Grade Average Calculator
Calculate the average of multiple class grades or assignment scores. Get your overall percentage, letter grade, and grade point equivalent.
About This Calculator
Averaging your grades across multiple classes or assignments gives you a clear picture of where you stand academically — but simple averaging doesn't account for different credit weights, and converting between percentage, letter grades, and GPA points requires looking up conversion tables each time. Whether you are tracking five assignments in one class or five courses across your entire schedule, weighted or unweighted, the manual calculations are tedious and error-prone. Our grade average calculator computes your percentage, converts it to a letter grade, and shows the GPA equivalent on a standard 4.0 scale.
The Formula Behind This Calculator
Average = Sum of grades / Count Weighted = Sum(Grade * Weight) / Sum(Weights) Use weighted when points differ.
Understanding the math helps you verify results and make better decisions for your project.

How do I calculate weighted grades?
