Cash-on-Cash Return

While the cap rate measures the unlevered income yield of a property, cash-on-cash return measures the yield on the equity actually invested after accounting for financing costs. It answers the question: for every dollar of equity I put into this deal, how many cents of before-tax cash flow am I receiving per year? This makes it a more directly useful return measure for investors who are financing acquisitions with debt, since it captures the impact of leverage on current income.

The calculation is straightforward: annual pre-tax cash flow (NOI minus debt service) divided by total equity invested (down payment plus closing costs plus any upfront capital expenditures). If an investor purchases a $1,000,000 apartment building with a $250,000 down payment, closing costs of $15,000, and initial improvements of $35,000 — a total equity investment of $300,000 — and the property generates $20,000 of annual cash flow after paying the mortgage, the cash-on-cash return is 6.67%.

Cash-on-cash return is a first-year metric. It reflects current income but does not account for mortgage principal paydown, future rent growth, appreciation, or eventual sale proceeds. This distinguishes it from the internal rate of return, which captures all cash flows over the entire hold period including the exit. Sophisticated investors use cash-on-cash return as a quick screen for current income adequacy and then layer in IRR analysis to evaluate total return potential across multiple holding period scenarios.

Leverage meaningfully affects cash-on-cash returns. A property purchased entirely with cash — no mortgage — has a cash-on-cash return equal to its cap rate. Adding debt at an interest rate below the cap rate is said to be positive leverage: it increases cash-on-cash return above the unleveraged yield. Adding debt at an interest rate above the cap rate is negative leverage, which dilutes current income and is often seen on value-add or transitional deals where the acquisition yield is initially low but is expected to rise as the business plan executes.

For individual real estate investors evaluating rental properties, cash-on-cash return is one of the most intuitive and practical screening tools available. A target cash-on-cash return might be set at 6% to 8% for a stabilized property in a secondary market, while accepting a lower initial yield for a property in a high-growth primary market where rent appreciation potential justifies a compressed current return. Understanding how cash-on-cash return interacts with leverage, debt terms, and property operating expenses is foundational to any real estate underwriting process.
