Airbnb & Short-Term Rental Calculator
Project STR revenue, platform fees, lodging tax, NOI, annual cash flow, DSCR, cap rate, cash-on-cash return, and break-even occupancy.
Preliminary screening tool only. STR performance and legality depend on local rules, seasonality, platform policies, tax collection, lender terms, and property execution. Verify city, county, zoning, HOA, permit, lodging-tax, insurance, and lending assumptions before committing capital. This is not legal, tax, investment, or lending advice.
Example: Texas STR at $180 ADR and 55% occupancy
A $350,000 Texas STR with $180 ADR, 55% occupancy, 365 available nights, 3-night average stays, Airbnb split pricing, 12% pass-through lodging tax, 15% management, and $1,900 monthly debt service shows the core underwriting path: revenue first, then host fees, taxes, OpEx, NOI, cash flow, and break-even occupancy.
How the STR calculator works
The calculator starts with ADR, occupancy, available nights, average stay length, and cleaning fee assumptions. It converts those inputs into booked nights, estimated stays, nightly revenue, cleaning-fee income, and gross booking revenue.
Platform fees, cleaning costs, management, maintenance reserves, fixed operating expenses, and owner-absorbed lodging taxes reduce NOI. Annual cash flow then subtracts debt service and the capex reserve. Pass-through lodging taxes and guest platform fees are shown for pricing visibility but excluded from host NOI.
Break-even occupancy is solved from the current ADR, expense, fee, tax, reserve, and debt assumptions. The sensitivity panel shows conservative, stress, and upside cases so the base projection is not the only number on the screen.
STR projection formulas
- Booked Nights = Available Nights x Occupancy
- Stays = Booked Nights / Average Stay Length
- Nightly Revenue = ADR x Booked Nights
- Gross Booking Revenue = Nightly Revenue + Cleaning Fee Income + Other Guest Fees
- NOI = Gross Booking Revenue - Operating Expenses Before Capex
- Annual Cash Flow = NOI - Debt Service - Capex Reserve
Analyze STR deals by state
Pick a state to seed property-tax, insurance, median-home-value, and local-diligence context. Local STR rules still need city and county verification.
Frequently Asked Questions
What is ADR in a short-term rental calculator?
ADR means Average Daily Rate. In this calculator, ADR is nightly rent only. It excludes cleaning fees, lodging taxes, and platform guest fees so revenue and tax math stay separated.
Should lodging tax count as STR revenue?
If lodging tax is passed through to the guest and remitted to tax authorities, it should not count as host revenue or NOI. If the owner absorbs the tax, the calculator treats it as an operating expense.
Does this calculator tell me if an Airbnb is legal?
No. State-level defaults cannot verify local STR legality. City, county, zoning, HOA, primary-residence, permit-cap, tax-registration, and enforcement rules must be checked locally.
