> The effective field goal percentage calculator finds two-point, three-point and effective field goal percentages, giving three-pointers 50% extra credit, plus the points scored.

## Inputs

- 2-point field goals made
- 3-point field goals made
- 2-point attempts
- 3-point attempts

## Results

- 2-point percentage
- 3-point percentage
- Field goal percentage
- Effective field goal percentage
- Points from field goals

## Formula

```
eFG% = (FGM + 0.5·3PM) ÷ FGA,  FGM = 2PM + 3PM,  FGA = 2PA + 3PA
```

## Explanation

A made three-pointer is worth 50% more than a two, so plain field goal percentage undervalues good three-point shooters. eFG% fixes this: the league average is around 53–55%.

### What each result means

- **2-point percentage** = [2-point field goals made]÷[2-point attempts]×100
- **3-point percentage** = [3-point field goals made]÷[3-point attempts]×100
- **Field goal percentage** = ([2-point field goals made] + [3-point field goals made])÷([2-point attempts] + [3-point attempts])×100
- **Effective field goal percentage** = ([2-point field goals made] + 1.5×[3-point field goals made])÷([2-point attempts] + [3-point attempts])×100
- **Points from field goals** = 2×[2-point field goals made] + 3×[3-point field goals made]

### Example values

How the main result changes when **2-point field goals made** changes and everything else stays at the example values above:

Inputs — 2-point field goals made: 105; 3-point field goals made: 36; 2-point attempts: 210; 3-point attempts: 95.

Results — 2-point percentage = 50 %; 3-point percentage = 37.89 %; Field goal percentage = 46.23 %; **Effective field goal percentage = 52.13 %**; Points from field goals = 318.

- **Field goal**: Any shot other than a free throw.

## FAQ

**What is a good eFG%?**
Above 55% is good for an NBA team; the best shooters exceed 60%.

**Why multiply threes by 0.5?**
