Airbnb and Short-Term Rental Calculator
Model the revenue first, then confirm the address is even allowed to rent that way.
What This Calculator Does
Multiplies your average daily rate by occupancy to project annual revenue, then subtracts what a short-term rental actually costs to run — cleaning, platform fees, furnishings, utilities, management, lodging taxes — to show net income and how it compares with renting the same unit annually.
Who Is This For
Investors weighing short-term against annual rental income, owners of Miami condos who want to test the math before furnishing, and buyers who need to know whether a listing's advertised Airbnb income survives contact with the building's rules.
How It Works
Enter the average nightly rate and occupancy you expect, or start from market benchmarks and adjust. Add cleaning, management, and furnishing costs, then compare the net result against the long-term rent the same property would command.
Frequently Asked Questions
What occupancy and nightly rate should I assume?
Use the specific building and unit type wherever you can. As a market-level reference, AirDNA data for Miami in 2026 puts occupancy near 56% and the average daily rate near $277. Your own numbers will move with location, view, bedroom count, and how actively the listing is managed.
Is short-term renting legal at my address?
This is the question that decides the deal, and it is answered locally. Municipalities across Miami-Dade regulate short-term rentals differently — some by zoning district, some by registration requirement, some by outright prohibition in residential areas. Confirm the rule for the exact address before you underwrite anything.
What about condo rules?
A building's declaration and rules can set a minimum lease term, as many South Florida associations do, and that term overrides your business plan regardless of what the city permits. Read the condo documents during your inspection period, not after closing.
What taxes apply to short-term stays?
Short stays are taxable lodging in Florida: state sales tax plus the county tourist development levy, on top of any local registration or licensing requirement. Platforms collect some of these automatically and not others, so confirm which ones remain your responsibility.
Why is my net so much lower than gross revenue?
Because a short-term rental is an operating business. Cleaning between stays, platform commission, utilities and internet, furnishing and replacement, higher insurance, and management all come out before you compare with a long-term lease. Vacancy is real too — occupancy well under 100% is normal, not a failure.
Is short-term always better than an annual lease?
No. It wins when the nightly premium clearly beats the operating drag and the property is legally permitted to do it. When the building caps lease terms or the season is thin, an annual tenant produces more reliable income with far less work.
