About the Project
About crecalculators.com
crecalculators.com is a free set of commercial real estate calculators, built and maintained by Peter, an independent developer.
Why I Built This Site
I built this site because checking a deal shouldn't require a spreadsheet or a paid tool.
Every calculator runs entirely in your browser — no account, no sign-up, and no data sent to a server. Formulas are shown on the page, worked examples use real numbers, and the methodology is documented on the Methodology page.
How the Content Is Checked
- Calculation logic: Calculation logic is verified against worked examples before publication;
- Threshold ranges: Threshold ranges (for example, typical lender DSCR minimums) are labeled as typical, not guarantees;
- Sources linked: Sources are linked in the guides;
- Review dates: Pages carry a last-reviewed date.
Calculation Tool Disclaimer
This site is a calculation tool, not a brokerage, lender, or advisory service. It doesn't buy, sell, or finance properties, and nothing here is tax, legal, or investment advice.
