Calculating GPA from letter grades and credits usually means a spreadsheet or a school portal. The GPA Calculator does it in the browser: add courses with letter grade and credit hours and get weighted GPA—no sign-up and no data sent to a server.
How is GPA calculated?
GPA = sum(grade points × credits) ÷ total credits. Letter grades map to points (e.g. A=4, B=3, C=2, D=1, F=0). You can use A+, A, A-, B+, B, B-, etc. with standard 4.0 scale equivalents. Input: add courses with letter grade and credit hours; the tool computes weighted GPA. Some support different scales (e.g. 5.0). Calculation runs in your browser; your grades are not stored or sent. Use it to compute semester or cumulative GPA, plan what grades you need, or convert between grading systems. Schools may weight honors/AP differently or use a different scale—use the same scale and rules as your institution if your GPA does not match your transcript.
Key Features
- Formula — GPA = sum(grade points × credits) ÷ total credits. Letter grades map to points (e.g. A=4, B=3, C=2, D=1, F=0).
- +/- grades — Yes. A+, A, A-, B+, B, B-, etc. with standard 4.0 scale equivalents.
- Input — Add courses with letter grade and credit hours. The tool computes weighted GPA. Some support different scales (e.g. 5.0).
- Privacy — No. Your data is not sent to a server. Calculation runs in your browser. Your grades are not stored or sent.
- No account — Use as often as you need without sign-up.
- Transcript match — Schools may weight honors/AP differently or use a different scale. Use the same scale and rules as your institution.
How to Use the GPA Calculator
- Open the GPA Calculator tool.
- Add courses: letter grade and credit hours for each. View weighted GPA.
- Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- Semester GPA — Enter courses and grades for the term. Get GPA. Compare with target.
- Cumulative GPA — Add all courses (or paste from transcript). See overall GPA. Plan what grades you need to reach a target.
- Plan grades — "What if I get B in this course?" Add or change a grade and see new GPA.
- Convert systems — Some tools support 5.0 or other scales. Convert between systems if your school uses a different scale.
- Teaching — Demonstrate weighted average. Show how credits affect GPA.
- Applications — Compute GPA for applications or scholarships. Use the scale your institution expects.
Why Use the GPA Calculator Instead of Alternatives?
- vs. Percentage Calculator — Percentage Calculator does percent math. This tool converts letter grades to points and computes weighted GPA. Use this for GPA.
- vs. Loan Calculator — Loan Calculator is for loans. This tool is for grades. Different purpose.
- vs. Age Calculator — Age Calculator is for age. This tool is for GPA. Use both as needed.
- vs. Manual — No need to look up grade points or sum by hand. Add courses, view GPA.
Schools may weight honors/AP differently or use a different scale. Use the same scale and rules as your institution if your GPA does not match your transcript.
Benefits for Students, Counselors, and Parents
- Students — Quick semester or cumulative GPA. Plan what grades you need. No data sent.
- Counselors — Verify or explain GPA. Use same scale as school.
- Parents — Understand how GPA is computed. Support planning.
Common Mistakes
- GPA not match transcript — Schools may weight honors/AP differently or use a different scale. Use the same scale and rules as your institution.
- Wrong scale — 4.0 vs 5.0 vs 100. Choose the scale your school uses. Check +/- mapping (e.g. A- = 3.7).
- Missing courses — For cumulative GPA, include all courses and credits. Missing one changes the result.
- Forgetting to copy — The result is not saved. Copy or screenshot if needed.
