Effective Field Goal Percentage Calculator

What is Effective Field Goal Percentage Calculator?

An effective field goal percentage calculator measures shooting efficiency while accounting for the extra value of three-point shots.

👉 In simple terms: It tells you how effective a player is at scoring, not just how often they make shots.

Important Terms:

  • Field Goals Made (FGM) = total shots made (2PT + 3PT)
  • 3-Point Field Goals Made (3PM) = shots made from beyond the arc
  • Field Goal Attempts (FGA) = total shots taken
  • Effective Field Goal % (eFG%) = adjusted shooting efficiency

👉 Why it matters: A three-pointer is worth 1.5× a two-pointer, so eFG% adjusts for that difference.

👉 Example:

  • FGM = 10
  • 3PM = 4
  • FGA = 20

Result:
eFG% = 60%

This means the player is scoring as efficiently as someone shooting 60% on two-point shots.

How to Use Effective Field Goal Percentage Calculator?

Your calculator matches real basketball stat tracking.

Step 1: Enter total field goals made
Step 2: Enter number of three-pointers made
Step 3: Enter total attempts
Step 4: Click Calculate
Step 5: View results

Output You’ll Get:

  • eFG% (effective efficiency)
  • FG% (regular shooting percentage)

Example:

  • FGM = 8
  • 3PM = 2
  • FGA = 16

👉 Output:

  • FG% = 50%
  • eFG% = 56.25%

To compare efficiency differences between players, you can also use a percentage point calculator.

How to Calculate Effective Field Goal Percentage Manually?

You can calculate eFG% quickly with basic math.

  1. Take total field goals made
  2. Add half the value of three-pointers
  3. Divide by total attempts

Effective Field Goal Percentage Formula

eFG% = (FGM + 0.5 × 3PM) ÷ FGA

5 Example Problems of Effective Field Goal Percentage

Example 1: Balanced shooting

FGM = 6
3PM = 2
FGA = 12

Result = 58.3%

Example 2: No three-pointers

ValueNumber
FGM5
3PM0
FGA10

Result = 50%

Example 3: Heavy 3-point shooter

FGM = 9
3PM = 5
FGA = 18

Result ≈ 63.9%

Example 4: Low efficiency

FGM = 4
3PM = 1
FGA = 20

Result = 22.5%

Example 5: Elite performance

FGM = 12
3PM = 6
FGA = 18

Result ≈ 83.3%

How to Interpret Your Effective Field Goal Percentage Results?

Your eFG% shows true scoring efficiency.

Interpretation Table:

eFG%Meaning
60%+Elite efficiency
50–60%Strong
45–50%Average
Below 45%Inefficient

👉 Key insight:
Two players with the same FG% can have very different eFG% depending on three-point usage.

When Should You Use Effective Field Goal Percentage Calculator?

This tool is essential for advanced basketball analysis.

Use it when:

  • Comparing player efficiency
  • Evaluating shot selection
  • Analyzing team offense
  • Scouting performance

👉 Benefits:

  • Rewards three-point efficiency
  • Gives a clearer performance picture
  • Helps identify high-impact players

For deeper performance analysis, combine this with a shooting percentage calculator or volleyball hitting percentage calculator.

What Are The Limitations of Effective Field Goal Percentage Calculator?

While powerful, eFG% has limits.

  • It ignores free throws
  • It doesn’t consider shot difficulty
  • It doesn’t reflect defensive pressure
  • It doesn’t include turnovers

👉 For a more complete metric, analysts often use true shooting percentage.

FAQs About Effective Field Goal Percentage Calculator

Q1: What is effective field goal percentage?

A1: It is a shooting efficiency metric that adjusts for the extra value of three-point shots.

Q2: Why is eFG% better than FG%?

A2: Because it accounts for the fact that three-pointers are worth more than two-pointers.

Q3: What is a good eFG%?

A3: Around 50–55% is good, while 60%+ is considered elite.

Q4: Can eFG% exceed 100%?

A4: Yes, in rare cases with extreme three-point efficiency.

Q5: Does eFG% include free throws?

A5: No, it only measures field goal efficiency.
