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 Myrtle Beach: Summer beach season; Golf packages in spring and autumn; Bike weeks in May; Carolina Country Music Fest. Guests I price for: Drive-to families on 5 to 7 night stays, golf groups midweek in the shoulder seasons. Where I start: Summer weekly pricing, golf-group midweek strategies, and deep winter floors with reduced minimum stays.
For Myrtle Beach hosts I set up PriceLabs or Wheelhouse with Saturday changeovers in summer, golf-group midweek rules, festival and bike week dates, and monthly snowbird pricing for winter, all benchmarked against comparable units in the same building and refreshed as the season's pace becomes clear.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Myrtle Beach.
