GPA Calculator

Calculate your semester GPA from letter grades and credit hours on a 4.0 or 4.3 scale, and combine it with a previous GPA to get your cumulative GPA.

How to use the GPA Calculator

  1. List your courses, one per line, as the course name, then the grade, then the credit hours, for example Chemistry B+ 4. The name is optional.
  2. Use letter grades (A, A-, B+ …) or grade points such as 3.7.
  3. Choose whether your school counts an A+ as 4.0 or 4.3.
  4. To get your cumulative GPA, enter your previous GPA and the number of credits it covers.
  5. The result updates instantly as you type. There is no button to press.
  6. Use Copy result to copy the figures, or Copy link to share a link that reopens the GPA Calculator with the same inputs.

How it works

Grade point average (GPA) summarises academic performance as a single number, most commonly on a 4.0 scale used by universities and high schools in the United States and many other countries. Each letter grade is converted into grade points (A = 4.0, B = 3.0, C = 2.0 and so on, with plus and minus grades in between) and then weighted by the course's credit hours, so a 4-credit course counts twice as much as a 2-credit one.

Multiplying the grade points by the credits gives quality points. Your GPA is the total quality points divided by the total credits. To find a cumulative GPA across several terms, don't average the term GPAs. Combine the quality points and credits instead, because terms with more credits should carry more weight. This calculator does that when you enter your previous GPA and credits.

Schools differ in the details. Some count an A+ as 4.3, some don't use minus grades for D, and many exclude pass/fail courses and withdrawals from the GPA entirely, so leave those out. Weighted high school GPAs, which add points for honors or AP courses, use a different scale. Check your school's handbook for its exact table.

Formula

Quality points = grade points × credits GPA = Σ quality points / Σ credits Cumulative = (old GPA × old credits + new quality points) / (old credits + new credits)

Scale: A/A+ 4.0 (or 4.3), A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0.

Example

Calculus A (4 credits) = 16.0 quality points, English B+ (3) = 9.9, Biology A− (4) = 14.8 and History C (2) = 4.0. That is 44.7 quality points over 13 credits, so the semester GPA is 44.7 ÷ 13 = 3.44. If your previous GPA was 3.20 over 30 credits, your cumulative GPA becomes (96 + 44.7) ÷ 43 = 3.27.

Frequently asked questions

Do pass/fail courses count towards GPA?

Usually not. Most schools exclude pass/fail, audited and withdrawn courses from GPA. Leave them out of the list.

How do I raise my GPA?

Higher grades in courses with more credits move your GPA the most. The more credits you already have, the more slowly your cumulative GPA changes, so early terms matter a lot.

What is a good GPA?

A 3.0 (B average) is often the minimum for many graduate programs and scholarships, while 3.5 and above is generally considered strong. Expectations vary by school and field.
