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 Québec City: Québec Winter Carnival; Festival d'été in July; Old Québec and cruise calls; Christmas markets. Guests I price for: US and Canadian couples on 2 to 4 night stays. Where I start: Festival premiums, winter carnival pricing, and CITQ-compliant positioning.
For hosts I set up your pricing tool with named events for the Carnival, Festival d'été and the Christmas market, plus floors that keep spring and November realistic. I also make sure the French and English versions of the listing carry identical rules.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Québec City.
