Formula
Cash-on-Cash Return = Annual Pre-Tax Cash Flow / Total Cash Invested x 100
Where Annual Pre-Tax Cash Flow equals effective gross income (rent minus vacancy) minus all operating expenses and mortgage payments, and Total Cash Invested equals down payment plus closing costs plus renovation costs.
Worked Examples
Example 1: Single Family Rental Analysis
Problem: Purchase price $250,000, down payment $50,000, closing costs $6,000, monthly rent $1,800, mortgage $1,100/mo, taxes $200/mo, insurance $100/mo, maintenance $100/mo, 5% vacancy.
Solution: Total cash invested = $50,000 + $6,000 = $56,000\nAnnual gross rent = $1,800 x 12 = $21,600\nEffective gross income = $21,600 x 0.95 = $20,520\nAnnual mortgage = $1,100 x 12 = $13,200\nAnnual expenses = ($200 + $100 + $100) x 12 = $4,800\nAnnual cash flow = $20,520 - $13,200 - $4,800 = $2,520\nCash-on-Cash = $2,520 / $56,000 = 4.50%
Result: Cash-on-Cash Return: 4.50% | Monthly Cash Flow: $210
Example 2: High Cash Flow Duplex Investment
Problem: Purchase price $180,000, down payment $36,000, closing costs $4,500, renovation $10,000, total rent $2,400/mo, mortgage $850/mo, taxes $150/mo, insurance $90/mo, maintenance $120/mo, management $240/mo, 8% vacancy.
Solution: Total cash invested = $36,000 + $4,500 + $10,000 = $50,500\nAnnual gross rent = $2,400 x 12 = $28,800\nEffective gross income = $28,800 x 0.92 = $26,496\nAnnual mortgage = $850 x 12 = $10,200\nAnnual expenses = ($150 + $90 + $120 + $240) x 12 = $7,200\nAnnual cash flow = $26,496 - $10,200 - $7,200 = $9,096\nCash-on-Cash = $9,096 / $50,500 = 18.01%
Result: Cash-on-Cash Return: 18.01% | Monthly Cash Flow: $758
Frequently Asked Questions
What is cash-on-cash return and why is it important for real estate investors?
Cash-on-cash return (CoC) is a metric that measures the annual pre-tax cash flow generated by a real estate investment relative to the total cash invested. It is calculated by dividing the annual net cash flow by the total cash outlay, which includes the down payment, closing costs, and any renovation or repair expenses. Unlike cap rate which ignores financing, cash-on-cash return accounts for mortgage payments and shows the actual return on your out-of-pocket investment. This makes it extremely useful for comparing leveraged investment opportunities. A CoC return of 8 to 12 percent is generally considered good, while anything above 12 percent is excellent for most residential markets.
How is cash-on-cash return different from cap rate and ROI?
These three metrics each serve a different purpose in real estate analysis. Cash-on-cash return measures actual cash flow relative to cash invested and includes financing costs like mortgage payments. Cap rate (capitalization rate) measures net operating income relative to property value and ignores financing entirely, making it useful for comparing properties regardless of how they are purchased. Total ROI (return on investment) accounts for all returns including appreciation, principal paydown, and tax benefits in addition to cash flow. Cash-on-cash is best for evaluating year-one cash performance, cap rate for comparing market values, and ROI for long-term wealth building assessment across your portfolio.
What is a good cash-on-cash return for rental property investments?
What constitutes a good cash-on-cash return depends on the market, property type, and investor goals. In general, a CoC return between 8 and 12 percent is considered solid for residential rental properties. In high-cost appreciation markets like San Francisco or New York, investors may accept 3 to 5 percent CoC returns because they expect significant property appreciation. In cash-flow-focused markets in the Midwest or Southeast, investors often target 10 to 15 percent or higher. Commercial properties may yield 6 to 10 percent. Remember that CoC return should be evaluated alongside other factors such as appreciation potential, neighborhood trends, tenant quality, and your personal risk tolerance before making a final investment decision.
How does leverage affect cash-on-cash return?
Leverage (using borrowed money through a mortgage) can dramatically amplify cash-on-cash returns compared to buying with all cash. For example, a property generating $12,000 in annual cash flow purchased for $200,000 all-cash yields a 6 percent CoC return. But if you put 20 percent down ($40,000) and the mortgage payment leaves $6,000 annual cash flow, your CoC return is 15 percent because you only invested $40,000. However, leverage is a double-edged sword: if the property underperforms or vacancy rises, mortgage payments still must be made, potentially turning your CoC return negative. Higher leverage increases both potential returns and risk, which is why stress-testing your investment at various vacancy and expense levels is essential.
What expenses should I include when calculating cash-on-cash return?
A thorough cash-on-cash calculation should include all recurring expenses that affect your actual cash flow. On the income side, start with gross rental income and subtract a vacancy allowance, typically 5 to 10 percent depending on the local market. For expenses, include mortgage principal and interest payments, property taxes, property insurance, maintenance and repairs (commonly budgeted at 1 percent of property value annually), property management fees (usually 8 to 10 percent of collected rent), HOA fees if applicable, utilities paid by the owner, and any landlord-paid services. Do not include depreciation or amortization as these are non-cash accounting items. For the cash invested, include down payment, all closing costs, and any initial renovation or repair expenditures.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
