This converter is built on the official CBSE 9-point grading system used across CBSE-affiliated schools in India. Percentage, grade, grade point, CGPA estimate, and pass/fail status are all calculated according to CBSE's own rules for Class 10 and Class 12.
Treat it as a quick reference, not a substitute for your marksheet. Always confirm your final grade against your official CBSE result or your school's records, and check the official CBSE website for anything that might have changed.
CBSE moved to a 9-point grading scale to judge student performance in a way that's a bit less rigid than raw marks alone. Instead of ranking students purely by score, it groups performance into defined percentage bands, each with its own grade and grade point.
The CBSE grading system for 2026 still follows this same structure across Class 10, Class 12, and internal school assessments. Knowing how marks map to grades makes it easier to set realistic targets and to explain your performance to colleges, employers, or scholarship committees.
Three things sit at the core of the system:
A1 (91–100%) — Outstanding. Grade point 10. This is what competitive colleges and merit scholarships look for.
A2 (81–90%) — Excellent. Grade point 9. Meets the cutoff for most top-tier college programs.
B1 (71–80%) — Very good. Grade point 8. Clears eligibility for most undergraduate admissions.
B2 (61–70%) — Good. Grade point 7. Fine for general admissions, though professional courses may want more.
C1 (51–60%) — Adequate. Grade point 6. A comfortable pass, but it can narrow your options for competitive programs.
C2 (41–50%) — Below average. Grade point 5. Passes CBSE's requirement, but this is usually the range where students realise they need to change something.
D (33–40%) — Minimum pass. Grade point 4. Meets the 33% rule, though it won't help much on a college application.
E (Below 33%) — Fail. Grade point 0. Doesn't meet CBSE's minimum passing bar.
| Percentage Range | Grade | Grade Point | Status |
|---|---|---|---|
| 91–100% | A1 | 10 | Pass |
| 81–90% | A2 | 9 | Pass |
| 71–80% | B1 | 8 | Pass |
| 61–70% | B2 | 7 | Pass |
| 51–60% | C1 | 6 | Pass |
| 41–50% | C2 | 5 | Pass |
| 33–40% | D | 4 | Pass |
| Below 33% | E | 0 | Fail |
CGPA is the number that matters most on your CBSE result card. It condenses your performance across every subject into one figure, and it's what colleges, scholarship boards, and even some employers actually look at.
To get there, convert each subject's marks to a grade point using the scale above, then run the formula below.
Formula: CGPA = (sum of grade points across main subjects) ÷ (number of main subjects). Optional or additional subjects are usually left out of this.
Example: Say you scored A1 (10), A2 (9), B1 (8), B2 (7), and C1 (6) across five subjects. That's (10 + 9 + 8 + 7 + 6) ÷ 5 = 8.0 CGPA.
Converting CGPA back to percentage: multiply by 9.5. A CGPA of 8.0 works out to roughly 76%. This is a rough estimate CBSE itself uses for reference, not an exact substitute for your actual percentage, so don't be surprised if it's off by a point or two from your real marksheet.
| Metric | Value |
|---|---|
| Passing marks | 33% |
| Max grade point | 10 |
| Point scale | 9 |
Before CBSE can assign a grade, your marks need to become a percentage. The formula stays the same no matter what the paper is out of.
Formula: Percentage = (marks obtained ÷ maximum marks) × 100
A few worked examples:
Notice that 68/80 and 76/100 land in different grades even though the raw numbers look close. That's the part people usually miss when they're eyeballing it instead of doing the actual conversion, and it's exactly why the calculator on this page always converts to a percentage first before it maps anything to a grade.
90 marks (out of 100): 90% → Grade A2 → grade point 9. That's just one percentage point shy of A1, which starts at 91%.
85 marks: 85% → Grade A2 → grade point 9. Sits comfortably inside the 81–90% A2 band.
75 marks: 75% → Grade B1 → grade point 8. Falls within the 71–80% range.
60 marks: 60% → Grade C1 → grade point 6. Right at the top edge of the C1 band.
33 marks: 33% → Grade D → grade point 4. This is the exact minimum needed to pass.
Passing percentage. CBSE requires at least 33% in each subject. That's Grade D, grade point 4. Fail even one subject and your overall result can be marked Compartment or Fail depending on your case.
Grade points and CGPA. Your subject grade points get averaged into your CGPA, the figure printed on your CBSE result card and used widely for admissions.
Scale stability. CBSE's 9-point system has stayed consistent for years, but the board can revise its guidelines. Check the official CBSE site before exam season just in case something's changed.
Verification. Treat this as a planning tool, not a legal record. Always confirm your final result against your school or your official CBSE marksheet.
Want to do it by hand? Here's the exact logic the calculator runs automatically:
Or just use the calculator above and skip the manual math entirely.
Class 10 (Secondary): Assessed across five main subjects. CGPA is the average grade point across those five. A sixth, additional subject can be swapped in if it raises your CGPA.
Class 12 (Senior Secondary): Same 9-point scale. Unlike Class 10, your Class 12 marksheet shows the actual percentage alongside the grade and grade point.
Internal assessment. For most subjects, CBSE folds in school-based internal assessment marks along with your theory exam score before calculating the final grade.
Compartment exam. If you land Grade E in a subject, you're eligible to sit the compartment exam. Clearing it is what officially passes you in that subject.
Track subject by subject. Run your marks through this calculator after every test. Catching a slide early gives you time to actually fix it.
Spot your weak subjects. If one subject keeps landing you in C1 or C2 while everything else sits at B1 or higher, that's the one dragging your CGPA down. A bit of focused effort there tends to move the needle more than spreading yourself thin.
Set a real target. "Do better" isn't a plan. "Move Science from B2 to B1" is, because now you know the exact percentage you need to hit.
Recalculate regularly. Checking your grade after each test shows you how much the next exam can actually shift your overall standing.
Converting marks to a grade by hand is fine for one subject. It gets tedious, and mistake-prone, once you're tracking several subjects across several tests.
No math errors. The calculator runs the percentage formula and grade mapping for you, so there's no risk of a rounding slip or misreading the chart.
Any maximum marks. Out of 100, 80, 50, doesn't matter, it adjusts automatically.
CGPA estimate on the spot. Grade points show up immediately, so you can total them across subjects and get a running estimate for mid-year planning.
Works anywhere. Phone, tablet, or desktop, no installation, no account.

This converter is built on the standard CBSE 9-point grading scale and is meant for self-assessment, not official record-keeping. CBSE can revise its grading pattern, passing criteria, or evaluation rules at any point. Treat this page as a planning aid, and confirm your actual result with your school, your official CBSE marksheet, or the CBSE official website.
Calculate your percentage first: (marks obtained ÷ maximum marks) × 100. Then match it to the official chart. 85%, for example, falls in the 81–90% band, which is Grade A2, grade point 9. This calculator does that automatically as you type.
B1 means you scored between 71% and 80%. It's a solid, above-average result that shows a good grasp of the subject, with some room left to reach A2 or A1.
A2 covers 81% to 90%. It's just below the top grade, A1, and puts you among the stronger performers in your class.
It's a 9-point system: A1 (91–100, grade point 10), A2 (81–90, grade point 9), B1 (71–80, grade point 8), B2 (61–70, grade point 7), C1 (51–60, grade point 6), C2 (41–50, grade point 5), D (33–40, grade point 4), and E, below 33, which needs improvement.
85 out of 100 is 85%, landing in the 81–90% band, Grade A2, grade point 9. If your paper isn't out of 100, the calculator converts to a percentage first before assigning the grade.
90 out of 100 is 90%, still Grade A2, grade point 9. You'd need 91% to cross into A1, so 90 is right at the edge.
Average the grade points across your main subjects: CGPA = (sum of grade points) ÷ (number of subjects). Grade points of 10, 9, 8, 7, and 6 across five subjects give you (10+9+8+7+6) ÷ 5 = 8.0. Multiply by 9.5 to estimate the percentage: 8.0 × 9.5 = 76%.
Yes. It works for any maximum marks value. It converts to a percentage first, then assigns the grade, so the result is accurate no matter what the paper was out of.
