The overtime calculator shows your overtime earnings and total weekly pay in seconds. Enter your regular hourly rate, how many standard hours you worked, and how many overtime hours you put in — the calculator breaks out your regular pay, overtime pay, and combined total instantly. The most common use is verifying a pay stub. When a paycheck looks off, running your hours through this calculator confirms what you should have been paid before raising the issue with payroll. It is also useful before a busy period: knowing exactly how much a week of extra hours will earn helps you decide whether it is worth it financially and what tax bracket those hours might push you into. The overtime multiplier defaults to 1.5x (time-and-a-half), which is the US federal minimum under the Fair Labor Standards Act for non-exempt employees. Adjust it to 2x for double-time arrangements, or a custom rate if your employer uses a different premium for weekends, holidays, or shift differentials. All figures shown are gross pay before tax deductions.

How It Works
Total Pay = (Regular Hours × Rate) + (OT Hours × Rate × Multiplier)
Formula: Total Pay = (Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × Multiplier) Regular pay is straightforward: hours worked at your standard rate. Overtime pay applies the multiplier on top of your base rate for each overtime hour. The two are summed for your total weekly gross pay. Example: $20/hour, 40 regular hours, 8 overtime hours at 1.5x. Regular pay = 40 × $20 = $800 Overtime pay = 8 × $20 × 1.5 = $240 Total = $800 + $240 = $1,040 Under US federal law, the 40-hour threshold triggers overtime for most salaried and hourly non-exempt workers. Some states have stricter rules — California requires overtime pay for any hours beyond 8 in a single day, not just 40 in a week. Some professions (healthcare, transport, agriculture) operate under different FLSA exemptions. Always check your state's specific overtime rules and your employment agreement, as employer overtime policies can be more generous than the legal minimum but never less.
Frequently Asked Questions
What is the standard overtime rate?
In the United States, the Fair Labor Standards Act requires at least 1.5x (time-and-a-half) for hours worked beyond 40 per week for non-exempt employees. Some employers pay 2x (double time) for holidays, Sundays, or hours beyond 12 in a day. The multiplier slider in this calculator lets you use any rate your employer applies.
Does overtime kick in after 8 hours or 40 hours?
At the federal level, overtime kicks in after 40 hours in a workweek. California is the main exception: state law requires daily overtime after 8 hours in a day and double time after 12 hours, regardless of the weekly total. A handful of other states have similar daily overtime rules. Check your state labour department for the rule that applies to you.
Is overtime pay taxed at a higher rate?
Not by design — overtime is taxed at the same marginal rate as regular wages. However, earning overtime can push your total income into a higher tax bracket for that pay period, resulting in more tax withheld from that paycheck. The additional withholding is not a permanent penalty; it corrects at year-end when you file your tax return based on your total annual income.
What if my employer uses a different overtime multiplier?
Use the multiplier slider to set any rate between 1x and 3x. If you receive 1.75x for weekend shifts or 2x for public holidays, set the slider accordingly. For multiple overtime tiers in the same week (1.5x for hours 41–48, 2x beyond 48), run the calculator twice with each tier's hours and rate, then add the results.
Is the overtime calculator free?
Yes — free with no account needed. All calculations run in your browser and no data is stored. Use it to cross-check every pay stub or plan ahead for any upcoming busy period.
