All values are gross pay (before taxes and deductions). Overtime rules differ by country, state, and contract. This overtime calculator helps you estimate pay but does not replace legal or HR guidance.

How to calculate overtime pay

Overtime pay is usually calculated by applying a higher multiplier to hours worked beyond your regular schedule. A common structure is time-and-a-half (1.5×) for overtime and double-time (2×) for certain days or very long shifts.

This calculator uses the following general formula:

weekly gross pay = (regular hours × rate) + (OT hours × rate × OT multiplier) + (double-time hours × rate × DT multiplier)

You can change the multipliers to match your own policy. For example, you might use 1.25× for certain bonuses or 2.5× for holiday overtime.

Understanding time-and-a-half and double-time

Time-and-a-half (1.5×)

Time-and-a-half means you earn 1.5 times your regular hourly rate for each overtime hour. For example, if your base rate is $20/hour, time-and-a-half is $30/hour. Many employers apply this rate after 8 hours in a day or 40 hours in a week, depending on local laws.

Double-time (2×)

Double-time means you earn 2 times your regular hourly rate. Using the same example, a $20/hour base rate becomes $40/hour at double-time. Double-time is often used for holidays, rest-day work, or very long shifts beyond a certain threshold.

Overtime calculation examples

Here are a few quick overtime examples using common multipliers:

Scenario Breakdown Weekly gross
$20/hour, 40h regular + 5h OT @1.5× Regular: 40 × 20 = $800
OT: 5 × 20 × 1.5 = $150
$950
$30/hour, 38h regular + 4h DT @2× Regular: 38 × 30 = $1,140
DT: 4 × 30 × 2 = $240
$1,380
$18/hour, 35h regular + 3h OT @1.5× + 2h DT @2× Regular: 35 × 18 = $630
OT: 3 × 18 × 1.5 = $81
DT: 2 × 18 × 2 = $72
$783

Overtime for hourly vs salaried workers

Hourly employees

If you are paid hourly, this calculator can be used directly. Just enter:

  • Your base hourly rate
  • Your regular hours for the week
  • Your overtime hours and multipliers

The result shows how your total weekly pay changes when you add overtime and double-time.

Salaried employees

For salaried employees, overtime rules depend heavily on your classification and local law. Some salaried employees are not eligible for overtime at all, while others are.

If you want to understand the value of extra hours, you can:

This will not change your actual paycheck, but it helps you understand the effective hourly value of working longer weeks.

Overtime rules and limitations

Overtime regulation varies widely. Some places calculate overtime after 8 hours in a day, others after 40 hours in a week, and some use both daily and weekly thresholds. There may also be special rules for:

  • Night shifts or weekend work
  • Public holidays
  • On-call hours or standby time

This overtime calculator does not attempt to implement any specific legal rule. Instead, it gives you flexible input fields (hours and multipliers) so you can model your own situation. For precise legal entitlements, always refer to official labor law or speak with HR or a professional advisor.

Frequently asked questions

What if my overtime multiplier is not 1.5× or 2×?

No problem. Simply type your own multiplier in the OT or double-time fields. For example, you can use 1.25×, 1.75×, or any other rate specified in your employment contract.

Can I use this overtime calculator for different currencies?

Yes. Use the currency selector above the calculator to switch between USD, EUR, GBP, MAD, CAD, and AUD. The math is the same; only the currency symbol changes. If you need to convert between currencies, try the Currency Converter.

Does overtime always increase my annual pay?

Working overtime usually increases your weekly and annual gross income, but it also means more hours worked and potential fatigue. This tool focuses only on the numbers. It’s up to you to balance overtime earnings with time, rest, and long-term health.
