GPA Calculator

Calculate your weighted GPA by entering your letter grades and the credit hours for each course. Supports standard A-F letter grades on the 4.0 scale. Add as many courses as you need - just keep grades and credits in the same order.

Comma-separated letter grades (A, A-, B+, B, B-, C+, C, C-, D, F) or numeric points (4.0, 3.3, ...).

Comma-separated credit hours for each course, in the same order as the grades.

How it works

Each course's quality points = grade points x credit hours. GPA = total quality points / total credit hours. The weighting by credit hours ensures that courses worth more credits have a proportionally larger effect on your GPA.

Formula
GPA = Σ(Grade points x Credits) / Σ(Credits)

Example. Grades A, B+, A-, C with credits 3, 4, 3, 3: (4x3 + 3.3x4 + 3.7x3 + 2x3) / 13 = 3.23 GPA.

Frequently asked questions
