Convert hourly pay to monthly salary and back using the Danish norm of 37 hours = 160.33 hours a month, and see your new pay if you reduce or increase your hours in Denmark.
Danish rules
This calculator applies Danish law and Danish collective agreements. It is for employment in Denmark and does not reflect the rules of other countries.
Between 1 and 48 hours per week — e.g. 37, 37.5 or 40 for full time
The part-time salary calculator converts your pay when your weekly hours change — for example when you go down from 37 to 30 hours, or up from part-time to full-time. It is designed for monthly-paid employees (månedslønnede) working in Denmark and uses the usual Danish norms. You can start from your monthly salary or your hourly rate, and the result shows your new hourly rate, monthly salary and annual salary. If you enter the same number of hours twice, your pay is simply converted: from hourly rate to monthly salary, or from monthly salary to hourly rate.
Multiply the hourly rate by the number of hours per month. Full time at 37 hours a week — the norm in most Danish collective agreements (overenskomster) — is 160.33 hours per month, so an hourly rate of DKK 200 gives DKK 32,067 a month. If you work part-time, you find your hours per month by multiplying your weekly hours by 4.3333.
monthly salary = hourly rate × hours per week × 4.3333
| Hourly rate | Monthly salary at 37 h/week | Monthly salary at 30 h/week | Monthly salary at 25 h/week |
|---|---|---|---|
| DKK 150 | DKK 24,050 | DKK 19,500 | DKK 16,250 |
| DKK 160 | DKK 25,653 | DKK 20,800 | DKK 17,333 |
| DKK 180 | DKK 28,860 | DKK 23,400 | DKK 19,500 |
| DKK 200 | DKK 32,067 | DKK 26,000 | DKK 21,667 |
| DKK 220 | DKK 35,273 | DKK 28,600 | DKK 23,833 |
| DKK 250 | DKK 40,083 | DKK 32,500 | DKK 27,083 |
Basic pay before tax, excluding pension, supplements and overtime. Hours per month = 37 hours × 52 weeks ÷ 12 months ≈ 160.33.
Divide the monthly salary by your hours per month. If you work full time, divide by 160.33: a monthly salary of DKK 35,000 equals an hourly rate of DKK 218.30. If you work part-time, divide by your weekly hours × 4.3333 — DKK 30,000 for 30 hours a week is DKK 230.77 an hour.
hourly rate = monthly salary ÷ (hours per week × 4.3333)
In the calculator, choose Monthly salary under »What do you know?«, enter your hours in both hour fields and press Calculate — the hourly rate then appears in the result. If you want to compare two jobs with different working hours, the hourly rate gives the fairest picture; Compare job offers also includes pension and other benefits.
If you work 25 hours a week, that is 108.33 hours a month; 30 hours a week is 130.00 hours a month. The table shows what the most common weekly hours correspond to per month and per year, and what share of full time they represent.
| Hours per week | Hours per month | Hours per year | Share of full time |
|---|---|---|---|
| 37 hours | 160.33 | 1,924 | 100% |
| 35 hours | 151.67 | 1,820 | 95% |
| 32 hours | 138.67 | 1,664 | 86% |
| 30 hours | 130.00 | 1,560 | 81% |
| 28 hours | 121.33 | 1,456 | 76% |
| 25 hours | 108.33 | 1,300 | 68% |
| 20 hours | 86.67 | 1,040 | 54% |
| 15 hours | 65.00 | 780 | 41% |
| 10 hours | 43.33 | 520 | 27% |
Hours per year are 52 weeks before holidays and Danish public holidays (helligdage). Share of full time is based on 37 hours. You can find the actual number of working hours in a given year with Public holidays and working hours.
If you reduce your hours, your pay falls in the same proportion as your hours, while your hourly rate stays the same. New monthly salary = current monthly salary × (new hours ÷ current hours). So if you go from 37 to 30 hours, you get 81% of your previous salary.
An employee goes from 37 to 30 hours a week on a monthly salary of DKK 35,000.
35,000 × (30 ÷ 37) = DKK 28,378
An employee on DKK 210 an hour goes from 37 to 25 hours a week. The hourly rate is unchanged; 25 hours a week is 108.33 hours a month.
DKK 210 × 108.33 hours = DKK 22,750
A change in working hours must be notified in writing no later than the day the change takes effect (section 5 of the Danish Act on Employment Contracts, ansættelsesbevislovens § 5, Danish text). Also check whether the collective agreement (overenskomst) requires an agreement or notice.
If the reduction is not agreed but imposed, and it is substantial, it generally requires the employee’s notice period (opsigelsesvarsel).
Remember to adjust pension and supplements calculated as a percentage of basic pay. To see the change as a percentage, use the percentage calculator.
The calculator only shows basic pay. Pension, holiday pay (feriepenge) and supplements often follow your pay down — check them separately. Compare job offers includes pension, free-choice account (fritvalg) and bonus in the total value.
Talk to your shop steward (tillidsrepræsentant) or trade union before you accept a change in working hours — especially if you are employed under a collective agreement.
Get the changed working hours in writing, so there is no doubt about the terms.
