Both modes use the same weighted average formula — just solved in opposite directions.
Project My GPA
Enter hypothetical grades and see your projected cumulative GPA instantly.
Formula:
Projected GPA =
(CurrentGPA × CurrentCredits
+ Σ (Grade × Credits))
÷ TotalCredits
Find Required Grade
Enter a target GPA and the tool solves for the average grade you need in remaining courses.
Formula (reversed):
RequiredAvg =
(TargetGPA × TotalCredits
− CurrentGPA × CurrentCredits
− Σ FixedQualityPoints)
÷ OpenCredits
Step-by-Step Example (US 4.0)
- Your current standing: 3.0 GPA with 45 credits completed = 135 quality points.
- You add 3 courses (9 new credits): Mathematics B+ (3.3×3=9.9 QP), Physics A (4.0×3=12 QP), English B (3.0×3=9 QP).
- New totals: 135 + 9.9 + 12 + 9 = 165.9 quality points across 54 total credits.
- Projected GPA: 165.9 ÷ 54 = 3.07 → Letter grade B.
