About this tool
Programmes graded on the IGNOU five point scale do not convert linearly into a percentage. This converter applies the published cubic polynomial so the figure you quote on an application or a higher study form matches the value derived from the university formula rather than a rough multiplication.
How it works
Using the 5-Point CGPA to Percentage Converter in three steps
Every step below reflects the actual calculation this tool runs, so you can check the result by hand if you need to.
- 1
Enter the CGPA from your IGNOU five point scale grade card.
- 2
The non linear polynomial published for the five point scale is applied to that value.
- 3
The equivalent percentage is returned with the polynomial shown, so the figure is verifiable.

Five point scale polynomial
Percentage = 62.5 + 99.167(CGPA) - 30(CGPA)^2 + 3.333(CGPA)^3- The scale runs from 1.0 at grade E to 5.0 at grade A.
- The relationship is a curve, so multiplying the CGPA by twenty gives the wrong answer.
- Results are clamped between zero and one hundred percent.
Frequently asked questions
Why is the conversion not linear?
The five point scale compresses the higher grade bands, so a cubic polynomial is used to map grade points onto the percentage range accurately.
Which CGPA should I enter?
Use the cumulative grade point average printed on your grade card, not a single course grade.
Why is the conversion not linear?
The five point scale compresses higher grades, so a polynomial is used to keep the percentage equivalence realistic across the range.
Does this apply to ten point programmes?
No. Use it only where your grade card reports CGPA on the five point scale of A to E.
