Questions answered
STR calculator questions
What does an STR calculator estimate?
Three numbers drive every short-term rental decision: annual revenue, average daily rate (ADR), and occupancy. This calculator estimates all three for a specific address from comparable listings nearby, then hands off to the pro forma builder for expenses, financing, and returns.
How is this different from AirDNA’s Rentalizer?
Same category of tool, different data source — and free. Whichever estimator you use, treat address-level projections as a starting hypothesis: our Rentalizer accuracy breakdown explains why we underwrite year one at 60–75% of any projection.
What should I do with the estimate?
Screen with it, then underwrite: take the revenue number into the pro forma builder, model the full cost stack and financing, and check local regulations before an offer.
Under the hood
Where the numbers come from
STR calculator estimates are built from comparable short-term rentals near the exact address you enter — real nightly rates and booked nights, not metro-wide averages. Treat any instant estimate as a ceiling: established comps outperform launch-year listings, so model year one at 60–75% of the projection (our AirDNA Rentalizer analysis explains why). Then turn the revenue number into cash flow with the free pro forma builder, guided by the Airbnb pro forma template checklist.
