Cash-on-Cash Return Calculator
Calculate the annual cash-on-cash return on a leveraged real estate investment. Ideal for landlords evaluating how efficiently their out-of-pocket capital is working after mortgage payments.
About this calculator
Cash-on-cash (CoC) return measures the annual pre-tax cash flow you receive relative to the total cash you invested out of pocket. The formula is: CoC Return = (Annual Cash Flow / Initial Cash Invested) × 100. Annual cash flow is gross rental income minus all operating expenses AND mortgage payments (debt service). Initial cash invested includes your down payment, closing costs, and any upfront renovation costs. Unlike cap rate, CoC return is financing-sensitive — a larger mortgage amplifies or diminishes returns depending on whether your yield exceeds your borrowing cost. This leverage effect is exactly why two investors buying the same property at the same price can have very different CoC returns. Most real estate investors target a CoC return of at least 8–12% to justify the illiquidity and management burden of direct property ownership.
How to use
You purchase a duplex for $300,000. You put 25% down ($75,000) and pay $3,000 in closing costs, so your initial cash invested = $78,000. After collecting rent and paying all expenses including the mortgage, your annual cash flow is $7,800. CoC Return = ($7,800 / $78,000) × 100 = 10.0%. This means you're earning 10 cents in cash for every dollar you deployed — a solid benchmark for a leveraged residential rental in most markets.
Frequently asked questions
What is a good cash-on-cash return for a rental property?
Most experienced investors look for a cash-on-cash return of at least 8–12% to make a leveraged rental worthwhile. Returns below 6% may struggle to outperform less-labor-intensive alternatives like index funds or REITs. However, acceptable returns depend on your local market, appreciation expectations, and tax benefits. In high-appreciation coastal markets, investors sometimes accept lower CoC returns in exchange for expected long-term equity gains.
How do I calculate annual cash flow for a cash-on-cash return calculation?
Annual cash flow starts with gross rental income, then subtracts vacancy allowance (typically 5–10%), property management fees, repairs and maintenance, insurance, property taxes, HOA fees, and finally annual mortgage payments (principal + interest). The result is your net cash flow — the actual dollars deposited into your account over the year. It's important to include all realistic expenses, not just mortgage payments, to avoid overestimating your return.
Why does using a mortgage change cash-on-cash return compared to an all-cash purchase?
When you buy with a mortgage, you invest less cash upfront, which can amplify your CoC return if the property's yield exceeds your borrowing cost — a concept called positive leverage. For example, if a property yields 8% cap rate and your mortgage rate is 6%, leverage boosts your CoC return above 8%. Conversely, if your mortgage rate exceeds the cap rate, leverage is negative and reduces your CoC return. This is why tracking both cap rate and CoC return together gives a complete picture of a leveraged investment's performance.
