Education Calculators: GPA, Grades, and Study Tools

These education calculators help students, teachers, and parents work through everyday academic questions. Use the GPA, College GPA, or High School GPA Calculator to track performance, and the Weighted Grade or Final Grade Needed Calculator to see how coursework and exams affect a final result. The Test Grade and Grade Curve Calculators help with scoring, while Percentage to GPA and CGPA to Percentage help compare grading systems. Beyond grades, the Study Planner helps organize study time, the Attendance Calculator tracks missed classes, and the Reading Speed Calculator estimates how long an assignment may take.

Study Planning 3

Reading Speed

Enter the number of words you read and how long it took, and this calculator shows your reading speed in words per minute (WPM) plus how long any book or article will take you to finish.

Attendance

Enter the classes you attended, the total classes held, and your required attendance percentage. The calculator shows your attendance percentage, whether you meet the requirement, and how many classes you must attend — or can safely skip.

Study Planner

Plan your exam preparation by entering your exam date, the subjects with the hours each needs, and how many hours per day you can study. The calculator tells you the required hours per day, whether the plan fits, and how many days to give each subject.
