Cash On Cash Return Calculator: Is That Rental Worth It?

Imagine you earn a $75,000 annual salary and want to diversify beyond your 401k. You find a $350,000 rental property. With a standard 20% down payment, you are sinking $70,000 of your liquid savings into this deal. Before you sign a 30-year mortgage at 6.5% APR, you need to know if the rent checks will actually provide a decent income stream. The Cash On Cash Return Calculator helps you determine exactly what percentage return you get on the actual cash you put down today, ignoring appreciation and focusing purely on cash flow.

How to Use

First, enter your total cash invested, including your down payment and closing costs. Next, input your annual pre-tax cash flow—gross rent minus mortgage payments, property taxes, and insurance. The calculator will instantly display your percentage return, allowing you to compare this property against other investment vehicles like stocks or bonds.

Pro Tips

Always compare your result to the S&P 500 average or your 401k performance. If you have a 6% employer match, a rental property yielding 3% might not be worth the hassle. Factor in the 6.5% interest rate environment; higher rates mean higher mortgage payments, which suppress cash flow. Lastly, be realistic about property management. If you hire a pro, subtract 8-10% of the rent to see your true passive income.

Common Mistakes to Avoid

First, forgetting closing costs is a classic error. On a $350,000 home, closing costs and rehab can add another $15,000 to your cash invested, significantly lowering your actual return. Second, ignoring vacancy rates will inflate your numbers. Even in good markets, plan for one month of vacancy per year. Finally, using gross rent instead of net cash flow leads to disaster. You must subtract your 6.5% mortgage interest payments, property taxes, and landlord insurance to get the real number.

Frequently Asked Questions

What is a good Cash on Cash return in the US?

Most investors aim for 8% to 12%. If you are buying in a high-appreciation market like California, you might accept 5%, while Midwestern investors often demand 15%+.

Does Cash on Cash include property appreciation?

No. It strictly measures annual cash flow against cash invested. To see total profit including value increases, you need to calculate your Internal Rate of Return (IRR).

How does a 6.5% mortgage rate affect my return?

Higher rates increase your monthly mortgage payment, reducing your annual cash flow. This lowers your percentage return unless you can put more money down to reduce the loan balance.
