Tool guide

How to use the Grade Percentage Calculator

The Grade Percentage Calculator divides points earned by points possible and multiplies by 100. Its letter grade is only a common estimate because schools and instructors use different grading boundaries.

What this tool is useful for

Convert a points score to a percentage.
Check the effect of missed points.
Estimate a common letter grade before consulting the official scale.

Practical example

A score of 45 out of 50 equals 90% because 45 ÷ 50 × 100 = 90.

Helpful tips

Weighted courses require a weighted-grade calculator rather than combining raw points blindly.
Extra credit can produce results above 100%.
Use the grading policy supplied by the school or instructor.
