Enter your monthly salary, standard monthly hours, OT hours and the multiplier (1.5x or 2x) to instantly see your hourly rate, overtime pay and total earnings.

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.

Standard overtime multipliers

RegionThresholdMultiplier
India (Factories Act)> 9 hrs/day or 48 hrs/week2× (twice the ordinary rate)
USA (FLSA)> 40 hrs/week1.5× (time-and-a-half)
UKBy contract (no statutory rate)1.0× – 2×
UAE> 8 hrs/day1.25× / 1.5× / 2× (Friday)
EU (avg)> 40 hrs/week1.25× – 1.5×

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 / public-holiday work separately — it usually qualifies for 2×.
  • Save hourly rate snapshots so you can negotiate during appraisal.
