How to use the Backlog Impact on CGPA Calculator
- 1. Enter your CGPAType your current CGPA and the credits counted in it.
- 2. Pick the rule and list backlogsChoose how failed subjects count, then add each backlog's credits and expected grade point.
- 3. See the new CGPAGet the CGPA after clearing all backlogs, each one alone, and at the pass grade.
Two ways universities count a failed subject
Rule 1: counted at 0. The failed subject's credits are in your CGPA with 0 grade points. When you clear it, the new grade replaces the 0. New CGPA = (current CGPA × credits + sum of new grade point × backlog credits) ÷ credits.
Rule 2: left out until cleared. The failed credits are not in your CGPA yet. When you clear them, both the points and the credits are added. New CGPA = (current CGPA × credits + sum of new grade point × backlog credits) ÷ (credits + backlog credits).
Worked example with the defaults (rule 1): CGPA 6.8 over 120 credits gives 816 points. Clearing Maths III (4 credits) with a 6 adds 24, and DBMS (3 credits) with a 7 adds 21. Now 861 ÷ 120 = 7.18.
Check your university's rule
Universities handle backlogs in many ways. Some cap the grade you can get in a re-exam, some show both attempts on the transcript, and some count only the latest attempt. Read your ordinance and set the grade points to match. The tool also shows the CGPA if every backlog is cleared at the lowest pass grade, which is a safe planning figure.
To check whether your backlogs allow promotion, use the backlog eligibility calculator. To plan study time, try the backlog clearing planner.
Frequently asked questions
Which rule does my university use?
Look at the CGPA rules in your university's ordinance or ask the exam cell. Your marksheet may also show whether F-grade credits are counted.
What grade should I enter?
Enter the grade point you expect. If you are unsure, the pass-grade figure shows the minimum gain.
Can a backlog lower my CGPA after I clear it?
Under rule 2, clearing with a grade below your current CGPA lowers the average slightly, but you earn the credits you need for the degree.
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.
