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 Paris: Fashion Weeks in March, June, September and October; Roland-Garros in late May; Trade shows at Porte de Versailles; Christmas and New Year. Guests I price for: Couples and small families from the US, UK and Asia staying 3 to 6 nights in central arrondissements. Where I start: Arrondissement-level benchmarks, trade-show and fashion-week premiums, and strategies that fit the 120-night primary-residence limit and registration rules.
In PriceLabs or Wheelhouse we load trade fairs, fashion and sporting weeks as events, set rules that protect your capped nights for the best dates, and keep rates realistic in early August. Booking.com, Vrbo and Abritel follow the same plan, with registration numbers on every listing.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Paris.
