Rental Property Cash Flow Calculator

Estimate NOI, cap rate, monthly cash flow, and DSCR-style coverage.

Understanding Your Results

Net Operating Income (NOI) is the property’s rental income minus operating expenses (taxes, insurance, HOA, maintenance, and management), before accounting for the mortgage payment. Cap rate is NOI divided by the property’s price or value, and is commonly used to compare properties independent of financing. DSCR-style coverage compares the property’s income to its total debt service (the mortgage payment) — a ratio above 1.0 means the property’s rent covers the loan payment.

Cash Flow Calculator FAQs

What’s the difference between cash flow and NOI?

NOI is calculated before the mortgage payment; cash flow is what’s left after the mortgage payment is subtracted from NOI. A property can have strong NOI but negative cash flow if it’s financed aggressively.

What cap rate is considered good?

It depends heavily on the market and property type — cap rates vary widely between markets. Comparing a property’s cap rate to similar properties in the same market is more useful than comparing it to a single national benchmark.

Does this calculator affect my DSCR loan qualification?

This tool provides an estimate to help you evaluate a deal. Actual DSCR loan qualification depends on the lender’s specific underwriting guidelines, the property appraisal, and documentation review. See our DSCR loan requirements for more detail.
