Effective field goal percentage (eFG%) calculator

Effective field goal percentage adjusts the standard FG% to credit three-pointers with the extra point they are worth: eFG% = (FGM + 0.5·3PM) ÷ FGA × 100. It gives a fairer picture of a shooter's efficiency than raw field goal percentage.

Field goal percentage (FG%) calculatorField goal percentage is the share of shots a player makes: FG% = field goals made ÷ field goals attempted × 100. It is the most basic measure of shooting accuracy in basketball, though it treats two- and three-pointers alike.True shooting percentage (TS%) calculatorTrue shooting percentage measures scoring efficiency across all shot types — field goals, three-pointers and free throws — at once: TS% = points ÷ (2·(FGA + 0.44·FTA)) × 100.

Unlike batting average, it weights extra-base hits, so a slugger who hits doubles and homers scores far higher than a singles hitter.Lift percentage of 1RM calculatorFind the weight to load for a given percentage of your one-rep max.Usage rate (USG%) calculatorUsage rate estimates the share of a team's offensive possessions a player uses while on the floor, through shots, free throws and turnovers: USG% = 100·((FGA + 0.44·FTA + TOV)·(Team MP ÷ 5)) ÷ (MP·(Team FGA + 0.44·Team FTA + Team TOV)). Team minutes default to 240 (5 players × 48 minutes).

Enter Field goals made (FGM), Field goals attempted (FGA), Three-pointers made (3PM) and the Effective field goal percentage (eFG%) calculator works out Effective FG% (eFG%) straight away. For instance, with Field goals made (FGM) = 8, Field goals attempted (FGA) = 15 and Three-pointers made (3PM) = 3 it returns Effective FG% (eFG%) = 63.33%.

How to use it

  1. Enter your values: Field goals made (FGM), Field goals attempted (FGA), Three-pointers made (3PM).
  2. Read the result instantly: Effective FG% (eFG%).

Frequently asked questions

How does the Effective field goal percentage (eFG%) calculator work?

It takes Field goals made (FGM), Field goals attempted (FGA) and Three-pointers made (3PM) and derives Effective FG% (eFG%) from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

3 values: Field goals made (FGM), Field goals attempted (FGA) and Three-pointers made (3PM). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Field goals made (FGM) = 8, Field goals attempted (FGA) = 15 and Three-pointers made (3PM) = 3, the calculator returns Effective FG% (eFG%) = 63.33%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What does it give for smaller values?

Scaled down to Field goals made (FGM) = 4, Field goals attempted (FGA) = 8 and Three-pointers made (3PM) = 2, Effective FG% (eFG%) comes out at 62.5%. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Running a league or a tournament: how many fixtures a format produces, how the table resolves ties, and what a team still needs to qualify.

What is the most common mistake?

Assuming tie-breaks work the same everywhere. Goal difference, head-to-head and goals scored are applied in a different order by nearly every competition, and the order decides the table.

What is the difference between the Effective field goal percentage (eFG%) calculator and the Field goal percentage (FG%) calculator?

This one returns Effective FG% (eFG%); the Field goal percentage (FG%) calculator returns Field goal % (FG%). That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

True shooting percentage (TS%) calculator is the closest one after this: True shooting percentage measures scoring efficiency across all shot types — field goals, three-pointers and free throws — at once: TS% = points ÷ (2·(FGA + 0.44·FTA)) × 100. The 0.44 factor approximates how many possessions free throws consume.

What else is worth having open alongside it?

Basketball shooting percentage calculator and Basketball rebound percentage (TRB%) calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from, and how current are they?

Fixture counts and point totals are pure combinatorics and hold for any competition. The tie-break order is set by each governing body's own regulations — check the one you are actually in.
