The short answer

A GPA calculator multiplies each course's grade points by its credits, adds those quality points and divides by total credits. An A (4.0) in a 3-credit course contributes 12 quality points; add a B (3.0) in 4 credits for 12 more, and the GPA is 24 ÷ 7 = 3.43.

B holds grade points (4.0, 3.7, 3.3 …) and C holds credit hours. SUMPRODUCT creates the quality points, then dividing by total credits gives the credit-weighted GPA.

Universities vary slightly. Check your handbook before converting an official transcript.

Cumulative GPA

Add every completed course above and the calculator weights them together. To combine a prior GPA with a new term, use:

(oldGPA × oldCredits + newQuality) ÷ (oldCredits + newCredits)

Credit weighting matters. A 4-credit course moves your GPA more than a 2-credit course with the same grade. That is why a single low grade in a heavy course can outweigh two strong grades in lighter ones — and why this calculator multiplies before it divides.

How to use it

1Add one row per course and enter its credit hours.
2Choose the letter grade from the dropdown — the grade points fill in automatically.
3Check the total credits and quality points shown under the result.
4Use the Excel formula to build the same GPA sheet for your own records.

Questions about the gpa calculator

How is GPA calculated?

GPA = total quality points ÷ total credits, where quality points = grade points × credits. A 3-credit A and a 4-credit B give (4.0×3 + 3.0×4) ÷ 7 = 24 ÷ 7 = 3.43.

What are the grade points on a 4.0 scale?

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, F = 0. Some universities use slightly different values, so check your handbook.

Do 3-credit courses affect GPA more than 1-credit courses?

Yes. A course's influence is proportional to its credits. A 3-credit A adds 12 quality points, while a 1-credit A adds 4, so the 3-credit course moves the average three times as much.

How do I calculate cumulative GPA?

Add every completed course to the list and let the calculator weight them together, or combine a prior GPA with new work: (prior GPA × prior credits + new quality points) ÷ (prior credits + new credits).
