Grade Average Calculator
Add your grades and, optionally, their weights, to get the simple and weighted average instantly.
Simple vs. weighted average
Use the weight field to reflect exams or assignments that count more toward your final grade. Leave every weight at 1 to get a plain, unweighted average instead.
Frequently asked questions
What is the difference between simple and weighted average?
A simple average treats every grade equally, while a weighted average multiplies each grade by its weight (like credit hours or exam importance) before dividing by the total weight.
What passing grade should I use?
It varies by school and country — this tool defaults to 6, a common minimum in Brazilian schools, but you can change it to match your institution’s rule.
Can I add more than three grades?
Yes, use the "add grade" button as many times as needed; there is no limit to how many grades you can include.
