Cash-on-cash return (CoC) measures the annual pre-tax cash income generated by a real estate or business investment relative to the equity invested — expressed as a percentage. Unlike IRR, CoC ignores time value of money and terminal value; it measures single-period cash yield only. See Federal Reserve Economic Data (fred.stlouisfed.org) for cap rate and property yield benchmarks.
Cash-on-cash return is a real estate investor's single-year yield metric. The formula is: CoC Return = Annual Pre-Tax Cash Flow / Total Cash Invested. 'Annual Pre-Tax Cash Flow' is the net operating income (NOI) minus debt service (mortgage principal + interest payments). 'Total Cash Invested' is the total equity deployed — down payment plus closing costs plus any immediate capital improvements. For a $1,000,000 apartment building purchased with $250,000 down, generating $90,000 NOI and $60,000 annual debt service, the annual pre-tax cash flow is $30,000 and the CoC return is 12% ($30K / $250K). This 12% measures the cash yield on equity in year one only. CoC vs IRR — the critical distinction: CoC is a single-period, non-discounted metric. It ignores: (1) appreciation in the property's value; (2) principal paydown (equity build-through amortization); (3) tax benefits (depreciation, interest deductibility); and (4) the terminal value (proceeds from eventual sale). IRR captures all of these by discounting the entire cash flow stream — initial investment, annual cash flows, and terminal sale proceeds — to a single annualized return figure. For investments held 5-10 years with significant appreciation potential, IRR diverges substantially from CoC. Institutional CRE investors typically underwrite to a minimum hurdle rate using IRR — not CoC — because IRR reflects the time-value of capital. CoC is most useful for cash flow-focused investors (retirees, income-oriented funds) who need current yield, not total return. Leverage and CoC: Higher leverage amplifies CoC return on equity but also amplifies downside. An all-cash purchase of the same property might generate 9% CoC (NOI/purchase price). Adding 75% LTV leverage at 7% interest with 25-year amortization might push CoC to 12-14% — but adds refinancing risk, interest rate risk, and default risk if NOI declines.

Context determines 'good.' In 2024-2025 CRE markets, 8-12% CoC return on leveraged residential multifamily is generally considered acceptable for value-add strategies; core (stabilized) assets often trade at 4-7% CoC given low cap rates. Compare against: (1) current treasury yields (the 'risk-free rate'); (2) local market cap rates (fred.stlouisfed.org/series/RECAPTS); and (3) your target IRR over the hold period. A 10% CoC with a high-growth property in a supply-constrained market may imply a 20%+ IRR; 10% CoC in a declining market with no appreciation may underperform on a total-return basis.
Cap rate = NOI / Property Value (ignores financing). CoC return = Cash Flow After Debt Service / Equity Invested (reflects your specific financing). Two investors buying identical properties at the same cap rate but with different financing terms will have different CoC returns. Cap rate is a property-level metric; CoC is an investor-level, leverage-adjusted metric. Neither captures appreciation or time value of money — for that, use IRR.
