How it works
An overtime calculator works out gross pay when some hours are paid at a premium rate, separating regular hours paid at your base rate from overtime hours paid at that rate multiplied by an uplift. It computes the two pay pools independently and adds them, so you see not just the total but how much of it came from the overtime premium. This split matters because overtime is where paychecks most often go wrong. Under the Fair Labor Standards Act, non-exempt US employees must receive at least one and a half times their regular rate for hours worked beyond forty in a workweek, and applying that only to the excess hours — never the whole week — is exactly the distinction an overtime calculator keeps straight. Getting it wrong under- or over-pays and can breach the law. The method mirrors how payroll is actually run: base hours at the base rate, premium hours at rate times multiplier. A multiplier of 1.5 is the familiar time and a half, while 2.0 is double time some employers pay on holidays. Hourly workers checking a paycheck, small-business owners running payroll, and managers costing a shift schedule all use an overtime calculator to confirm the premium is applied correctly to the right hours.
Total = regular hours × rate + overtime hours × rate × multiplier
Pay is built from two separate products: regular hours times the base rate, and overtime hours times the base rate times the multiplier. They are added for the total. The premium applies only to the overtime hours because those are the hours worked beyond the standard threshold — multiplying the whole week by 1.5 would wrongly pay a premium on ordinary hours the law treats as regular time.

Frequently asked questions
What is time and a half?
Time and a half means each overtime hour is paid at 1.5 times your normal hourly rate. At a $25 base rate, overtime hours are worth $37.50 each. Enter 1.5 as the multiplier to apply it. Under the Fair Labor Standards Act this is the federal minimum overtime premium for non-exempt employees working beyond forty hours in a workweek.
What overtime multiplier should I use?
For standard US overtime beyond forty hours a week, use 1.5. Some employers pay 2.0, known as double time, for holidays or hours past a daily threshold, and a few states such as California have their own daily overtime rules. Check your employment contract or state labor law, as the federal FLSA sets only the 1.5 floor and states may require more.
Does this include taxes and deductions?
No. The result is gross pay before income tax, Social Security, Medicare, benefits or any other withholding. Your actual take-home pay will be lower once those are applied. Use this figure to check that your employer calculated the correct gross amount, then compare net pay separately against your payslip's deductions.
How is overtime calculated over forty hours?
Under the FLSA, hours worked beyond forty in a single workweek are overtime and must be paid at your premium rate, while the first forty stay at the base rate. Enter forty as regular hours and the excess as overtime hours. The threshold is weekly, not daily, under federal law, so a long single day is not automatically overtime unless the weekly total exceeds forty.
Is salaried or exempt work eligible for overtime?
Not always. The FLSA exempts certain salaried executive, administrative and professional employees who meet specific duties tests and earn above a set salary threshold. Non-exempt employees, including most hourly workers, must receive overtime. If you are unsure of your status, check your job classification, because being paid a salary alone does not make a role exempt from overtime pay.
