Cash on Cash Return Calculator

Cash-on-cash return (CoC) is a metric that measures the annual pre-tax cash income earned on the cash invested in a property. It's calculated by dividing the property's annual pre-tax cash flow by the total cash invested, expressed as a percentage. It's one of the most commonly used metrics in rental property analysis.

The formula is: Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100. Annual cash flow is your gross rental income minus vacancy losses, operating expenses, and annual debt service (mortgage payments). Total cash invested includes your down payment, closing costs, and any upfront repair costs.

A CoC return of 8–12% is generally considered good for most rental property investors, though expectations vary by market and risk tolerance. Some investors in high-appreciation markets accept lower CoC returns (4–6%) while those focused purely on cash flow typically target 10% or higher.

ROI (Return on Investment) accounts for the total return on a property including appreciation, equity build-up, tax benefits, and cash flow — often measured over the full holding period. Cash-on-cash return only measures the annual cash income relative to the cash invested, ignoring appreciation and equity. CoC is useful for year-by-year cash flow analysis, while ROI gives a broader long-term picture.

Your initial cash investment should include the down payment, loan origination points, and all closing costs such as escrow fees, title insurance, and appraisal fees. Some investors also include upfront repair or renovation costs needed to make the property rent-ready.

Operating expenses typically include property taxes, insurance, property management fees, maintenance and repairs, landscaping, utilities (if landlord-paid), HOA fees, and vacancy reserves. Mortgage principal and interest payments are NOT operating expenses — they are captured separately as debt service.

Yes — debt service (your annual principal + interest payments) is subtracted from Net Operating Income to arrive at your pre-tax cash flow, which is the numerator in the CoC formula. This makes CoC a leveraged return metric that reflects the actual cash you pocket after making loan payments.

Cash-on-cash return is a snapshot metric — it only reflects a single year and does not account for property appreciation, equity paydown from mortgage amortization, tax deductions, or the time value of money. Use it alongside other metrics like cap rate, IRR, and total ROI for a complete picture of an investment's performance.
