Calculator Results Are Estimates, Not Official Grades

Our grade calculators perform standard arithmetic on the numbers you enter — percentage averages, weighted averages, points totals, and GPA conversions. However:

  • Results depend entirely on your inputs. A mistyped score or weight produces a wrong result. Always double-check the numbers you enter against your syllabus or gradebook.
  • Grading scales vary. We use the standard US A–F / 4.0 GPA scale, but individual schools, districts, and professors may use different cutoffs (for example, some schools do not award A+ or use plus/minus grades differently). Always confirm the exact scale with your instructor.
  • Weights must total 100%. If your syllabus weights don’t add up correctly, the estimate will be off.

Only your instructor or school can issue your official grade. Nothing on this Site should be treated as an official academic record or a guarantee of any particular grade outcome.

Not Academic or Professional Advice

Content on grades-calculator.us — including guides, examples, and FAQs — is educational information, not academic advising, tutoring, or professional advice. Decisions about your courses, scholarships, or academic standing should be made in consultation with your teachers, counselors, or academic advisors.
