Bonus Calculation Formula

The bonus calculation formula governs the annual statutory bonus that Indian employers must pay to eligible employees under the Payment of Bonus Act, 1965. The calculation rests on two ceilings — an eligibility ceiling of ₹21,000 per month and a calculation ceiling of ₹7,000 per month — both set by the Payment of Bonus (Amendment) Act, 2015 (Act 6 of 2016). Within these caps, statutory bonus must be at least 8.33% of qualifying wages and may go up to 20% based on the employer’s allocable surplus. The annual statutory bonus is one of the most consistent items in Indian payroll, payable to every covered employee within 8 months of the close of the accounting year.

What is the Bonus Calculation Formula?

The Payment of Bonus Act, 1965 applies to every factory and to every other establishment employing 20 or more persons on any day during the accounting year. The Act creates a statutory profit-sharing obligation independent of any contractual or discretionary bonus the employer may otherwise pay. The formula operates in three stages: determine eligibility, compute qualifying wages, and apply the bonus percentage.

The structural formula:

Annual Statutory Bonus = Qualifying Wages x Bonus Percentage

Where:

• Qualifying Wages = lower of (actual basic + DA) and ₹7,000 per month, multiplied by 12 (or by the number of months in service if less than a full year, pro-rated).
• Bonus Percentage = 8.33% (statutory minimum) to 20% (statutory maximum), determined by the employer’s allocable surplus computed under the Act.

For state-scheduled employments where the notified minimum wage exceeds ₹7,000 per month, the calculation ceiling is the minimum wage instead — a clarification introduced by the 2015 amendment to prevent under-payment in higher-wage states.

Calculation Formula with Worked Example

Example 1: Eligible Employee at Minimum Bonus

An employee with basic + DA of ₹15,000 per month, working the full accounting year of 12 months, in an establishment paying minimum statutory bonus:

Example 2: Eligible Employee at Maximum Bonus

The same employee, but the employer has sufficient allocable surplus to pay the maximum:

Example 3: Mid-Year Joiner

A new hire with basic + DA of ₹18,000 per month (eligible since ≤ ₹21,000), joining 1 October and working 6 months in the accounting year ending 31 March:

An employee with basic + DA above ₹21,000 is ineligible for statutory bonus, although the employer may pay a discretionary bonus outside the Act.

Tax Treatment

Statutory bonus is fully taxable as salary income under Section 17(1)(iv) of the Income Tax Act 1961 in the hands of the recipient employee. There is no separate exemption — bonus is treated identically to monthly salary for tax purposes. TDS is applied by the employer at the time of payment, and the bonus appears on the employee’s Form 16.

For the employer, statutory bonus is a deductible business expense under Section 37(1) of the Income Tax Act in the year of payment. Bonus is deductible on a payment basis (not accrual basis) under Section 43B — the employer must actually pay the bonus by the due date for filing the income tax return to claim the deduction.

Statutory Ceilings: 2015 Amendment

The current ceilings were set by the Payment of Bonus (Amendment) Act, 2015 (Act 6 of 2016), which amended Sections 2(13) and 12 of the Payment of Bonus Act, 1965.

The amendment was originally made effective retrospectively from 1 April 2014, but the retrospective effect was stayed by various High Courts (Karnataka, Kerala, Madras, Punjab & Haryana, Allahabad). Operationally, most employers apply the revised ceilings prospectively from FY 2015-16 onwards, in line with the labour department’s effective enforcement window.

Allocable Surplus, Set On, Set Off

The percentage between 8.33% and 20% is determined by the employer’s allocable surplus, calculated under the Second Schedule to the Act: gross profit minus depreciation, prior charges, and a percentage return on capital, with 67% of the available surplus (60% for foreign companies) treated as allocable. Where allocable surplus exceeds the 20% payout, the excess is set on — carried forward up to 4 years. Where allocable surplus falls below the 8.33% minimum, the shortfall is set off for offset against future surpluses, also up to 4 years.

Common Employer Mistakes

1. Computing on actual salary instead of capped wages. Statutory bonus uses the ₹7,000 cap, not actual basic+DA. Over-payment is not refundable.
2. Excluding eligible employees above ₹7,000 wages. The eligibility ceiling is ₹21,000. Employees earning between ₹7,001 and ₹21,000 are eligible; bonus is just calculated on the ₹7,000 cap.
3. Including apprentices. Apprentices under the Apprentices Act, 1961 are explicitly excluded under Section 32(viii).
4. Missing the 30-November deadline. The 8-month payment window for an April-to-March accounting year closes on 30 November. Late payment triggers labour-department scrutiny.
5. Forgetting Set On / Set Off carryforward. Prior-year set-off obligations may require more than the 8.33% minimum even in a recovery year. Form C tracking is mandatory.

How Omnivoo Handles Bonus Calculation

Omnivoo identifies bonus-eligible employees automatically each accounting year, applying the ₹21,000 eligibility ceiling and the ₹7,000 (or scheduled minimum wage) calculation ceiling for each employee’s location. The platform defaults to the statutory minimum 8.33% unless the client specifies a higher percentage based on allocable surplus, and pro-rates correctly for joiners, leavers, and partial-year employees. Bonus is disbursed within the 8-month statutory window — typically aligned with Diwali — and included in the full and final settlement on a pro-rata basis when an employee exits mid-year. Bonus registers (Form A, B, C) are maintained automatically, available for labour-department inspection without separate effort from the employer.
