Overtime Pay Calculator
Calculate regular, overtime, and double-time earnings
Overtime Pay Calculator — what it does
Calculate a pay period from a regular hourly rate and hours, plus overtime and double-time hours at multipliers you set. It separates regular, overtime and double-time pay before totalling them, so a payslip can be checked line by line rather than argued about as one number.
When this tool helps
- Checking a payslip where overtime does not look like it was paid at the agreed rate.
- Estimating earnings for a week with significant overtime before it is worked.
- Costing a shift pattern for a manager planning weekend or holiday coverage.
How to use it
- Enter the regular hourly rate and regular hours.
- Enter overtime hours and the overtime multiplier.
- Enter double-time hours and multiplier if they apply.
- Calculate to see each pay component and the total.
Accuracy, limits, and good practice
- Overtime rules are legal requirements, not conventions: many jurisdictions mandate 1.5x beyond a weekly threshold, and contracts cannot go below the statutory floor.
- The threshold matters as much as the rate — whether overtime starts after 8 hours daily or 40 hours weekly changes the total substantially.
- Results are gross pay. Tax, social contributions and deductions come off afterwards, and overtime can push earnings into a higher withholding band.
Frequently asked questions
What multiplier should I use?
1.5 is the common statutory overtime rate and 2.0 the usual double-time rate, but check your contract and local law.
When does double time apply?
Typically on public holidays, on a seventh consecutive day, or beyond a daily hour threshold — the rules vary widely by jurisdiction.
Is salaried overtime included?
Salaried exempt roles often receive no overtime premium. This calculator assumes hourly-paid work.

加班薪資計算器能做什麼
依正常時薪與工時，加上你設定倍率的加班與雙倍時數，計算一個薪資期間的收入。它會先分開正常、加班與雙倍工時的薪資再加總，讓薪資單能逐項核對，而不是只對著一個總數爭論。
什麼時候用得上
- 核對加班費看起來不像是按約定倍率給付的薪資單。
- 在加班發生之前，先估算加班較多那一週的收入。
- 主管規劃週末或假日班表時，先估算人力成本。
使用步驟
- 輸入正常時薪與正常工時。
- 輸入加班時數與加班倍率。
- 若適用，輸入雙倍時數與倍率。
- 計算後查看各項薪資與總額。
精確度、限制與實務建議
- 加班規則是法律要求而非慣例：許多法域規定超過每週門檻須給 1.5 倍，契約不得低於法定下限。
- 門檻與倍率同樣重要——加班從每日 8 小時起算，還是每週 40 小時起算，總額差很多。
- 結果為稅前金額。所得稅、社會保險與各項扣除另計，加班還可能把收入推進更高的扣繳級距。
常見問題
倍率該填多少？
1.5 是常見的法定加班倍率，2.0 是常見的雙倍倍率，但仍請查閱契約與當地法規。
什麼時候適用雙倍？
通常是國定假日、連續第七個工作日，或超過某個每日時數門檻——各地規定差異很大。
月薪制的加班有算嗎？
月薪的責任制職位常無加班加給。本計算器假設的是時薪制工作。
