Choosing the Right CGPA Calculator
Not every university calculates CGPA the same way. A grade of "A" might equal 4.00 at one institution and 3.75 at another, and some countries use entirely different scales — 5.0, 7.0, or 10.0 — instead of the common 4.0 system. Using a calculator built for the wrong scale will give you an inaccurate CGPA, which matters when you're applying for scholarships, jobs, or graduate programs.
That's why this site offers a dedicated calculator for each major grading system, listed above. Pick the one that matches your official transcript, and you'll get an accurate, credit-weighted CGPA with multi-semester tracking, SGPA conversion, a target CGPA planner, and a downloadable PDF report — all for free.
