I set aside 30% for Income taxes, 6% State use tax, 3% Airbnb fee, $25/cleaning if I do it, or total charge if hiring outside help for it (usually more), along with consumables I buy for the place (TP, snacks, detergents, toiletries, cleaning supplies etc).
I don't look at it on a per-stay basis, but monthly (too hard to split those consumables up by stay). Once the deductions are taken out, I divide what's left by the estimated hours I spent on admin, laundry, greeting guests, etc. to get what is essentially my hourly rate. I've been happy with it, so I keep going!
