Overtime pay calculator

Calculate overtime earnings using a configurable multiplier (×1.25, ×1.5, ×2.0 or custom).

Fields marked with * are required.

Select the country to apply its legal overtime multipliers, or leave it empty to choose a manual multiplier.
Pay basis
Gross salary before deductions, used to derive the base hourly rate.
Usual hours per week; used to derive the base hourly rate.
Number of additional hours worked each week.
Manual multiplier
Used when no country is selected.

Calculate your base hourly rate, overtime rate and total weekly earnings with a configurable multiplier that fits your country or company rules.

Formula

Base hourly rate = (monthly salary × 12) ÷ (52 × weekly hours). Overtime rate = base hourly × multiplier. Weekly overtime pay = overtime rate × overtime hours. Total weekly earnings = (base hourly × regular hours) + overtime pay.

When is this useful?

Useful when estimating overtime pay for work schedules, negotiating overtime compensation, or comparing job offers that involve extra hours.

Worked example

Monthly salary: 1,000 currency units, weekly hours: 40
Base hourly rate ≈ 5.77
With a ×1.5 multiplier: overtime rate ≈ 8.65
6 overtime hours per week ≈ 51.92
Total weekly earnings ≈ 282.69

Assumptions

  • 52 weeks and 12 months per year.
  • The base hourly rate is derived only from the weekly hours you enter.
  • Results are weekly, not monthly.
  • Allowances, bonuses and other benefits are not included.
  • Overtime multipliers vary by country; check the rule that applies to you.
  • When a country is selected the legal multiplier for each overtime kind is applied.

Common mistakes

  • Using net salary instead of gross salary.
  • Assuming the base hourly rate does not depend on weekly working hours.
  • Forgetting that the result is weekly, not monthly.
  • Applying a fixed multiplier without checking local rules or your contract.

Frequently asked questions

How is the base hourly rate derived from a monthly salary?

The annual salary (monthly × 12) is divided by the total annual hours (52 weeks × weekly working hours).

Which multiplier should I use?

It depends on your country labour law and your employment agreement. Do not assume a single multiplier; check the rate that applies to you.

Does the result include taxes and deductions?

No. The result is an estimate based on the amount you enter, with no taxes or contributions deducted.

Can I get a monthly total?

Results are weekly. You can roughly estimate a month by multiplying the weekly figure by the number of weeks, but that is only an approximation.

Methodology and review

The calculator derives the base hourly rate from the monthly salary or the hourly rate you enter, then applies the multiplier to overtime hours. This page is reviewed periodically, and results depend on local labour laws and your contract, so confirm figures with your employer or the relevant authorities.

This result is an estimate for information purposes only and is not legal or financial advice. Always verify the overtime rules that apply in your country.
