@Chris11539
When i look at your listing i noticed the amounts you mentioned can not be for "a couple of month's ", as it seems more likely the price for 1 month. I see the Airbnb Guest service fee is appr. 11% (long term stay tarif) and the taxes is appr the same percentage. Also there is a cleaning fee. So the figures you mentioned seems rather correct.
Please note, besides what @Sarah977 already mentioned, you can goto to your calender when managing the listing, select the time period , choose "price calculator" and see exactly all amounts guest would be charged and what you would earn.
best regards,
