Free Overtime Calculator Online
Overtime pay with regular/OT/double-time rates and total weekly earnings
The Overtime Calculator computes an employee's total weekly pay when some hours fall under regular time, overtime (1.5×), and double time (2×) rates. It's used by hourly workers checking their expected pay, managers planning shift costs, and HR teams ensuring compliance with labour law overtime thresholds.
Frequently Asked Questions
About the Overtime Calculator
Overtime pay rules are mandated by labour law in most countries, but the exact thresholds and multipliers vary by jurisdiction. In the US, federal law (FLSA) requires 1.5× pay for hours over 40 per week, though some states add daily overtime thresholds or double-time requirements above 12 hours in a day.
This calculator handles all three pay tiers — regular time, time-and-a-half, and double time — with configurable thresholds. Enter your base hourly rate and hours worked in each tier to get a full earnings breakdown. It also shows your effective average hourly rate for the week, which can be useful for tax withholding estimates.
Employers can use it to model the cost of extending a shift versus hiring additional staff; employees can verify that their payslip overtime figure is correct.
Formula Used
OT Pay = (Hourly Rate × 1.5) × Overtime Hours

Example Calculation
Pay for a warehouse worker who clocked 52 hours this week
📥 Inputs
- Base hourly rate: $20.00
- Regular hours (up to 40): 40
- Overtime hours (40–48, at 1.5×): 8
- Double-time hours (above 48, at 2×): 4
🔢 Calculation Steps
- 1Regular pay: 40 × $20.00 = $800.00
- 2Overtime pay (1.5×): 8 × $20.00 × 1.5 = $240.00
- 3Double-time pay (2×): 4 × $20.00 × 2.0 = $160.00
- 4Total gross pay: $800 + $240 + $160 = $1,200.00
- 5Effective hourly rate this week: $1,200 ÷ 52 hours = $23.08/hr average
