SGPA to CGPA Calculator – Convert SGPA to CGPA Online
Figuring out your CGPA from SGPA gets messy once you have scores from several semesters. Enter your semester SGPAs below — with credits if you know them — and get your overall CGPA in seconds.

Tip: leave every Credits field blank for a quick simple average, or fill them all in for the exact credit-weighted result your university uses.
What Is SGPA and CGPA?
SGPA stands for Semester Grade Point Average. It sums up how you did in one single semester, usually on a 10-point scale. Your college works it out from the grades and credits of the subjects you took that term. A higher SGPA simply means a stronger semester.
CGPA stands for Cumulative Grade Point Average. It zooms out and covers your whole degree so far. Say your SGPAs came in as 8.0, then 7.5, then 8.2, then 8.6. Each of those is one semester’s story; your CGPA blends them into a single number using your university’s method.
The two are related the way chapters relate to a book. SGPA tells you how one chapter went. CGPA tells you how the book reads overall — which is why placements, scholarships, and admissions offices almost always ask for the CGPA.
How to Convert SGPA to CGPA
Whether you use the online SGPA to CGPA calculator above or do it by hand, the process is the same. Here’s the exact sequence:
- Collect every SGPA. Pull the SGPA of each finished semester from your grade cards — all of them, not just the good ones.
- Note the credits per semester (only if your university weights by credits — VTU, Mumbai University, and Anna University do). Skip this step for a simple average.
- Run the numbers. Type the SGPAs into the calculator and hit Calculate CGPA, or apply the formula in the next section manually.
- Sanity-check the result. Compare it against your university’s official method before putting it on any application — a two-minute check that saves real embarrassment later.
SGPA to CGPA Formula
There are two versions in common use. Pick the one your university follows:
Simple average (equal weight per semester)
CGPA = (SGPA₁ + SGPA₂ + … + SGPAₙ) ÷ n
Credit-weighted (most Indian universities)
CGPA = Σ(SGPA × credits) ÷ Σ(credits)
📘 Note: the exact CGPA calculation method varies by university and sometimes by batch or regulation. Your handbook or grade card always has the final word.
Worked Example: SGPA to CGPA Calculation
Let’s take a student with four semesters done. Here are the marks straight off the grade cards:
| Semester | SGPA | Credits | SGPA × Credits |
|---|---|---|---|
| Semester 1 | 8.2 | 20 | 164.0 |
| Semester 2 | 7.8 | 22 | 171.6 |
| Semester 3 | 8.5 | 20 | 170.0 |
| Semester 4 | 8.0 | 24 | 192.0 |
| Total | 32.5 | 86 | 697.6 |
Credit-weighted: 697.6 ÷ 86 = 8.11 CGPA.
Simple average, for comparison: (8.2 + 7.8 + 8.5 + 8.0) ÷ 4 = 32.5 ÷ 4 =8.13 CGPA. Close — but not identical. That small gap is exactly why credit-heavy semesters deserve their proper weight.
Can You Convert CGPA Back to SGPA?
Short answer: not exactly. One CGPA can arise from countless SGPA combinations, so there is no unique reverse conversion — a “CGPA to SGPA calculator” can only estimate.
The one exception: if you know everything except a single semester. Under a simple-average system, rearrange the formula:
Missing SGPA = (CGPA × n) − sum of known SGPAs
Example: CGPA 8.0 after 4 semesters, with known SGPAs of 7.8, 8.2, and 8.0 gives (8.0 × 4) − 24.0 = 8.0 for the missing term. Under credit weighting you need that semester’s credits too — same idea, slightly longer arithmetic.
CGPA to Percentage Conversion
Job forms and scholarship portals usually want a percentage, not a CGPA. The most widely quoted shortcut in India is the CBSE-style estimate:
Percentage = CGPA × 9.5
Using our worked example: 8.11 × 9.5 = 77.05%. Handy — but treat it as an estimate unless your university prints the same formula. VTU, Mumbai University, and Anna University each publish their own (see the university table below), and those official versions always win.
Difference Between SGPA and CGPA
Students mix these up constantly, so here’s the SGPA vs CGPA split in one glance:
| Aspect | SGPA | CGPA |
|---|---|---|
| Full form | Semester Grade Point Average | Cumulative Grade Point Average |
| Scope | One single semester | Your whole degree so far |
| Purpose | Shows how one term went | Shows your overall standing |
| How it changes | Can swing a lot between semesters | Moves slowly as semesters pile up |
| Used for | Semester review, backlogs, course correction | Placements, higher studies, scholarships |
Put simply: SGPA = how one semester went. CGPA = how your degree is going.
How Different Universities Calculate CGPA
This is where most students go wrong: they borrow a friend’s formula from another university. The table below covers the methods most commonly published — but regulations change by batch, so treat your handbook as the final authority:
| University | Usual CGPA method | Percentage formula often used |
|---|---|---|
| VTU | Credit-weighted across semesters | (CGPA − 0.75) × 10 (older schemes; newer batches may differ) |
| Mumbai University | Credit-weighted, 10-point CBCS | 7.1 × CGPA + 11 |
| Anna University | Credit-weighted | CGPA × 10 |
| CBSE-pattern / DU colleges | Follows board practice | CGPA × 9.5 |
⚠️ Costly mistake to avoid: an 8.0 CGPA is 76% under ×9.5 but only about 72.5% under VTU’s formula. Always convert with your university’s formula on official paperwork.
Common Mistakes to Avoid
- Averaging when you should be weighting. If your semesters carry different credits, a flat average quietly misreports your CGPA. Enter the credits and let the weighted method do its job.
- Mixing up grading scales. A 10-point SGPA, a 4-point GPA, and a percentage are three different languages. Convert between them only with your university’s official mapping.
- Using ×9.5 everywhere. It’s the most quoted percentage shortcut, but VTU, Mumbai University, and several others officially use something else.
- Skipping the official guidelines. Regulations change between batches and schemes. A five-minute check of your handbook beats redoing an application.
FAQ
Frequently Asked Questions
Can I convert SGPA to CGPA?
Yes. If you have the SGPA of every completed semester and you know your university’s method, you can work out your overall CGPA. Enter the SGPAs above (credits too, if your university weights by credits) and the calculator does the rest.
How do I convert SGPA into CGPA?
Under a simple-average system, add all your semester SGPAs and divide by the number of semesters. Under a credit-weighted system, multiply each SGPA by its semester credits, add those up, and divide by total credits. The calculator above handles both.
Is CGPA just the average of all SGPA values?
Only when every semester carries equal weight. Many Indian universities (VTU, Mumbai University, Anna University) weight semesters by credits instead, so a flat average can be slightly off. When in doubt, use the weighted method.
Can I calculate CGPA without knowing my credits?
Yes — leave the Credits fields blank and you’ll get the simple average, which is a solid estimate. For the exact figure your university will print, grab the credit totals from your grade cards and enter those too.
Is SGPA the same as CGPA?
No. SGPA describes one semester; CGPA describes your cumulative record across semesters. Think of SGPA as the chapter score and CGPA as the book’s rating so far.
Which is higher, SGPA or CGPA?
Neither, necessarily — they measure different things. A great semester gives you a high SGPA, but your CGPA only climbs gradually because it averages your whole history, including weaker semesters.
Can I calculate CGPA from one SGPA?
With a single finished semester, that SGPA is effectively your CGPA so far (there’s nothing else to average yet). From semester two onward, you need every previous SGPA for a correct result.
Can I convert CGPA back to SGPA?
Not exactly — one CGPA can come from many different SGPA combinations, so the reverse isn’t unique. But if you know your CGPA, the number of semesters, and all the other SGPAs, you can solve for the missing one (explained above).
How do I convert CGPA to percentage?
It depends on your university. CBSE-pattern institutions commonly use Percentage = CGPA × 9.5, Anna University uses CGPA × 10, VTU uses (CGPA − 0.75) × 10, and Mumbai University uses 7.1 × CGPA + 11. Never assume — check your handbook.
