Airbnb Calculator: Estimate Short-Term Rental Revenue and ROI

What an Airbnb Calculator Estimates

An Airbnb calculator is built for short-term rental assumptions: average daily rate, occupancy, cleaning revenue, platform costs, turnover expenses, utilities, furnishing, and seasonal swings.

The goal is to separate gross booking revenue from actual owner cash flow. High nightly rates can hide high vacancy, cleaning, supplies, maintenance, and management costs.

Revenue Formula

Booked nights are driven by occupancy. A $180 nightly rate at 60% occupancy over a 30-day month means 18 booked nights and $3,240 in room revenue before fees and expenses.

Expenses to Include

• Cleaning cost and whether it is fully passed to guests.
• Platform fees, payment processing, lodging taxes, and local permits.
• Utilities, internet, supplies, linens, repairs, and replacement reserves.
• STR management fees if you will not handle guest communication and turnovers.
• Mortgage, property taxes, insurance, HOA fees, and furnishing costs.

Seasonality Matters

Short-term rentals rarely perform evenly every month. A beach, ski, college, or event-driven market may earn a large share of annual revenue in a few peak months.

Use conservative annual assumptions. If the property only works at peak-season occupancy all year, the deal is likely too fragile.

How to Use the Result

Compare short-term rental cash flow against a long-term rental fallback. If local rules change or occupancy drops, the property should still have a realistic plan.

Also test management. Self-management can improve returns but requires time. Professional management may reduce stress but can materially lower cash flow.
