CGPA Calculator

Enter your semester GPAs and the credits for each semester, choose the 10-point or 4-point scale, and this calculator returns your CGPA, an equivalent percentage, total credits and your best semester. It is built for university students in India and other countries on a 10-point credit system, and also works for 4.0-scale cumulative GPAs.

The key point is weighting by credits. A heavy 26-credit semester should count more than a light 18-credit one; a plain average of SGPAs gives the wrong answer whenever credit loads differ. If your semesters all carry the same credits, the two methods match.

To calculate a single semester's GPA from course grades first, use the GPA calculator. Percentage conversions vary by university — the ×9.5 rule shown here is the most widely quoted, but your transcript or university regulations decide which formula applies to you.

This is a weighted mean, the method set out in the UGC Choice Based Credit System (CBCS) guidelines for Indian universities, where CGPA is computed from SGPAs weighted by semester credits. The ×9.5 factor comes from CBSE's school grading scheme; several universities publish their own conversion, such as (CGPA − 0.5) × 10 or (CGPA − 0.75) × 10, so check your regulations. The 4-point percentage here is a straight proportion; US colleges do not generally convert GPAs to percentages, so treat it as indicative only.

The UGC CBCS guidelines recommend this grade-point scale. Individual universities map marks to letters differently, so the marks ranges are set locally.

• SGPA (semester grade point average) is the credit-weighted average of course grade points within one semester.
• CGPA combines all semesters so far, weighted by the credits of each semester.
• GPA is the general term; on US transcripts, "cumulative GPA" is the same idea as CGPA on a 4.0 scale.
• Failed and repeated courses: in most systems a fail (0 points) stays in the credit total until you clear it, which drags the CGPA down. When you pass on a re-attempt, many universities replace the old grade — check whether yours averages both attempts.

For a weighted average of anything else, such as marks with different maximums, the weighted average calculator uses the same arithmetic.

The more credits you have completed, the less any single semester moves your CGPA. After 96 credits at 8.48, a 24-credit semester at 9.5 lifts the CGPA only to about 8.69. To reach a target, work backwards: target CGPA × (credits so far + new credits) − current CGPA × credits so far, divided by the new credits, is the SGPA you need. For example, going from 7.5 over 80 credits to 8.0 after 20 more credits needs an SGPA of 10.0 — so set realistic targets early in the degree. The percentage calculator helps when an application asks for marks as a percentage of a maximum.
