Enter your hourly rate and hours to get overtime pay at time-and-a-half (or your multiplier) — plus total weekly pay.
What Is an Overtime Calculator?
An overtime calculator applies the premium rate to extra hours: $20/h × 10 h × 1.5 = $300.00 overtime pay, on top of $800.00 regular pay = $1,100.00 total. Time-and-a-half is the standard in the US (Fair Labor Standards Act) and common elsewhere; some contracts pay double time for weekends or holidays. Salaried and exempt workers are often excluded — check your contract and local law.
How to Use the Overtime Calculator
- Enter the hourly rate.
- Enter regular hours.
- Enter overtime hours.
- Pick the multiplier.
- Click “Calculate Pay”.
Formula
Regular = rate × regular hours. Overtime = rate × OT hours × multiplier. Total = regular + overtime.
Worked Example
$20/h, 40 regular h, 10 OT h at 1.5×: regular $800.00, overtime $300.00, total $1,100.00.
How It Works, In Plain Words
The tool splits the week into two piles of hours and prices them differently. Regular hours are paid at the plain rate: regular = rate × regular hours. Overtime hours are paid at the rate times the multiplier you pick: overtime = rate × OT hours × multiplier. The total is simply the two added together. The multiplier dropdown offers the three the benefits list names — 1.25×, 1.5× (time and a half, the default) and 2× (double time) — so the premium itself is an input, not an assumption: your contract or local law decides which applies, and the introduction notes time-and-a-half is the US standard under the Fair Labor Standards Act and common elsewhere.
The worked example shows the split clearly: at $20/h with 40 regular hours, regular pay is 20 × 40 = $800.00. The 10 overtime hours are priced at $20 × 1.5 = $30/h — the figure the first FAQ quotes — so overtime pay is 10 × $30 = $300.00, and the total is $800 + $300 = $1,100.00. Notice what the multiplier touches: only the overtime hours. The regular 40 are untouched, which is why the output shows the three lines separately — you can see the premium the extra hours earned instead of a single blended wage you would have to unpick.
Real-World Uses
An hourly worker checks a payslip: they enter their rate, the regular hours and the overtime hours from the rota, pick the contract’s multiplier, and compare the three output lines with the slip — the benefits list calls this out as the payroll-check use, and a mismatch is usually in the hours split rather than the arithmetic. A manager costing a busy weekend prices cover before approving it: the overtime line alone is the extra cost of opening, because the regular hours are already in the budget. A freelancer comparing a staff job offer converts the pitch into weekly terms: an offer built on long weeks looks different once the overtime hours are priced at 1.5× rather than folded silently into a salary, and the FAQ’s note that many salaried roles are exempt tells them exactly what to ask about.

Common Mistakes
- Applying the multiplier to ALL hours — only the overtime hours get it.
- Forgetting taxes: overtime is taxed like regular income.
- Assuming salaried workers get overtime — many are exempt.
Common Mistakes to Avoid
The mistakes list covers the big three: multiplying all hours instead of just the overtime hours, forgetting overtime is taxed like regular income, and assuming salaried staff qualify. In prose, watch three more. Do not guess the multiplier: 1.25×, 1.5× and 2× produce very different totals from identical hours, and the right one comes from your contract or local law, not from habit. Do not enter total hours in both boxes — the regular and overtime fields are separate piles, so hours counted twice are paid twice on screen. And do not treat the total as take-home pay: the tool shows gross figures before tax and deductions, which is why the tax FAQ below exists.
FAQ
What is time and a half on $20/h?
$30/h — 10 overtime hours = $300.00.
How is overtime pay calculated?
Hourly rate × overtime hours × multiplier (usually 1.5).
Is overtime taxed more?
No — it is taxed at the same rates as regular income (withholding may look higher on a big paycheck).
Who gets overtime?
Depends on country and contract — hourly non-exempt workers typically; many salaried roles are exempt.
What is double time?
2× the hourly rate — some contracts pay it for Sundays, holidays or very long shifts.
What would the worked example pay at double time?
Only the overtime line changes: $20/h × 10 h × 2 = $400.00, so the total becomes $800.00 + $400.00 = $1,200.00. Pick 2× (double time) in the dropdown to run it — the regular 40 hours stay at $800.00 whatever multiplier you choose.
My payslip splits the hours differently. Which box do I change?
Match the split, not the total. Regular hours are the hours paid at the plain rate and overtime hours only those paid at the premium; if your slip splits the same week differently, copy its split. The mistakes list warns that the classic error is applying the multiplier to all hours — the two-box layout exists to prevent exactly that.
