What free tools and calculators does BNBCalc offer?

Last reviewed Oct 22, 2026 by Jeremy Werden

Short answer

BNBCalc's free tools need no plan: an Airbnb calculator and a rental arbitrage calculator for any address, Airbnb tax and income tax calculators, amortization, DSCR and sell-or-refinance calculators, Section 8 rent tools, a material participation hours tracker and the Best Airbnb Markets rankings. The Airbnb calculators open a full BNBCalc analysis, which counts toward your free analyses.

Which free Airbnb calculators does BNBCalc have?

Two of BNBCalc's free pages start a full property analysis from an address:

  • the Airbnb calculator, which estimates what a home would earn as a short-term rental from the comparable listings near it, then works through expenses, financing and returns;
  • the Airbnb arbitrage calculator, for a home you'd rent from a landlord and list yourself. Make sure to pick Rent as the analysis type, so BNBCalc subtracts your rent instead of a mortgage.

Because both run a real analysis, each one counts toward your free analyses. You can run two in each browser without an account, although an upgrade window covers those reports and hides the comps, while a new free account includes 2.

Which free tax tools does BNBCalc have?

  • The Airbnb tax calculator compares the year-one loss and tax offset of a short-term rental with a long-term one, from a handful of inputs and no address.
  • The income tax calculator works out federal, FICA and state tax on your income, and what's left as take-home pay.

Both say they aren't tax advice, and they're best used to compare options before you talk to your CPA.

Which free financing calculators does BNBCalc have?

  • The amortization calculator shows a loan's monthly payment and how each payment splits between interest and principal.
  • The DSCR mortgage calculator divides net operating income by your loan payments, the ratio DSCR loans are named after.
  • The sell or refinance calculator compares selling a rental with refinancing it. Make sure to enter what you still owe on the mortgage, since the cash-out figures depend on it.

What free market data does BNBCalc have?

The Best Airbnb Markets pages rank the markets in each US state and other countries, with each market's revenue, nightly rate and occupancy, and you don't need an account to open them.

Is there a free material participation tracker?

Yes. BNBCalc's Hours tracker logs the hours you spend on each short-term rental and checks them against three of the IRS material participation tests. It works on any free account, so create one before you start a log you'll keep.
