Method, assumptions and sources

Formulas

Hourly rate = monthly salary ÷ (weekly hours × 52 ÷ 12), or annual salary ÷ (weekly hours × 52)
Overtime pay = hours × hourly rate × multiplier (1.5 = time and a half, 2.0 = double time)
Night differential = night hours × hourly rate × differential %
Extra pay = overtime at both multipliers + night differential
Take-home extra = extra pay × (1 − estimated tax and deductions %)
Per year, if it repeats = extra pay × 52 (weekly) or × 12 (monthly)

Assumptions and limits

  • Universal estimate without the rules of any country: the multipliers, the night differential and the tax rate are typed by you.
  • Legal hour limits, overtime on a different base (for example including bonuses), weekend premiums and exact withholding rules are not included.
  • Estimate only, with no legal value; it does not replace your payslip. Labor and tax rules depend on your country, state and contract.

Frequently asked questions

How is overtime pay calculated?

Find your regular hourly rate, then multiply each overtime hour by that rate and by the overtime multiplier: 1.5 for time and a half, 2.0 for double time. For a salary, the hourly rate is the monthly salary divided by weekly hours × 52 ÷ 12, or the annual salary divided by weekly hours × 52.

How do I read the default example?

At $25 an hour and 40 hours a week, 8 overtime hours at 1.5× pay $300 and 2 hours at 2× pay $100: $400 of extra pay in the week, raising it from $1,000 to $1,400. With an estimated 20% tax on the extra, about $320 reaches your pocket. If it repeats every week, that is $20,800 a year before tax.

Who gets overtime and at what rate?

It depends on where you work. Many places pay at least time and a half after a set number of hours per day or week, some pay double time on holidays or rest days, and some salaried jobs are exempt. Check your employment contract, union agreement or your local labor authority.

What is a night shift differential?

An extra percentage paid for hours worked at night. In some countries it is required by law; in others it depends on the employer or the contract. Enter your rate, or 0 if you do not get one.

Why does the take-home part look smaller than on my regular pay?

Extra pay is added on top of your regular income, so it is usually taxed at your highest bracket. Use your marginal tax rate plus payroll deductions in the tax field. The real withholding on a single paycheck can differ and is often adjusted when you file your return.

What does the calculator leave out?

Legal limits on hours, overtime calculated on a different base (for example, including bonuses in the regular rate), shift premiums for weekends, and the exact tax withholding rules of your country. It is an estimate, not a payroll calculation.

When should I talk to someone?

If your overtime is not paid, is paid at the wrong rate or you are unsure whether you qualify, talk to your HR department, your union or your local labor authority. Keep a record of the hours you work.

How overtime and night pay are calculated

Overtime pay starts from your regular hourly rate. If you are paid by the hour, that is your rate. If you earn a salary, divide it by the hours you work: a monthly salary by weekly hours × 52 ÷ 12 (173.3 hours for a 40-hour week), or an annual salary by weekly hours × 52.

Time and a half and double time

Each overtime hour is paid at the regular rate times a multiplier. Time and a half (1.5×) is the most common; double time (2.0×) is often used for holidays, rest days or very long shifts. At $25 an hour, an overtime hour at 1.5× pays $37.50, and one at 2× pays $50. Who qualifies, after how many hours and at what rate depends on the country, state, union agreement and contract.

Night shift differential

Some jobs pay an extra percentage for night hours. With a 10% differential, each night hour at $25 earns $2.50 more. Enter the percentage that applies to you; it is added on top of regular or overtime pay.

What you actually keep

Extra pay sits on top of your regular income, so it is usually taxed at your highest bracket. Put your marginal rate plus payroll deductions in the tax field to see the take-home part. In the default example, $400 of extra pay in a week leaves about $320 after an estimated 20%.
