SGPA Calculator
Add your subjects with credits and grade points to instantly calculate your Semester Grade Point Average.
Your Semester Grade Point Average (SGPA) is the credit-weighted average of the grade points you score across every subject in a semester — not a simple average, since subjects with more credits count for more. This SGPA calculator is built for Indian university and college students who want an exact, instant result without doing the weighted-average math by hand each semester. Add each of your subjects with its credits and grade point (or pick a letter grade from the standard 10-point mapping), and your SGPA updates live as you type. Most Indian universities use a 10-point grading scale, but since some institutions use a different maximum, this tool also supports a fully custom scale. Nothing you enter is sent anywhere or stored — all calculations run entirely in your browser.
Worked Example
Say a student has three subjects in a semester, graded on the 10-point scale:
| Subject | Credits | Grade Point | Credits × GP |
|---|---|---|---|
| Data Structures | 4 | 9 | 36 |
| Mathematics | 3 | 8 | 24 |
| English | 2 | 7 | 14 |
Total credits: 4 + 3 + 2 = 9. Total weighted points: 36 + 24 + 14 = 74. SGPA = 74 ÷ 9 = 8.22. These exact numbers are pre-filled in the calculator below so you can see the live result immediately.

How to Use This Calculator
- Select your grading scale. Choose 10-Point Scale (the default, used by most Indian universities) or Custom Scale if your university uses a different maximum grade point, like a 4-point scale.
- Add each subject using the "+ Add Subject" button, or edit the pre-filled example rows to match your own semester.
- Enter credits and grade point for every subject. On the 10-point scale, you can either type the grade point directly or pick a letter grade (O, A+, A, B+, B, C, P, F) from the dropdown to auto-fill it.
- Your SGPA calculates instantly in the result card above, along with a full per-subject breakdown showing each subject's weighted contribution.
- Add or remove subjects as needed — the calculator recalculates live every time you change a value, add a row, or remove one.
What SGPA Means and Why Credits Matter
SGPA (Semester Grade Point Average) summarizes how you performed across every subject in one semester, weighted by each subject's credit value. It's calculated as the sum of (credits × grade point) for every subject, divided by the sum of all credits — a weighted average, not a plain average of grade points. This matters because not all subjects carry equal weight in your curriculum: a 4-credit core subject or lab course influences your SGPA more than a 1-credit elective, so scoring well in higher-credit subjects has a bigger impact on your final number.
SGPA is often confused with CGPA, but they measure different spans of time. SGPA reflects a single semester, while CGPA (Cumulative Grade Point Average) is the credit-weighted average across all semesters completed so far in your program — essentially, your CGPA is built up from your SGPAs each semester. Once you know your semester or cumulative grade point average, you can convert it to a percentage using CareerShuru's CGPA to Percentage Calculator, which supports the specific formulas used by VTU, Anna University, Mumbai University, CBSE, DU and more.
One important caveat: there's no single national grading scale in India. Most universities following AICTE/UGC-aligned norms use a 10-point scale, but some institutions use a 4-point scale or other variations entirely. Always confirm your own university's exact grading scale and letter-grade mapping from your official grade card or academic handbook — this calculator's 10-point letter-grade reference is a common default, not a universal standard, which is why a Custom Scale option is included.
Frequently Asked Questions
What is SGPA?
SGPA (Semester Grade Point Average) is the credit-weighted average of the grade points you earn across all subjects in a single semester. Each subject's grade point is multiplied by its credits, those products are summed, and the total is divided by the sum of all credits — so subjects with more credits (typically core or lab-heavy subjects) influence your SGPA more than lower-credit subjects.
How is SGPA different from CGPA?
SGPA measures your performance in one semester only, while CGPA (Cumulative Grade Point Average) is the credit-weighted average across all semesters completed so far. Your CGPA is typically calculated by averaging your SGPAs across semesters, weighted by each semester's total credits. Once you have your SGPA for each semester, you can convert your overall CGPA to a percentage using CareerShuru's CGPA to Percentage Calculator.
What is considered a good SGPA?
On the common 10-point scale, an SGPA of 8 and above is generally considered strong, 6.5-8 is decent and competitive for most placements, and below 6 may limit eligibility for some campus placement drives or higher-education applications. That said, "good" is relative to your university's grading distribution and your target companies' or institutes' specific cutoffs — always check the exact eligibility criteria you're aiming for rather than relying on a general benchmark.
Does SGPA affect campus placements?
Individual semester SGPA is usually less important than your overall CGPA for placement eligibility, since most companies set a minimum CGPA cutoff (commonly 60-65% equivalent, or roughly 6-6.5 on a 10-point scale) rather than screening semester-by-semester. However, a very poor SGPA in one semester can drag down your CGPA enough to affect that cutoff, so consistent performance across semesters matters more than any single semester in isolation.
Can SGPA be more than 10?
No, not on a standard 10-point scale — SGPA is a weighted average of grade points, and if every individual subject's grade point is capped at 10, the weighted average can never exceed 10 either. If you're using a custom scale (e.g. a 4-point scale used by some universities), the same logic applies: your SGPA cannot exceed your scale's maximum grade point, since it's an average, not a sum.
How do I convert my SGPA or CGPA to a percentage?
The formula depends on your university — common ones include Percentage = CGPA × 9.5 (CBSE/DU-style) or Percentage = (CGPA − 0.75) × 10 (VTU/Anna University-style). Use CareerShuru's dedicated CGPA to Percentage Calculator, which supports multiple official university formulas, once you've worked out your SGPA or overall CGPA here.
Why do different universities use different grading scales?
Each university or affiliating board sets its own grading policy — most Indian universities following AICTE/UGC-aligned norms use a 10-point scale, but some institutions (particularly those following certain international or older systems) use a 4-point scale or other variations. Because there's no single national standard, this calculator lets you choose the 10-point scale or enter your own university's maximum grade point under Custom Scale, so the SGPA math stays correct regardless of which scale your institution uses.
Does this calculator use official letter-grade to grade-point mappings?
It includes the most common 10-point letter-grade mapping used across many Indian universities (O=10, A+=9, A=8, B+=7, B=6, C=5, P=4, F=0) as a quick-select option per subject, but this mapping isn't universal — some universities use slightly different letter grades or point values. If your university's grading sheet shows a different mapping, simply enter the grade point directly instead of using the letter-grade dropdown; the calculator computes correctly either way.
