How to use the What-if SGPA Calculator
- 1. List your subjectsEnter each subject's name, credits and current grade point.
- 2. Add what-if gradesAdd a fourth number for any subject whose grade you want to change.
- 3. CompareSee the current and what-if SGPA, and the CGPA effect if you add your previous CGPA.
How a grade change affects SGPA
SGPA = sum of (grade point × credits) ÷ total credits. When one grade changes, the credit points change by (new grade point − old grade point) × that subject's credits. Divide that by the total credits to get the change in SGPA.
Worked example with the defaults: five subjects with 16 credits give 117 credit points, an SGPA of 7.31. Raising Maths (4 credits) from 7 to 8 adds 4 points, and Data Structures (4 credits) from 8 to 9 adds 4 more. Now 125 ÷ 16 = 7.81, a rise of 0.5.
Where to focus your effort
A one-point rise in a 4-credit subject moves SGPA twice as much as the same rise in a 2-credit lab. Use the tool to test where extra study gives the biggest gain, or how much a revaluation result or re-exam could change your SGPA.
Add your previous CGPA and its credits to see the CGPA before and after as well. Grade point tables differ by university, so enter the grade points printed on your marksheet. To calculate SGPA from letter grades, use the SGPA calculator. To turn marks into grades, use the marks to grade converter.
Frequently asked questions
Do I need a what-if grade for every subject?
No. Leave it out and that subject keeps its current grade.
Can I test a lower grade?
Yes. Enter a lower what-if grade point to see how much a bad result would cost.
Why does a lab grade change my SGPA so little?
Labs often carry fewer credits, and SGPA is weighted by credits.
Is this tool free?
Yes. You enter your name and WhatsApp number once when you see your result, and other Uncodemy tools then open without the form.
