Airbnb Calculator

This Airbnb calculator does one thing properly: it compares what a property earns as a short term rental against what the same property earns rented long term, after every cost that short term hosting actually carries. You enter the average nightly rate, occupancy, average length of stay, the cleaning fee you charge and the cleaning cost you pay, platform fee percentage, supplies, utilities, internet, insurance and management. Then you enter the long term rent and long term expenses for the same property. It returns gross short term revenue, total short term costs, net income on both sides, the difference between them, and the break even occupancy where short term stops winning.

The honest limitation comes first: I cannot give you market nightly rates or occupancy data. That information is paid and proprietary, and any free tool that hands you a confident occupancy figure is either guessing or selling something. You supply those two inputs yourself, taken from real comparable listings in your area. Everything runs in your browser with nothing uploaded, and all of it is arithmetic on your assumptions, not tax or financial advice.

How to use

1. Open a few comparable listings nearby, similar size and amenities, and note their nightly rates and how full their calendars look.
2. Enter your average nightly rate and the occupancy percentage you believe you can hold across a full year, low season included.
3. Enter the average length of stay, which sets how many turnovers you will have and therefore how many cleans you pay for.
4. Enter the cleaning fee you charge guests and the cleaning cost you actually pay, since these are rarely the same number.
5. Fill in the running costs: platform fee percentage, supplies, utilities, internet, insurance and management if someone else runs it.
6. Enter the long term monthly rent and long term expenses for the same property so the comparison has something real on the other side.
7. Read the net income for each strategy, the difference, and the break even occupancy that separates them.

Why use our airbnb calculator?

Deriving turnovers from length of stay is the detail that changes results. Twenty booked nights as ten two night stays is a completely different cost structure from two ten night stays, because every turnover means a clean, a restock and a gap. The number I got wrong first was exactly this: I assumed cleaning was covered by the cleaning fee, discovered my cleaner charged more than guests would tolerate paying, and quietly ate the difference on every booking for a year.

The long term comparison sits alongside rather than in a separate tool because the real question is never whether short term makes money. It usually does. The question is whether it makes enough more than the boring alternative to justify the messages, the reviews, the linens and the risk. If the gap is two hundred dollars a month, that is a job, not an investment edge.

Break even occupancy is the number I would put on a sticky note. It tells you how full you must stay before short term merely matches long term, and it converts a vague optimism about bookings into a threshold you can measure against every month. If your break even is 62 percent and your comparable listings look half empty in February, you have your answer.

Regulation is the biggest risk in any short term rental model, and no calculator can price it. Permit caps, primary residence requirements, minimum stay ordinances and HOA rules can end a short term business in a single council vote, and they change faster than any spreadsheet. Check your city and county rules before you count on a single night of revenue.

What I refuse to add is a market data lookup, because I would have to invent the numbers or charge you for them. Everything you type stays in your browser, there is no account, and nothing is uploaded to me or anyone else.

Who is this tool for?

Deciding what to do with a property you already own is the most common visit. A tenant is leaving, you have heard what neighbors claim to earn nightly, and you want the comparison done with your real costs rather than someone's screenshot.

Underwriting a purchase that only works as a short term rental is riskier, and the tool is built to show you why. Run it once at your hoped for occupancy and once at long term rent alone. If the deal collapses under the long term scenario, you are betting the whole purchase on local regulation staying friendly. The rental property calculator gives you that long term view in full, with financing and reserves included.

Stress testing an existing listing is the quiet win. Put in your actual trailing twelve months, then rerun with occupancy down ten points, or with the cleaner charging twenty dollars more. Knowing which lever hurts most tells you where to focus before the market decides for you.

Triaging listings quickly before any of this is what the rental deal screener is for, and once a property clears both screens, the cash on cash return calculator puts the return in terms of the cash you personally put in.
