What the site does
The college GPA calculator uses course credits and letter grades. The high school GPA calculator compares unweighted and weighted GPA. The grade calculator combines weighted assignment categories. The final grade calculator estimates what score you need on a final exam to reach a target class grade.
How calculations work
GPA estimates use the grade point scale selected on the calculator. Honors courses add a 0.5 weighting boost and AP/IB courses add a 1.0 boost for weighted high school GPA. Non-GPA marks such as P, NP, W, and I are excluded from GPA averages.
Privacy approach
Calculator entries are stored in your browser using localStorage so your work can stay on the same device. CalcMyGrades does not require an account and does not ask for student ID numbers, official transcripts, or school credentials.
Important limitation
These tools provide estimates. Schools may use different grade replacement, transfer credit, pass/fail, repeated-course, honors, and rounding rules. Always confirm official academic decisions with your school, registrar, counselor, or academic advisor.
