Dear Suhas,
Bonus calculation is on the salary (with general components as basic+DA) up to Rs. 3,500. That is, if the salary is below or equal to Rs. 3,500, the actual salary will be taken for bonus calculation. If it is above Rs. 3,500 and up to a maximum of Rs. 10,000; Rs. 3,500 will be the salary for bonus calculation. For a salary above Rs. 10,000, there will not be any statutory claim for a bonus.
