How it works
- Choose whether A+ is worth 4.00 or 4.33 according to your institution's policy.
- Add each course, select its letter grade from A+ through F and enter its credits.
- For cumulative GPA, enter both your previous GPA and completed credits.
- Review quality points, semester GPA and cumulative GPA; target planning remains optional.
Practical example
On the 4.00 scale: Mathematics A- (3.7) × 6 credits = 22.2 quality points; Programming A (4.0) × 9 = 36; Physics B+ (3.3) × 6 = 19.8; and English B (3.0) × 3 = 9. That is 87 points across 24 credits, so GPA = 87 ÷ 24 = 3.625, displayed as 3.63. Programming has the greatest influence because it carries 9 credits.
Formula and explanation
The formula is GPA = sum(grade points × credits) ÷ total credits. Multiply each letter grade's value by its course credits, add the quality points, and divide by all credits.
Courses with more credits affect GPA more. The calculator accepts A+–F and lets A+ equal 4.00 or 4.33; it does not convert percentages or 0–10 grades. Use your institution's official equivalencies.
For cumulative GPA, it combines previous GPA × previous credits with current semester quality points and divides by all previous and current credits.
