GPA Calculator

This GPA calculator uses the standard US 4.0 scale, where an A is worth 4.0 grade points, a B is 3.0, a C is 2.0, a D is 1.0, and an F is 0. Your GPA is the average of your grade points weighted by the number of credits each course is worth. Higher-credit classes influence your GPA more than lower-credit classes, which is why a four-credit lecture pulls more weight than a one-credit seminar.

The tool runs entirely in your browser. Your draft is stored only in localStorage on your device and is not sent to a server. You can switch between letter grades, percentages, and 4.0-scale points, which is useful when you are mixing transcripts from different schools or comparing a high school and college course on the same page.

1. For each course, enter the credit hours (often 1 in high school, 3 or 4 in college).
2. Select the grade you earned, or choose your preferred input scale.
3. Multiply each grade's point value by its credit hours to get quality points.
4. Add the quality points together, then divide by the total credits to get the GPA.

Suppose you took four 3-credit courses and earned A, A, B, and C. That is 4.0 + 4.0 + 3.0 + 2.0 = 13.0 grade points per credit. With 12 total credits, the GPA is 13.0 × 3 ÷ 12 = 3.25.

A GPA between 3.5 and 4.0 is generally considered strong, 3.0 to 3.5 is solid, and below 2.0 typically triggers an academic warning at many schools. What counts as a good GPA depends on your school, your program, and your goals — confirm your own thresholds with your counselor or academic advisor rather than relying on a single number.

Does this calculator handle plus and minus grades?

Yes. A− is treated as 3.7, B+ as 3.3, B as 3.0, and so on. If your school uses a different scale, you can switch the input to direct 4.0 points and type the exact value your school uses.

What if my school does not use a 4.0 scale?

Many schools use percentages or letter grades that map to different point values. Use the input mode that matches your school's transcript, and confirm the grade-point mapping with your registrar.

Are my grades saved anywhere?

The calculator can save a local draft in your browser so a refresh does not wipe your work. The draft stays on your device and is not sent to a server.

Can I include pass/fail courses?

Pass/fail courses usually do not affect GPA, so most students leave them out of the calculator. Check your school's policy on whether a Pass counts toward credit but not GPA.
