How to calculate a grade percentage
The formula is:
(Points earned ÷ Total points) × 100
Example: if you scored 42 out of 50, then (42 ÷ 50) × 100 = 84%, which is a B on a standard US scale.

Frequently asked questions
How do I calculate my grade percentage?
Divide the points you earned by the total possible points, then multiply by 100. For example, 42 out of 50 is (42 ÷ 50) × 100 = 84%.
What letter grade is 84%?
On a standard US scale, 84% is a B. Grades from 83% to 86% fall in the B band, while 87% and above moves you into B+ territory.
How do I calculate a weighted grade?
Multiply each category’s percentage by its weight, then add the results. For example, a 90% test worth 60% of your grade plus an 80% homework score worth 40% gives (90 × 0.6) + (80 × 0.4) = 86%.
How do I work out the score I need on my final?
Subtract the points you’ve already secured from the total you need, based on each component’s weight. Decide your target overall grade, multiply it by the total weight, then subtract the weighted points you already have to see what the remaining work must score.
