You can use the price calculator (in the calender) to see detailed calculations.
I see on your lisitng the Airbnb service fee is approx 17% (incl.VAT) en cleanig fee is indeed 50,-
So to make it approx 600,- in total should be: 462,- + 50,- + 17%
You can also set the guest a special offer (must include the cleaning fee) or correct a normal booking afterwards by the "change" option and amend the price in the change form..
