@davide one big mac

In switzerland the normal rate for a company/freelance work is about CHF/$ 90 to 140 an hour.

For employment it's around 38 francs per hour or CHF 6000 a month.

If you want to find out what it costs to do run a freelance business I can recommend you this video. It's for photographers but the principle applies to every business.

The best way to work out what to charge is to know how much you need monthly. Then depending on how many projects you have look at the time you have estimated for each (be fucking careful here everyone underestimates).

Then to get your absolute minimum hour figure divide the total money needed per month by your estimate it should give you a base line figure to work from. Then adjust that till you're happy.

Cover your expenses! 😊😊
