GPA Calculator
Weighted 4.0-scale GPA from grades and credits.
Enter courses to calculate GPA.
GPA Calculator turns a list of course grades and credit hours into a weighted grade point average on the standard 4.0 scale. Enter one course per line and see your GPA, total credits, and grade points update instantly in your browser.
How it works
Each line is parsed as a grade and credit hours pair. The tool converts each letter grade to its 4.0-scale point value, multiplies by credit hours, sums the results, and divides by total credit hours to compute the weighted GPA.
Benefits
- Computes a properly credit-weighted GPA, not a simple average
- Accepts a full semester or transcript in one paste
- Flags exactly which line has an invalid grade or credit value
- Calculates entirely client-side with no account needed
Use cases
- Check your GPA before it appears on an official transcript
- Estimate how a planned course load will affect your GPA
- Verify a school's GPA calculation for a specific term
- Compare cumulative GPA across multiple semesters
Best practices
- Use plus and minus grades exactly as your school records them
- Double-check credit hours match your official course catalog
- Recalculate cumulative GPA by combining all semesters in one list
- Confirm your institution uses a standard unweighted 4.0 scale
Common mistakes
- Averaging grade points without weighting by credit hours
- Typing grades with extra spaces or lowercase inconsistently
- Forgetting a course's credit hours, defaulting it incorrectly
- Assuming this matches a weighted honors/AP GPA scale above 4.0
Privacy
Grades and credit hours are parsed and calculated entirely in your browser. GPA Calculator does not upload or store your academic records on any server.
Frequently asked questions
- What format should I use for each course?
- Enter one course per line as "grade,credits", for example "A,3" for an A grade worth 3 credit hours.
- What grade point scale does this use?
- It uses the common unweighted 4.0 scale: A/A+ is 4.0, A- is 3.7, B+ is 3.3, down through F at 0.0, matching most U.S. college grading systems.
- How is the weighted GPA calculated?
- Each course's grade points are multiplied by its credit hours, those products are summed, and the total is divided by the sum of all credit hours.
- What happens if I enter an unrecognized grade?
- The tool reports which line has the unrecognized grade so you can fix it. Supported grades are A+ through F, including plus and minus variants.
- Does this support weighted (honors/AP) GPA scales above 4.0?
- No. This calculator uses a standard unweighted 4.0 scale. If your school uses a 5.0 weighted scale, the grade point values will need to be adjusted separately.
- Is my grade information uploaded anywhere?
- No. All parsing and GPA calculations run locally in your browser and are never sent to a server.
