Marks to SGPA Calculator
Type this semester's raw marks and the tool works out each grade for you, then shows your SGPA with a grade distribution so you can see how consistent the semester really was.
Quick answer: To convert marks to SGPA, turn each subject's marks into a percentage, find its grade point from your grade bands, then take the credit-weighted average. Marks of 82, 91, 68, 74, 88 and 95 across six 4-credit subjects give grade points 9, 10, 7, 8, 9, 10 and an SGPA of 8.83.

Grade distribution this semester
how many subjects landed in each bandEach subject: marks → percentage → grade (via cutoffs) → grade point. Then: SGPA = Σ (Grade Point × Credits) / Σ Credits
The step most SGPA calculators skip
Almost every SGPA calculator asks for grades you may not have yet. Many students only get raw marks back and have to look up the letter themselves before they can even start. This tool does that lookup subject by subject.
| Marks (%) | Grade | Grade point |
|---|---|---|
| 90–100 | O | 10 |
| 80–89 | A+ | 9 |
| 70–79 | A | 8 |
| 60–69 | B+ | 7 |
| 50–59 | B | 6 |
| 45–49 | C | 5 |
| 40–44 | P | 4 |
| Below 40 | F | 0 |
These are the common bands for the 10-point scale. Some departments draw them differently, so trust the grade printed on your marksheet if it disagrees.
Worked example
Priya scores 82, 91, 68, 74, 88 and 95 out of 100 in six subjects of 4 credits each.
| Marks | Grade | Grade point | Points × 4 credits |
|---|---|---|---|
| 82 | A+ | 9 | 36 |
| 91 | O | 10 | 40 |
| 68 | B+ | 7 | 28 |
| 74 | A | 8 | 32 |
| 88 | A+ | 9 | 36 |
| 95 | O | 10 | 40 |
Total = 212 points over 24 credits, so SGPA = 8.83. The distribution shows two O grades, two A+ and one A against a single B+, so this was a consistently strong semester, not one propped up by a single outlier.
One number can hide a very uneven semester
Two students can post an identical SGPA, one from six steady B+ grades and the other from three O grades and three near-fails balancing out. The average says nothing about which semester you had, and that matters for deciding what to fix.
| Pattern | What it suggests |
|---|---|
| Grades clustered in one or two bands | Consistent performance across subjects |
| Grades spread widely, some very high and some low | An uneven semester: strong in some subjects, struggling in others |
| One clear outlier dragging a strong spread | A single subject, not overall effort, is the thing to address |
Using it well
Set the total before entering marks
If your papers were out of 75 or 150, change the "out of" box first. Every percentage and grade lookup depends on it.
Different totals in one semester
The "out of" value applies to every row. If subjects have different totals, convert each to a percentage yourself and enter 100 as the shared total.
Percentage-based universities
Where marks already are the percentage, as in the UK, there is no grade-point step. The tool credit-weights the marks directly into one average.
Looking at your whole degree?
This tool covers one term. The SGPA to CGPA calculator shows how your grades have moved across every semester.
Frequently asked questions
How do I calculate SGPA from marks?
Convert each subject's marks to a percentage, find the grade point from your grade bands, multiply by credits, add them up and divide by total credits.
What if my marks are out of 75 or 150?
Change the "out of" field first. The tool converts to a percentage internally, so the grade lookup stays accurate.
Why does the same SGPA have a different distribution for different students?
SGPA is only the credit-weighted average, so many different grade combinations produce the same number. The distribution shows the mix behind it.
Is an uneven distribution a problem if the SGPA is fine?
Not for this semester's number, but a subject that pulled unusually low often has a fixable cause worth addressing before it repeats.
How accurate are the mark-to-grade cut-offs?
They follow the common convention for each scale. Departments can set their own boundaries, particularly near a borderline mark, so treat the result as a strong estimate.
Does this work for percentage-based universities like the UK?
Yes, without a grade lookup. Marks already are the percentage, so they are credit-weighted into a single semester average.
