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 Normandy: D-Day landing beaches; Deauville American Film Festival; Etretat chalk cliffs; Mont-Saint-Michel. Guests I price for: history travellers and Paris weekenders on 2 to 5 night stays in Deauville, Honfleur and the landing-beach villages. Where I start: commemoration and film-festival premiums layered on a Paris-weekend base, seasonal coastal minimum stays, and French meuble de tourisme registration.
Together we configure PriceLabs or Wheelhouse with events for June commemorations and September's film festival, weekend rules for Paris visitors and weekly stays at the coast in summer. Your Booking.com, Vrbo and Abritel listings follow the same rules, so guests see one consistent offer.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Normandy.
