Formula & Calculation Methodology
Standard Hourly Rate = Monthly Basic Gross / (Working Days × Daily Hours). Overtime Pay = Overtime Hours × (Hourly Rate × Multiplier).
Hourly\_Rate = \frac{Gross\_Salary}{Days \times Hours}, \quad OT\_Pay = OT\_Hours \times (2.0 \times Hourly\_Rate)
Step-by-Step Worked Example
Monthly Gross: ₹45,000 | 26 Working Days | 8 Hours/Day | 18 Overtime Hours | 2x Multiplier
- 1. Total Regular Working Hours = 26 × 8 = 208 hours/month
- 2. Standard Hourly Rate = ₹45,000 / 208 = ₹216.35/hour
- 3. 2x Overtime Hourly Rate = ₹216.35 × 2.0 = ₹432.69/hour
- 4. Overtime Earnings = 18 × ₹432.69 = ₹7,788.46
- 5. Total Monthly Salary with Overtime = ₹45,000 + ₹7,788 = ₹52,788
Result: Standard Rate: ₹216/hr | 2x OT Rate: ₹433/hr | OT Bonus: +₹7,788 | Total Pay: ₹52,788
