What is the Grade Calculator?
A weighted grade multiplies each score by its weight and divides by the total weight. If homework is 20% and you scored 90, it contributes 18 points of the final grade.
The final-exam formula is: needed = (target − current × (1 − final weight)) ÷ final weight. A result above 100% means the target is out of reach unless there is extra credit.
Frequently asked questions
What if my weights don’t add up to 100%?
The current grade is calculated from the weights you have entered so far, which is how most gradebooks show a running grade.
Is the Grade Calculator free and private?
Yes. The Grade Calculator is free, needs no account, and runs entirely in your browser. What you type is never sent to a server or stored.
