GPA Calculator Online: Free GPA Calculator for Every Scale
A free online GPA calculator does the math for you — enter your courses, grades, and credits, and get your GPA instantly. No spreadsheets, no manual calculations, no guessing.
This guide explains how to use an online GPA calculator and which one to choose.
How to use an online GPA calculator
1. Pick your grading scale. The calculator needs to know which scale your school uses — US 4.0, weighted 5.0, Canada 4.3, India 10-point, Australia 7-point, or something else.
2. Enter your courses. For each course, enter the grade you earned and the credit value.
3. Read the result. The calculator converts each grade to points, weights by credits, and gives you your GPA.
The GPA calculator on this site supports multiple scales and works on any device.
What to look for in a GPA calculator
Not all calculators are equal. Here is what matters:
- Multiple scales: Your school might not use the standard 4.0 scale. A good calculator supports 4.0, 4.3, 5.0, 10-point, 7-point, and more.
- Credit weighting: The calculator must weight by credits, not just average your grades.
- Plus/minus support: If your school uses A-, B+, etc., the calculator should handle the 0.3 point adjustments.
- No sign-up: You should not need to create an account to calculate your GPA.
Why calculate your GPA online
- Speed: Get your GPA in seconds, not minutes.
- Accuracy: No arithmetic errors.
- Planning: Run scenarios — what if I get all A’s? What if I get a B in this course?
- Tracking: Calculate your GPA after each term to see your progress.
Frequently asked questions
Is there a free GPA calculator online?
Yes. The GPA calculator on this site is free, requires no sign-up, and works on any device.
Can I calculate my GPA without credits?
You can, but it will be less accurate. If you enter every course with 1 credit, you get a simple average of grade points. That is not the same as a credit-weighted GPA.
What if my school uses a different scale?
Check if the calculator supports your scale. If not, use the closest one and verify with your registrar.
Is an online GPA calculator accurate?
Yes, if you enter the correct grades, credits, and scale. The calculator uses the standard formula. Your official GPA comes from your institution.
