GPA Calculator

Calculate your semester GPA from course credits and letter grades on the common 4.0 scale, and optionally update your cumulative GPA with this term's results.

Courses this term
Rows left completely empty are ignored. Credits can be from 0.5 to 10 per course, up to 30 courses.
Cumulative GPA (optional)
Fill in both to see your new cumulative GPA including this term.

Uses the common 4.0 scale: A+ and A = 4.0, A- = 3.7, B+ = 3.3 … D- = 0.7, F = 0. Some schools count A+ as 4.3 or use other scales, so check your school's policy.

How to use the GPA calculator

For each course this term, enter the number of credits (or credit hours) and choose the letter grade you received or expect. The course name is optional and only helps you keep track. The form starts with five rows; use Add course for more (up to 30) and the remove button to delete a row. Rows that are left completely empty are ignored.

If you also want your overall GPA, fill in your current cumulative GPA and the credits completed so far. Then press Calculate GPA.

How GPA is calculated

Each letter grade is worth a number of grade points on the common 4.0 scale:

  • A+ and A = 4.0, 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

For every course, quality points = credits × grade points. Your GPA is the total quality points divided by the total credits, so courses with more credits count more.

The new cumulative GPA combines your past record with this term: (current GPA × credits completed + this term's quality points) / (credits completed + this term's credits).

Worked example

Suppose you took five courses: 3 credits with an A (12 points), 4 credits with a B+ (13.2), 3 credits with an A- (11.1), 2 credits with a C (4) and 3 credits with a B (9). That is 49.3 quality points over 15 credits, so your semester GPA is 49.3 / 15 = 3.29.

If you already had a 3.50 GPA over 45 credits, your new cumulative GPA is (3.5 × 45 + 49.3) / 60 = 206.8 / 60 = 3.45.

Good to know

  • Grading scales vary. Some schools give an A+ 4.3 points, some do not use plus and minus grades, and some weight honors or AP classes. Check your school's policy if your result needs to match an official transcript.
  • Pass/fail courses, withdrawals and transfer credits usually do not count toward GPA, so leave them out.
  • GPA is shown with two decimals; your school may round or truncate differently.

Frequently asked questions

What is the difference between semester GPA and cumulative GPA?

Semester (or term) GPA covers only the courses from one term. Cumulative GPA covers every graded course you have taken so far, weighted by credits.

Why does a course with more credits affect my GPA more?

GPA is a weighted average. Each grade is multiplied by the course's credits, so a 4-credit course counts twice as much as a 2-credit course.

Is an A+ worth 4.0 or 4.3?

It depends on the school. Many use 4.0 as the maximum, which is what this calculator does. Some schools give an A+ 4.3 points; in that case your official GPA may be a little higher than shown here.

What are quality points?

Quality points (also called grade points earned) are the credits of a course multiplied by the grade points of its letter grade. A 3-credit course with a B+ earns 3 × 3.3 = 9.9 quality points.

Should I include pass/fail courses?

Usually not. Pass/fail and similar ungraded courses normally give credit but no grade points, so they are left out of the GPA calculation. Check your school's rules to be sure.
