About this calculator
Total weekly pay combines three pay tiers based on hours worked and applicable multipliers. The formula is: Total Pay = (regularHours × hourlyRate) + (overtimeHours × hourlyRate × overtimeMultiplier) + (doubleTimeHours × hourlyRate × 2). Under the federal Fair Labor Standards Act (FLSA), overtime kicks in after 40 hours in a workweek at a minimum multiplier of 1.5 (time-and-a-half). Some states, like California, additionally require double time (2×) for hours worked beyond 12 in a single day. The overtimeMultiplier field lets you enter 1.5 for standard overtime or any rate your employer or union agreement specifies. Double-time hours are always multiplied by 2 regardless of state. This calculator helps workers confirm their paycheck and helps employers model labor costs.
How to use
Assume an hourly rate of $20/hr, 40 regular hours, 6 overtime hours at 1.5×, and 2 double-time hours. Step 1: Regular pay = 40 × $20 = $800. Step 2: Overtime pay = 6 × $20 × 1.5 = $180. Step 3: Double-time pay = 2 × $20 × 2 = $80. Step 4: Total Pay = $800 + $180 + $80 = $1,060. This employee earns $1,060 for the week before taxes and deductions.
Frequently asked questions
When does overtime pay legally kick in for hourly workers?
Under the federal FLSA, overtime is required for non-exempt hourly employees who work more than 40 hours in a single workweek, and must be paid at no less than 1.5 times the regular rate. Some states have stricter rules — California requires daily overtime for hours beyond 8 in a workday and double time beyond 12 hours. Salaried employees classified as exempt (typically earning over $684/week in a qualifying role) are generally not entitled to overtime. Always check your state's Department of Labor rules for specifics.
What is the difference between overtime and double-time pay?
Overtime is typically paid at 1.5 times (150%) the regular hourly rate for hours that exceed the standard threshold, usually 40 per week. Double time is paid at exactly 2 times (200%) the regular rate and applies under specific conditions — such as working more than 12 hours in a day in California or working on designated holidays per a union agreement. Not all employers are required to pay double time; it depends on state law and employment contracts. This calculator lets you enter both tiers separately for an accurate total.
How do I calculate overtime pay if my rate changes mid-week?
When an employee works at two different rates in the same workweek, the FLSA requires calculating a weighted average rate before applying the overtime premium. You divide total straight-time earnings by total hours worked to get the blended rate, then multiply overtime hours by 0.5 times that blended rate to find the premium owed. This calculator assumes a single consistent rate throughout the week. For blended-rate scenarios, consult your payroll software or HR department for the precise weighted-average calculation.
