About NOICalculator.org

NOICalculator.org is a free calculator and a set of guides for investors who want to know what a rental property earns before the mortgage. It exists because most NOI calculators online ask for two numbers and return one. This one builds the full income statement, line by line, shows the expense ratio behind the result, and turns the NOI into a value at whatever cap rate your market trades at.

Part of a family of six calculators

NOICalculator.org is one of six free rental property calculators built by the same people on the same calculation engine. Each covers one metric in depth and links to the others where the metrics meet:

• DSCR Loan Calculator: does the rent cover the payment?
• Cash on Cash Return Calculator: yield on the cash you put in
• Cap Rate Calculator: noi, cap rate and value
• GRM Calculator: gross rent multiplier screen
• BRRRR Calculator: buy, rehab, rent, refinance

Independence

The site is not owned by a lender or broker and does not sell leads. If that ever changes, it will be disclosed on this page and on any page where it applies.

How the numbers are produced

Every figure on the site comes from one open calculation engine. The formulas, assumptions and their limits are documented on the methodology page. Where a page states typical expense ratios or market cap rates, those are ranges commonly observed, not a guarantee of what any property or market will do.

Not advice

The calculator and guides are educational. They are not investment, financial, legal or tax advice. Results depend on inputs and assumptions you control. Verify rents, taxes, insurance and expenses for the specific property before relying on any figure here.
