Frequently Asked Questions
How do you calculate a weighted grade?
Multiply each category's grade by its weight, add those up, then divide by the total weight. For example, homework 90% (weight 20), midterm 80% (weight 30) and final 85% (weight 50) give (90×20 + 80×30 + 85×50) ÷ 100 = 84.5%. This calculator lets you add as many categories as you like and normalizes the weights automatically.
What letter grade is my percentage?
On the common US scale: A is 93–100%, A- 90–92, B+ 87–89, B 83–86, B- 80–82, C+ 77–79, C 73–76, C- 70–72, D+ 67–69, D 63–66, D- 60–62, and F is below 60%. The calculator shows your letter grade and the matching GPA points on the 4.0 scale.
Do the weights have to add up to 100%?
Not while you're still entering grades. This calculator divides by whatever total weight you enter, so a partial set of categories still gives a correct running grade. Once every category is in and the weights total 100%, the result is your true overall grade.
