GPA Calculator

About GPA Calculator

A GPA calculator on the 4.0 scale finds your grade point average by weighting each course grade by its credit hours. Add a row per class, pick the letter grade, and enter the credits — your GPA and total credits update instantly on the standard US 4.0 scale (A = 4.0, B = 3.0, and so on, with plus/minus steps). It works for a semester or a full college course load, with no sign-up, and everything runs in your browser.

Frequently asked questions

How do I calculate GPA from letter grades and credits?

Each grade is converted to points (A = 4.0, A- = 3.7, B+ = 3.3, …), multiplied by the course's credit hours, summed, and divided by the total credits. That gives a credit-weighted average — enter your classes and it does the math for you.

Does it handle plus and minus grades, and does A+ count as 4.0?

Yes. A+ and A both count as 4.0, and A-, B+, B-, and so on use their standard point values on the 4.0 scale.

What if my school uses a weighted or 5.0 scale?

This uses the common US 4.0 scale. Weighted, honors/AP, or 5.0 scales add bonus points, so results may not match schools that boost grades above 4.0.

Do I need to sign up, and is my data saved?

No sign-up, and nothing is saved. The calculation happens entirely in your browser — nothing is uploaded or stored.
