the weight of a two, which is the actual point-value ratio.
What's the difference between eFG% and True Shooting %?
eFG% only adjusts for the extra value of three-pointers and ignores free throws entirely. True Shooting % (TS%) goes a step further and folds free throws into the denominator too, using total points scored divided by total shooting possessions (2 × (FGA + 0.44 × FTA)). TS% is the more complete efficiency number; eFG% is the simpler one that isolates pure field-goal shooting value. Try the True Shooting % calculator to see both side by side.
What counts as a good eFG%?
Since the introduction of the three-point line, NBA league-average eFG% has climbed from the high-.470s/low-.480s (1990s-2000s) to the mid-.540s in recent seasons (2023-2026), as teams have shot far more threes. As a rough guide today: below .500 is below average, .500-.540 is average-to-good, .540-.570 is very good, and above .570 is elite efficiency.
Does eFG% account for shooting volume or just accuracy?
Just accuracy (and shot value) — it says nothing about how many shots a player took or when. A player who goes 2-for-2 on threes has a spectacular eFG% (150%) but a tiny sample. eFG% is best read alongside field goal attempts, usage rate, and shooting volume, not as a standalone measure of a player's overall offensive value.
