Short-term rentals can produce more gross revenue than a traditional lease in some markets, but they also add operating, occupancy, regulatory, and management risk. This calculator makes the assumptions visible so you can compare scenarios with clearer numbers.

Revenue Drivers: Rate, Occupancy, and Seasonality

Revenue is driven by nightly rate, occupied nights, and cleaning-fee turnovers. All three are market- and property-specific. Use current comparable listings, local seasonality, and your actual operating plan to set a conservative low, mid, and peak case. Do not project peak-season performance across the full year. The calculator's seasonality matrix lets you model different monthly rates and occupancy instead of hiding that variation inside one annual average.

Operating Costs That Separate STR from LTR

Short-term rentals can have a different cost structure from long-term rentals: utilities, insurance, cleaning, supplies, management, platform fees, lodging taxes, and replacement reserves may all be material. Enter each monthly cost and percentage separately. Cleaning fees are shown as booking revenue and an equal cleaning expense, so they are treated as pass-through unless your fee and actual cleaner cost differ. The calculator does not estimate taxes, permits, depreciation, or insurance pricing.

Cash Flow vs. Appreciation: Two Investment Theses

Cash flow and appreciation are different return sources. The calculator reports monthly and annual cash flow, cap rate, cash-on-cash return, DSCR, and a five-year projection with user-supplied growth rates. The projection also assumes a 6% selling-cost deduction at liquidation; that is a planning assumption, not a quote. Review the cash-flow case separately from appreciation and test what happens when occupancy, rates, expenses, or financing move against you.

Regulatory Risk and Insurance Considerations

Local rules and insurance can determine whether an STR is viable before revenue matters. Check the city or county permit process, taxes, operating limits, HOA or condo documents, lease restrictions, and current enforcement before buying. Ask an insurer whether the policy covers short-term rental activity. Airbnb describes AirCover as host protections, but its terms and exclusions apply and it does not replace a policy suited to your property and activity. None of those legal, insurance, or tax checks are performed by this calculator.
