STR Profit Diagnostic

Is your Airbnb
actually making money?

Market data tools tell you what similar listings earn. That's not your profit.
Host Profit OS uses your real numbers — your ADR, your costs, your taxes — and shows exactly what you keep after every fee, cleaning bill, and tax obligation. Find out in 30 seconds.

What hosts are saying

From hosts who ran the numbers

"I thought I was making $800/month profit. After running this I realized it was closer to $340 after cleaning, fees and tax. Complete eye-opener."

— Marcus T., 1-bed apartment host, Barcelona

"The break-even analysis alone was worth it. I was operating at 68% occupancy thinking I had buffer. Turns out I needed 61% just to break even — not much cushion."

— Sarah K., STR host, Lisbon

"Used it to analyze a second property before signing the lease. The numbers didn't work at current ADR. Saved me from a bad deal."

— James R., arbitrage operator, London

The Problem

The questions hosts
can't answer honestly

Every host thinks they know their numbers. Most don't. These are the questions Host Profit OS answers in 30 seconds.

"What's my actual margin after platform fees, cleaning, utilities and tax?"

Most hosts have no idea. They see revenue — not profit.

"If occupancy drops 10% next month, do I still break even?"

A slow month can quietly turn profit into a loss.

"Is my Airbnb healthy enough to justify a second property?"

Scaling a weak structure amplifies losses, not gains.

"What's my break-even occupancy — and how far am I from it?"

The most important number in short-term rentals. Almost nobody tracks it.

Things hosts ask us

Does it work for platforms other than Airbnb?

Yes. You enter your own platform fee percentage — so it works for Booking.com, VRBO, direct bookings, or any combination.

What about VAT, tourist tax and income tax?

All three are built in. You enter your occupancy/tourist tax rate, VAT rate, and income tax rate separately. The tool shows profit before and after every tax obligation side by side.

Is this bookkeeping software? Does it sync with my bank?

No. Host Profit OS is a planning and decision tool, not bookkeeping software. It doesn't sync with anything. You enter your numbers, it shows you what they mean. Use a bookkeeping tool separately for historical tracking.

I'm just starting — is this useful before I have real data?

Yes, this is where it's most valuable. Enter expected ADR, projected occupancy and estimated costs. The tool tells you whether the deal makes financial sense before you sign anything.

What's included in the $47 bundle exactly?

The interactive web calculator, the Excel spreadsheet with multi-property comparison, and the Host Profit Guide — a detailed PDF guide covering profit architecture, pricing strategy, stress testing and scaling criteria.

Can I use this on my phone?

The web calculator works on any browser including mobile. The spreadsheet works best on desktop Excel or Google Sheets.
