About this calculator
Score % = correct answers ÷ total questions × 100
If questions are worth different points, use points instead: points earned ÷ points possible × 100. Count unanswered questions as wrong unless your test says otherwise, so the total is every question on the test. Scores above 100% are possible when there are bonus points.
The chart under the result places the score on the common US 10-point letter scale (A 90–100, B 80–89, C 70–79, D 60–69, F below 60). Many schools use plus and minus grades or stricter cutoffs, so check your syllabus; other countries use different scales entirely.
Tests with a penalty for wrong answers, or scores reported on a scaled range (such as the SAT's 200–800 per section), have their own conversion and are not a simple percentage.
| Percentage | Letter grade | GPA points (4.0 scale) |
|---|---|---|
| 90–100% | A | 4.0 |
| 80–89% | B | 3.0 |
| 70–79% | C | 2.0 |
| 60–69% | D | 1.0 |
| Below 60% | F | 0.0 |
How to use
Enter the number of correct answers and the number of questions. The default, 38 out of 50, gives 38 ÷ 50 × 100 = 76%, a C on the 10-point scale. For a 25-question quiz with 22 right, 22 ÷ 25 × 100 = 88%, a B (B+ where plus and minus grades are used). For a test scored in points, 87 points out of 120 gives 72.5%.
Frequently asked questions
How do I calculate a test score percentage?
Divide the number you got right by the total number of questions and multiply by 100. 17 out of 20 is 17 ÷ 20 × 100 = 85%.
How do I handle questions worth different points?
Add up the points you earned and divide by the total points available. A test with 40 one-point questions and a 60-point essay has 100 points; 35 questions right and 45 essay points is 80%, not 35 ÷ 41.
What letter grade is my percentage?
On the common US 10-point scale, 90% and above is an A, 80–89 a B, 70–79 a C, 60–69 a D and below 60 an F. Schools that use plus and minus grades often split each band, for example 87–89 as B+ and 80–82 as B−.
