Grade Calculator
Calculate your weighted overall grade from scores and their weights.
Calculate your overall weighted grade from your scores and their weights. Enter each score and how much it is worth — one "score,weight" per line — and the tool returns your weighted percentage and letter grade. A simple average treats a 5% quiz like a 50% final; weighting reflects what each assessment is actually worth.
To find what you need on a final, use the Final Grade Calculator.
Frequently asked questions
How do I calculate a weighted grade?
Multiply each score by its weight, add them, and divide by the total weight. Enter one "score,weight" per line and the tool does it for you.
Why not just average my scores?
A plain average ignores how much each assessment counts. Weighting gives the true grade when items are worth different amounts.
What letter grade will I get?
The tool maps your percentage to a letter (A/B/C/D/F), but always check your school's exact cutoffs.
Is my data private?
Yes, everything is calculated in your browser.
