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 to Use

  1. 1Enter up to 5 grades as percentages.
  2. 2Leave unused fields at 0 — they will be excluded from the average.
  3. 3Review your average percentage, letter grade, and GPA equivalent.

When to Use

  • Checking your overall performance across multiple courses or assignments.
  • Calculating what your report card average will look like.
  • Determining if your average meets a minimum requirement.

Tips

  • For weighted grades (where some assignments count more), use a weighted grade calculator instead.
  • One very low grade can significantly drag down your average — consider asking about extra credit or grade replacement.
  • Track your grade after each assignment to catch downward trends early.

FAQ

What letter grade is 85%?

On a standard 10-point scale, 85% is a B. On some scales it is a B+. The specific cutoffs may vary by institution — always check your syllabus.

How do I calculate weighted grades?

Multiply each grade by its weight (as a decimal), sum those products, then divide by the total weight. For example, with a midterm (30%) at 85 and final (70%) at 92: (85x0.30 + 92x0.70) = 89.9%.

What GPA is a B+ average?

A B+ typically equals 3.3 on a 4.0 scale. An A is 4.0, A- is 3.7, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0.
