Question 1

What does BNBCalc do?

Accepted Answer

BNBCalc predicts what a property will earn, and it ranks the markets to buy in, worldwide. The Calculator predicts Airbnb, Vrbo, and long-term rental revenue for any property: enter an address, in the US or abroad, and it returns revenue projections, average daily rate, occupancy, up to 50 comparable listings, a financial summary with expenses and financing, and estimated tax deductions including depreciation. Markets, launched in June 2026, ranks and explores 2,300+ short-term rental markets in 157 countries, with every listing on a map, comp sets, operator tracking, and amenity revenue impact. A REST API returns the property analysis for developers.

Question 2

What is BNBCalc Markets?

Accepted Answer

BNBCalc Markets is BNBCalc's worldwide market research product, launched in June 2026. It covers 2,300+ short-term rental markets in 157 countries, roughly four in five of them outside the US, and lets you rank markets by annual revenue, see every Airbnb and Vrbo listing in a market on a map, build comp sets, track operators, and measure which amenities lift revenue. US markets also rank by gross yield, a metric that needs property-value data widely available only in the US. It costs $79 per month or $399 per year and includes the Calculator.

Question 3

How accurate is BNBCalc?

Accepted Answer

BNBCalc bases its revenue projections on up to 50 comparable short-term rentals already operating near the subject property, using Airbnb, Vrbo, and Zillow data across more than 3 million analyzed properties. An AI step grades each comp for fit and flags whether the chosen set skews the estimate up or down. The more active comparable listings near an address, the more accurate the projection.

Question 4

How much does BNBCalc cost?

Accepted Answer

BNBCalc is free for the first 7 days with full access. After the trial, the Calculator is $30 per month or $199 per year, and Markets is $79 per month or $399 per year with the Calculator included. Cancel anytime, and there's a full refund within 14 days of any charge. Free members can still run two property analyses, and the free tools (DSCR calculator, Section 8 rent map, and STR tax calculator) stay free.

Question 5

How does BNBCalc compare to AirDNA, Rabbu, AllTheRooms, and Mashvisor?

Accepted Answer

BNBCalc combines Airbnb and Vrbo revenue projections, long-term rental comps from Zillow, Section 8 Fair Market Rent data, a built-in depreciation tax calculator, and worldwide market research in one platform, from $30 per month. Where many tools focus on one dataset or a single metric, BNBCalc runs the whole deal, from choosing the market to financing the specific address, in one shareable report.

Question 6

Does BNBCalc work outside the United States?

Accepted Answer

Yes. BNBCalc is a worldwide tool. Markets covers 2,300+ short-term rental markets in 157 countries, roughly four in five of them outside the United States, and the Calculator takes any address. Gross yield and property values are US-only, because that data is widely available only in the US, so markets elsewhere rank by annual revenue. Tax and depreciation modeling follows US rules.

Question 7

Who built BNBCalc?

Accepted Answer

BNBCalc was founded in 2022 by short-term rental investors Parker Place and Jeremy Werden, who built the calculator after finding existing tools too expensive or too inaccurate. Today it is maintained by a team of real estate investors, engineers, and data specialists in Tampa, Florida.

Question 8

Does BNBCalc have an API?

Accepted Answer

Yes. The BNBCalc Airbnb Data API returns projected revenue, occupancy, ADR, comparable listings, cash flow, and investment metrics for any address, plus a hosted report link. It costs $0 per month plus $0.20 per successfully created report, with self-serve API keys and no contract. Documentation is at bnbcalc.com/rest-api.

Question 9

What is BNBCalc?

Accepted Answer

BNBCalc is a worldwide short-term rental investment platform with two products. The Calculator projects revenue, cash flow, ROI, and tax savings for any address, in the US or abroad, using up to 50 comparable Airbnb and Vrbo listings. Markets ranks and explores 2,300+ short-term rental markets in 157 countries. A REST API returns the property analysis for developers, and two property analyses are free.

Question 10

How does the Airbnb calculator work?

Accepted Answer

Enter any property address, or paste a Zillow link, and the calculator pulls up to 50 comparable short-term rentals nearby. BNBCalc grades each comp for fit, then shows you which ones it kept and why, and the real performance data behind them (revenue, occupancy, and nightly rates) drives the projection for your property.

Question 11

Does BNBCalc calculate tax benefits?

Accepted Answer

Yes. The tax calculator estimates depreciation, including bonus depreciation, and the other short-term rental deductions that can offset rental income, so you see the after-tax return and not only the rent. Tax modeling follows US rules.

Question 12

What countries does BNBCalc cover?

Accepted Answer

Yes, worldwide. BNBCalc Markets covers 2,300+ short-term rental markets in 157 countries, roughly four in five of them outside the US, and Europe is the largest region by market count. The Calculator takes any address, in the US or abroad. Two things are US-only: gross yield and property values, because that data is widely available only in the US, and the tax modeling, which follows US rules.

Question 13

Where does BNBCalc get its Airbnb data?

Accepted Answer

Revenue, occupancy, and nightly-rate figures come from the historical performance of comparable Airbnb and Vrbo listings, drawn from a dataset of 10M+ listings with 3+ years of history. Tax, mortgage, and property details come from public records and third-party providers, and US housing market figures are data from Redfin, a national real estate brokerage.

Question 14

How accurate are your Airbnb revenue projections?

Accepted Answer

Projections are based on actual performance data from up to 50 comparable properties. Accuracy depends on how closely the comps match your property, so refine the set to listings like yours, or let the AI comp selection do it and check its reasons.

Question 15

How many STR markets does BNBCalc cover?

Accepted Answer

BNBCalc Markets covers 2,300+ short-term rental markets in 157 countries, worldwide. Markets rank by annual revenue, and every market shows occupancy, ADR, RevPAR, and seasonality with the Airbnb and Vrbo listings behind the numbers. US markets also rank by gross yield, a metric that needs property-value data widely available only in the US.

Question 16

Is there a free trial?

Accepted Answer

Yes. Both plans start with a 7-day free trial with full access, and you won't be charged if you cancel before it ends. Free members can also run two property analyses without a subscription.

Question 17

What is your refund policy?

Accepted Answer

We offer 100% refunds within 14 days of any charge. Contact hello@bnbcalc.com or visit bnbcalc.com/support and we'll process your refund within one business day.

Question 18

How does BNBCalc compare to AirDNA?

Accepted Answer

Both tools sell short-term rental market data. BNBCalc pairs that research with a full property underwrite: enter an address and you get 50 comparable listings, expenses, financing, taxes, and returns in the same tool. Markets is $79 per month or $399 per year and includes the Calculator; the Calculator alone is $30 per month or $199 per year. The full comparison is at bnbcalc.com/bnbcalc-vs-airdna.

Question 19

How does BNBCalc compare to Mashvisor?

Accepted Answer

BNBCalc shows up to 50 live Airbnb and Vrbo comparables for every property, models four deal types (buy, rental arbitrage, owned, and cohost), and adds worldwide market research through Markets. Calculator plans start at $30 per month.

Question 20

Is BNBCalc better than spreadsheets?

Accepted Answer

BNBCalc automates what takes hours by hand: pulling 50 comparables, projecting revenue from real Airbnb and Vrbo data, estimating expenses line by line, and producing a professional report in seconds. Most investors find it pays for itself after one analysis.
