How to Calculate CGPA (With Formula & Examples)

A complete guide on calculating your CGPA from SGPA and credits, complete with mathematical formulas and real-world examples.

The CGPA Formula

To calculate your CGPA, you cannot simply average your SGPAs. You must calculate the weighted average based on the number of credits completed in each semester.

CGPA = (SGPA₁ × Credits₁ + SGPA₂ × Credits₂ + ... + SGPAₙ × Creditsₙ) / (Total Credits)

Step-by-Step Example

Let's say you have completed two semesters:

  • Semester 1: SGPA = 8.5, Total Credits = 20
  • Semester 2: SGPA = 9.0, Total Credits = 22

1. Multiply SGPA by Credits for each semester:

  • Sem 1: 8.5 × 20 = 170
  • Sem 2: 9.0 × 22 = 198

2. Sum the values and divide by total credits (20 + 22 = 42):

(170 + 198) / 42 = 368 / 42 = 8.76 CGPA

Frequently Asked Questions

Everything you need to know about calculating and converting your grades.

What is a CGPA Calculator?

A CGPA Calculator is a tool used to calculate your Cumulative Grade Point Average based on semester grades, subject grades, and credits. It helps students track academic performance and estimate overall results.

How do I calculate CGPA?

CGPA is calculated by dividing the total weighted grade points earned by the total credits completed.

Formula:

CGPA = Total Grade Points ÷ Total Credits

The calculator automatically performs this calculation when you enter grades and credits.

How to Calculate CGPA from SGPA?

Enter your semester SGPAs and the corresponding credits for each semester. The calculator will compute the weighted average and generate your cumulative CGPA.

How to Convert SGPA into CGPA?

CGPA is usually calculated by taking the weighted average of all semester SGPAs based on credit values.

Use the SGPA to CGPA Calculator to perform this automatically.

How to Convert CGPA to Percentage?

Many universities use a conversion formula to estimate percentage from CGPA.

A common formula is:

Percentage = CGPA × 10

However, some universities use different formulas, so always check your university regulations or use our CGPA to Percentage Calculator.

How to Convert Percentage to CGPA?

Percentage can be converted into CGPA using your university's approved conversion formula.

For example:

CGPA = Percentage ÷ 10

Some universities may use different conversion factors.

Use the Percentage to CGPA Calculator for accurate results.

How to Convert CGPA into Marks?

There is no universal formula to convert CGPA directly into marks.

Marks depend on:

  • University regulations
  • Grading system
  • Credit structure

The Marks to CGPA Calculator provides estimated results where official conversion formulas are unavailable.

What is the Multiplying Factor in CGPA Calculation?

The multiplying factor is the number used by a university to convert CGPA into percentage.

Examples:

  • 10
  • 9.5
  • 9.25
  • Other university-specific values

The multiplying factor varies between institutions.

What is 75% as CGPA?

Using the common conversion formula:

CGPA = Percentage ÷ 10

75% is approximately:

CGPA = 7.5

The exact value may differ depending on university regulations.

What is a 3.0 GPA in CGPA?

A 3.0 GPA on a 4-point scale is approximately:

7.5 CGPA on a 10-point scale

The exact conversion depends on the grading system being used.

Use the GPA to CGPA Calculator for precise conversion.

Is CGPA More Important Than Percentage?

Both are important. Many universities and employers accept CGPA directly, while some convert CGPA into percentage during admissions or recruitment processes.

Can I Calculate CGPA Without Credits?

For accurate results, credits should always be included. Ignoring credits can produce incorrect CGPA values because most universities use credit-weighted calculations.
