🎓 GPA Calculator

What This GPA Calculator Does

This calculator works out your grade point average from your course grades and their credit weights. You enter each course's grade and how many credits it carries, and it returns your weighted GPA. Because courses with more credits count more toward your average, a simple average of your grades would be misleading — this tool gives you the figure schools actually use.

Whether you are tracking progress toward a scholarship threshold, checking whether you will make the dean's list, or just want to know where you stand before final grades post, a GPA calculation answers it in seconds rather than guesswork.

How a Weighted GPA Is Calculated

GPA is a weighted average. Each grade is converted to grade points — typically a 4.0 scale where an A is 4.0, a B is 3.0, and so on — and then multiplied by the number of credits for that course. You add up all those weighted points, add up all your credits, and divide the first total by the second. The result is your GPA.

The weighting is what makes it more than a plain average. A top grade in a one-credit elective moves your GPA far less than the same grade in a four-credit core course, because the core course contributes four times the weight. This is why two students with the same letter grades can have different GPAs if their course loads differ — and why this calculator asks for credits, not just grades.

A Note on Different Grading Scales

Grading scales are not universal, and this matters when interpreting a GPA. Many schools use the standard 4.0 scale, but some use weighted scales that award extra points for honors or advanced courses, pushing a GPA above 4.0. Others use plus and minus grades that map to values like 3.7 or 3.3. When comparing GPAs across schools, it is worth knowing which scale each uses, because the same number can mean different things.

This calculator works on the common point-and-credit model, which covers the great majority of cases. If your institution uses an unusual scale, the underlying method is the same — convert each grade to its point value, weight by credits, and average — so you can still rely on the result as long as you enter the grade points your school assigns.

Frequently Asked Questions

How is GPA calculated?

Convert each grade to grade points, multiply by the course's credits, add up all the weighted points, and divide by the total credits. The result is your weighted grade point average, which is what this calculator computes.

Why are credits part of the calculation?

Because courses carry different weights. A four-credit course affects your GPA four times as much as a one-credit course with the same grade, so credits must be included for the average to be accurate.

Can my GPA be above 4.0?

On a standard unweighted 4.0 scale, no. But some schools use weighted scales that award extra points for honors or advanced courses, which can push a GPA above 4.0. It depends entirely on your institution's grading system.

How do I find the grade I need to hit a target GPA?

Enter your known grades and credits, then experiment with the grade in your remaining course until the result reaches your target. Because the calculation is instant, you can quickly see what each possible grade does to your average.
