What Is Cash-on-Cash Return? (And How to Calculate It)

Cash-on-Cash return (CoC) is one of the most important metrics in real estate investing. It answers a straightforward question: for every dollar of cash I put into this deal, how much cash am I getting back each year? Unlike cap rate, which ignores financing, CoC measures your actual levered return on the money you invested out of pocket.

The Formula

Annual pre-tax cash flow is your total rental income minus all expenses: vacancy, insurance, taxes, property management, maintenance reserves, and mortgage payments. Total cash invested includes your down payment, closing costs, rehab costs, and any other cash you put in at acquisition.

A Worked Example

Let's say you buy a rental property with the following numbers:

CoC Return = $872 / $46,000 = 1.90%. That is a relatively low return, which tells you this deal might not be a strong cash flow play at current prices and rates. But CoC is only one piece of the puzzle.

What Is a Good Cash-on-Cash Return?

There is no universal answer, but most investors target somewhere between 8% and 12% for a buy-and-hold rental. In high-appreciation markets, investors may accept lower CoC (even 4-6%) because they expect property values and rents to grow significantly. In cash-flow markets, you might find deals at 10-15% or higher. The right target depends on your investment goals, market conditions, and how much you value cash flow versus appreciation.

CoC vs. Other Metrics

CoC only measures year-one cash flow relative to your investment. It does not account for appreciation, loan paydown, tax benefits, or what happens over the full hold period. That is why experienced investors look at CoC alongside other metrics like IRR (Internal Rate of Return, which captures the full return over time), MOIC (Multiple on Invested Capital), and NOI (Net Operating Income). The Quick Real Estate Analyzer calculates all of these from a single set of inputs.

How Leverage Affects CoC

Because CoC is a levered metric, your financing terms have a huge impact. A lower interest rate or higher LTV means less cash invested and potentially higher CoC. But leverage cuts both ways: if your rental income drops or expenses rise, a highly leveraged deal can quickly turn negative. This is why the sensitivity analysis in our tool is so valuable. It shows how your CoC changes across different vacancy and rent scenarios so you can see where your breakeven points are.

BRRRR and Cash-on-Cash

The BRRRR strategy often produces unusually high (or even infinite) CoC returns because the refinance pulls most of your cash back out. If you invest $50,000, refinance and get $48,000 back, your cash left in the deal is only $2,000. Even modest cash flow on $2,000 of remaining investment produces an enormous percentage return. This is powerful but should be interpreted carefully, since you still have a mortgage to service regardless of your CoC number.
