Disclaimer

The calculators on this site use standard U.S. grading conventions (e.g. A = 4.0, 90%+ = A). Your school, district or university may use different scales, weights or rounding rules — always confirm with your own syllabus, teacher or registrar. Results are estimates to help you plan, not an official record of your grades.

Accuracy of results

We test every calculator against reference values and review our formulas regularly. However, results depend entirely on the numbers and assumptions you enter, and simplified models cannot capture every real-world factor. Use the results as a starting point, not a final answer.
