Cap rate, NOI, DSCR and rental calculators

Pro and API (coming soon)

Last updated 2026-10-15

Every calculator on Rental Metrics Desk is free and stays free. We are considering a paid option for people who run the numbers on many properties or leases — landlords, small investors, property managers, brokers and tenants comparing offers. It does not exist yet. If it sounds useful, leave your email below and we will write to you once, when it opens.

What stays free

  • Every calculator on the site, with the full result and the working shown under it.
  • Print or save a result as a one-page sheet, and share it through a link.

What Pro would add

  • Saved properties: keep the inputs for each property or lease under a name and open them again later, instead of keeping a list of links.
  • PDF reports: a formatted report of a calculation, with your own name or logo on it, to hand to a partner, lender or client.

We will only build these if enough people ask for them, and we will not take payment until they work.
