Show the math

Cap rate measures the property; cash-on-cash measures your invested cash:

NOI = rent − vacancy − operating expenses

cap rate = NOI ÷ price ·   cash-on-cash = annual cash flow ÷ cash invested

Operating expenses exclude the mortgage; cash flow is what's left after debt service. Estimates only, verify rents, taxes, and upkeep before investing. All math runs locally in your browser.

What this does

A rental property ROI calculator analyses a rental end to end (net operating income, cap rate, annual and monthly cash flow, and cash-on-cash return) from price, financing, rent, vacancy, and expenses.

How it works

NOI is effective rent (after vacancy) minus operating expenses, before the mortgage. Cash flow then subtracts debt service; cash-on-cash divides annual cash flow by the cash you invested.

How to use it

  1. Enter the price, financing, and rent.
  2. Add vacancy and operating expenses.
  3. Read NOI, cap rate, and cash flow.
  4. See your cash-on-cash return.

Understanding your result

NOI and cap rate describe the property independent of financing, so deals compare fairly. These figures are estimates, verify rents, taxes, and upkeep before investing.

Example

A property with $12,000 of NOI bought for $200,000 has a 6% cap rate.

What is cash-on-cash return?

Annual pre-tax cash flow divided by the total cash you invested (down payment, closing costs, and rehab). It measures the return on your actual out-of-pocket money.

Why exclude the mortgage from NOI?
