CBSE Grade Calculator
A CBSE grade calculator converts marks into grades on the 9-point A1–E2 scale, shows the grade point for each subject, and works out your overall CGPA — plus the approximate percentage.
Enter each subject's marks, see the grade update instantly, and get your CGPA from the best five subjects.
Your subjects
CGPA is the average grade point of your best five subjects. Percentage ≈ CGPA × 9.5.
Uses CBSE's fixed marks-range scale (the planning proxy). Official board grades use relative 1/8th positional ranking — see the note below.
Looking for something specific?
This tool turns marks into grades and CGPA. To convert a CGPA you already have into a percentage on its own, use the CGPA to Percentage Calculator. For schools that need to generate full CBSE, ICSE and State Board report cards from marks entry — with grades, CGPA and remarks printed automatically — that's handled by SchoolDeck report cards.

CBSE marks to grade chart (Class 9 & 10)
The 9-point scale maps a percentage to a grade and a grade point. These are the fixed marks ranges schools use for planning and internal assessment.
| Grade | Marks range (%) | Grade point | Meaning |
|---|---|---|---|
| A1 | 91 – 100 | 10 | Outstanding |
| A2 | 81 – 90 | 9 | Excellent |
| B1 | 71 – 80 | 8 | Very good |
| B2 | 61 – 70 | 7 | Good |
| C1 | 51 – 60 | 6 | Fair |
| C2 | 41 – 50 | 5 | Average |
| D | 33 – 40 | 4 | Pass |
| E1 | 21 – 32 | — | Essential repeat |
| E2 | 0 – 20 | — | Essential repeat |
The passing mark is 33% per subject. E1 and E2 indicate the subject must be repeated.
How it works
From marks to CGPA in four steps.
-
1
Enter each subject's marks
Type the marks obtained and the maximum marks. The tool converts them to a percentage first, so any max value works.
-
2
Read the grade & grade point
The percentage is mapped to a grade from A1 to E2 and its grade point, shown next to each subject.
-
3
Get the CGPA
The tool averages the grade points of your best five subjects to give the overall CGPA.
-
4
See the approximate percentage
It multiplies the CGPA by 9.5 — CBSE's official formula — to show the approximate overall percentage.
The CBSE grading system, explained
CBSE moved away from printing exact marks on the Class 10 marksheet to reduce the pressure of chasing single decimals. Instead, each subject gets a grade on a 9-point scale from A1 down to E2, and the grade points feed into a single number — the CGPA — that summarises overall performance.
What CGPA means and how it's worked out
CGPA stands for Cumulative Grade Point Average. It is the average of the grade points of the best five main subjects. If a student scores grade points of 10, 9, 8, 9 and 9, the total is 45, and dividing by five gives a CGPA of 9.0. The sixth (additional) subject is generally used only to replace a weaker main subject under the best-of-five rule, which can lift the aggregate.
Converting CGPA to a percentage
CBSE provides a simple conversion: multiply the CGPA by 9.5 to get the approximate overall percentage. A CGPA of 9.2 is roughly 87.4%, and a CGPA of 8.0 is roughly 76%. This is an approximation that many Class 11 admission desks and scholarship forms accept, but it is not the exact aggregate of marks. If you only need to convert a CGPA figure to a percentage, the dedicated CGPA to Percentage Calculator does just that.
Fixed marks ranges vs the 1/8th positional rule
This is the most misunderstood part of CBSE grading. On the official board marksheet, grades are awarded by relative position: CBSE sorts everyone who passed a subject in descending order of marks and gives the top one-eighth the A1 grade, the next eighth A2, and so on. Because of this, the exact mark needed for an A1 shifts slightly each year depending on how hard the paper was — in a tough year, even high-80s marks can earn an A1.
The fixed marks ranges in the chart above — 91–100 for A1, 81–90 for A2 and so on — are the planning proxy that schools use for internal assessment and for estimating grades before results day. This calculator uses the fixed ranges because that is what is useful for planning; just remember the final board grade is set by the positional rule.
Internal assessment and the 80 + 20 split
For most Class 10 subjects, the final 100 marks come from an 80-mark theory paper plus 20 marks of internal assessment — periodic tests, notebook submission and subject enrichment activities. Both components count towards the grade, and a student needs at least 33% to pass. Enter the combined marks out of 100 in this tool to get the grade for that subject.
Does it work for Class 12?
Yes. Class 12 uses the same 9-point A1 to E2 scale, so the marks-to-grade conversion is identical. The differences are the subject combination and that science subjects with practicals split marks as 70 theory plus 30 practical. Enter the total out of the maximum for each subject and the grades and CGPA are calculated the same way.
From a calculator to a full report card
Working out one student's grades here is quick. A school computing grades and CGPA for hundreds of students every term, and printing CBSE, ICSE or State Board report cards from that, needs it done automatically from marks entry. Schools use SchoolDeck's report card module to generate grades, CGPA, NEP 2020 holistic progress cards and remarks in one click from the marks register.

Frequently asked questions
CBSE grade calculator — FAQs
What is the CBSE grading system?
+
The CBSE grading system for Classes 9 and 10 is a 9-point scale that converts marks into grades from A1 (highest) to E2 (lowest). A1 is 91–100, A2 is 81–90, B1 is 71–80, B2 is 61–70, C1 is 51–60, C2 is 41–50, and D is 33–40, with E1 (21–32) and E2 (0–20) treated as Essential Repeat. Each grade carries a grade point from 10 down to 4.
How do I calculate my CBSE grade from marks?
+
Convert your marks to a percentage — marks obtained divided by maximum marks, times 100 — then map the percentage to the CBSE band. For example, 76 out of 100 is 76%, which falls in 71–80, so the grade is B1 with a grade point of 8. This calculator does the conversion automatically for any maximum-marks value.
How is CBSE CGPA calculated?
+
CGPA is the average of the grade points of your best five main subjects. Add the five grade points and divide by five. For example, grade points of 10, 9, 8, 9 and 9 add up to 45, and 45 divided by 5 gives a CGPA of 9.0. This tool computes it for you as you enter marks.
How do I convert CBSE CGPA to percentage?
+
Multiply your CGPA by 9.5 — this is CBSE's official approximation formula. For example, a CGPA of 9.0 is about 85.5%, and a CGPA of 8.0 is about 76%. It is an approximation, not the exact aggregate. To convert a CGPA to percentage on its own, use the dedicated CGPA to Percentage Calculator.
Are CBSE board grades based on fixed marks or relative ranking?
+
On the official CBSE board marksheet, grades are awarded by relative position — the top one-eighth of students who pass a subject get A1, and the cut-offs shift each year with the difficulty of the paper. The fixed marks ranges (91–100 = A1, and so on) are the planning proxy that schools use for internal assessment. This calculator uses the fixed marks ranges, which is the version useful for estimating your grade.
What are the CBSE grade points for each grade?
+
A1 carries 10 points, A2 carries 9, B1 carries 8, B2 carries 7, C1 carries 6, C2 carries 5, and D carries 4. E1 and E2 are failing grades that require the subject to be repeated and do not carry a passing grade point. These points are what go into the CGPA calculation.
Is this CBSE grade calculator free?
+
Yes. The calculator is completely free, needs no sign-up, and runs entirely in your browser, so the marks you enter are never uploaded or stored. You can use it as often as you like on any phone or computer.
Does this tool work for Class 12 as well?
+
The 9-point A1 to E2 scale is the same for Class 12, so the marks-to-grade conversion works the same way. The main difference is the subject combination and that some Class 12 science subjects split marks as 70 theory plus 30 practical. Enter the total marks and maximum for each subject and the grades and CGPA are calculated identically.
