How to calculate bonus? 

Now that you are familiar with the types of bonuses, here is a quick snapshot of the calculation of bonus. Before evaluating the formula for the calculation of bonus, you need to first check if you are eligible or not. 

As per the Bonus Act, all employees who have completed at least 30 working days are applicable for a statutory bonus, provided they meet the required criteria. While the minimum bonus is 8.33%, the maximum goes up to 20%. You can avail this bonus only if your monthly salary does not exceed ₹21,000. 

The formula for the calculation of bonus is simple: 

Applicable Bonus = Your Salary x 8.33/100 

The aforementioned formula applies only if your monthly salary is equal to or less than ₹7,000. In case your monthly salary is above ₹7,000, the calculation of bonus happens in this manner: 

Applicable Bonus = 7,000 x 8.33/100 

Using both these formulas after checking your eligibility can help you easily calculate the bonus. 

Calculation of bonus using a hypothetical example 

Here is a simple illustration to help you understand the calculation of bonus. Assume you earn a monthly salary of ₹15,000, which includes the basic salary and the Dearness Allowance. In such an instance, the calculation of bonus happens in the following way: 

Bonus Amount Eligible = 15,000 x 8.33/100 

This is equal to ₹1,250 approximately for a month and ₹14,994 for a year. 

What are the various bonuses available for employees? 

There are different types of bonuses for employees distributed quarterly or annually. While some organisations may offer a one-time payment, others may make recurring payments. Remember that the bonus you earn depends on umpteen factors, such as your position in your company, your performance level, the nature of your job and much more.  

Here are a few kinds of bonuses you need to know before understanding how to calculate bonus. 

  • Spot Bonus 

This kind of bonus is awarded to employees for their exceptional performance and for completing tasks over and above what was expected from them. While this can be a one-time payment, the amount depends on the level of task completed. 

  • Referral Bonus 

This is an additional amount paid by the employer if an employee provides a reference for new talent. However, to avail of this bonus, the new referral needs to complete the probation period of at least 90 days. This may differ from one employer to another.  

  • Annual Bonus 

These bonuses depend on the performance of a company as a whole. Here, the total amount of bonus is directly proportional to profits earned by an organisation during a financial year.  

  • Holiday Bonus 

These are specific bonuses awarded to employees on select holidays and festivals. While they can take the form of gifts and vouchers, some employers also provide monetary benefits.  

  • Longevity Bonus 

These bonuses are paid to employees for their significant contribution to the company across a considerable timeline. Employees may receive them either as a cash reward or in the form of an increment. This bonus encourages an employee to continue working in the same organisation, thereby fostering their loyalty. 

While a bonus payment is a fair act to recognise the efforts of an employee, this also helps employees earn additional funds to manage their finances.
