to be eligible for Unemployment benefits ("Dagpenge") the 2 main requirements are:
- You must have been of an A-kasse for at least 1 year (you meet this requirement).
- You must have earned at least DKK DKK 228,348 during the last 3 years.
However about the second requirement - have earned DKK 228,348 - you must be aware that only income obtained during membership periods of an A-kasse can be included.
And regardless of what your monthly income is, you can only count a maximum of DKK 19,029 per month.
This means that regardless of how high salary you have, you always need to have been working for at least 1 year for being eligible for Unemployment benefits ("Dagpenge"). 12x19,029=228,348.
It is not correct - as you say - that you must have 12 months with income more than DKK 19,029. The DKK 19,029 is the maximum you can include in the calculation of DKK 228,348 every month.
If you earn less than DKK 19,029 in some months it means that it will take longer time for you to qualify for Unemployment benefits. Because it will take more than 12 months to reach the income requirement of DKK 228,348.
So in your case the problem seem not to be your income. You have earned more than DKK 228,348 during the last 3 years, also when you count a maximum of DKK 19,029 per month.
But your problem may be that only income obtained during periods where you have been member of an A-kasse can be counted.
So to qualify for Dagpenge, you must have earned DKK 228,348 since your membership started (27.02.2017).
