@Barbara2579 as @Colleen253 has provided a link to the answer, I'm rather superfluous here!
At the moment, most Hosts' are charged a Service Fee of 3% (by Airbnb), but the cleaning charge paid by the Guests to Airbnb is then PAID TO the Host, NOT deducted from the amount s/he receives.
As far as I'm aware, the only other deduction that might appear amongst the details of a "Host's Payout", is where a "Promotion" may have been offered (and included within the word "Promotion" as we discovered earlier this year, are also any discounts offered when Guests' opt for a non-refundable cancellation policy) qv. https://www.airbnb.co.uk/help/article/2600/offer-a-nonrefundable-option
Hope that, on top of what @Colleen253 has already advised, might be of some help to you.
