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 Piran: Piran's Venetian old town; Portorož beaches and casinos; Izola and Koper; Day trips from Ljubljana and Trieste. Guests I price for: Slovenian, Austrian and Italian couples and families on 2 to 5 night stays. Where I start: Summer premiums, small-apartment pricing and tourist tax.
I set the pricing tool so summer weekends and holiday dates in Slovenia, Austria and Italy are priced higher, minimum stays change with the season, and winter rates stay attractive for short breaks. I also check that the tourist tax shows correctly on Airbnb and Booking.com.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Piran.
