GPA Calculator – Weighted, Unweighted and Cumulative GPA
Calculate your GPA on the 4.0 scale from letter grades and credits. Supports weighted GPA for honors and AP classes and cumulative GPA with past semesters.
GPA = total quality points ÷ total credits, where quality points = grade points × credits. An A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class give (12 + 12) ÷ 7 = 3.43.
How to use GPA Calculator
- Add a row for each course. A name is optional.
- Choose the letter grade and enter the credit hours (or units) of the course.
- For high school, tick “Weighted GPA” and mark honors or AP/IB courses.
- To get a cumulative GPA, open “Add previous GPA” and enter your current GPA and credits completed.
- Read your semester GPA, quality points and cumulative GPA.
How GPA is calculated
Your grade point average is a weighted average: classes with more credits count more. Each letter grade has a point value, which is multiplied by the course credits to give quality points. Add up all quality points and divide by the total number of credits.
GPA = Σ (grade points × credits) ÷ Σ credits
The 4.0 grade scale
| Letter | Points | Typical % |
|---|---|---|
| A+ / A | 4.0 | 93–100 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| D | 1.0 | 65–69 |
| F | 0.0 | below 65 |
This is the most common scale in the United States. Some schools give A+ 4.3 or use slightly different percentage ranges, so check your school’s handbook.
Weighted vs unweighted GPA
An unweighted GPA treats every class the same and tops out at 4.0. A weighted GPA rewards harder classes: many high schools add 0.5 for honors and 1.0 for AP or IB courses, so an A in AP Calculus counts as 5.0. The bonus is usually not given for failing grades. Colleges often recalculate GPAs in their own way, so report what your school uses.
Cumulative GPA
To combine semesters, the calculator multiplies your current GPA by the credits you have already completed, adds this semester’s quality points and divides by all credits together. That is why one great semester moves a cumulative GPA less when you already have many credits.
What is a good GPA?
A 3.0 (B average) is often the minimum for scholarships and many graduate programmes, while selective colleges look for 3.7 and above. Grades are only part of the picture: course difficulty, trends over time and activities matter too. If your GPA is lower than you hoped, an upward trend in later semesters is often viewed positively. For maths homework, try the LCM & GCF Calculator or the Slope Calculator.

Frequently asked questions
How do I calculate my GPA?
Multiply each grade’s points by the course credits, add the results, and divide by the total credits. The calculator does it automatically.
What is a weighted GPA?
A GPA that gives extra points for harder classes, usually +0.5 for honors and +1.0 for AP or IB, so it can go above 4.0.
How do I calculate cumulative GPA?
Multiply your previous GPA by your previous credits, add this term’s quality points, and divide by all credits combined.
Is a 3.5 GPA good?
Yes. A 3.5 is between a B+ and an A− average and is above the national average for high school and college students.
Does a pass/fail class count toward GPA?
Usually not. Pass/fail classes give credits but no grade points, so leave them out of the calculation unless your school says otherwise.
