Overtime Pay
What is a Overtime Pay?
An overtime pay calculator works out exactly how much you earn when you work beyond your standard weekly hours. Enter your hourly rate, your regular weekly hours, the number of overtime hours you worked, and the overtime multiplier that applies, and the calculator returns your overtime pay, total weekly pay, regular pay, and your effective overtime hourly rate.
Overtime rules exist in most countries to compensate workers for time spent beyond the standard working week. In the United States, the Fair Labor Standards Act (FLSA) requires most non-exempt employees to receive at least 1.5 times their regular rate, commonly called "time and a half", for every hour worked beyond 40 in a week. Some states impose stricter rules: California, for instance, requires daily overtime (1.5× after 8 hours in a day, 2× after 12), not just weekly.
Understanding your overtime entitlements protects you from underpayment and helps you plan your income. If you work irregular hours or take on extra shifts, the difference between regular and overtime pay can add up quickly. A $20/hr worker clocking 10 hours of weekly overtime at 1.5× earns an additional $300 per week, over $15,000 per year more than the regular rate alone would suggest.
The overtime multiplier itself varies by situation. The most common scenarios are 1.5× (time and a half), 2× (double time, common on public holidays), and 2.5× (double time and a half, used in some collective bargaining agreements). Our calculator supports all three so you can model whichever rate applies to your specific situation.
To estimate your annualised income including overtime, multiply your typical total weekly pay by 52, or use our Salary Calculator to convert weekly earnings into an annual figure.
Why Use an Overtime Pay Calculator?
Manual overtime arithmetic is error-prone, especially when your hours vary week to week. Employers are required by law to pay correctly, but errors, whether accidental or intentional, do occur. Having an independent calculation gives you a clear benchmark to check your pay slip.
Verify your pay slip instantly. If your employer lists your overtime hours but the total pay looks off, entering the same numbers into the calculator tells you what you should have received. Discrepancies are worth raising promptly, since wage theft, including unpaid overtime, is one of the most common labour violations.
Plan your earnings for variable schedules. If you are offered extra shifts, knowing exactly how much you will earn for each overtime hour helps you decide whether it is worth it after tax and other considerations. The marginal value of an overtime hour is always higher than your regular rate, making overtime one of the fastest ways to boost short-term earnings.
Model different overtime scenarios. The calculator lets you adjust overtime hours from 0 to 60 with a slider, so you can see how your total weekly pay changes at 5 hours, 10 hours, or 20 hours of overtime. This is particularly useful for workers in industries like hospitality, healthcare, and logistics where overtime availability changes weekly.
Compare regular vs overtime compensation. Use the calculator alongside our Time Card Calculator to track total hours, then run the overtime calculation to split those hours into regular and OT pay with precision.
Who Should Use This Calculator?
Hourly workers in shift-based industries, hospitality, healthcare, manufacturing, logistics, and retail, are the primary users. These sectors routinely schedule overtime, and individual workers often need to verify their pay against hours logged. Knowing the formula removes any ambiguity when checking a pay slip.
Employees tracking their own hours who log overtime on an informal basis will find the calculator useful for projecting earnings before the pay period closes. If you know you have worked 12 extra hours this week, entering those numbers immediately shows the expected addition to your cheque.
Job seekers comparing hourly offers can use the calculator to evaluate job offers that include different base rates and typical overtime hours. An offer of $18/hr with regular 10-hour weekly overtime may pay more than $22/hr with no overtime, depending on the multiplier.
Small business owners and managers who calculate employee overtime manually, or want to sanity-check their payroll software, can use the calculator to verify individual pay computations. Pair it with our Commission Calculator if your staff earn a combination of hourly pay and commission.
International workers can use the calculator with any currency, simply ignore the $ symbol and treat the input as your local currency. The formula is identical regardless of currency.
What Insights Does the Overtime Pay Calculator Give You?
Overtime Pay is the headline output, the total additional earnings from all overtime hours worked at the elevated rate. This is the amount your overtime hours contribute above and beyond your regular weekly pay. For most users, this is the figure they are trying to confirm against their pay slip.
Total Weekly Pay shows your complete weekly gross earnings: regular pay plus overtime pay combined. This is the gross figure before income tax, pension contributions, or other deductions. For tax planning, multiply this by 52 to estimate annual gross income, then refer to your jurisdiction's income tax tables.
Regular Pay isolates your earnings for your standard working hours alone. Seeing this separately makes clear how much of your total pay comes from baseline hours versus overtime, a useful split if you are evaluating whether a role's base rate is competitive independent of overtime availability.
Overtime Hourly Rate shows your effective hourly rate during overtime hours. At 1.5×, a $20/hr worker earns $30/hr in overtime. At 2×, that jumps to $40/hr. Knowing this rate in dollar terms (rather than as a multiplier) makes it easy to compare against the effective hourly rate of a second job or freelance work you might consider instead.
How to use this Overtime Pay calculator
Enter your Hourly Rate, use your gross (pre-tax) hourly rate as it appears on your employment contract or pay slip. If you are a salaried employee trying to calculate overtime entitlement, divide your weekly salary by your contracted weekly hours to get an equivalent hourly rate.
Set Regular Hours Per Week, the number of hours in your standard working week before overtime kicks in. For most full-time non-exempt workers in the US this is 40 hours under federal law, though your state or employment contract may set a lower daily threshold. Adjust the slider to match.
Enter Overtime Hours Worked, the total extra hours worked beyond your regular threshold this week. If you are projecting rather than calculating a completed week, use your expected or typical overtime hours.
Select your Overtime Rate, choose 1.5× (time and a half) for standard US and Australian overtime, 2× (double time) for holiday or heavy-OT scenarios, or 2.5× (double time and a half) if specified in your contract. If unsure, check your employment contract or ask your payroll department.
Review the results, compare Overtime Pay against your pay slip. If Total Weekly Pay differs from what you received, check whether your employer is applying a different threshold, a different multiplier, or deducting something before the final figure.

Formula & Methodology
The overtime pay calculation has three steps: Step 1, Regular Pay Regular Pay = Hourly Rate × Regular Hours Step 2, Overtime Pay Overtime Hourly Rate = Hourly Rate × Overtime Multiplier Overtime Pay = Overtime Hourly Rate × Overtime Hours Step 3, Total Weekly Pay Total Weekly Pay = Regular Pay + Overtime Pay Variable definitions: - Hourly Rate, gross pay per hour as per employment contract - Regular Hours, contracted standard weekly hours (threshold before OT applies) - Overtime Multiplier, the rate applied to overtime hours (1.5, 2.0, or 2.5) - Overtime Hours, hours worked beyond the regular threshold this week Worked example: - Hourly Rate: $20/hr - Regular Hours: 40 hrs/week - Overtime Hours: 10 hrs - Overtime Multiplier: 1.5× Regular Pay = $20 × 40 = $800 Overtime Rate = $20 × 1.5 = $30/hr Overtime Pay = $30 × 10 = $300 Total Weekly Pay = $800 + $300 = $1,100 Annualised (÷ 52 weeks) = $1,100 × 52 = $57,200/year Assumptions: The calculator computes gross pay before income tax, national insurance, pension contributions, or other deductions. It applies a single overtime multiplier to all overtime hours, if your agreement uses a tiered structure (1.5× for hours 41–48, 2× for hours above 48), calculate each tier separately and add the results. The regular hours threshold defaults to 40 per week in line with US FLSA standards; adjust to match your local or contractual threshold. To estimate your annual take-home pay, use our Salary Calculator after obtaining your total weekly gross figure.
