How it works
How the BNBCalc Airbnb calculator works
Enter an address or Zillow link
Type any address, in the US or abroad, or paste a Zillow link. Add the bedrooms, bathrooms and guests so the comps match your property.
Get up to 50 graded comps
BNBCalc pulls up to 50 comparable Airbnb and Vrbo listings nearby. An AI step grades each one for fit, shows why it kept or rejected it, and flags when the set skews the estimate up or down. You can change the set yourself.
Review revenue and expenses
Those comps drive the projected revenue, occupancy and nightly rate. BNBCalc also estimates operating expenses line by line, and you decide which estimates to keep.
See the full return
Add the purchase price and financing to see cash flow, cap rate, cash-on-cash return and estimated first-year tax savings, then share the report with a link.
Tax savings
Maximize your rental property tax deductions
The 2025 tax bill restores 100% bonus depreciation for short-term rentals — one of the largest write-offs in real estate. BNBCalc estimates your first-year deductions so you see the after-tax return, not just the rent.

What our users say
“Most under-rated tool. The tax savings feature alone makes my subscription worth it.”
John Bianchi
Head of Data, STR Search / Techvestor
“Love using BNBCalc especially when it comes to drawing up quick projections on the fly of a potential clients property to see if they're hitting the projected numbers. BNBCalc helps me close new clients.”
Jackson Sterns
Property Manager, Tampa Bay Stays LLC
“This tool is amazing! Used it to find my first short term rental. It was very helpful in better understanding the market. Definitely a must-have tool if you are considering purchasing an STR.”
Jake Kempton
“I have to admit that this is one of the most useful tools I’ve used in helping me decide on the short term rental property. It breaks down the projections for the occupancy rate and by percentage on multiple studies!! Also, the seasonality by month. And the potential tax savings I’ll get.”
Elaine Young
“I use this tool to evaluate all of my short-term rental opportunities. It provides a consistent and intuitive template, useful comparisons, and a flexible interface.”
Peter Aylaian
“I really liked that I could do a quick analysis on the website instead of setting up my spreadsheet. Great tool that saves a lot of time when evaluating properties.”
Afrina M
“The BNBCalc was excellent, and I liked how I could compare it to nearby rentals. I am looking to build on a vacant lot (that I already own) soon, so the BNBCalc helped ensure my decision to build a STR was a good one.”
Lynd Utke
“Very easy to use and necessary to understand a local market or an area where to invest with new apartments.”

Airbnb calculator FAQ
Is the BNBCalc Airbnb calculator free?
You can run two property analyses free without a plan. After that, the Calculator is $30 per month or $199 per year, and it starts with a 7-day free trial with full access, so you won't be charged if you cancel before the trial ends.
How does the Airbnb calculator estimate revenue?
It pulls up to 50 comparable short-term rentals near the address and projects revenue, occupancy and nightly rate from how those listings actually performed. An AI step grades each comp for fit, explains which ones it kept and why, and flags when the set skews the estimate up or down.
How accurate is the revenue estimate?
Accuracy depends on how closely the comps match your property, and the more active comparable listings there are near an address, the more reliable the projection. Before you rely on the number, check the AI's reasons and narrow the set to listings like yours.
Does the calculator work outside the US?
Yes. The calculator takes any address, in the US or abroad. Tax and depreciation estimates follow US rules.
Does it include Vrbo as well as Airbnb?
Yes. Revenue projections and comparable listings draw on both Airbnb and Vrbo.
Can I model a mortgage and cash flow?
Yes. Enter the purchase price, down payment, interest rate and loan term, and the report shows cash flow, cap rate and cash-on-cash return with that financing, alongside setup costs and operating expenses.
Does it estimate bonus depreciation and tax savings?
Yes. It estimates first-year deductions, including a bonus depreciation schedule and a cost-segregation savings estimate, and compares standard with accelerated depreciation so you see the after-tax return. Tax modeling follows US rules.
