Estimates, not official records
Every calculator on GradeCalcOnline produces an estimate based on the numbers you enter. These results are planning tools, not official academic records. Your school's official gradebook, your instructor's records, and your transcript are the only authoritative sources of your grades.
Verify against your syllabus
Calculator accuracy depends on inputs matching your course's real grading rules. Before trusting any result, confirm the details against your syllabus: category weights, whether any scores are dropped, how extra credit is handled, and whether your instructor applies a curve. A single missed detail, such as a dropped lowest quiz or a participation category, can shift the true grade away from the estimate.
Grading scales vary
GradeCalcOnline maps percentages to letter grades using the most widely used US grading scale, and shows the raw percentage alongside every letter so you can apply your own cutoffs. But schools customize their scales: some set an A at 90 flat, some use no plus or minus grades, and many colleges publish their own tables. If your school's scale differs, use the percentage result with your school's chart, not our letter.
GPA conventions differ
GPA math also varies by institution. Schools differ on plus and minus values, on how much weight AP, IB, or honors courses receive, and on whether failed or repeated courses count. Our calculators use the most common conventions; your school's registrar or student handbook defines the version that actually appears on your record.
Learning platforms show their own numbers
Canvas, Blackboard, and Moodle each compute grades with their own settings, and instructors do not always publish every category or keep the gradebook current. If our calculator disagrees with your LMS, the usual causes are an unpublished assignment category, a dropped score the LMS already removed, or weights that do not sum to 100%. Treat any mismatch as a reason to check the syllabus, not as proof that one side is wrong.
Decisions are yours
GradeCalcOnline is not responsible for decisions you make based on calculator estimates, including study planning, course selection, or expectations about admissions or scholarships. Use the tools to plan and to ask better questions, then confirm what matters with your teacher, counselor, or school.
