How to calculate your grade
Your syllabus decides how your grade is built. Most classes use weighted categories: homework, quizzes, tests and the final each count a set percentage. Enter each category's average and its weight, and the calculator multiplies, adds and divides exactly like a gradebook. Students and teachers can both use it in high school, and it works as a grade calculator for college classes too: copy the categories from your online gradebook and the math matches. If your teacher simply adds up points, switch to total points, which makes it a point grade calculator, and enter what you earned out of what was possible. The letter next to your percentage comes from your school's scale; the grading scale chart shows the letter for every percentage from 100 to 50 on the 10 point, plus and minus and 7 point scales.
Not every part of the class is graded yet? Leave those scores empty. Your grade so far is averaged over the weights that have a score, so mid term it is a current grade calculator, and the weight that is left is still to come. Open "What do I need on the rest?", type your goal, and you see the average you need on everything still ahead. Only the final exam left? The final grade calculator does that one step in a single line. Teachers curving a test before it goes in the gradebook can run the whole class through the grade curve calculator.
Weighted grade example
Homework counts 20% (you have 95%), quizzes 30% (88%), tests 30% (84%), and the final exam is the last 20%.
- Homework: 95 x 20% = 19 points.
- Quizzes: 88 x 30% = 26.4 points.
- Tests: 84 x 30% = 25.2 points.
- So far: 70.6 points out of the 80% graded, so 70.6 / 0.8 = 88.25%.
- For a 90% overall you need (90 minus 88.25 x 0.8) / 0.2 = 97% on the final.
Your current grade is 88.25% (B), and you need 97% on the final for an A.
Calculating grades by weight: the weighted grade formula
Determining weighted grades takes the same three steps in every weighted grade calculator and in your teacher's gradebook. Knowing the formula lets you check a posted grade and predict the next one without opening anything.
grade = (score1 x weight1 + score2 x weight2 + ...) / (weight1 + weight2 + ...)
Points based classes skip the weights: add every point you earned, divide by every point that was possible, multiply by 100. Enter each assignment as its own row and it works as an assignment grade calculator: a 20 point quiz and a 100 point test then count exactly in proportion to their points, which is why one big test can move a points grade so much.
What if: see what the next test does to your grade
Change any score and the grade updates as you type, so the calculator doubles as a what if grade calculator. Three questions it answers in seconds: what happens to an 85% if the next test is a 70, how much a missing homework row costs when the category is worth 15%, and whether the final can still lift a B+ to an A-. For that last one, open "What do I need on the rest?", type the grade you want and read the average you need on everything still ahead; the final grade calculator does the same for a final exam alone. Not sure where passing starts in your class? The passing grade guide covers the D, the 70 cutoff and the C rule for majors.
Questions and answers
How do I calculate my weighted grade?
Multiply each category score by its weight, add the results and divide by the total weight you entered. Homework 92% at 20%, quizzes 85% at 30% and tests 78% at 20% give 18.4 + 25.5 + 15.6 = 59.5 points over 70% of the course, an 85.0% average. The table under the result shows each step.
What if my weights do not add up to 100%?
That usually means part of the class is still ahead, such as the final exam. The calculator averages over the weights you entered, so your grade so far is correct, and the weight that is left is what the goal box uses to work out the score you still need.
Should I use weighted categories or total points?
Look at your syllabus. If it says something like homework 20%, tests 40%, use weighted categories. If every assignment simply has a point value and your grade is points earned divided by points possible, use total points. Many online gradebooks show which one your teacher uses.
How does extra credit count in this grade calculator?
In weighted mode, a category score over 100% raises that category. In points mode, add the extra credit points to points earned without adding them to points possible. Either way your grade can go above 100%, just as it does in most gradebooks.
What grade do I need on the rest of the class?
Open the goal box, leave the score empty for the categories still to come and type your goal. With 85% over 70% of the course and a goal of 90%, the remaining 30% needs an average of 101.67%, so a 90 is out of reach and the best possible finish is 89.5%.
Which grading scale does the calculator use for my letter?
The 10 point scale by default (A from 90, D from 60). Switch to pluses and minuses or the 7 point scale in the Letter grade scale menu under Change settings; the scale's source is linked under the result. The full grading scale chart lists every percentage from 100 to 50.
What is a weighted average, and how is it different from a plain average?
A plain average treats every score the same. A weighted average multiplies each category by how much it counts, so a 70% on tests worth 50% of the class pulls your grade down more than a 70% on homework worth 10%. Gradebooks use the weighted version, which is why a run of perfect homework does not fix a bad test average. So this page also works as a weighted average calculator for any set of scores and weights; give every row the same weight and it is a plain average grade calculator.
How do I calculate my grade with weights by hand?
Multiply each category average by its weight, add the results, and divide by the total weight you have used. Homework 95 at 20%, quizzes 82 at 30% and tests 78 at 50%: 95 x 0.2 + 82 x 0.3 + 78 x 0.5 = 19 + 24.6 + 39 = 82.6%, a B. The calculator shows this line with your own numbers under the result.
How do I calculate my overall grade?
Your overall grade combines every graded part of the class so far. With weighted categories it is the weighted average of your category averages; with total points, divide the points you earned by the points possible and multiply by 100, so 450 out of 500 points is 90%. Enter your categories above and the overall grade updates as you type.
Can I use this as a grade tracker through the semester?
Yes. Use it as a course grade calculator for the whole term: your rows are saved on this device, so you can come back after each test, update one score and see the new grade. The share link keeps the same rows in the URL if you want it on another device or want to send it to a parent or tutor.
