GPA calculator.
Work out your grade point average. Enter your letter grades and the credit hours for each course and the calculator returns your GPA on the 4.0 scale, weighted by credits.

LiveEnter one grade per course, as letters or as 4.0-scale numbers, and the matching credit hours in the same order. GPA weights each grade by its credits.

How it works
Weighting by credits
Your GPA is a weighted average of your grades, where each course counts in proportion to its credit hours. You convert every letter grade to grade points on the 4.0 scale, multiply each by the course credits, add those up, and divide by the total credits.
So a high grade in a four-credit course moves your GPA more than the same grade in a one-credit course. The calculator does this for as many courses as you enter.

How GPA is calculated, why credits matter, and how scales differ.
How GPA is calculated
GPA is the credit-weighted average of your grade points. Each letter grade maps to a number on the 4.0 scale, you multiply it by the course credits to get quality points, sum the quality points across all courses, and divide by the total credits attempted.
Because it is weighted, courses worth more credits pull the average more strongly than smaller courses.
Why credit hours matter
A three-credit course counts three times as much as a one-credit course toward your GPA. That is why a slip in a heavy course hurts more, and why strong grades in your biggest courses matter most.
Entering the correct credit hours for each course is essential for an accurate result.
Weighted and unweighted scales
This calculator uses the standard unweighted 4.0 scale, where an A is 4.0 regardless of course difficulty. Many high schools also use a weighted scale that adds points for honours or advanced courses, pushing GPAs above 4.0.
Colleges often recalculate to their own scale, so always check how your institution counts grades.
Cumulative versus term GPA
A term GPA covers one semester; a cumulative GPA covers every course you have taken. To find a cumulative GPA, include all courses and their credits together, not just the current term.
Keeping a running total helps you see how a strong or weak term shifts the overall figure.
The formula
Points times
credits.
GPA is the sum of grade points times credits, divided by total credits, on the 4.0 scale.

GPA questions.
How do I calculate my GPA?
+
Convert each grade to 4.0-scale points, multiply by the course credits, add the results, and divide by the total credits. Enter your grades and credits above and the calculator does it.
What is a good GPA?
+
On the 4.0 scale, around 3.0 is a solid B average, 3.5 and up is strong, and 4.0 is a straight-A record. What counts as good depends on your school and goals.
Does A+ count as more than 4.0?
+
On the standard unweighted scale, A and A+ are both 4.0. Some weighted or honours scales award more, which can push a GPA above 4.0.
How do credit hours affect GPA?
+
Each course is weighted by its credits, so a grade in a four-credit course counts four times as much as the same grade in a one-credit course.
Is this GPA calculator free?
+
Yes. It is completely free with no sign-up, and every calculation runs locally in your browser, so nothing you enter is stored or sent anywhere.
