Calculate your Class 12 aggregate percentage using your board's specific rules. CBSE, ICSE, and state boards have different methods — best-of-5, all subjects average, or weighted with internal marks.
What is Class 12 %?
Class 12 aggregate is the percentage used for college admission applications. The exact calculation depends on the board: CBSE typically uses best-of-5 (top 5 subjects' average). ICSE uses average of all 6 subjects including English. State boards (Maharashtra, Karnataka, Tamil Nadu, UP) have their own rules — some use all subjects, some use best-of-5, some apply internal marks weighting.
Getting the right calculation matters: a 78% on one method might be 82% on another. Many college applications still use percentage cutoffs (60%, 75%, 85%), so accuracy here is what determines whether you make the cutoff.
How Class 12 aggregate is calculated
CBSE best-of-5: pick the 5 highest-scoring subjects from your 5-6 papers. English is mandatory (your highest language paper). Aggregate = sum of these 5 / 5.
ICSE average: average of all 6 subjects (English + 5 others). Internal practical marks are included in subject totals.
State boards: Most use sum of all main subjects / count. Some (like Maharashtra HSC) treat practical marks separately.
Each board's mark sheet includes the aggregate percentage already calculated. The calculator is useful for projecting future percentage or applying a different board's rule to your marks.
How to use this calculator
Enter all your subject marks (out of 100)
Use the marks from your Class 12 board mark sheet. Total per subject is typically 100 (combined theory + practical/internal).
Pick your board
CBSE, ICSE, Maharashtra State Board, Karnataka, Tamil Nadu, UP — each has its own rule. The calculator applies the right method automatically.
Read your aggregate
Calculator outputs the percentage using your board's official method. Use this on college applications, scholarship forms, and competitive exam eligibility checks.
When to use it
College applications with percentage cutoffs
Many UG programs (especially professional courses) still use percentage cutoffs. CBSE students need their best-of-5; ICSE students use the full average. Calculator ensures you're not under-claiming or over-claiming.
Scholarship eligibility
Many merit scholarships require 80%, 85%, or 90% Class 12 aggregate. Calculator gives the figure to put on the application — using your board's specific method.
JEE/NEET eligibility
JEE Main (general) requires 75% in Class 12 or being in the top 20 percentile of your board. NEET requires 50% in PCB. Calculator helps you check eligibility before applying.
Common mistakes to avoid
Using board mark sheet's aggregate without checking the rule
Some boards show aggregate as sum/total without best-of-N. If the college applies best-of-N, you need to compute it yourself. Use the calculator.
Forgetting English / language is mandatory
For best-of-5/6 rules, language papers are mandatory inclusions. You cannot drop English to boost the aggregate by including a higher non-language subject.
