📘 Cash Flow Formula in Plain Text
Let’s break down the cash flow formula using variables:
Monthly Cash Flow = Monthly Rental Income – Total Monthly Expenses – Monthly Debt Payment
Where:
- Monthly Rental Income = Rent collected per month
- Total Monthly Expenses = Operating costs (property taxes, insurance, repairs, etc.)
- Monthly Debt Payment = Mortgage or loan payment
Then:
Annual Cash Flow = Monthly Cash Flow × 12
📊 Example Calculation
Let’s say:
- Monthly Rent: $2,000
- Operating Expenses: $600 (includes taxes, insurance, HOA, vacancy reserves)
- Mortgage Payment: $1,000
Monthly Cash Flow = 2000 – 600 – 1000 = $400
Annual Cash Flow = 400 × 12 = $4,800
This shows a positive cash flow, making it a profitable investment.
