How to convert CGPA to percentage

By the FreeAllTool team · Updated October 28, 2026

Many schools, boards and universities grade students on a 10-point CGPA scale, but job forms and admission portals often ask for a percentage. There is no single conversion formula that applies everywhere, so it is worth understanding the common methods and where to find the correct one for you.

CGPA, SGPA and GPA

SGPA is the grade point average for one semester. CGPA, the cumulative grade point average, combines all semesters, usually weighted by the credits of each course. Both are commonly on a 10-point scale in India.

The CBSE multiplier of 9.5

When CBSE used CGPA for Class 10, it indicated that an approximate percentage could be found by multiplying CGPA by 9.5. A CGPA of 8.4 therefore converts to about 8.4 × 9.5 = 79.8%. This applies to that CBSE system and should not be assumed for other boards or universities.

University formulas

Universities and autonomous institutions often publish their own formulas. Some multiply CGPA by 10. Others subtract a fixed value first, for example (CGPA − 0.75) × 10 or (CGPA − 0.5) × 10. The result for the same CGPA can differ by several percentage points depending on the formula.

How to find the correct formula

  1. Check the back of your mark sheet or grade card. Many institutions print the conversion formula there.
  2. Look at your university’s academic regulations or examination section on its official website.
  3. If an employer or admission body specifies its own method, use theirs.
  4. If nothing is stated, ask the examination office for a conversion certificate.

Calculating the percentage from marks

If your mark sheet shows raw marks, you can calculate your percentage directly: total marks obtained ÷ maximum marks × 100. Our percentage calculator does this instantly with the “X is what percent of Y” option.

Be consistent and honest

When a form asks for a percentage, mention the formula you used if there is space, and keep your grade card ready for verification. Using the official method avoids problems later.
