Calculated result
Enter values and select Calculate.
Formula and method
Σ(score × weight) ÷ 100 is used for complete-course mode. Normalized mode uses Σ(score × weight) ÷ Σ(weight). The selected interpretation is always visible.
Worked example
Homework 90% × 20%, quizzes 80% × 30%, and exams 95% × 50% produce 89.5%.
Assumptions and limits
This forward weighted average does not reverse-solve a final exam score. Use Final Grade Calculator for that separate job.
Up to 50 rows are supported where rows are used. Calculations require finite bounded numbers and keep full precision internally; rounding is for display only.
School-policy boundary
Grading, GPA, credit, rounding, extra-credit, and course policies vary. This arithmetic tool does not determine admission, graduation, academic standing, scholarship, honors, athletic eligibility, or an official transcript result. Confirm the applicable syllabus or institutional policy.
