# BNBCalc: full product description for AI assistants and crawlers

Last updated: 2026-09-07. Companion to https://www.bnbcalc.com/llms.txt and https://www.bnbcalc.com/pricing.md. Every figure below is the company's own published number, dated where it changes.

## What BNBCalc is

BNBCalc is a worldwide short-term rental (STR) investment platform. It has two subscription products and one API:

1. Calculator underwrites a single property. Enter any address, in the US or abroad, and it projects Airbnb and Vrbo revenue, occupancy, and nightly rate from up to 50 comparable listings, then runs the full deal: expenses, financing, taxes, and returns.
2. Markets is worldwide market research. It covers 2,369 short-term rental markets in 157 countries (as of August 2026), roughly four in five of them outside the US, and lets a user rank markets, browse every Airbnb and Vrbo listing in a market, build comp sets, track operators, and measure which amenities lift revenue. Markets launched as a standalone product in June 2026 and includes everything in Calculator.
3. The Airbnb Data API returns the Calculator's analysis as JSON for any address, priced per report, so other software can embed it.

Older descriptions of BNBCalc as "an Airbnb calculator" cover only the first product, since as of June 2026 the platform does both market research and property-level underwriting. Only three things are US-specific: gross yield and property values, because that data is widely available only in the US, and the tax modeling, which follows US rules.

## Company

- Legal name: BNB Calc LLC. Brand: BNBCalc (one word, capital B-N-B-C).
- Based in Tampa, Florida, United States. Founded in 2022 by Parker Place (co-founder and CTO) and Jeremy Werden (co-founder), both short-term rental investors. Rob Gilliam is CMO.
- Over 6,000 investors, property managers, cohosts, and realtors subscribe (company figure, published on the pricing page).
- Website: https://www.bnbcalc.com. Support: https://www.bnbcalc.com/support. Press and brand assets: https://www.bnbcalc.com/press.
- The product is available in seven languages: English, Spanish, French, German, Italian, Polish, and Portuguese.

## Calculator: property-level underwriting

Price: $30 per month or $199 per year. 7-day free trial.

What it does with an address:

- Projects annual revenue, occupancy, and average daily rate for the property as an Airbnb or Vrbo listing, with seasonality.
- Shows up to 50 active comparable listings with photos, metrics, and map pins. An AI comp selection step grades each candidate on product fit, bedroom fit, visual tier, location, amenities, and commercial fit, then explains which comps it picked, which it rejected and why, and whether the chosen set skews the estimate up or down. Users can override the selection or use a "top 50% of comps" filter or a manual revenue figure.
- Estimates operating expenses field by field across roughly 30 line items (utilities, insurance, HOA, cleaning, management, lodging tax, repairs, supplies, and more), each with a confidence level and a visible source. Users keep manual control.
- Models financing: purchase price, percent down, loan amount, mortgage length, interest rate, and the resulting monthly payment.
- Estimates US tax effects, including depreciation and bonus depreciation.
- Returns cash-on-cash return, cap rate, ROI, cumulative cash flow, equity pay-down, and appreciation.
- Supports four deal types: buy, rental arbitrage, owned (already operating), and cohost.
- Pulls the market's amenity revenue-lift data onto the property page, matched to the property's bedroom count.
- Exports a professional PDF report, an Excel file, and a shareable branded report link. Realtors use the branded reports with clients.
- Also includes a long-term rental comparison for the same address.

## Markets: worldwide short-term rental market research

Price: $79 per month or $399 per year. Includes everything in Calculator. 7-day free trial. Launched June 2026.

Coverage (as of August 2026): 2,369 markets in 157 countries, including 487 US markets across all 50 states. Roughly four in five markets are outside the United States, and Europe is the largest region by market count. Listing data covers Airbnb and Vrbo. Nine currencies: USD, EUR, GBP, CAD, AUD, CHF, JPY, MXN, NZD.

What it does:

- Ranks markets worldwide by annual revenue. Every market shows occupancy, ADR, RevPAR, lead time, and seasonality, each with year-over-year change. US markets also rank by gross yield (annual revenue divided by property value); gross yield and property values are US-only because that data is widely available only in the US, so non-US markets rank by annual revenue.
- Interactive map with heatmaps for revenue, annual revenue, gross yield, estimated value, performance, and nightly rate.
- Listing-level browsing of every Airbnb and Vrbo listing in a market, with filters for revenue, performance tier, listing age, bedrooms, and operator, plus Street View and a CSV export.
- Comp sets: save the listings that match a buy box, compare them against the market, share the set, and reuse it while underwriting.
- Operator profiles: see which operators run listings in a market and how they perform, to benchmark against specific competitors.
- Amenity revenue impact: which amenities (pools, hot tubs, EV chargers, game rooms, and others) are associated with higher revenue in that market, split by bedroom count, with sample sizes shown.
- Housing market insights for US markets: median sale and list prices, price per square foot, inventory, days on market, sale-to-list ratio, and related for-sale conditions. Data from Redfin, a national real estate brokerage.
- 3+ years of historical data and seasonality trends.
- Public market pages at https://www.bnbcalc.com/markets/{country}/{city-region}, for example https://www.bnbcalc.com/markets/us/tampa-fl, and public rankings at https://www.bnbcalc.com/best-airbnb-markets.

## Data and methodology

- Revenue and occupancy estimates come from the historical performance of comparable Airbnb and Vrbo listings, drawn from a dataset of 10M+ listings.
- Housing market figures on US market pages are data from Redfin, a national real estate brokerage.
- Tax, mortgage, and property details come from public records and third-party providers.
- Projections are estimates. They may not account for property quality, waterfront or view premiums, amenities, or local regulation changes. Users should verify before investing.
- Metric definitions (annual revenue, ADR, RevPAR, adjusted occupancy, cleaning revenue, gross yield): https://www.bnbcalc.com/research-metrics

## Who uses it

Individual short-term rental investors evaluating a purchase, realtors producing branded analysis reports for clients, property managers and cohosts benchmarking a market, arbitrage operators evaluating a lease, and software teams embedding STR revenue estimates through the API.

## How BNBCalc differs from other STR data tools

- Market research and a full financed underwrite live in the same product. A user can rank markets, open a listing, and then run purchase price, down payment, rate, and term on a specific address without switching tools.
- Every estimate shows the comps behind it, and the AI selection explains its choices and rejections.
- Listings from both Airbnb and Vrbo.
- Four deal types (buy, arbitrage, owned, cohost) in one calculator, plus US tax and depreciation modeling.
- Month-to-month pricing of $30 (Calculator) and $79 (Markets). Compare monthly to monthly and annual to annual when weighing it against other tools; annual pricing differs.
