Formula and method

Per-game average is shown when you enter games played. Informational estimate, not medical advice. Talk to a qualified health professional about your own situation.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Goals for = 45; Goals against = 30.
| Result | Value |
|---|---|
| Goal difference | +15 |
| Goals for per game | — |
Example 2
Inputs: Goals for = 28; Goals against = 35; Games played = 20.
| Result | Value |
|---|---|
| Goal difference | -7 |
| Goals for per game | 1.4 |
The first line is the headline result (goal difference). Below it the football Goal Difference Calculator lists goals for per game, which describe the same case from other angles. IEEE-754 double precision; shown to the decimals indicated.
Tie-breaker
Goal difference is the first tie-breaker in many league tables when teams are level on points, for example in the Premier League. Goals scored is usually next.
Per game
Entering games played gives goals for per game, useful for comparing teams with different games played. A negative difference means more goals conceded than scored.
How the result changes with goals for
Holding every other input at the first worked example, this table changes only goals for. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Goals for | Goal difference | Goals for per game |
|---|---|---|
| 23 | -7 | — |
| 45 | +15 | — |
| 90 | +60 | — |
| 180 | +150 | — |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Goals for: entering "-1" shows "Goals for must be at least 0." beside that field and no result.
- Goals against: left empty shows "Enter goals against." beside that field and no result.

Background: fitness estimates
Fitness formulas are estimates whose accuracy depends on the input. One-rep-max formulas such as Epley and Brzycki give different answers, and predictions from hard sets of a few repetitions are better than from sets of ten or more. Age-based maximum heart rate formulas can be off by 10 to 30 beats a minute for an individual; Tanaka's 208 − 0.7 × age is generally preferred to 220 − age but is still an estimate.
Pace models built from a race result assume a maximal effort and work best for distances from about 5 km to the marathon. Use the output as a guide, not a prescription.
Assumptions and limitations
- Games played optional
- Not a diagnosis
Estimates from formulas describe averages. They are not a training or medical prescription; check with a qualified professional before changing your exercise or diet.
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for goals for and goals against to confirm this.
