What Is the Multi-Subject CGPA Calculator?
The Multi-Subject CGPA Calculator is a free online tool that works out your overall Cumulative Grade Point Average (CGPA) across every subject in a semester or academic year. Instead of averaging your grades equally, it applies a credit-weighted CGPA formula โ so a 4-credit core subject counts for more than a 1-credit elective, exactly the way most colleges, universities and grading boards calculate it. Just tell it how many subjects you're taking, assign a letter grade (A+ through NG) and a credit value to each one, and it returns your combined CGPA instantly, without spreadsheets or manual grade-point math.
It's built for students who want to calculate CGPA online before results are officially published, plan how upcoming exams will affect their semester CGPA, or simply convert a mixed set of subject grades into one final number for a resume, scholarship application, or transcript check.
How to Use the CGPA Calculator
Type the total subjects for the semester into the Number of Subjects field โ the subject rows appear automatically, no page reload needed.
Credit hours reflect how much weight a subject carries โ check your course handbook or mark sheet if you're unsure of a subject's credit value.
Choose from A+, A, B+, B, C+, C, D, or NG (No Grade / Fail) โ each grade maps to a fixed grade point, shown right next to the dropdown.
Your total credits and final credit-weighted CGPA appear instantly below the form.
The CGPA Formula It Uses
Every subject's grade is converted to a grade point, multiplied by its credit hours, and the results are summed and divided by total credits:
| Grade | Grade Point |
|---|---|
| A+ | 4.0 |
| A | 3.6 |
| B+ | 3.2 |
| B | 2.8 |
| C+ | 2.4 |
| C | 2.0 |
| D | 1.6 |
| NG | 0.0 |
Grading scales vary by institution โ check your college's official scale if it differs from the one above.
Frequently Asked Questions
Common questions students ask about CGPA, credit weighting, and this calculator.
What is CGPA and how is it different from GPA?
GPA (Grade Point Average) usually refers to your grade average for a single semester or term. CGPA (Cumulative Grade Point Average) is the combined, credit-weighted average across multiple subjects โ or multiple semesters โ giving you one overall score for your entire course load.
Why does this CGPA calculator ask for credit hours?
Not every subject carries equal weight. A 4-credit core course affects your CGPA more than a 1-credit elective. Credit-weighted CGPA reflects that โ a high grade in a heavy-credit subject moves your overall CGPA more than the same grade in a light-credit one.
How many subjects can I add to the calculator?
You can calculate CGPA for up to 30 subjects in one go โ enough for a full semester or an entire academic year. Enter the number of subjects at the top of the tool and the rows are generated automatically.
What does the "NG" grade option mean?
NG stands for "No Grade" โ used for a subject that wasn't passed or wasn't graded. It carries a grade point of 0.0, so including it will lower your overall CGPA, the same way it would on an official transcript.
Does my grading scale match this calculator's?
This tool uses a common 4.0-point scale (A+ = 4.0 down to NG = 0.0). Some institutions use a 5.0 or 10.0 scale, or slightly different grade-point values โ check your college's grading policy and treat the result here as a close estimate rather than an official transcript figure.
Is this CGPA calculator free, and is my data stored anywhere?
Yes โ it's completely free, with no sign-up. All calculations happen directly in your browser, and no subject names, grades, or credits are sent to or stored on any server.
