Statutory 15/26 Gratuity Formula
Gratuity = (15 × Last Drawn Salary × Completed Years) ÷ 26
Variable Definitions:
Last Drawn Salary:Basic Pay + Dearness Allowance (DA) only. Excludes HRA, bonuses & special allowances.
15:Statutory 15 days of wages for each completed year of service.
26:Statutory working days in a month (30 days minus 4 Sundays).
Completed Years:Tenure of service. Periods exceeding 6 months round UP to the nearest full year.

Step-by-Step Worked Examples

Example 1: Salaried Executive with 8 Years 7 Months Service

Problem: Basic Pay is ₹65,000 and DA is ₹5,000. Tenure is 8 years and 7 months.

Step-by-Step Solution:
  1. Calculate Last Drawn Salary = Basic (₹65,000) + DA (₹5,000) = ₹70,000.
  2. Round service tenure: Since 7 months > 6 months, tenure rounds up to 9 completed years.
  3. Apply statutory formula: (15 × 70,000 × 9) ÷ 26 = 9,450,000 ÷ 26 = ₹3,63,461.54.
The executive receives ₹3,63,462 in statutory gratuity.

Example 2: Long-Tenure Professional Exceeding Tax Ceiling

Problem: Basic + DA is ₹1,80,000 with 25 years of continuous service.

Step-by-Step Solution:
  1. Formula calculation: (15 × 1,80,000 × 25) ÷ 26 = ₹25,96,153.85.
  2. Statutory maximum tax exemption limit under Section 10(10) is ₹20,00,000.
  3. Taxable gratuity: ₹25,96,154 - ₹20,00,000 = ₹5,96,154 is added to taxable salary income.
Total Gratuity: ₹25,96,154 | Tax-Free: ₹20,00,000 | Taxable: ₹5,96,154.

Common Mistakes to Avoid

✕ Misconception: Including HRA, Special Allowance, or Annual Performance Bonuses in Last Drawn Salary.

✓ Correct Rule: Under Section 2(s) of the Payment of Gratuity Act, salary strictly includes Basic Pay + Dearness Allowance (DA). Special allowances and incentives are excluded unless specifically contractually provided.

✕ Misconception: Dividing by 30 days instead of 26 days.

✓ Correct Rule: The Supreme Court of India upheld in the Digvijay Woollen Mills case that a month consists of 26 working days for gratuity computations. Dividing by 30 violates statutory requirements.

✕ Misconception: Believing you must complete a full 5 years to the exact day.

✓ Correct Rule: Under Section 2A continuous service rules, completing 4 years and 240 days (for a 6-day work week) or 190 days (for a 5-day work week) satisfies the legal 5-year eligibility condition in court jurisprudence.
