Annual Before-Tax Cash Flow vs Annual NOI

Property Cash Flow

Cash flow is the money left over after paying all operating expenses, debt service, and setting aside reserves.

Formula

Cash Flow = NOI - Debt Service - Capital Reserves

Importance

  • Positive cash flow means the property pays for itself and generates income
  • Negative cash flow requires out-of-pocket funding each month
  • Cash flow funds your reserves, covers unexpected expenses, and provides income
  • Example Calculation

    A property has $42,000 annual NOI, $30,000 debt service, and $2,400 in capital reserves.

    1. 01Annual cash flow: $42,000 - $30,000 - $2,400 = $9,600
    2. 02Monthly cash flow: $9,600 / 12 = $800
    3. 03Cash flow margin: $9,600 / $42,000 x 100 = 22.9%
