Turn points earned and points possible into a percentage grade, with a letter grade on a simple 90/80/70/60 scale.

85 out of 100 is 85%, a B. 43 out of 50 is 86%, also a B, while 27 out of 30 is exactly 90%, an A, and 17 out of 30 is about 56.67%, an F.
The percentage is the points earned divided by the points possible, multiplied by 100. The letter uses fixed thresholds: 90% and above is A, 80% to below 90% is B, 70% is C, 60% is D and anything lower is F. Points possible must be greater than zero, and the percentage is not rounded before the letter is chosen.
Boundaries are strict, so 89.5% is still a B unless your school rounds before assigning letters. Many institutions add plus and minus grades, weight categories differently or use numeric scales instead of letters, so treat the letter as a guide and the percentage as the portable result.
Enter the points you earned and the points available. 43 out of 50 is 86%, the same percentage as 86 out of 100, so tests with different totals can be compared fairly. 17 out of 30 is about 56.67%. The result is based only on the numbers entered: if an assignment has been scaled, curved or had questions removed, use the adjusted totals that the instructor uses rather than the raw marks on the paper.
The letter uses a simple scale: 90% and above is A, 80% to below 90% is B, 70% is C, 60% is D and below 60% is F. Boundaries are strict, so 89.5% remains a B unless your instructor rounds before assigning letters, and 27 out of 30 is exactly 90%, an A. Many schools add plus and minus grades or use entirely different boundaries, and many countries use numeric scales, so treat the letter as a guide and the percentage as the portable result.
Earned points may exceed the total when extra credit is awarded, so 105 out of 100 is shown as 105%. The tool evaluates one set of points at a time. A final course grade that weights homework, quizzes and exams differently cannot be found by averaging the percentages; multiply each category percentage by its weight and add the results. For grade point averages based on credits, use the GPA Calculator instead.
| Input | Result |
|---|---|
85 / 100 | 85% · B |
43 / 50 | 86% · B |
89.5 / 100 | 89.5% · B |
27 / 30 | 90% · A |
17 / 30 | 56.67% · F |
105 / 100 | 105% · A |
Yes, when extra credit is awarded: 105 out of 100 is shown as 105% and an A. The tool simply divides the numbers you enter, so if an assignment was curved or had questions removed, use the adjusted totals your instructor uses rather than the marks printed on the paper.
Not by averaging percentages, unless every category carries the same weight. Multiply each category percentage by its weight, such as homework 20% and exams 50%, then add the results. For a grade point average based on course credits, use the GPA Calculator instead.
No. This is a common United States style scale, but many schools set different cut-offs, and countries such as Germany, Japan and India use their own numeric systems. The percentage, such as 86% for 43 out of 50, transfers between systems; the letter does not.
