Cash-on-Cash Return Explained: Formula, Example and Traps
By the Blurben team · · 6 min read
Cash-on-cash return is the yearly cash a rental puts in your pocket, before income tax, divided by the cash you put into the deal. If you invest $60,000 of your own money and the property leaves you $3,000 a year after every expense and mortgage payment, your cash-on-cash return is 5 percent. It is the quickest way to see what your own money earns once financing is included, and with the 30-year fixed mortgage averaging 7.24 percent in Freddie Mac's survey for the week of October 29, 2026 (Freddie Mac), the loan can change the answer more than most buyers expect. This guide shows the formula, a full worked example, and the traps that make the number look better than it is.
The formula
Cash-on-cash return = annual pre-tax cash flow ÷ total cash invested
That is the standard definition: the ratio of annual before-tax cash flow to the total cash invested, expressed as a percentage (Wikipedia). Each side needs care.
Annual pre-tax cash flow is what is left after a full year of:
- rent actually collected, after a vacancy allowance
- operating expenses: property tax, insurance, repairs, management, utilities you pay, HOA fees and a capital reserve
- mortgage payments, both principal and interest
Total cash invested is every dollar you bring, not just the down payment. The Motley Fool notes that cash invested includes the down payment plus any additional out-of-pocket fees paid to close the deal (The Motley Fool). In practice that also means loan fees, inspections and any repairs you pay for before the first tenant moves in.
A worked example (illustrative numbers only)
The figures below are made up to show the math. They are not market data. The loan rate is the Freddie Mac weekly average quoted above; your actual rate on a rental will come from your lender.
Cash you put in
| Item | Amount |
|---|---|
| Down payment (25% of a $200,000 price) | $50,000 |
| Closing costs and loan fees | $6,000 |
| Repairs before renting | $4,000 |
| Total cash invested | $60,000 |
One year of operations
| Line item | Annual amount |
|---|---|
| Gross rent ($2,100 × 12) | $25,200 |
| Vacancy allowance (8%) | −$2,016 |
| Operating expenses | −$8,000 |
| Net operating income (NOI) | $15,184 |
| Mortgage payments ($150,000, 30 years, 7.24%) | −$12,267 |
| Pre-tax cash flow | $2,917 |
Cash-on-cash return = $2,917 ÷ $60,000 = 4.9%
The surprise: the loan can lower your return
Now run the same property bought for cash. You would invest $210,000 (price plus the same closing costs and repairs) and keep the full $15,184 of NOI, because there is no mortgage. That is a cash-on-cash return of about 7.2 percent, higher than the 4.9 percent with the loan.
Why? Each year this loan costs about 8.2 percent of its balance in payments ($12,267 ÷ $150,000). The property earns about 7.2 percent on what it costs you in total. When borrowed money costs more than the property earns, every borrowed dollar pulls your return down. When it costs less, borrowing pushes your return up. This is often called negative or positive leverage, and it is the single most useful thing cash-on-cash return can show you.
The loan still leaves more of your cash free for reserves or other uses. The point is not that borrowing is good or bad, but that you should see the effect in numbers before you sign.
How sensitive the number is
Using the same example, here is how small changes move the result:
| Change | Pre-tax cash flow | Cash-on-cash return |
|---|---|---|
| Base case | $2,917 | 4.9% |
| Insurance quote $1,500 higher | $1,417 | 2.4% |
| 20% down instead of 25% | $2,099 | 4.2% |
| 30% down instead of 25% | $3,735 | 5.3% |
| Rate one point lower (6.24%) | $4,113 | 6.9% |
A single expense surprise cut the return by half. That is why the inputs matter more than the formula.
What is a good cash-on-cash return?
There is no official benchmark. The Motley Fool describes at least 8 percent as a rule of thumb, while stressing that a good figure depends on the investor and the type of property (The Motley Fool). More useful than any target is to compare the number with three things:
- Your other options for the same cash, at a similar level of risk and effort.
- The cap rate on the same property. If your cash-on-cash return is far below the cap rate, the loan is working against you. Our guide on what is a good cap rate explains how to judge that side.
- Your own goal. Some buyers want steady income now; others accept thin cash flow in exchange for expected rent growth or paying down the loan.
What cash-on-cash return leaves out
It is a first-year snapshot of cash, so it ignores several things that affect your total result:
- Loan paydown: the principal part of each payment builds equity but is counted as an outflow.
- Appreciation or decline in the property's value.
- Income tax: the figure is before tax and cannot take into account an individual investor's tax situation (Wikipedia).
- Future years: rents, expenses and vacancy change, so the return changes too.
Treat it as a screening tool, then look at the full picture.
Checklist before you trust the number
- Use market rent from recent comparable leases, not the seller's projection.
- Include a vacancy allowance, even for a property that is rented today.
- Get the real property tax bill and a written insurance quote for this address.
- Include management and a capital reserve, even if you plan to manage it yourself.
- Use a real loan quote for an investment property, not an advertised average.
- Count every dollar of cash in: down payment, closing costs, loan fees, inspections and early repairs.
- Recalculate with higher expenses and a higher rate to see how much room you have.
- Compare the result with the cap rate to see whether the loan helps or hurts.

Frequently asked questions
What is cash-on-cash return in simple terms?
It is the yearly pre-tax cash flow from a property divided by the total cash you put in, shown as a percentage. It tells you what your own money earns in a year after expenses and mortgage payments.
How do you calculate cash-on-cash return?
Take one year of rent after vacancy, subtract operating expenses and all mortgage payments to get pre-tax cash flow, then divide by your total cash invested: down payment, closing costs, loan fees and early repairs.
Is cash-on-cash return the same as cap rate?
No. Cap rate uses net operating income before mortgage payments, divided by the price. Cash-on-cash return includes the mortgage and divides by your own cash, so it shows the effect of financing.
Can cash-on-cash return be negative?
Yes. If mortgage payments and expenses are larger than the rent you collect, cash flow is negative and so is the return. This is more likely when the loan costs more each year than the property earns.
