How the overtime calculator works
The calculator first derives your hourly rate from your monthly salary and standard hours. It then multiplies the OT hours by your chosen multiplier (1.5× or 2×) to give the overtime amount, and adds it back to your base for total earnings.
Select the applicable overtime rule
Eligibility, thresholds, ordinary-pay definitions and multipliers vary by jurisdiction, worker classification and contract. This calculator applies your inputs; it does not determine legal entitlement. Confirm the correct rate with payroll or a qualified adviser.
Worked example
Monthly salary ₹40,000 • Standard hours 200 • OT hours 20 • Multiplier 1.5×
Hourly rate = 40,000 / 200 = ₹200 → OT pay = 200 × 20 × 1.5 = ₹6,000 → Total = ₹46,000.
Tips to maximize OT pay
- Log every OT hour in writing (email/Slack to manager), verbal OT is rarely paid.
- Track weekend and public-holiday work separately; any premium depends on the applicable rules.
- Save hourly rate snapshots so you can negotiate during appraisal.
Overtime multipliers at a 200 per hour base rate
| Multiplier | Per overtime hour | 10 overtime hours |
|---|---|---|
| 1.25x | 250 | 2,500 |
| 1.5x (time and a half) | 300 | 3,000 |
| 2x (double time) | 400 | 4,000 |
