What is a point-system grade?
A point-system grade adds every point earned across all assignments in a course, then divides that sum by the total points the course was worth. Each point carries the same value no matter which assignment produced it, so a 200-point project moves the grade more than a 10-point warm-up simply because it holds more points. This is the opposite of a weighted-category gradebook, where a category's share is fixed in advance.
Points earned vs. points lost
This calculator asks for points possible and points lost because it also builds a chart of every possible score. To convert from points earned, subtract: a 480 out of 500 result is 20 points lost. The live result still reports earned over possible, the percentage, and the letter grade.
| Points possible | Points earned | Points lost | Grade |
|---|---|---|---|
| 100 | 91 | 9 | 91% — A− |
| 50 | 43 | 7 | 86% — B |
| 500 | 412 | 88 | 82.4% — B− |
| 1000 | 747 | 253 | 74.7% — C |
Points to a letter grade
The point total only produces a percentage — the letter still depends on the grading scale. On the standard scale an A starts at 93%; on the lenient scale it starts at 90%. Use the scale selector in the tool, or open the US grading scale to compare standard, strict, and lenient thresholds and their GPA values side by side.
Common point totals
Point system vs. weighted gradebook
If the syllabus lists category percentages — homework 20%, tests 50% — the course is weighted; use the gradebook calculator. If it only lists point values per assignment with no category shares, it is a point system and this page is the right tool. For a single test scored on questions, the grade calculator uses question-based labels instead.
Use the result with the correct policy
The calculator handles the arithmetic; the syllabus sets the official result. Confirm the assigned letter-grade scale, the rounding rule, whether extra-credit points can push the total above 100%, and whether any assignments are dropped before the point total is figured.
