An Airbnb revenue forecast is a month-by-month projection of occupancy, ADR and revenue for one property, set beside comparable listings. Buyers use it to test a purchase, operators use it to check an arbitrage lease, and hosts use it to set targets for a live listing.
What I plan around in Leipzig: the Leipzig Book Fair; the Wave-Gotik-Treffen; Bach heritage and the Bachfest; the Plagwitz creative scene. Guests I price for: festival crowds and cultural travellers on 2 to 3 night stays in the Zentrum and the creative Plagwitz district. Where I start: distinct festival spikes across the year rather than a summer peak, trade-fair and concert demand, and Saxon registration and tourist-tax rules.
In PriceLabs or Wheelhouse I load Leipzig's festival and fair dates as custom events with their own minimum stays, and I separate weekday business demand from weekend culture guests. Your Airbnb, Booking.com and Vrbo listings then move together, so the Pentecost weekend is never sold cheaply on one channel.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Leipzig.
