How it works

Cash-on-cash return divides one year of pre-tax cash flow by the total cash you invested. Unlike cap rate, it depends on your financing: change the loan and the result changes even though the property is identical.

Include every dollar you put in — down payment, closing costs, lender fees, and money spent to make the property rentable.

Formula

Total cash invested

Down payment + Closing + Rehab + Other

Cash-on-cash

Annual pre-tax cash flow ÷ Total cash invested × 100

Worked example

With the hypothetical defaults ($3,000 annual cash flow, $87,500 total cash):

Cash-on-cash return3.43%
Total cash invested$87,500

All figures in this example are hypothetical and chosen to illustrate the math. They are not current Houston market averages, quotes, or forecasts.

Frequently asked questions

Does cash-on-cash include principal paydown?

No. Principal paydown builds equity but is not cash you receive, so it is excluded.

Can cash-on-cash be negative?

Yes — when debt service exceeds NOI, annual cash flow is negative.
