Short-Term Rental Investment Formula

This calculator projects annual revenue from nightly bookings, subtracts platform fees, management fees, and operating expenses to find NOI, then layers in financing to estimate cash flow and cash-on-cash return — giving investors a cap-rate-based view of short-term rental profitability.

Annual Booked Nights = 365 × Occupancy Rate %
Gross Rental Revenue = Average Nightly Rate × Annual Booked Nights
Platform Fees = Gross Rental Revenue × Platform Fee %
Management Fees = Gross Rental Revenue × Management Fee %
Operating Expenses (Annual) = Monthly Operating Expenses × 12 + Annual Property Tax + Annual Insurance
NOI = Gross Rental Revenue − Platform Fees − Management Fees − Operating Expenses
Cap Rate (%) = (NOI ÷ Purchase Price) × 100
Annual Cash Flow = NOI − Annual Debt Service
Total Cash Invested = Down Payment + Closing Costs + Furnishing/Setup Cost
Cash-on-Cash Return (%) = (Annual Cash Flow ÷ Total Cash Invested) × 100

Unlike long-term rentals, short-term rental revenue depends heavily on occupancy rate and average nightly rate, both of which fluctuate seasonally and by market. Platform fees (e.g., booking site commissions) and professional management fees (often 15-30% of revenue for full-service STR management) are typically higher than for long-term rentals, and furnishing/setup costs represent an additional upfront investment beyond the down payment and closing costs.

Real-World Scenario Example

"An investor buys a $400,000 vacation property with 25% down at 7% interest over 30 years, renting it at an average of $250/night with 55% occupancy, an 18% management fee, and $1,200/month in operating expenses plus $15,000 in furnishing."

Result

With about $50,200 in projected annual revenue at 55% occupancy, the property generates roughly $19,800 in NOI for a cap rate near 4.9%, with positive monthly cash flow after debt service producing a solid cash-on-cash return on the total cash invested.
