How it works
The calculator divides earned by possible and scales to 100. Partial credit is handled by using point totals rather than whole questions when needed.
Formula
Grade (%) = (Correct ÷ Total) × 100
How to use Test Grade Calculator
- Enter the number correct (or points earned).

Worked examples
Concrete numbers and cases you can check against the tool above.
43 correct out of 50
43÷50×100 = 86% — often a high B on a straight scale.
When to use Test Grade Calculator
Quick mental division fails on odd totals like 37/45. Teachers and students use the same math to align rubrics with letter-grade cutoffs.
Common use cases
- Score a multiple-choice practice test.
- Convert a rubric score out of 50 to a percent for the gradebook.
- Check whether you hit a 90% threshold for an A.
Inputs and outputs
- Correct/total counts
- Earned/max points

Frequently asked questions
- Does it round?
- Display rounding depends on the tool settings; gradebook policies may round differently.
- Can total be zero?
- No — division by zero is invalid. Enter a positive total.
- What about curved scores?
- This tool does not apply curves; enter adjusted points after your instructor’s curve.
