Quick Answer
How do you calculate a weighted grade?
// Answer
Multiply each item’s score by its weight, add them up, and divide by the total weight. If a test worth 60% scored 80% and homework worth 40% scored 95%, the grade is (80×60 + 95×40) ÷ 100 = 86%. This calculator does it as you type.
Percentage to letter grade
| Percentage | Letter |
|---|---|
| 90–100% | A |
| 80–89% | B |
| 70–79% | C |
| 60–69% | D |
| Below 60% | F |

No. The calculator divides by the total weight you enter, so partial categories still give a correct weighted result.
Using a standard scale: 90+ = A, 80-89 = B, 70-79 = C, 60-69 = D, below 60 = F.
