What This Calculator Does

Evaluate rental property metrics including NOI, cap rate, cash flow, and cash-on-cash return.

It combines Purchase Price, Down Payment, Monthly Rent, Vacancy Rate to estimate Annual Cash Flow, NOI, Cap Rate.

Formula & Method

Core equations: Net operating income: NOI = R_{gross}(1 - v) - OpEx where v is the vacancy rate. Cap rate: \text{Cap} = \frac{NOI}{P} \times 100 Cash-on-cash return: \frac{NOI - \text{Debt Service}}{\text{Cash Invested}} \times 100 Inputs are applied in base units, then derived metrics are computed from the same equations and rounded for display.

Notation used in the formulas: R = Annual Cash Flow; x_{1} = Purchase Price; x_{2} = Down Payment; x_{3} = Monthly Rent; x_{4} = Vacancy Rate; x_{5} = Monthly Operating Expenses; x_{6} = Annual Debt Service.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
