Overtime Pay Calculator
Calculate your total weekly paycheck when you've worked regular, overtime, and double-time hours. Ideal for hourly workers, payroll staff, and managers verifying compliance with wage rules.
About this calculator
In the United States, the Fair Labor Standards Act (FLSA) requires that non-exempt employees earn at least 1.5× their regular rate for hours beyond 40 per week — commonly called 'time-and-a-half.' Some industries and union contracts also define double time (2×) for hours beyond a daily or weekly threshold. Total pay is calculated as: Total Pay = (regularHours × hourlyRate) + (overtimeHours × hourlyRate × overtimeMultiplier) + (doubleTimeHours × hourlyRate × 2). The overtime multiplier is typically 1.5, but you can enter any value your contract specifies. Regular pay covers the standard workweek hours, overtime covers the excess hours at the premium rate, and double time applies to the highest-tier hours. Always verify your state or industry rules, as California, for instance, applies daily overtime thresholds rather than only weekly ones.
How to use
A warehouse worker earns $18/hour. This week they worked 40 regular hours, 6 overtime hours at 1.5×, and 2 double-time hours. Regular pay: 40 × $18 = $720. Overtime pay: 6 × $18 × 1.5 = 6 × $27 = $162. Double-time pay: 2 × $18 × 2 = 2 × $36 = $72. Total pay = $720 + $162 + $72 = $954. Without the overtime and double-time premiums, the same 48 hours at base rate would have paid only $864 — a $90 difference that the calculator makes immediately visible.
Frequently asked questions
How is overtime pay calculated for salaried non-exempt employees?
For salaried non-exempt workers, you first derive a regular hourly rate by dividing the weekly salary by the number of hours the salary is intended to cover (typically 40). That rate is then used in the same formula as for hourly workers: overtime hours are paid at 1.5× that derived rate. For example, a $800/week salary implies a $20/hour regular rate, so each overtime hour earns an additional $10 on top of the base rate already included in the salary. This is often called the 'half-time' or 'fluctuating workweek' method in FLSA terminology.
What is the difference between overtime pay and double time pay?
Overtime pay is a premium paid for hours worked beyond a set threshold — in most U.S. states, hours beyond 40 per week at 1.5× the regular rate. Double time is a higher premium, paying 2× the regular rate, typically triggered by very long shifts (over 12 hours in California), seventh consecutive workdays, or union agreements. Not all workers are entitled to double time by federal law; it depends on state regulations and employment contracts. This calculator lets you enter both categories separately so your total reflects whichever rules apply to your situation.
Why does my overtime multiplier matter when calculating total pay?
The multiplier directly scales every overtime hour, so even a small difference compounds quickly over multiple hours. At $20/hour, the difference between a 1.5× and a 1.0× multiplier is $10 per overtime hour — over 10 overtime hours per week that is $100 per week or $5,200 per year. Some industries negotiate multipliers above 1.5× in collective bargaining agreements, while others use 1.25× for certain premium shifts. Entering your exact contractual multiplier ensures the calculated pay is accurate and can be used to verify your paycheck or model scheduling scenarios.
