What Is Rental Cash Flow?
Rental cash flow refers to the net income generated from a rental property after all operating expenses and loan payments have been deducted from the gross rental income.
In simple terms:
Cash Flow = Total Rental Income – Total Expenses
Positive cash flow means the property is profitable. Negative cash flow indicates you are losing money each month.

Example Calculation
Let’s look at an example to better understand:
- Monthly Rental Income: $2,000
- Operating Expenses:
- Property Tax: $150
- Insurance: $80
- Maintenance: $100
- Management Fees: $100
- Utilities: $50
- Monthly Loan Payment: $1,000
Step 1: Total Operating Expenses
= $150 + $80 + $100 + $100 + $50
= $480
Step 2: Net Operating Income (NOI)
= $2,000 – $480
= $1,520
Step 3: Cash Flow
= $1,520 – $1,000
= $520
Result: You earn $520/month in positive cash flow.
