Grade Calculator
Calculate your grades and percentages quickly and easily with our simple Grade Calculator.
(optional)
This free grade calculator helps you see where you stand in a course without guessing. Enter your scores and, if your class uses them, the weight of each category, and it returns your current percentage and the letter grade that goes with it. No sign-up is needed, and you can run it as often as you like.
It is built for students who want a clear answer before a test or a report card, for parents who would like to understand a gradebook at a glance, and for teachers who need a quick way to check a calculation. If you need something more specific, such as a GPA, an IB total or the score you need on a final exam, there is a dedicated calculator for that as well, and you will find all of them linked below.
How to use this grade calculator
- Open your syllabus or grading policy. Look for how the course is divided, for example homework 20%, quizzes 20%, tests 35% and the final exam 25%.
- Enter each graded item or category. Add your score as a percentage, or as points earned out of points possible.
- Add the weights. If the course is weighted, type the percentage for each category. If it simply adds up points, leave the weights equal.
- Leave ungraded work blank. Work that has not been marked yet should not count against you.
- Read your result. The calculator shows your overall percentage and the matching letter grade, so you can see how close you are to the next cutoff.
Check again after each major assignment or test. A grade that is reviewed regularly rarely becomes a surprise at the end of the term.
Weighted grades in plain English
In a weighted course, some work counts more than other work. A test worth 40% of the grade affects your result far more than homework worth 10%. The calculation itself is simple:
Weighted grade = (score × weight) added together for every graded category ÷ the total of those weights
A short example. Suppose homework is worth 30% and you have a 92, and tests are worth 70% and you have an 80.
- Homework: 0.30 × 92 = 27.6
- Tests: 0.70 × 80 = 56.0
Add them together and you get 83.6%, which is a B on most standard scales. If only part of the course has been graded so far, divide by the weights that have been used. That step is what keeps a partly finished term from looking worse than it really is. For a longer walk-through, read our guide to how weighted grades work.
Pick the right calculator
Different questions need slightly different tools. Here is a short guide to choosing the one that fits your situation.
For a single course
Use the class grade calculator when your syllabus lists weighted categories. If your teacher simply totals points, the points-based grade calculator will match the gradebook more closely. To combine several category averages into one number, try the grade percentage calculator.
For tests and assignments
The test grade calculator turns questions missed or answered correctly into a percentage. The assignment grade calculator handles rubric points, partial credit and late penalties.
For planning ahead
If you want to know what you need on an upcoming exam, the what-if grade calculator shows the score required to reach your target grade. Our article on what grade you need on your final explains the same method step by step.
For letters, levels and GPA
The letter grade calculator converts a percentage into a letter and grade points. Students can use the high school grade calculator for quarter and semester grades, or the college grade calculator for plus and minus cutoffs. The GPA calculator brings your courses together into a semester or cumulative GPA.
For other grading systems
IB Diploma students can total their points out of 45 with the IB grade calculator. Students in the Philippines can convert a general weighted average with the GWA to GPA calculator.
Common mistakes to avoid
- Counting ungraded work as zero. Many online gradebooks do this early in the term. Leave those items blank here to see your true current grade.
- Averaging percentages when the course uses points. A 50-point project and a 10-point quiz do not carry equal weight, even if both show a percentage.
- Using weights that do not match the syllabus. Small differences in weighting can move a result by several points. Copy the figures exactly.
- Leaving out missing assignments. If work was not submitted, enter it as zero. The result will be lower, but it will match what your teacher sees.
- Assuming every school uses the same letter scale. An 89.5 may be an A- in one course and a B+ in another. Your grading policy always has the final word.
Frequently asked questions
How do I calculate my grade?
Multiply each score by its weight, add the results, and divide by the total weight of the work that has been graded. In an unweighted course, divide total points earned by total points possible.
Is this grade calculator free?
Yes. Every calculator on this site is free to use, with no account or sign-up required.
What is the difference between a weighted and an unweighted grade?
In a weighted grade, categories such as tests or the final exam count for a set share of the total. In an unweighted grade, every point counts the same.
Why is my result different from my school portal?
Portals may count missing work as zero, drop the lowest score, or round in a particular way. Compare the inputs carefully, and ask your teacher if the gap remains.
Can I use this to find my GPA?
This tool gives your grade for a course. To turn several course grades into a GPA, use the GPA calculator, or read what a cumulative GPA is.
What letter grade is an 85%?
On most standard scales, 80% to 89% is a B, so 85% is a B. Some schools use plus and minus cutoffs, and you can compare common scales with the letter grade calculator.
