GPA scale: what every GPA means
Pick a GPA to see its letter grade, percentage equivalent, and whether it's good in high school and college.
How the GPA scale works
Most U.S. schools report GPA on a 4.0 scale, where each letter grade is worth a set number of grade points — A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0 — with plus/minus grades landing in between (A- = 3.7, B+ = 3.3). Your GPA is the credit-weighted average of those points. Percentages are a separate, school-set convention, but they line up closely with the letter bands shown on each page.
Use the college, high school, or middle school calculators to find your own GPA, then come back here to see what it means.
Frequently asked questions
How do GPA, letter grade, and percentage relate?
On the 4.0 scale each letter maps to grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0) and a percentage band (A ≈ 93–100%, B ≈ 83–86%, and so on). Pick a value above to see the full breakdown.
What is a good GPA?
As a rule of thumb, 3.5+ is strong, around 3.0 is the national average and solid, and below 2.0 needs attention. Context matters — course rigor and your goals shape what 'good' means.
