About SGPA to CGPA Calculator
This SGPA to CGPA calculator combines your semester GPAs into one cumulative CGPA, weighting each semester by its credits. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
The page opens with the previous CGPA fields showing. Enter the CGPA so far and the credits it covers, add this semester courses, and the new cumulative CGPA appears. If you only know each semester SGPA, add one row per semester, enter that semester credits, pick Type point and enter the SGPA as the grade point.
Do not average SGPAs unless every semester carries the same credits. A 21-credit semester should count more than a 9-credit one, and the weighted result reflects that.
How to use SGPA to CGPA Calculator
- Choose your grading scale from the list. The table of letters and points for that scale is used for every course row. Pick Custom scale if your university uses its own table.
- Enter each course with its credit hours and grade. Choose a letter from the list, or pick Type point to enter a grade point yourself.
- Add or remove rows until the list matches your semester. Credits can be decimals such as 1.5.
- To get a cumulative result, switch on Add previous CGPA and enter your CGPA so far and the credits it covers. The new CGPA weights both by credit.
- Read the term GPA, the cumulative CGPA, the degree class where the scale has one, and the percentage, German grade and US 4.0 estimate.
- Use the target planner to enter the CGPA you want and the credits you have left. It shows the average you need.
Features
- Credit-weighted CGPA that updates on every keystroke, with no submit button.
- Nine scale options: Bangladesh UGC 4.00, a common private-university scale, US 4.0, US 4.3, India 10-point, ECTS, UK percentage, Bangladesh SSC/HSC 5.00 and a custom scale.
- A custom scale editor for the letters, points, top grade and lowest pass of your own university.
- Previous CGPA and completed credits, so a new semester updates your cumulative result.
- Degree class where the scale defines one, such as First, Second and Third class on the UGC scale, Latin honors on US 4.0, or UK honours bands.
- CGPA to percentage with the formula that fits the scale: grade band, linear, CBSE 9.5, times 10, or your own multiplier.
- Percentage to CGPA, the reverse conversion, with the same formula choices.
- German grade by the modified Bavarian formula, with three rounding modes: cut after one decimal, round to one decimal, or nearest German grade step.
- A US 4.0 estimate for scales that are not already 4.0, and a target CGPA planner.
SGPA to CGPA
Weight each semester GPA by its credits, add them up and divide by the total credits.
CGPA = Σ(SGPA × semester credits) ÷ Σ semester creditsWorked examples
Semester 1: SGPA 3.40, 15 credits. Semester 2: SGPA 3.70, 18 credits gives CGPA = (3.40 × 15 + 3.70 × 18) ÷ 33 = 3.56
A plain average would give 3.55.
Privacy: how it works
- Courses, credits and grades are handled by code running in your browser tab. Nothing is sent to Ulkaa or anyone else, and nothing is saved: closing the tab clears what you typed.
Tips
- Use the credit hours from your transcript, not the number of courses. A 1-credit lab counts a third as much as a 3-credit lecture.
- To enter a whole semester you only know as a GPA, add one row with that semester credits and choose Type point for its grade point.
- For a conversion to percentage, check which formula your university or the receiving organisation accepts before you quote the number.

How do I calculate CGPA from SGPA?
Multiply each SGPA by that semester credits, add the results and divide by the total credits of all semesters.
Is CGPA the average of all SGPAs?
Only when every semester has the same credits. Otherwise the credit-weighted figure is the correct one.
What if one semester has a retake?
Follow your university rule. If the new grade replaces the old, remove the old course. If both count, keep both.
