The first two tabs makes it possible to calculate your expected net salary, and tax, no matter if you're paid monthly or hourly, according to Danish standards. In the last tab you can get any amount Incl. and Excl. VAT, aswell as see what VAT amounts at.

Monthly Wage & Hourly Wage
Especially useful for interns and students abroad, for easy calculations of net salary.
There's a tab for Monthly Wage/ Biweekly Wage - Multiply if you got Biweekly Wage - and a seperate tab for Hourly Wage
If you're paid hourly, and get additional pay for skewed work time, input your average hourly salary, for the most accurate result

Just from informations found on your payslip or SKAT's website, the app can show you, your expected net salary, and how much you pay in tax.
There's even an input field for miscellaneous, which can be used for Eg. an extended health insurance or if you're part of a staff association at your work.
It's possible to calculate both your main income, and b-income, aswell as remove AM-TAX

VAT
Very usefull Eg. as a company that just got an offer for good or a job, and want to get the offer Incl/Excl Danish VAT.
All you need to do it input either an amount Incl. or Excl. VAT, and you'll get shown the opposite value, aswell as a calculation for how much VAT amounts at.
