How to Calculate Rental Property

What is Rental Property?

A rental property calculator evaluates the investment potential of a property using key metrics: cap rate, cash-on-cash return, and monthly cash flow. These metrics help compare properties and determine whether a rental generates acceptable returns for the risk.

  1. 1Cap Rate = Net Operating Income (NOI) / Property Value × 100
  2. 2NOI = Annual rent − Operating expenses (taxes, insurance, maintenance, vacancy)
  3. 3Cash-on-Cash Return = Annual cash flow / Down payment × 100
  4. 4Cash flow = Rent − Mortgage − Operating expenses
