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 entirely, CoC measures your actual levered return on the money you invested out of pocket. That distinction matters. Two investors can buy the same property, and if one puts 20% down while the other puts 25% down, their CoC returns will be different even though the property itself has not changed. CoC is about your deal, not just the property.

The Formula

The calculation is simple:

CoC Return = Annual Pre-Tax Cash Flow / Total Cash Invested

A 10% CoC means you are earning $10 of annual cash flow for every $100 you invested.

Annual pre-tax cash flow is your total rental income minus everything: vacancy, insurance, property 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. If you furnished a short-term rental with $15,000 in furniture, that goes into the denominator too.

A Worked Example

Say you buy a rental property for $200,000. You put 20% down ($40,000) and pay $6,000 in closing costs, so your total cash invested is $46,000. The property rents for $1,800 per month.

On the income side, gross annual rent is $21,600. After subtracting 5% vacancy ($1,080), insurance ($1,800), taxes ($2,400), property management at 8% ($1,642), CapEx reserves at 5% ($1,026), and annual mortgage payments ($12,780), your net cash flow is $872 per year.

CoC Return = $872 / $46,000 = 1.9%.

That is a low return, and it tells you this deal is not a strong cash flow play at current prices and rates. You are barely earning more than a savings account on the cash you have tied up. But CoC is only one piece of the puzzle. If the property is in a strong appreciation market, the total return story might be very different when you factor in equity growth over time. That is where metrics like IRR come in.

What Is a Good Cash-on-Cash Return?

There is no universal answer, but most investors target somewhere between 8% and 12% for a traditional buy-and-hold rental. That range gives you meaningful income relative to the cash you have at risk.

In high-appreciation markets like coastal cities or fast-growing metros, investors often accept lower CoC returns, sometimes 4% to 6% or even lower, because they expect property values and rents to grow significantly. In those markets, the return story is weighted toward appreciation and equity growth rather than year-one cash flow.

In cash-flow-oriented markets like parts of the Midwest and Southeast, you can find deals in the 10% to 15% range or higher. Properties there tend to be priced primarily on their income, and investors in those markets rely on CoC as a primary screening tool.

The right target depends on your investment goals, your market, and how much you value cash flow versus long-term appreciation.

How Leverage Affects CoC

Because CoC is a levered metric, your financing terms have a huge impact on the number. A lower interest rate means lower mortgage payments, which means more cash flow and a higher CoC. A higher LTV (putting less down) means less cash invested, which also pushes CoC up, though it increases your monthly debt service at the same time.

Leverage cuts both ways. When things go well, leverage amplifies your return. When rental income drops or expenses rise, a highly leveraged deal can quickly turn cash-flow negative. This is why stress-testing your deal under different vacancy and rent scenarios is so important. A deal that shows an 8% CoC under your base assumptions might show a negative CoC at 10% vacancy.

CoC and the BRRRR Strategy

The BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat) often produces unusually high or even infinite CoC returns. The reason is math, not magic. If you invest $50,000 into a property, complete the rehab, refinance, and get $48,000 back, your cash left in the deal is only $2,000. Even modest annual cash flow of $1,200 on $2,000 of remaining investment produces a 60% CoC return.

If the refinance returns all of your capital, the denominator goes to zero and the CoC is technically infinite. This is powerful, but it should be interpreted carefully. You still have a mortgage to service regardless of what the CoC number says. The monthly cash flow in absolute dollars matters just as much as the percentage.

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. A deal with a great CoC in year one might look very different over a decade if rents stagnate or expenses grow faster than income.

That is why experienced investors look at CoC alongside other metrics. IRR captures the full return over time, including appreciation and the eventual sale. MOIC (Multiple on Invested Capital) tells you how many times you got your money back. NOI (Net Operating Income) shows the property's earning power before financing. Each metric answers a different question, and the best analysis uses all of them together.
