SPI to CGPA Calculator
Enter your SPI and credits for each completed semester to get your cumulative CGPA — this calculation method is the same across universities.
Enter your SPI (semester performance index) and credit load for each completed semester. This calculation is the standard credit-weighted average used across universities, so it applies regardless of which college you're at.
How SPI to CGPA works
SPI (Semester Performance Index) measures your performance in a single semester, while CGPA (Cumulative Grade Point Average) is the credit-weighted average of every SPI you've earned so far. The formula is straightforward: multiply each semester's SPI by that semester's credit load, sum those values across all semesters, then divide by the total credits.
This method is standard across almost all Indian universities using the CBCS/CBCGS credit system, which is why — unlike CGPA-to-percentage conversion — it doesn't need a university-specific formula.
