Frequently asked questions
Which overtime multiplier should I use?
Use the one in your contract or in your country's labour rules. Time-and-a-half (1.5×) is the most common baseline, double time (2×) applies on rest days or public holidays in many agreements, and 1.25× is common elsewhere. If you are unsure, check your payslip: divide your overtime line by your normal hourly rate.
Is overtime pay taxed more than normal pay?
Usually not more — it is simply added to your income for that period, which can push part of it into a higher bracket and make the payslip look heavily taxed. Over a full year, overtime is taxed at your normal marginal rates. Estimate the net effect with your effective rate in the Salary Calculator.
Should unpaid overtime be included here?
No — this calculator values paid overtime hours. If you work unpaid extra hours, the honest comparison is your effective hourly rate: divide your salary by your real hours using the Salary to Hourly Calculator. Seeing that number is often the clearest argument for change.
How many overtime hours can I legally work?
Limits vary widely by country and sector, and many places cap both weekly hours and annual overtime. This calculator has no legal limit built in — it will happily calculate 200 hours a month. Check your local rules before relying on an overtime figure for a budget.
