Cash-on-Cash Return vs. ROI: What’s the Difference?
Cash-on-cash return and ROI are different measures. Cash-on-cash return measures annual pre-tax cash flow from a property against the cash you have invested. ROI measures the investment’s total profit relative to its cost over a stated period. A property can produce annual cash flow and also gain or lose value; those results should be evaluated separately.
| Measure | Cash-on-cash return | ROI |
|---|---|---|
| Main question | How much annual cash flow does my invested cash generate? | What is my total profit relative to the money invested? |
| Formula | Annual pre-tax cash flow ÷ cash invested × 100 | Total profit ÷ investment cost × 100 |
| Time period | Usually one year | A stated holding period; a multi-year ROI is not an annual return |
| Financing | Subtract annual debt service from operating cash flow | State whether you are measuring the property or the investor’s equity |
| Appreciation and sale | Exclude unrealized appreciation and sale proceeds from annual operating cash flow | Can include the net result of a sale; avoid counting the same gain twice |
How to calculate cash-on-cash return
Cash-on-cash return = annual pre-tax cash flow after debt service ÷ total cash invested × 100. Include the down payment, cash-paid acquisition costs, initial improvements and other equity contributions in the invested cash. Loan proceeds are borrowed funds, not an investor’s cash contribution.
Start with rental income after vacancy and collection loss, then subtract operating expenses such as property taxes, insurance, management, repairs and owner-paid utilities. This gives net operating income (NOI). For a simple example without capital expenditures or reserve movements, subtract debt service to reach pre-tax cash flow. In a full analysis, also account for cash spent on capital work and reserves, and state how those items are treated.
Debt service includes principal and interest payments. NOI is measured before financing costs. Cash flow after debt service is a separate figure. Principal paydown may build equity, but it is not cash distributed to the investor.
Example 1: Buying a rental property with cash
Assume a $250,000 purchase, $7,500 in cash-paid acquisition costs and no loan. Annual rent after any vacancy allowance is $24,000, and operating expenses are $8,000. Assume no additional capital spending or reserve contributions during the example year.
- Total cash invested: $250,000 + $7,500 = $257,500
- NOI: $24,000 − $8,000 = $16,000
- Annual debt service: $0
- Annual pre-tax cash flow: $16,000
- Cash-on-cash return: $16,000 ÷ $257,500 × 100 = 6.21%
Example 2: Buying the same property with financing
Keep the $250,000 purchase price and $16,000 NOI. Assume a 25% down payment, $7,500 in cash-paid acquisition costs and annual debt service of $9,000, including principal and interest. The debt service is an illustrative assumption, not a loan quote. Again, assume no additional capital spending or reserve contributions during the year.
- Down payment: 25% × $250,000 = $62,500
- Loan amount: $250,000 − $62,500 = $187,500
- Total cash invested: $62,500 + $7,500 = $70,000
- NOI remains: $16,000
- Annual pre-tax cash flow: $16,000 − $9,000 = $7,000
- Cash-on-cash return: $7,000 ÷ $70,000 × 100 = 10.00%
The acquisition costs do not reduce the purchase-money loan balance. In this example, financing raises the percentage return on invested cash while reducing annual cash flow. Higher debt payments, lower rent or additional expenses could reduce that return or make cash flow negative. These examples are hypothetical and do not represent current Hagerstown rents, financing terms or expected investment performance.
How ROI treats sale proceeds
For an equity investment held through sale, a simple total ROI can be calculated as: (cash distributions during ownership + net cash received at sale − total equity contributed) ÷ total equity contributed × 100. Net sale cash must reflect selling costs and the remaining loan payoff. Use consistent assumptions for expenses and taxes.
A sale can return the original investment as well as profit. Do not treat all sale proceeds as profit, and do not add appreciation or principal paydown again when they are already reflected in net sale cash. A multi-year ROI does not account for the timing of each contribution or distribution; IRR can help evaluate that timing.
What is a good cash-on-cash return?
There is no single target that suits every property or investor. Compare opportunities using consistent vacancy, expense, capital spending and financing assumptions. A high projected return may rely on optimistic rents, deferred repairs or greater borrowing risk. Review downside scenarios as well as the base case.
Cash-on-cash return does not capture every part of an investment. Review cash reserves, building condition, lease terms, future capital needs and the potential result at sale. For related analysis, see our commercial property valuation guide.
Evaluate a Hagerstown property
When reviewing investment opportunities, use the property’s rent roll, operating statements, tax and insurance costs, repair needs and actual financing proposal. Explore RG Realty’s Investor Resources or discuss a property with Roberto Gonzalez.
