How to use Rental Yield & Property ROI Calculator

Calculate gross rental yield, net rental yield, monthly cash flows, and Cash-on-Cash ROI for properties. Results are educational estimates, not official approval or advice.

  1. 1

    Enter total investment, rent and costs

    Add purchase and setup costs, achievable monthly rent, vacancy and recurring expenses; include financing only if comparing cash flow.

  2. 2

    Separate gross yield, net yield and cash flow

    Review each return measure with its own denominator, then check monthly cash flow and cash-on-cash return when available.

  3. 3

    Stress-test rent and vacancy

    Lower rent or occupancy and raise maintenance or financing cost to see whether the investment remains viable.

Before relying on the result
