How to Calculate CGPA Online Free
CGPA is your Cumulative Grade Point Average — the average of every semester so far, weighted by credits, so a heavy semester counts more than a light one. This guide shows how to calculate CGPA from your semester SGPAs and credits, on a 10-point or 4.0 scale, and how to convert it to a percentage. Use the free CGPA calculator below — it also converts CGPA to percentage.
How to Calculate CGPA — step by step
- Pick your grade scale — 10-point or 4.0 — then add a row for each semester and enter its SGPA and credits.
- Read your CGPA: it updates live as you change anything.
- To convert, enter your CGPA and pick the conversion formula.
- Read the percentage.
Tips
- Pick the right scale first — 10-point for O to F grading, 4.0 for A to F, or Custom if your university uses another scale.
- CGPA is weighted by credits: a 16-credit semester counts more than a 14-credit one, so enter the credits for every semester.
- To convert to a percentage, use the multiplier your university states — 9.5 under the CBSE formula, 10 at many other universities.
