Overtime Calculator: Complete Indian Labour Law OT Guide
When factory workers, technicians, or commercial employees stay back beyond their standard shift hours to meet production deadlines, Indian labour law mandates that employers compensate them with Overtime (OT) Pay.
Governed by Section 59 of the Factories Act, 1948 and state-level Shops and Commercial Establishments Acts, overtime is calculated at twice the ordinary rate of wages (2.0x Double Pay) whenever work exceeds 9 hours in a day or 48 hours in a week. Our free online Overtime Calculator evaluates regular hourly wage rates, applies statutory 2.0x or 1.5x rate multipliers, and computes your exact Monthly Overtime Payout and Gross Earnings.
