Formula Used

The calculator uses the following formulas to determine investment metrics:

Return on Investment (ROI)

Cash Flow

Cash Flow = Total Income - Total Expenses

Payback Period

Payback Period = Purchase Price / Cash Flow

These formulas provide a comprehensive view of your real estate investment potential.

Worked Example

Let's look at an example calculation:

  • Down Payment: $60,000
  • Annual Rental Income: $28,000
  • Annual Expenses: $18,000
  • Holding Period: 5 years

Using these inputs, the calculator would show:

  • ROI: 12.5%
