How to Use the Average Grade Calculator

Tracking your grades across an entire semester or year is the best way to avoid surprises when transcript season rolls around. Our Average Grade Calculator takes the mathematical guesswork out of finding your true academic standing, giving you an exact metric of your performance.

To use the calculator, begin by picking the type of grades you want to average: Percentage (like 85%), Letter Grades (like B+), or GPA points (like 3.0). You can enter them all in a single row or add a new row for each distinct assignment, test, or class.

If every grade holds the exact same weight — for example, averaging 5 pop quizzes together — simply enter your grades and check your calculated average at the bottom.

However, if you are averaging multiple full classes together, some classes matter more. A 4-credit AP Chemistry class will impact your average much more heavily than a 1-credit PE class. You can toggle on the credit/weight column to specify how heavily each grade should be factored into your final result.

As you build your list of grades, the calculator instantly updates your simple average, your weighted average, and an automatic mathematical conversion to a 4.0 GPA scale. There's no need to click a submit button or refresh the page.

If you're a teacher looking to average your entire classroom's test scores, just enter every student's score without weights to find the mean test grade. If you need a more advanced breakdown of how your class performed — including passing percentiles — use our Grade Curve Calculator.

And if you want to understand how this average impacts your permanent transcript, head over to the High School GPA Calculator. If your classes utilize weights, check out the weighted grade calculator.

To figure out your required exam scores based on your average, use the final grade calculator. Finally, if you want to estimate your total transcript based on these averages, try the semester grade calculator.

If this basic average isn't enough because your syllabus uses complex category percentages, switch to the Weighted Grade Calculator.

When the semester is almost over, you can figure out what exam score you'll need with the Final Grade Calculator. Lastly, project your full term with the Semester Grade Calculator.

Frequently Asked Questions

How do I calculate an average grade?
Add up all of your percentage grades, then divide that sum by the total number of grades you entered. This gives you the basic arithmetic mean, which is how standard unweighted grades work.
How is an average grade different from a GPA?
An average grade calculates your overall percentage performance across classes (e.g., an 88% overall). A GPA converts those percentages into grade points on a scale (like 1.0 to 4.0) and averages those points instead.
If I have two grades, what is the average?
If you only have two grades and they hold equal weight, add the two numbers together and divide by two. For instance, an 80 and a 90 average out to an 85.
Does an average grade calculator handle letter grades?
Yes, many calculators allow you to convert letter grades into standard numerical percentages according to a defined scale before averaging them together.
Should I calculate the mean, median, or mode for my grades?
For personal reporting, the basic mean is what schools use. The median (middle number) can show what a typical test score looks like if a 0% outlier is dragging the mean down. The mode is just the most frequent score occurring.
