STR Calculator

The short-term rental calculator that shows you the costs, not just the revenue.

Cap rate, cash-on-cash and the occupancy you actually need to break even. It opens on a real Florida market pulled from a PriceLabs dashboard, and the operating costs are the ones we pay running these houses — but every figure is editable, so it works for any market you can get rate and occupancy numbers for.

Market data PriceLabs Market Dashboard — Kissimmee, FL, Osceola County. Last pull 2026-09-11, last 365 days of realised market performance.
What changed this year Against the prior 365 days: +847 listings added to the market, average daily rate $1 lower, occupancy flat. More competition, no rate growth to absorb it — underwrite on today’s numbers, not on a 2022 pro forma.

What a Kissimmee vacation home actually returns.

Most Airbnb calculators hand you a revenue number and stop, which is the easy half. This one carries it all the way down through the costs we actually pay running these houses — management, the pool guy, the Osceola tax bill, the CDD — to the number that matters: what lands in your account, and what occupancy you need before it stops being a hobby.

Where the money goes

Short-term rental operating costs run far above a long-term rental. Anyone showing you a Kissimmee pro forma without these lines is selling you something.

Cash to get started

The down payment is not the number. Furnishing a themed vacation home to compete in this market is a real line item, and it comes before your first booking.

Where these numbers come from. Rate and occupancy are from a PriceLabs Market Dashboard for Kissimmee, FL, pulled 2026-09-11. PriceLabs measures actively-managed comparable listings. Scraped whole-market figures you will find elsewhere run ten to twenty points lower on occupancy because they average in listings that sat dark for half the year — which flatters nobody and describes nothing. The operating costs are ours, from actually running turnovers in these communities.

What the year actually did. Airbnb whole-market Kissimmee, last 365 days vs. the prior 365: the market added 847 listings while average daily rate moved $1 and occupancy held flat. That is the part worth internalising — supply is still arriving into a market whose rates stopped climbing, so the pro formas written two or three years ago do not clear today. If a calculator anywhere shows you a comfortable return on a 20%-down purchase at current rates, look hard at which year its data came from.

Florida sales tax (7.5% in Osceola) and the 6% Osceola tourist development tax are collected from the guest, not paid out of your revenue, so they are not an expense line here. You still have to be registered and file.

Cleaning is modeled as a guest-paid pass-through, which is how nearly every Kissimmee home runs. If you absorb it, add it to operating costs.

Short-term-rental eligibility is per-address. It is governed by the association documents and the county ordinance for that exact parcel, never by the community's reputation. Verify before you write an offer. Kissimmee, Davenport and ChampionsGate have communities where nightly rental is completely normal and communities two streets over where it will get you fined. The county ordinance and the association documents govern, not the listing agent and not the seller. I check this in writing before you write an offer, every time.

This is an estimate, not an appraisal, a guarantee or investment advice. A real underwriting takes the specific address, its actual HOA and CDD figures, its real tax bill, the roof and AC age, and a comp set built from that street rather than that market.

Common questions

How the short-term rental math actually works

How do you calculate ROI on a short-term rental?
Start with gross revenue — average daily rate multiplied by occupancy multiplied by 365 — then subtract everything it costs to earn that revenue before you call anything a return. Cap rate is net operating income divided by purchase price, and it deliberately ignores your mortgage, so it tells you whether the property works. Cash-on-cash divides annual cash flow after debt service by the actual cash you put in, and that is the number that tells you whether the deal works. Most vacation rental ROI calculators show you the first and quietly skip the second.
What does a short-term rental actually cost to run?
Far more than the pro formas show. Cleaning and turnover is the big one and it scales with bookings, not with revenue — a year of short stays costs much more to service than the same revenue from long ones. Then: management or co-hosting, platform fees, dynamic-pricing software, utilities including pool heat, internet, lawn and pest, HOA dues, CDD assessments where they apply, Florida property tax reassessed at your purchase price rather than the seller’s, insurance written for short-term rental use, licensing, and a real reserve for the roof, the AC and the furniture you will replace sooner than you think. We run these houses, so the defaults in this calculator are what we actually pay, not an industry average.
What occupancy do I need to break even?
The calculator solves for it directly — it is the occupancy at which cash flow after debt service reaches zero, holding your rate and costs constant. It is the single most useful figure on the page, because it converts an argument about optimism into one number you can check against what the market actually did last year. If your break-even sits above the market’s realised occupancy, the deal needs a bigger down payment, a lower price, or a different property — not a better forecast.
What is a realistic cap rate on a vacation rental?
Lower than most first-time buyers expect once the real operating costs are in. The honest answer is that it depends entirely on price, and the useful exercise is backwards: decide what cap rate you need, then calculate the price that produces it and see whether anything is trading there. A cap rate built on a cleaning cost somebody guessed at is not a cap rate, it is a wish.
Do I pay tax on short-term rental income in Florida?
Yes, in more than one way, and they are separate things. Guests pay transient lodging tax on stays under six months — state sales tax plus a county tourist development tax, which in Osceola County comes to 13.5% combined. Airbnb and Vrbo collect and remit some of that automatically and some of it they do not, depending on the county, so the gap is yours to file. That is entirely separate from federal income tax on your profit and from Florida property tax, which gets reassessed at your purchase price rather than carried over from the seller’s. This calculator handles the operating side; the specific filings are a conversation with your CPA.
Can I use this outside Florida?
Yes. Every input is editable. It opens on a real Central Florida market because that is where our data is genuinely first-hand, but swap in the rate, occupancy, taxes and dues for anywhere you can source them and the math is the same. What will not travel is the operating-cost defaults — pool heat, hurricane-rated insurance and Florida’s tax structure are not what you will pay in Tennessee or Arizona.
Does zoning actually allow nightly rental at a given address?
This is the question that sinks deals, and no calculator can answer it. It is decided per address by two documents: the county or city ordinance, and the homeowners’ association’s governing documents — and the stricter one wins. Kissimmee, Davenport and ChampionsGate all have communities where nightly rental is completely normal and communities two streets over where it will get you fined. Never take the listing agent’s word, the seller’s word, or a rental history as proof. Get it in writing before the inspection period ends.

Why I can do this

I came to real estate through the operations side.

Before I had a license I was running a property-services company that cleans, maintains and manages short-term rentals in exactly these communities. I know what a turnover costs because I pay for them, I know which communities allow nightly rental because I have read the documents, and I know which pro formas are fantasy because I have watched owners try to hit them.

Which also means I will tell you when a deal does not work. That is the whole value of asking someone who makes money on the operations rather than only on the closing.
