Add your courses, credits and grades to get a live weighted GPA (4.0 scale) or CGPA (10-point) — with a built-in CGPA to percentage converter, right in your browser.
Grading scale
Your GPA
3.63/ 4.0
Based on 3 courses and 10 total credits.
Widely-used approximation: percentage = CGPA × 9.5. Individual universities may use their own formula, so treat this as an estimate.

Choose your grading scale
Toggle between GPA (4.0 scale, used across US colleges and universities) and CGPA (10-point scale, common in Indian universities and technical boards). The grade options and input fields change automatically to match.
Add a course
Enter a course name for your reference, type the number of credits (or credit hours) the course carries, and select the grade you received. Courses with more credits carry proportionally more weight in the final average.
Add all your courses
Click Add course to include every subject from your semester or entire programme. Your cumulative GPA or CGPA updates live at the top as you add, edit or remove entries.
Review your weighted average
The calculator displays your overall GPA or CGPA prominently. It is a credit-weighted average, not a simple mean — so a five-credit core subject moves your score five times more than a one-credit elective.
Use the CGPA to percentage converter
When using the CGPA (10-point) scale, type your CGPA into the converter box to see the approximate percentage using the widely-used CBSE formula: percentage = CGPA × 9.5.
Start over or edit as needed
Clear all courses to calculate a fresh set, modify individual entries to see hypothetical what-if scenarios, or adjust a grade to find out what you need in remaining courses to hit a target CGPA.
Planning your semester or academic year
Add your expected or target grades to forecast what GPA you will land if you score certain marks in each subject. It takes the uncertainty out of academic planning.
Verifying your transcript or mark sheet
Enter your actual grades from an official transcript to double-check your university's calculation. Spotting an error early can save weeks of administrative back-and-forth later.
Setting targets for remaining courses
Enter the grades you already have, then experiment with different grades for your remaining subjects to see exactly what you need to reach a target CGPA — useful before final exams or placement season.
GPA and CGPA are credit-weighted averages, not simple arithmetic means. For each course, the grade point (for example, A = 4.0, B = 3.0 on the 4.0 scale, or a numerical value on the 10-point scale) is multiplied by the number of credits the course carries. All these products are summed across every course you enter, then the total is divided by the sum of all credits. A 5-credit course therefore has five times the influence on your average compared to a 1-credit elective.

Your GPA is a credit-weighted average of your grade points. Each course's grade point is multiplied by its number of credits, those products are added up, and the total is divided by the total credits. Courses worth more credits therefore influence the result more than lighter ones.
GPA usually refers to a single term or semester on a 4.0 scale, common in the US. CGPA (Cumulative Grade Point Average) is the average across all terms, and in India it is normally reported on a 10-point scale. This tool supports both scales with a single toggle.
The most widely used approximation in India is percentage = CGPA × 9.5. For example, a CGPA of 8.0 works out to 76%. It is only an estimate — universities such as different state and central boards may publish their own conversion formula, so always check your institution's official method.
On the 4.0 scale this tool uses the common unweighted mapping: A and A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, and so on down to F = 0.0. On the 10-point scale you enter the grade point (0 to 10) your university awarded for each subject.
No. Every calculation happens in your browser with JavaScript. Your courses, credits and grades are never sent to a server, stored or seen by anyone, so it is safe to use for real transcripts.
This calculator gives you the cumulative GPA or CGPA for all courses you enter. To calculate a single semester's SGPA, enter only that semester's courses, note the result, and then clear before entering the next semester.
On the 10-point CGPA scale, you enter the numerical grade point directly — any value from 0 to 10 — so you can match your university's exact grading scheme. On the 4.0 scale, the tool uses the standard unweighted letter-grade mapping, which works for most institutions.
