Calculate point differential from total points scored and allowed, or game by game with an optional per-game cap, for basketball, football or pickleball.
Point Differential Formula and Method
Raw margin in each game = points scored − points allowed
Enter two equal-length score lists in matching game order. A positive game margin means your side scored more; a negative margin means the opponent did. The raw total adds the margins, while the raw average divides that total by the number of games.
How to Use This Calculator
Choose raw or capped point differential, then enter equal-length score lists in matching game order. Separate entries with commas, semicolons or whitespace, without thousands separators. Each list supports up to 200 nonnegative scores from 0 to 1,000,000,000 points. For capped results, enter the positive symmetric margin limit used by your competition.
Worked Example
With the example inputs in the table, the result is 10 points. Raw totals and capped tiebreak totals are reported separately.
Sum credited margins = 5 + -5 + 10
Input and Example Guide
| Input or category | Example or weight | Entry guidance |
|---|---|---|
| Your scores, one per game (points) | 80, 95, 70 | Use matching entries separated by commas or spaces. |
| Opponent scores, in matching order (points) | 75, 100, 60 | Use matching entries separated by commas or spaces. |
| Apply a per-game symmetric margin cap? | No, raw differential | Choose the convention that applies to your record. |
Interpreting the Result
The optional cap limits each positive or negative margin before the credited total is added. Applying a cap to the final season total is a different calculation and can give a different answer. This symmetric cap is an entered tiebreak rule, not a universal rule across sports or tournaments.
The optional symmetric cap is an entered competition rule. This tool does not decide official tiebreak precedence.
Assumptions and Common Input Errors
Raw totals and capped tiebreak totals are reported separately. Use credited records rather than mixing estimates with final totals. A blank field is not treated as zero; enter zero explicitly when it is a valid observation.
Saving and Revising a Scenario
A successful calculation is saved in this browser and restored on the next visit. Editing an input labels the previous result as needing recalculation. Reset clears this calculator’s saved data and returns the score lists to their blank initial state. Other scripts on this site may access browser-saved values.
