⏰ What is an Overtime Calculator?

Overtime pay is additional compensation paid when an employee works beyond their standard hours. Under the US Fair Labor Standards Act (FLSA), most non-exempt employees are entitled to at least 1.5 times their regular rate of pay for every hour worked beyond 40 in a single workweek. This is commonly called time-and-a-half. Some states and employment contracts provide more generous overtime rules, including double-time (2x) for extended workdays or seventh consecutive workdays.

This Overtime Calculator handles two common needs. The Pay Period OT mode calculates your gross pay for a specific week or biweekly pay period when you have worked both regular and overtime hours. It shows your regular pay, overtime pay, total gross pay, the overtime premium earned (the extra amount beyond what you would have earned at straight time), and your effective blended hourly rate. The Annual Overtime Earnings mode lets you project total yearly income when you consistently work overtime each week, which is useful for budgeting or comparing job offers that include expected overtime.

Understanding overtime math matters beyond the paycheck itself. Overtime pay is taxable income at your ordinary income tax rate, so a pay period with heavy overtime can result in higher withholding. Lenders often require a two-year overtime history before including it in qualifying income for mortgages. And for workers considering whether to take on extra shifts, seeing the exact dollar value of each overtime hour versus the fatigue trade-off helps make informed decisions.

The calculator also displays a note about FLSA compliance. If you enter a multiplier below 1.5x and you have overtime hours in a workweek where total hours exceed 40, the calculator will flag that this may not meet federal minimum standards. This is helpful for employees who suspect they may be underpaid for overtime or for payroll professionals verifying calculations.

📐 Formula

Total Pay  =  (Regular Rate × Regular Hours) + (Regular Rate × OT Multiplier × OT Hours)
Regular Rate = base hourly rate of pay
Regular Hours = hours worked up to 40 per workweek
OT Multiplier = 1.5 for time-and-a-half, 2.0 for double time
OT Hours = hours worked beyond 40 per workweek
OT Premium = (OT Multiplier − 1) × Regular Rate × OT Hours
Example: $20/hr regular rate, 40 regular hours, 8 OT hours at 1.5x: ($20 × 40) + ($20 × 1.5 × 8) = $800 + $240 = $1,040

📖 How to Use This Calculator

Steps

1
Select Pay Period or Annual mode - Use Pay Period OT for a specific paycheck calculation. Use Annual OT Earnings to project full-year income with recurring overtime.
2
Enter your regular hourly rate - Type your base pay rate or use the slider. This is your rate before any overtime multiplier is applied.
3
Set regular and overtime hours - Enter hours worked at the regular rate (typically 40 for a full workweek) and additional overtime hours worked on top.
4
Choose your OT multiplier - Select 1.5x (federal FLSA standard), 2.0x (double time), or enter a custom rate to match your contract or state law.
5
Review results - See regular pay, overtime pay, total gross, OT premium, and effective blended hourly rate. Check the FLSA compliance note if relevant.

💡 Example Calculations

Example 1 - Warehouse Worker at $18/hour, 10 Hours OT

Weekly pay period with 40 regular hours and 10 overtime hours at 1.5x

1
Regular pay = $18 × 40 = $720.00
2
OT rate = $18 × 1.5 = $27.00/hour. OT pay = $27 × 10 = $270.00
3
Total gross pay = $720 + $270 = $990.00. OT premium earned = $270 - $180 = $90.00
Weekly Total = $990.00

Example 2 - IT Professional at $45/hour, Annual OT Projection

40 regular hours + 8 OT hours per week for 50 weeks at 1.5x

1
Annual regular pay = $45 × 40 × 50 = $90,000
2
OT rate = $45 × 1.5 = $67.50/hour. Annual OT = $67.50 × 8 × 50 = $27,000
3
Total annual earnings = $90,000 + $27,000 = $117,000. Monthly = $9,750
Annual Total = $117,000

Example 3 - Nurse at $35/hour, Double Time on Weekend Shift

Biweekly period: 80 regular hours + 16 OT hours at 2.0x double time

1
Regular pay (2 weeks) = $35 × 80 = $2,800.00
2
Double-time rate = $35 × 2.0 = $70.00/hour. OT pay = $70 × 16 = $1,120.00
3
Biweekly total = $2,800 + $1,120 = $3,920.00. Effective blended rate = $3,920 ÷ 96 hours = $40.83/hour
Biweekly Total = $3,920.00

Example 4 - Retail Associate, 5 Weekly OT Hours All Year

$15/hour, 40 regular + 5 OT hours/week at 1.5x for 52 weeks

1
Annual base (no OT) = $15 × 40 × 52 = $31,200
2
Annual OT = $15 × 1.5 × 5 × 52 = $5,850
3
Total annual earnings = $31,200 + $5,850 = $37,050. That is an 18.75% increase from working just 5 extra hours weekly.
Annual Total = $37,050

❓ Frequently Asked Questions

How do I calculate overtime pay at time-and-a-half?+
Multiply your regular hourly rate by 1.5 to get the overtime rate. Then multiply by overtime hours. Example: $20/hour regular rate, 8 OT hours. OT rate = $20 x 1.5 = $30/hour. OT pay = $30 x 8 = $240. Add regular pay: $20 x 40 = $800. Total gross = $1,040 for the week.
What is the FLSA rule for overtime pay?+
The Fair Labor Standards Act requires non-exempt employees to receive at least 1.5x their regular rate for all hours over 40 in a workweek. It applies to most private-sector workers. Exempt employees (salaried professionals earning over $684/week meeting specific duties tests) are excluded. The FLSA workweek is any fixed 168-hour period, not necessarily Monday to Sunday.
Does overtime reset weekly or biweekly?+
Under FLSA, overtime is calculated per individual workweek, not per pay period. Even if you are paid biweekly, each 40-hour workweek is evaluated independently. Employers cannot average two weeks to avoid overtime. If you work 30 hours in week one and 50 in week two, you earned 10 hours of overtime in week two regardless of the biweekly pay schedule.
Is overtime taxed at a higher rate?+
Overtime pay is taxed as ordinary income at your marginal rate, the same as regular wages. However, because a single large paycheck can push the estimated annual income into a higher withholding bracket, your employer may withhold more for that check. This corrects itself at year-end filing. You do not permanently pay a higher tax rate on overtime; your total tax liability is based on annual income.
What is the difference between time-and-a-half and double time?+
Time-and-a-half is 1.5x your regular rate, required federally for hours over 40 per week. Double time is 2x your regular rate, mandated in California for hours over 12 in a single day and all hours on the seventh consecutive workday in a week. Federal law does not require double time. It is often negotiated in union contracts or required by some state laws.
Are salaried workers entitled to overtime?+
Salaried non-exempt employees earning under $684/week ($35,568/year as of 2024) must receive overtime at 1.5x their effective hourly rate. Salaried exempt employees (earning above the threshold and meeting executive, administrative, or professional duties tests) are not entitled to overtime under FLSA. Many workers are misclassified as exempt when they should not be.
How is overtime calculated for employees who earn bonuses?+
Non-discretionary bonuses (production bonuses, attendance bonuses, guaranteed bonuses) must be included in the regular rate of pay for overtime calculation. This increases the base rate and therefore the OT rate. Discretionary bonuses (year-end gifts, bonuses not tied to a specific formula) can be excluded. The FLSA requires employers to recalculate OT if a bonus is paid retroactively for a period that included overtime.
How much extra do I earn working 10 hours of overtime per week?+
At $20/hour with 10 weekly OT hours at 1.5x for 52 weeks: OT rate = $30/hour. Annual OT earnings = $30 x 10 x 52 = $15,600. Annual base (no OT) = $20 x 40 x 52 = $41,600. Total annual with OT = $57,200. Working 10 extra hours per week increases annual earnings by 37.5%. Use the Annual OT Earnings mode to model your specific rate.
Can my employer give me comp time instead of overtime pay?+
In the private sector, FLSA generally does not allow compensatory time off in lieu of cash overtime pay for non-exempt employees. State and local government employers may use comp time under specific conditions. Some employers use flex scheduling (fewer hours another week) to keep weekly totals under 40, which is legal. But if hours in any single workweek exceed 40, cash overtime is required.
What is the effective hourly rate when working overtime?+
The effective (blended) hourly rate is total gross pay divided by total hours worked. For a worker at $20/hour working 40 regular + 8 OT hours at 1.5x: gross = ($20 x 40) + ($30 x 8) = $800 + $240 = $1,040. Effective rate = $1,040 / 48 hours = $21.67/hour. This is always between your regular rate and your OT rate, weighted by the proportion of each type of hour.
Does this overtime calculator work for non-US workers?+
Yes. The overtime pay formula (Regular Rate x Multiplier x OT Hours) is universal. You can enter any custom multiplier to match your local law or employment agreement. The FLSA compliance note is US-specific, but the calculation itself works for any country's overtime rules. Use the currency selector to display results in your preferred currency symbol.
