Show steps
  1. Quality points = Σ (grade points × credits) = 36.3.
  2. Total credits = 10.
  3. GPA = quality points ÷ credits = 36.3 ÷ 10 = 3.63.

How to use the GPA calculator

  1. 1For each course, pick the letter grade and enter its credit hours.
  2. 2Use Add course for as many rows as you need; remove any with the ✕.
  3. 3Read your weighted GPA and total credits.

Weighted, not a plain average

An A in a 4-credit class and a C in a 1-credit class don’t average to a B. Credits are the weights: (4.0×4 + 2.0×1) ÷ 5 = 3.6. That’s why the big classes move your GPA the most.

Frequently asked questions

How is GPA calculated?

Each letter grade is worth grade points (A = 4.0, B = 3.0, and so on). Multiply each course's points by its credit hours, add those up, and divide by the total credits. Bigger courses count more.

What are the grade points on a 4.0 scale?

A/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 = 0.0. This is the most common US mapping.

Why weight by credit hours?

A 4-credit course should influence your GPA more than a 1-credit one. Weighting by credits gives each course pull proportional to its size — a simple average of the letter grades would not.
