How an Airbnb calculator actually works

Short-term rentals look incredible on a spreadsheet and grueling in real life. The math only works when every cost is honest: cleaning per turnover, supplies, platform fees, dynamic-pricing tools, higher utility bills, and the management percentage you'll pay once the novelty wears off.

The revenue formula

Monthly revenue = ADR × Occupancy × 30. A property running $220 ADR at 62% occupancy produces ~$4,100/mo gross. From that, subtract platform fees (Airbnb takes 3% from the host; host-only fees of 14–16% are also common on certain markets), cleaning labor, supplies, utilities, internet, dynamic pricing tools, and management.

Benchmarks worth hitting

  • RevPAR ≥ 1.5–2× long-term rent. If a $2,200/mo LTR can only produce $2,600 RevPAR, the operational lift rarely justifies it.
  • Occupancy 55–70%. Below 50% usually means oversupply or weak ADR positioning.
  • Cash-on-cash 12–20%. Higher than LTR because furniture cost + operational risk demand a premium.

Where STR projections blow up

  • Top-of-market ADR assumptions. Use AirDNA/Rabbu medians, not the cherry-picked listing.
  • Ignoring shoulder months. A summer-beach market that books 90% in July and 20% in February still has to cover the mortgage in February.
  • Self-cleaning at $0. Even a couple cleaning fees per month is real labor. Model it.
  • Regulatory blindness. Many cities cap or ban non-owner-occupied STRs. Verify before you close.

Glossary

  • ADR: Average Daily Rate. The nightly rate guests pay.
  • Occupancy: Percent of bookable nights actually booked.
  • RevPAR: Revenue Per Available Rental. ADR × occupancy.
  • Turnover: A guest checkout + cleaning + reset. Drives cleaning cost.
  • Dynamic pricing: Tools like PriceLabs, Wheelhouse that adjust ADR daily based on demand.
