GPA Calculator
Free GPA calculator. Enter your courses, credit hours and grades for an exact GPA — unweighted or weighted, with or without +/- grades, and cumulative across terms.
Your calculator is getting ready.
It runs separately so your grades stay away from advertising. If it doesn’t appear, open it directly.
Open the calculatorYour GPA, to the decimal.
GPA = total quality points ÷ total credit hours, where a course’s quality points = its grade points (A = 4.0, B = 3.0, …) × its credit hours. Courses with more credits count more.
Worked example
Four 3-credit courses graded A (4.0), B (3.0), A− (3.7) and B+ (3.3): quality points = 3×(4.0 + 3.0 + 3.7 + 3.3) = 42, over 12 credits, so GPA = 42 ÷ 12 = 3.50.
How to use the gpa calculator
Enter each course’s credit hours
Use the credits (or units) from your transcript or syllabus — often 3 or 4 per class. Credit hours are what weight each grade.
Pick the letter grade
Choose each grade. Turn on “+/- grades” if your school records A−, B+ and so on; turn it off for a straight A–F scale.
Add weighting if your school uses it
Turn on “Weighted” to add the Honors (+0.5) and AP/IB (+1.0) bonus per course. Leave it off for a standard unweighted GPA.
Read your GPA
The GPA, total credits and quality points update as you type. Add your prior GPA to get a cumulative figure.
Credit hours are the weights
A 4-credit course moves your GPA more than a 1-credit course with the same grade. That is why a simple average of your letter grades is usually wrong — the calculator multiplies each grade by its credits first, then divides by total credits.
Unweighted vs weighted
An unweighted GPA caps every course at 4.0. A weighted GPA adds a bonus for harder courses (commonly +0.5 for Honors and +1.0 for AP or IB), so it can go above 4.0. Colleges often recalculate to their own scale, so know which one a number refers to.
Cumulative vs semester
A semester (or term) GPA covers one term’s courses. A cumulative GPA covers everything so far. To roll a new term into your record, add your prior GPA and prior total credits — the calculator treats them as one large “course”.
