How to use the GPA calculator

  • GPA from grades: choose the letter grade and enter the credits (or units) for each course. Mark honors, AP or IB courses to see your weighted GPA too. Add your current GPA and the credits it covers to get your new cumulative GPA.
  • CGPA to percentage: converts a 10-point CGPA, as used by CBSE and many Indian universities, into a percentage. CBSE's formula is used unless you enter your university's own.

GPA formula

GPA = Σ (grade points × credits) ÷ Σ credits
Cumulative GPA = (old GPA × old credits + new grade points) ÷ all credits

Worked example

Five courses: A (3 credits), B+ (4 credits, AP), A− (3), C+ (3) and B (2).

Grade points = 12 + 13.2 + 11.1 + 6.9 + 6 = 49.2 over 15 credits. GPA = 49.2 ÷ 15 = 3.28. With the AP bonus of 1.0 on the 4-credit course, the weighted GPA is (49.2 + 4) ÷ 15 = 3.55.

Weighted and unweighted GPA

Unweighted GPA treats every course the same, out of 4.0. Many US high schools also report a weighted GPA, which adds 0.5 for honors and 1.0 for AP or IB courses, so it can go above 4.0. Colleges often recalculate GPA their own way, so use both as a guide.

Frequently asked questions

How do I convert CGPA to percentage?

For CBSE, multiply the CGPA by 9.5: a CGPA of 8.4 is about 79.8%. Many universities publish their own formula, such as (CGPA − 0.75) × 10, so check your university's rules and enter its numbers. For (CGPA − 0.75) × 10, enter multiply by 10, then add −7.5.

Do pass/fail courses count?

Usually not. Leave them out, because they don't carry grade points.

What's the difference between GPA and CGPA?

GPA is usually for one term. Cumulative GPA (CGPA) averages every term so far, weighted by credits.
