Cap rate and cash-on-cash return are the two numbers investors quote most often, and they are often confused. They answer different questions:
- Cap rate asks: how much income does this property produce relative to its price?
- Cash-on-cash return asks: how much cash does my investment produce relative to the cash I put in?
The difference is financing. Cap rate ignores it. Cash-on-cash return depends on it.
Cap Rate
Cap rate = Net operating income ÷ Purchase price
Because it leaves out financing, cap rate lets you compare properties on equal terms, whether one buyer pays cash and another borrows. It is also how income properties are often valued: if similar buildings trade at similar cap rates, the NOI points to a price range.
Cap rate is only as good as the NOI behind it. See how to calculate NOI.
Cash-on-Cash Return
Cash-on-cash return = Annual pre-tax cash flow ÷ Total cash invested
Where:
- Annual pre-tax cash flow = NOI − annual debt service (mortgage principal and interest)
- Total cash invested = down payment + closing costs + any immediate repairs or reserves you fund at purchase
This is the return on your own money in a given year.
A Hypothetical Example
The figures below are hypothetical and for illustration only. The interest rate is an assumption, not a rate quote.
A property is priced at $1,000,000 with an NOI of $55,000. Closing costs are assumed to be $25,000.
Cap rate: $55,000 ÷ $1,000,000 = 5.5%
Now compare three ways to buy it:
| All cash | 40% down | 25% down | |
|---|---|---|---|
| Loan amount | $0 | $600,000 | $750,000 |
| Cash invested (down payment + closing) | $1,025,000 | $425,000 | $275,000 |
| Annual debt service (7%, 30-year) | $0 | $47,902 | $59,877 |
| Annual cash flow (NOI − debt service) | $55,000 | $7,098 | −$4,877 |
| Cash-on-cash return | 5.4% | 1.7% | Negative |
| Debt service coverage (NOI ÷ debt service) | n/a | 1.15 | 0.92 |
The cap rate is 5.5% in every column. The cash-on-cash return is not.
What the Example Shows
Leverage works both ways. Borrowing increases your return only when the property earns more than the loan costs. In this example the loan’s annual cost (about 8% of the loan amount, including principal) is higher than the property’s 5.5% yield, so each borrowed dollar lowers cash flow. With 25% down, the property does not cover its payments at all.
Debt coverage matters to lenders. At 25% down, NOI covers only 92% of the payments. Many lenders would not make that loan, or would require a larger down payment. Investment-property lenders set their own minimum coverage ratios.
Cash flow is not the whole return. Cash-on-cash return leaves out appreciation, principal paydown and tax effects. An investor may accept low cash flow in exchange for expected appreciation, but that is a different risk, and it should be a deliberate choice rather than a surprise.
Which One Should You Use?
Use both, for different purposes:
- Cap rate to compare properties and to judge whether a price is in line with the income.
- Cash-on-cash return to see what your actual investment produces with the financing you can get.
- Debt service coverage to check that the property can carry its loan, with a margin for vacancies and repairs.
In South Florida, where insurance, taxes and association costs can change quickly, it is worth stress-testing all three: what happens if insurance rises, a unit sits vacant, or rates are higher at refinance?

Frequently Asked Questions
Is a higher cap rate always better?
Not necessarily. A higher cap rate means more income relative to price, but it can also reflect more risk, an older property, a weaker location or more management work. Compare cap rates only between similar properties.
Can cash-on-cash return be negative?
Yes. If annual debt service is higher than the property's NOI, cash flow is negative, and so is the cash-on-cash return, even when the cap rate looks reasonable.
What is DSCR?
The debt service coverage ratio is NOI divided by annual debt payments. A ratio below 1.0 means the property's income does not cover its loan payments. Lenders, including DSCR lenders, set their own minimum ratios.
Does cash-on-cash return include appreciation or loan paydown?
No. It measures only the cash the property produces in a year relative to the cash you invested. Appreciation, principal paydown and tax effects are part of total return and are evaluated separately.
