Overtime Calculator
Calculate regular pay, overtime pay rates, and effective hourly wage rates.
Tracking work hours, timesheets, and paycheck calculations requires a clear understanding of US payroll standards. The Overtime Calculator helps employees, contractors, and business owners estimate earnings, billable hours, and paid time off (PTO) accruals.
Whether you are calculating regular wages, estimating overtime pay in compliance with the Fair Labor Standards Act (FLSA), or checking meeting costs, this tool provides instant estimates. All inputs are evaluated locally in your browser sandbox, keeping your business data private.
Overtime Wage Details
Calculate how extra hours worked at standard multipliers impact your total paycheck earnings.
Pay Projections
Breakdown of gross pay, overtime wages, and effective hourly returns.
Enter hourly rates and overtime hours to calculate pay projections.
How to Use the Overtime Calculator
Enter your work hours and wages parameters in the input fields. For timesheet hours, enter your clock-in and clock-out times alongside unpaid breaks. For salary and overtime paychecks, enter your base hourly pay rate, pay frequency (such as weekly or bi-weekly), and hours worked.
Click the "Calculate" button to process your hours or wages. The tool displays your gross wages, overtime premiums, and total billable hours in the results card. You can reset the form to start a new period at any time.
Formula & Calculation Logic
This tool uses standard payroll arithmetic. For overtime calculations under US Federal FLSA rules, hours worked over 40 in a single workweek are multiplied by 1.5 times the employee's regular hourly wage rate:
Gross Pay = (Regular Hours * Rate) + (Overtime Hours * Rate * 1.5)
where hours worked over 40 in a single week are isolated and scaled by the 1.5 time-and-a-half wage factor. Salary conversions annualize earnings by multiplying paycheck totals by pay frequencies (e.g. 26 bi-weekly periods or 12 monthly periods). PTO accruals are computed based on hours worked and annual allotment rates..

Real Example Calculation
Let's look at a realistic work scenario. Suppose: calculating gross pay including time-and-a-half overtime pay.
- Test Scenario: calculating gross pay including time-and-a-half overtime pay
- Test Inputs: Regular Hourly Rate: $20/hr, Total Hours Worked: 48 hours (8 hours overtime)
Adding these amounts together yields a total output of . This results in This results in under FLSA guidelines, hourly employees must earn 1.5 times their regular rate for hours worked over 40. This tool estimates those payments accurately. This illustrates the impact of regular and overtime rates on take-home pay before tax withholding deductions are applied.
Frequently Asked Questions
How is overtime pay calculated in the United States?
Under the federal Fair Labor Standards Act (FLSA), non-exempt employees must receive 1.5 times their regular hourly rate ("time and a half") for all hours worked over 40 in a single workweek. For example, if your regular rate is $20/hour, your overtime rate is $30/hour. Some states have additional overtime rules — California, for instance, also requires 1.5x pay for hours over 8 in a single day.
Does every American worker qualify for overtime pay?
No — the FLSA divides workers into "exempt" and "non-exempt." Non-exempt workers (most hourly and some salaried workers earning below $684/week as of the current federal threshold) must receive overtime pay. Exempt employees (executives, professionals, administrators earning above the salary threshold) are not entitled to overtime under federal law. Some states have higher salary thresholds.
What is double-time pay and when does it apply in the US?
Double time (2x your regular rate) is not required under federal law but is required in some states. California mandates double time for hours over 12 in a single workday and for all hours on the 7th consecutive day of a workweek. Many employers also voluntarily offer double time for holidays as a company policy, even when not legally required.
How do I calculate overtime for a salaried non-exempt employee?
Divide the weekly salary by the number of hours the salary covers (typically 40 hours) to find the regular hourly rate. Then pay 0.5x that rate for each overtime hour (the salary already covers the 1.0x portion). For example, a $1,000/week salary = $25/hour. Each overtime hour adds $12.50 (the additional 0.5x). This is called the "fluctuating workweek" method.
Which states have stricter overtime laws than federal requirements?
California has the most extensive overtime protections: 1.5x for daily hours over 8, double-time for hours over 12, and additional protections for the 7th day. Alaska, Nevada, and Colorado also have daily overtime rules. Always check your state's Department of Labor website, as state law applies when it's more generous than federal law.
Does overtime apply to weekend or holiday work under US law?
Under federal FLSA, overtime is based on hours worked in a workweek (typically Sunday–Saturday), NOT on the specific day of the week. Working on a Saturday or holiday does NOT automatically trigger overtime — it's only when total weekly hours exceed 40. However, many employers pay a holiday premium (time and a half or double time) as a company policy.
How does overtime affect my annual salary and taxes?
Overtime pay is taxed as regular income at your marginal federal rate. Higher overtime earnings could push some of your income into a higher tax bracket (though only the excess amount is taxed at the higher rate). Social Security tax also applies on overtime wages up to the annual wage base.

How accurate is this overtime calculator for US workers?
Our calculator uses the standard FLSA formula for federal overtime compliance. It calculates both regular and overtime hours based on your inputs and applies the applicable multiplier (1.5x or your entered rate). For workers in states with daily overtime (like California) or special industry rules, verify with your state's labor board, as results may differ from federal-only calculations.
