Free overtime calculator. Calculate overtime pay at 1.5× or 2× rates, weekly and annual OT earnings, effective hourly rate, and OT scenarios.
The Overtime Calculator computes your overtime pay at time-and-a-half (1.5×) or double-time (2×) rates. Enter your hourly rate, regular hours, and overtime hours to see total weekly pay, annual overtime earnings, the OT premium over straight time, and your effective blended hourly rate.
Under the Fair Labor Standards Act (FLSA), non-exempt employees must be paid at least 1.5× their regular rate for hours worked beyond 40 in a workweek. Some states like California require overtime after 8 hours in a single day and double-time after 12 hours or on the 7th consecutive day worked.
The overtime scenarios table shows how different OT hour levels change your weekly and annual pay, while the rate impact table reveals how your base rate amplifies through overtime. Use presets for common scenarios including California's double-time rules. Check the example with realistic values before reporting. Use the steps shown to verify rounding and units. Cross-check this output using a known reference case.
Overtime can significantly boost earnings but the math is often confusing. This calculator shows exactly how much extra you earn, the true premium from the OT multiplier, and helps you decide whether overtime opportunities are worth the extra hours based on your effective rate. Keep these notes focused on your operational context.
OT Rate = Hourly Rate × OT Multiplier Weekly Pay = (Regular Hours × Rate) + (OT Hours × OT Rate) + (DT Hours × 2 × Rate) Effective Rate = Total Weekly Pay ÷ Total Hours Annual OT Premium = (OT Rate − Base Rate) × OT Hours × Weeks
Result: Weekly pay: $1,375, OT premium: $6,250/year
Regular: $1,000 (40×$25). OT: $375 (10×$37.50). Total: $1,375/week. Annual: $68,750. OT premium over straight time: $125/week × 50 weeks = $6,250.
The FLSA requires overtime after 40 hours per workweek. However, states like California, Alaska, Colorado, and Nevada have daily overtime trigger (typically after 8 hours). California's rules are the most complex: 1.5× after 8 hours/day, 2× after 12 hours/day, and 2× for all hours on the 7th consecutive workday.
The "overtime premium" is the extra payment above what straight time would pay. If you earn $25/hr and work 10 OT hours at $37.50, you earn $375. At straight time, those same hours would pay $250. The premium is $125 — pure extra compensation for the inconvenience of extended work.
After taxes, the real OT premium shrinks. That $37.50/hr OT rate might net $25-$28/hr after 30-40% taxes. Factor in fatigue, reduced productivity, and personal time cost, and some workers find diminishing returns beyond 50-55 hours/week. The effective rate helps quantify this.
Under FLSA, non-exempt employees earn overtime at 1.5× for hours over 40 in a workweek. Some states have daily overtime (after 8 hours/day). Salaried exempt employees generally do not qualify.
Standard overtime is time-and-a-half (1.5× your regular rate). So a $20/hr worker earns $30/hr in overtime. Some situations require double time (2× rate).
Overtime is not taxed at a special rate. However, higher total earnings may push some income into a higher marginal bracket. The bigger paychecks may have more withheld, but this adjusts at tax filing time.
Double time pays 2× the regular rate. California requires it after 12 hours in a day and for all hours on the 7th consecutive workday. Federal law does not mandate double time.
It depends on exempt status. Salaried employees earning below $58,656/year (2025) and performing non-exempt duties qualify for overtime. The test involves both salary and duties.
Generally yes. Federal law does not limit weekly hours for adults. However, overtime must be compensated properly. Some states have additional protections for specific industries.
