- 2. CalculatePress Calculate to get your SGPA with the full working and an approximate percentage.
- 3. Switch to all semestersUse the second tab to combine semester results into your overall CGPA.
JNTUH R22 grade points
The calculator uses the grade table from the JNTUH R22 B.Tech academic regulations:
| Grade | Grade points | Marks band |
|---|---|---|
| O | 10 | 90 and above |
| A+ | 9 | 80–89 |
| A | 8 | 70–79 |
| B+ | 7 | 60–69 |
| B | 6 | 50–59 |
| C | 5 | 40–49 |
| F | 0 | below 40 |
| Ab | 0 | absent |
R18 and earlier regulations used similar letters; if you're in an older batch, compare the table in your regulations and edit the points if needed.
Worked example
The sample semester loaded with the tool:
| Subject | Credits | Grade | Credits × points |
|---|---|---|---|
| Mathematical and Statistical Foundations | 4 | B+ (7) | 28 |
| Data Structures | 3 | A (8) | 24 |
| Computer Organization and Architecture | 3 | B (6) | 18 |
| Object Oriented Programming through Java | 3 | A+ (9) | 27 |
| Software Engineering | 3 | A (8) | 24 |
| Java Lab | 1 | O (10) | 10 |
| Data Structures Lab | 1 | A+ (9) | 9 |
| Total | 18 | 140 |
SGPA = 140 ÷ 18 = 7.78.
Using R22's conversion, (7.78 − 0.5) × 10 gives about 72.78%. Across semesters of 7.45 (20 credits), 7.9 (20) and 8.15 (21), CGPA = 478.15 ÷ 61 = 7.84, or 73.39%.
About the R22 percentage rule
The R22 regulations state that percentage of marks is calculated as (CGPA − 0.5) × 10. This is lower than a straight × 10, so don't multiply by 10 on forms that ask for JNTUH percentage. SGPA and CGPA are rounded to two decimal places in the regulations, and the calculator does the same. Failed and absent subjects carry 0 points until you clear them in a supplementary exam.
Frequently asked questions
Is SGPA calculated with failed subjects?
A failed subject carries 0 points, and memos often show no SGPA while a subject of that semester is pending. Check the regulations for your batch. The calculator still shows what the number would be.
Does this work for JNTUK or JNTUA?
Their scales are close but not identical. Edit the grade points to match your regulations.
Is this JNTUH's official calculator?
No. Uncodemy is not connected with JNTUH. Your memo is final.
Is the JNTUH SGPA calculator free?
Yes, completely. You can type in everything and use the JNTUH SGPA calculator with no sign-up. When you ask for the result the first time, we ask for your name and WhatsApp number once; after that the JNTUH SGPA calculator and every other Uncodemy tool open straight away.
