How to Use the SGPA Calculator
Keep your grade card and course-credit list beside you. Enter all courses that your university includes in the semester calculation, not just the subjects with good grades.
- Set the maximum grade-point scale. The default is 10. Change it if your institution uses a different scale; this setting is not a grade converter.
- Add each course. Course names are optional, but names or codes make the breakdown easier to check.
- Enter credits and grade points. Use the official credit value and numerical grade point for that course. Do not enter raw marks.
- Adjust the rows. Use + Add course or the remove button. You can enter up to 20 courses. Rows with both numerical fields empty are ignored.
- Add earlier results if needed. Enter both your previous CGPA and its corresponding credit total, or leave both blank.
- Select Calculate SGPA. Check the SGPA, total credits, weighted points and individual course contributions.

What Is SGPA, and How Is It Calculated?
SGPA stands for Semester Grade Point Average. It summarises the grade points of the courses included in one semester, taking their credits into account. The number tells you your semester average; it does not, by itself, confirm that every course is passed.
Here, Σ means “add together.” First multiply each course’s credits by its grade point. Add those products, then divide by the combined credits. The result is a credit-weighted average, not an unweighted average.
This formula is described in section 7 of the UGC CBCS guidelines hosted by the University of Delhi. Use your own programme’s current regulations to decide which courses and grades belong in the calculation.
SGPA Formula with a Solved Example
Suppose a student has the following five courses on a 10-point scale. These are illustrative values, not a university’s prescribed curriculum or letter-grade mapping.
| Course | Credits | Grade point | Credits × points |
|---|---|---|---|
| Engineering Mathematics | 4 | 8 | 32 |
| Data Structures | 4 | 9 | 36 |
| Digital Electronics | 3 | 7 | 21 |
| Environmental Science | 2 | 10 | 20 |
| Data Structures Lab | 1 | 10 | 10 |
| Total | 14 | — | 119 |
- Add the weighted points: 32 + 36 + 21 + 20 + 10 = 119.
- Add the credits: 4 + 4 + 3 + 2 + 1 = 14.
- Divide: 119 ÷ 14 = 8.50 SGPA.
Select Use example above and then calculate to reproduce this result. The on-screen breakdown shows the same five products, so you can check each row rather than trust an unexplained total.
Why do course credits matter?
Ignoring credits changes this example to (8 + 9 + 7 + 10 + 10) ÷ 5 = 8.80. That is the simple average, not the correct credit-weighted result of 8.50.
A one-point improvement in the four-credit Mathematics course adds four weighted points; the same improvement in the one-credit lab adds one. Course titles do not decide the weight. Always use the listed credits, including those for practicals and projects.
How the Updated CGPA Estimate Works
If you already have a cumulative result, you do not need to re-enter every earlier subject. Supply the previous CGPA and the exact credit total represented by that CGPA. The calculator adds the current semester’s weighted points to the earlier total.
Using the example above, assume your previous CGPA was 8.20 across 90 credits. Your earlier weighted total is 8.20 × 90 = 738. Add 119 current points and 14 current credits:
Use compatible grades and the same scale throughout. If your previous credit total excludes courses that were counted in the CGPA, the estimate will be wrong. Previously rounded CGPA values can also introduce a small difference from the university’s calculation.
Why Use the OpenStudyInfo SGPA Calculator?
If you need to check both your semester average and its effect on your overall CGPA, this tool keeps those calculations together. Its practical advantage is the ability to inspect the inputs and calculation, not a claim that other calculators are inaccurate.
A visible breakdown
See each credit × grade-point product alongside the totals. This makes a mistyped credit value easier to spot than a single unexplained score.
SGPA and updated CGPA
Calculate this semester alone, or add the previous CGPA and credit total to estimate the combined result in the same form.
Adjustable inputs
Choose the maximum grade-point scale, enter decimal values and add or remove courses. Numerical entry avoids assuming one letter-grade mapping.
No account or upload
Enter course values directly. The calculator code runs in your browser and does not submit entries or create a saved results history.
The form also flags incomplete credit/grade pairs and grade points above the selected maximum. These checks catch input problems; they cannot confirm that you selected your university’s correct grading rule.
Know the limits: there is no automatic marksheet reading, university selection, letter-grade lookup or PDF export. Copy result provides a text summary, not a downloadable transcript. A tool with verified university-specific presets may be more convenient if you need those features.
SGPA, CGPA and Percentage: What Changes?
| Measure | What it covers | What you need |
|---|---|---|
| SGPA | Included courses in one semester | Course credits and grade points |
| CGPA | Cumulative performance across included study periods | Compatible weighted points and credits |
| Percentage | A result expressed out of 100 | Applicable marks calculation or an authorised conversion rule |
Do not average semester SGPAs without checking their credit totals. For example, 8.00 across 20 credits and 9.00 across 30 credits combine to (160 + 270) ÷ 50 = 8.60, not 8.50.
Can SGPA be converted to percentage?
Check your institution’s published conversion rule. Do not assume that multiplying by 9.5, multiplying by 10 or subtracting a fixed amount works for your programme. Also check whether the rule applies to semester SGPA or only to final CGPA.
Once you have the applicable rule for a CGPA conversion, use the CGPA to percentage converter with the matching method. Do not enter a converted percentage on an application form until you have checked what the receiving institution asks for.
Where to Find Course Credits and Grade Points
Start with the official semester grade card. Check the credit column, grade-point column and any legend explaining letter grades. If credits are missing, consult the approved syllabus or programme structure for your batch, including the practical and elective sections.
Marks, letter grades and grade points are different inputs. A score of 78/100 does not automatically mean 7.8 grade points. Likewise, an “A” copied from another university’s table may have the wrong numerical value.
For programmes evaluated through assignment and term-end marks, use the IGNOU marks and percentage calculator when its calculation method matches your programme. Do not force marks-based results into an SGPA calculation merely because the course has credits.
Failed, Absent, Audit and Zero-Credit Courses
Course inclusion matters as much as the arithmetic. Check the examination rules applicable to your programme and admission batch before removing any course.
- Failed or absent: if the rule includes the course with zero grade points, retain its credits and enter 0. The UGC CBCS guideline’s recommended grade table assigns zero to F and Ab; check your institution’s implementation.
- Pending results: do not treat an unpublished grade as a confirmed zero. A calculation using assumed grades is only a scenario.
- Audit and non-credit work: confirm whether it contributes to the average. Exclude it when your regulations exclude it. Do not give a zero-credit course invented credits to make the form accept it.
- Improvement or repeat attempts: verify which attempt counts and whether an earlier result is revised. Do not count the same course twice without a rule requiring it.
This calculator requires positive credits for each included row. If the correct treatment is unclear, ask your examination office which credits and grade points should enter the numerator and denominator.
Common Mistakes to Avoid
- Ignoring unequal credits: a simple average can overstate or understate the result.
- Entering marks: obtain the official numerical grade point first.
- Missing practicals: include labs, projects and electives whenever the rules count them.
- Mixing scales: a 4-point CGPA cannot be combined directly with 10-point course grades.
- Dropping inconvenient results: a failed course cannot be excluded just to improve the average.
- Using the wrong previous credits: enter the denominator behind the earlier CGPA, not a guessed total or the full degree requirement.
- Rounding too soon: retain the available precision in intermediate products. The calculator displays the final average to two decimal places.
How to verify your calculated SGPA
Compare the course list, credit total and grade points with your grade card. Recheck any missing lab, repeated course or excluded credit. If the inputs agree but the result differs, ask about rounding and course-inclusion rules before assuming the university made an error.
For planning, change one grade point at a time and recalculate to see its effect. Keep hypothetical grades separate from your official results. You can then use the study timetable generator to organise revision around the subjects needing attention.

Frequently Asked Questions
How does this SGPA Calculator work?
It multiplies each included course’s credits by its grade point, adds the products and divides by the total credits. You can check both totals and the course-wise breakdown after calculating.
Can I enter marks or letter grades directly?
No. Enter the numerical grade point assigned under your university’s rules. A mark such as 78 out of 100 is not automatically a grade point of 7.8, and the same letter grade can mean different points in different grading systems.
Is SGPA the simple average of all subject grade points?
Only when every included course has the same credit value will the simple and credit-weighted averages match. If credits differ, multiply each grade point by its credits before calculating the average.
Can I estimate an updated CGPA with this tool?
Yes. Enter the previous CGPA and the exact credit total used to calculate it. The calculator combines those earlier weighted points with the current semester. Use the same grading scale, avoid double-counting courses and treat the result as an estimate.
Can I convert SGPA directly into percentage?
Use a conversion only when your institution publishes an applicable rule. Check whether that rule applies to semester SGPA or final CGPA, and to your programme and batch. This calculator does not automatically convert the result into percentage.
Should I include a failed or absent subject?
Follow your university’s rules. If an included failed or absent course carries zero grade points, enter its actual credits and 0 as the grade point. Do not leave a required course out simply because it lowers the result. Pending marks are not automatically a zero.
Where can I find credits and grade points?
Start with your official grade card and the programme’s approved syllabus or curriculum. Check the grading legend and credit column. If either is missing, consult your examination office instead of borrowing values from another programme.
Can I use a 4-point scale or enter decimal values?
Yes. Change Maximum grade-point scale to the value used by your institution, then enter compatible numerical grade points and positive credits. Decimal inputs are supported. Changing the maximum does not convert grades from one scale to another.
Does the tool save my grades or export a PDF?
The calculator code does not upload entries or save a results history, and there is no built-in PDF export. Use Copy result to keep the result text before resetting or leaving the page. Your browser may independently restore form entries.
Is the OpenStudyInfo SGPA Calculator official?
No. OpenStudyInfo is an independent educational website, not a university examination authority. Use the calculator for checking and planning; your institution’s grading rules and official grade card remain final.
