GPA3.67
Total Credits10
Quality Points36.70

This GPA calculator computes your grade point average by weighting each course grade by its credit hours, so heavier classes count more toward the result. It converts letter grades to points on the standard 4.0 scale (A = 4.0 down to F = 0), multiplies each by the course credits to get quality points, and divides the total quality points by the total credits. Use it for a single semester or for your cumulative record by entering every course at once.

Formula

GPA = Σ(grade points × credits) ÷ Σ(credits)

grade points
Value of the letter grade on the 4.0 scale (A=4.0, B=3.0, etc.)
credits
Credit hours assigned to the course
Σ(grade points × credits)
Total quality points across all courses
Σ(credits)
Total credit hours across all courses

How it works

  1. Add each course with its letter grade and the number of credit hours it carries.
  2. The calculator maps each grade to points (A 4.0, A- 3.7, B+ 3.3, B 3.0, and so on down to F 0) and multiplies by the credits to get quality points.
  3. It sums the quality points and the credits, then divides quality points by total credits to give the GPA, rounded to two decimals.

Worked example

Three courses: Biology (A, 4 credits), Calculus (B+, 3 credits), and History (A-, 3 credits).

  1. Quality points: A×4 = 4.0×4 = 16; B+×3 = 3.3×3 = 9.9; A-×3 = 3.7×3 = 11.1.
  2. Total quality points: 16 + 9.9 + 11.1 = 37; total credits: 4 + 3 + 3 = 10.
  3. GPA: 37 ÷ 10 = 3.7.

The GPA is 3.70 across 10 credit hours.

Frequently asked questions

What grade scale does this calculator use?
It uses the common unweighted 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, and F = 0. Plain A is treated as the top grade.
Why do credit hours matter?
GPA is a credit-weighted average, so a four-credit course influences your GPA more than a one-credit course with the same grade. Entering accurate credit hours is essential for a correct result.
How do I calculate a cumulative GPA?
Enter every course from all semesters together. Because the calculator divides total quality points by total credits, listing all courses at once produces the cumulative GPA directly.
Does this handle weighted or AP/honors GPAs?
No. This tool uses the standard unweighted 4.0 scale and does not add the extra points that weighted high-school systems give to AP or honors classes. It reflects an unweighted college-style GPA.
