How to calculate your final grade
There are three common ways teachers work out a final grade. Use the one that matches your class.
1. Weighted categories
Each category counts a set amount. Multiply each score by its weight, add the results, then divide by the total weight.
Example: homework 92% (20%), quizzes 85% (30%), final 78% (50%).
92 × 20 = 1,840
85 × 30 = 2,550
78 × 50 = 3,900
8,290 ÷ 100 = 82.9%, a B
2. Total points
Add up all the points you earned. Add up all the points possible. Divide, then multiply by 100.
Example: homework 45/50, quiz 18/20, test 82/100, project 47/50.
Points earned: 45 + 18 + 82 + 47 = 192
Points possible: 50 + 20 + 100 + 50 = 220
192 ÷ 220 = 0.873, so 87.3%, a B
With points, bigger assignments count more on their own. The 100-point test matters five times as much as the 20-point quiz.
3. Simple average
Every grade counts the same. Add your grades and divide by how many there are.
Example: 92, 85, 78 and 88. That's 343 ÷ 4 = 85.75%, a B.
Your grade so far
In the middle of a term, enter only what's been graded. In weighted mode, your weights won't add up to 100 yet. That's fine. The calculator divides by the weight you've entered, so the result is your grade right now.

Frequently asked questions
Which mode should I use?
Check your syllabus. If it lists percentages for each part, like "Tests 40%", use Weighted. If your teacher adds up points, like "185 out of 200", use Points. If every grade counts the same, use Average.
What if my weights don't add up to 100?
That's fine. The calculator divides by the total weight you entered. So in the middle of a term you can enter only the parts you've finished and get your grade so far.
How do I calculate my final grade in a class?
Use the same method your teacher uses. For weighted grades, multiply each category score by its weight, add them up, and divide by the total weight. For points, divide the points you earned by the points possible. The sections above show both with examples.
Why is my weighted grade different from my average?
Because the categories don't count the same. If your lowest score is in the category with the biggest weight, your weighted grade will be lower than a plain average.
Can teachers use this as a gradebook calculator?
Yes. Enter one student's scores and your category weights to check a grade, or to see what a gradebook program should show. It's quicker than setting up a spreadsheet for a one-off check.
Which letter grade scale does it use?
The standard US scale. 90% and up is an A, 80–89% is a B, 70–79% is a C, 60–69% is a D, and below 60% is an F. See the full chart with plus and minus grades on the letter grade page.
