Points to Percentage Calculator
Total points earned and points possible across assignments, converted to a percentage.
Teachers & StudentsOverall points percentage on the US standard scale
In a points-based gradebook there are no category weights to argue about: your grade is simply everything you earned divided by everything that was available. This calculator keeps the running total. Add each assignment with its points earned and points possible, and it shows the totals, the overall percentage and the letter grade, which is exactly the figure a points-system teacher will report.
How to use the Points to Percentage Calculator
- Add a row for each assignment or assessment.
- Enter points earned and points possible for each row.
- Check the totals as they update.
- Read the overall percentage and letter grade.
Formula
Each assignment influences the result in proportion to its points, so a 100-point test moves the percentage ten times as much as a 10-point quiz.
Worked example
Homework totals 46/50, quizzes 71/90 and tests 168/200. Overall: 285 / 340 = 83.8%, a B. Notice the quizzes look weak at 78.9%, but because tests carry 200 of the 340 points, the strong test record dominates the final percentage.
Good to know
The points system rewards consistency on the big items and makes mental arithmetic easy mid-term: divide your current earned by current possible for your standing, and add the points still available to see your ceiling and floor. If you can still earn every remaining point, your ceiling is (earned + remaining) / total possible. Teachers choosing between systems should note that points systems quietly weight by size, which is simple but can underweight frequent small practice work.
US grading scale reference
The table below is the US plus/minus scale used across this site. Where this tool offers other scales, the Canadian scale sets an A from 85% with a pass at 50%, and the Australian scale uses the bands HD (85%+), D (75-84%), C (65-74%), P (50-64%) and F (below 50%) on a 7.0 GPA.
| Letter grade | Percentage | GPA points |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently asked questions
How do I calculate percentage from points?
Add up all points earned, add up all points possible, divide the first total by the second and multiply by 100. This page keeps both totals for you.
What is 45 out of 60 as a percentage?
45 / 60 = 0.75, so 75%, a C on the US scale. Enter it as a single row here to confirm, or use the Test Grade Calculator for one-off scores.
Do all assignments count equally in a points system?
No. They count in proportion to their points. A 200-point final outweighs four 25-point assignments combined, which is the defining feature of the system.
How do I find my grade if some work is not yet graded?
Enter only graded work for your current standing. To see your best possible outcome, add the remaining work at full points; for the worst case, add it at zero.
Points system or weighted system: which is better?
Points are simpler and transparent; weights let a teacher value categories independently of size. The calculation must match the system in your syllabus, not preference.
