Grade and study calculators with visible formulas, examples, and warnings.
About GradePlan Tools
GradePlan Tools provides free calculators that help students plan grades, GPA, exams, assignments, study time, and TOEIC score goals.
The site is made for high school, college, university, and international students who need clear estimates without creating an account or setting up a spreadsheet.
Every calculator is designed for planning and learning. Results should always be checked against your syllabus, official grade portal, teacher, professor, or test provider.
Student-first writing
Plain English explanations that sound like a helpful senior student, not a textbook.
Planning only
No cheating tools, no fake promises, and no claim that estimates are official records.
