Norway Overtime Pay Calculator 2026

Overtime in Norway (overtid) is work beyond the normal working time limits in the Working Environment Act (arbeidsmiljøloven): 9 hours in 24 hours and 40 hours in 7 days. For every overtime hour you are paid your normal hourly wage plus a supplement (overtidstillegg) of at least 40%. Many collective agreements (tariffavtaler) pay more. This calculator turns your annual salary or hourly wage into gross overtime pay, works out how much tax comes off, and compares being paid with taking the hours as time off.

How overtime pay is calculated

• Hourly wage = annual salary divided by a divisor, for example 1,950 or 1,850 hours
• Pay per overtime hour = hourly wage x (1 + supplement), so x 1.4, x 1.5 or x 2
• Gross overtime pay = pay per overtime hour x number of hours
• Net overtime pay = gross overtime pay minus the tax on it, calculated at your marginal tax rate

Worked example: NOK 600,000 a year

You earn NOK 600,000 a year and work 10 hours of overtime at a 50% supplement. With a divisor of 1,950 your hourly wage is NOK 307.69, and each overtime hour pays NOK 461.54. That gives NOK 4,615 gross, of which NOK 1,538 is the supplement itself. Tax on the overtime is NOK 1,551 (33.6%), so you keep NOK 3,065. If your employer uses the divisor 1,850, as central and local government do, the same hours give NOK 4,865 gross and NOK 3,230 net.

Pay per overtime hour by annual salary

The table shows gross pay for one overtime hour with a divisor of 1,950. The last column shows a 50% supplement with a divisor of 1,850.

40%, 50% or 100%?

Only 40% is set by law (Working Environment Act section 10-6, eleventh paragraph). That is the floor, and it is what you get if you have no collective agreement and nothing better in your contract. The 50%, 100% and 133 1/3% rates come from collective agreements, not from the law. The central government agreement, for example, defines an overtime supplement of 50% and an increased supplement of 100%, which applies to overtime between 20:00 and 06:00 and on Saturdays, Sundays and public holidays. In local government (KS), 100% applies between 21:00 and 06:00 and on Saturdays and Sundays, and the agreement gives 133 1/3% on public and religious holidays. So the evening rate starts at 20:00 in central government and at 21:00 in KS. Both agreements calculate the hourly wage as annual pay divided by 1,850 unless agreed otherwise. If your contract says nothing about the rate, the legal minimum applies. Always check the rate in your own contract or collective agreement, because this calculator cannot know it.

Paid out or time off?

If you and your employer agree in writing, you can take overtime hours as time off (avspasering). The hours come back one for one, but the supplement is still paid out. In the example above you get NOK 3,065 after tax if the hours are paid out. If you take them as time off, you get 10 hours off plus NOK 1,022 after tax. The 10 hours off therefore cost you NOK 2,043 after tax. The higher your marginal tax rate, the cheaper the time off becomes, because more of the payment would go to tax anyway.

Tax on overtime

Overtime is ordinary salary income. It is taxed with 22% tax on ordinary income, the national insurance contribution (trygdeavgift) of 7.6% and bracket tax (trinnskatt). The calculator works out the tax as the difference between your total tax with and without the overtime, using the 2026 rates. That stays correct even when the overtime pushes you into a higher bracket. The tax withheld on your payslip can be higher or lower in the month the overtime is paid, but it evens out when the tax return is settled. For the full picture of your salary after tax, use the Norway income tax calculator. Overtime also counts towards your holiday pay (feriepenger) the following year.

How much overtime is allowed

*Only in a workplace bound by a collective agreement, with a written agreement between the employer and the employee representatives. Total working time including overtime cannot exceed 13 hours in 24 hours, or 48 hours a week on average over 8 weeks. Overtime must be ordered or approved by the employer and only be used for a particular and time-limited need.

If you have just moved to Norway

The working time rules cover everyone who works in Norway, including foreign employees, seasonal workers and posted workers. You are entitled to a written employment contract, and it should state your hours and how overtime is paid. Employees in senior or particularly independent posts are outside the working time rules, so they have no statutory right to overtime pay, although many still get it by agreement. If your rate looks too low, ask your employer or your trade union first. Norway has no general minimum wage, but a few industries have one, see the Norway minimum wage guide.

What this calculator does not cover

It uses the divisor and supplement you enter, and does not know your collective agreement, shift or on-call allowances, or night and weekend supplements that are paid on top of ordinary hours. Tax is estimated with the standard deduction and no other deductions. It does not model foreign income, the tax rules for non-residents or the northern Norway tax zone.
