NOI is income minus operating expenses (before any mortgage). Replace the default percentages with your real numbers as you learn the property.

What is NOI?

NOI (Net Operating Income) is a property's annual income after deducting all operating expenses but before mortgage payments and income taxes. It's the foundation for calculating cap rate and DSCR.

Formula
NOI = Gross Rental Income − Vacancy Loss − Operating Expenses

How this calculator works

NOI (Net Operating Income) is the income left after operating expenses — before the mortgage. NOI is used for cap rate, DSCR, and value comparisons across deals.

What it includes
  • Gross income
  • Vacancy loss
  • Operating expenses (excl. mortgage)
  • NOI (monthly + annual)
How to use it
  1. Enter stabilized rent and any other monthly income.
  2. Add a vacancy assumption (conservative is better for screening).
  3. Enter operating expenses (property tax, insurance, HOA, utilities, maintenance/reserves).
  4. Use NOI to compare deals and to compute cap rate or DSCR.

FAQ

What’s the difference between NOI and cash flow?
NOI is before the mortgage. Cash flow is NOI minus the mortgage payment (and any other debt payments).
What should I include as operating expenses?
Include recurring costs like taxes, insurance, HOA, utilities you pay, management, maintenance, and capex reserves. Exclude mortgage principal and interest.
Should I include capex and maintenance reserves?
Yes—especially when screening. If you don’t reserve for repairs and replacements, deals can look better on paper than they perform in reality.
