Cash on Cash Return Calculator

What Is Cash-on-Cash Return?

Cash-on-cash return measures the annual pre-tax cash flow you receive relative to the total cash you invested in a rental property. It answers the most fundamental investor question: “How much cash am I earning on the cash I put in?”

Unlike metrics that ignore financing, cash-on-cash return includes mortgage payments in its calculation. This makes it a levered return metric that reflects the actual experience of investing with a loan. Investors use it to compare rental properties against each other and against alternative investments like stocks, bonds, or REITs.

The cash on cash return calculator above computes this metric instantly from your property details, factoring in down payment, closing costs, vacancy, operating expenses, and debt service.

Cash-on-Cash Return Formula

The formula is:

Cash-on-Cash Return = Annual Pre-Tax Cash Flow / Total Cash Invested

Total cash invested includes everything you pay out of pocket: down payment, closing costs, and any rehab costs. For a $350,000 property with 25% down ($87,500) plus 3% closing costs ($10,500), your total cash invested is $98,000.

Annual pre-tax cash flow is your rental income minus vacancy, operating expenses, and annual debt service. If that property generates $6,000 in annual cash flow after all expenses and mortgage payments:

$6,000 / $98,000 = 6.1% cash-on-cash return

Closing costs are always included in total cash invested because they represent real cash out of your pocket. Enter your numbers above to calculate instantly.

How to Calculate Cash-on-Cash Return

Step 1: Calculate total cash invested. Add up every dollar you put into the deal:

• Down payment — the purchase price multiplied by your down payment percentage
• Closing costs — typically 2% to 5% of the purchase price (lender fees, title, appraisal, etc.)
• Rehab costs — any renovation expenses before the property is rent-ready

Step 2: Calculate annual pre-tax cash flow. Start with annual rental income and subtract:

• Vacancy — a percentage of gross rent to account for turnover and unleased periods
• Operating expenses — property taxes, insurance, maintenance, property management
• Annual debt service — your monthly mortgage payment multiplied by 12

Step 3: Divide. Annual cash flow divided by total cash invested gives you the cash-on-cash return as a decimal. Multiply by 100 for the percentage.

You can find operating expense estimates on the property listing, from your property manager, or by using the detailed mode in the calculator above.

What Is a Good Cash-on-Cash Return?

The 8% to 12% range is where most experienced investors aim. Here is how to interpret different ranges:

Context matters significantly. A 6% cash-on-cash return in a market with strong appreciation and rent growth may outperform a 10% return in a stagnant market when total return is considered. However, cash-on-cash focuses solely on the cash flow component.

Compare your rental property’s cash-on-cash return to what you could earn passively: the S&P 500 historically returns about 10% annually, while REITs have averaged 8% to 12%. Rental property offers additional benefits (tax deductions, leverage, equity buildup) that these comparisons do not capture.

Cash-on-Cash Return vs Cap Rate

These two metrics evaluate the same property from different perspectives:

Cash-on-cash return is a levered metric — it includes financing. Your down payment, interest rate, and loan term all affect the result. It measures the return on your personal cash investment.

Cap rate is an unlevered metric — it excludes financing entirely. It divides the property’s net operating income (NOI) by its price, showing the return as if you paid all cash.

When you use leverage with a favorable interest rate, your cash-on-cash return exceeds the cap rate. This is called positive leverage — the loan amplifies your return because the property earns more on the borrowed money than the interest costs. If your interest rate is too high, you get negative leverage, and cash-on-cash drops below the cap rate.

Limitations

Cash-on-cash return provides a useful annual snapshot, but it has boundaries:

• Ignores appreciation — property value increases are not captured, yet they often represent the largest component of total return in many markets.
• Ignores equity buildup — each mortgage payment reduces your loan balance, building equity that is not reflected in cash-on-cash.
• Ignores tax benefits — depreciation deductions can significantly improve after-tax returns.
• No time value of money — a dollar received in year one is weighted the same as year ten.
• Snapshot metric — it reflects one year’s performance. Rent growth, expense changes, and rate adjustments shift the number over time.

Use cash-on-cash return for initial screening and year-one analysis, but consider total return for long-term hold decisions.

Frequently Asked Questions

What is a good cash on cash return for rental property?

Most real estate investors target a cash-on-cash return between 8% and 12%. Markets with strong appreciation potential may justify lower cash-on-cash returns because total return includes equity growth. Below 5% may not compensate for the effort and risk of managing a rental property. Use the cash on cash return calculator above to see your property’s projected return.

How do I improve my cash on cash return?

The most effective levers are negotiating a lower purchase price, increasing rental income through renovations or market-rate adjustments, reducing operating expenses, and securing better financing terms such as a lower interest rate or higher leverage. The sensitivity analysis above shows how each variable shifts your return.

Does cash on cash include mortgage payments?

Yes. Cash-on-cash return accounts for debt service because it measures actual cash flow after all expenses including mortgage payments. Annual cash flow equals rental income minus vacancy, operating expenses, and debt service. This is what makes it a levered return metric.

What is the difference between ROI and cash on cash?

ROI (return on investment) often includes appreciation, equity buildup through principal paydown, and tax benefits. Cash-on-cash return is strictly cash flow divided by cash invested — it only measures the recurring income yield on your out-of-pocket investment. Both are useful but measure different things.

Is cash on cash return before or after taxes?

The calculator shows pre-tax cash-on-cash return. After-tax return depends on your marginal tax rate, depreciation deductions, mortgage interest deductions, and overall tax situation. Pre-tax CoC provides a consistent baseline for comparing properties regardless of the investor’s personal tax circumstances.
