Cash-on-Cash Return Explained
Cash-on-cash return measures annual pre-tax cash flow against the cash you put into the property. It changes when the loan changes. Cap rate does not.
Quick answer
Divide annual pre-tax cash flow by total cash invested. Cash flow of $40,000 on $500,000 invested is an 8% cash-on-cash return. The result is an illustration, not a tax calculation and not an internal rate of return.
Key takeaways
- Cash-on-cash = annual pre-tax cash flow ÷ cash invested.
- It is after debt service. Cap rate is before debt.
- A larger loan can raise the ratio while raising the risk.
- Taxes are intentionally left out. Ask your tax advisor before you rely on a return.

The formula and an example
Annual pre-tax cash flow ÷ total cash invested
| Line | Amount |
|---|---|
| NOI | $130,000 |
| Annual debt service | $90,000 |
| Pre-tax cash flow | $40,000 |
| Cash invested | $500,000 |
| Cash-on-cash return | 8.00% |
The calculator will do the division. It will not build the cash flow for you. You still have to get from NOI to cash flow by subtracting the debt service you are actually assuming.
How it differs from cap rate
Cap rate ignores the loan. Two buyers can pay the same price, use the same NOI, and show different cash-on-cash returns because one borrowed more or paid a different rate. That is useful. It is also how a thin equity slice can look brilliant until the balloon or a vacancy arrives.
Cash invested should include the down payment and the closing cash you will not get back as a loan. If you omit closing costs, the return is overstated. If the property needs immediate capital work, decide whether that cash belongs in the denominator.
What this return is not
It is not an internal rate of return. It looks at one year, not the sale in year seven. It is not after tax. Depreciation, cost segregation, and your own bracket are outside this page on purpose. Nothing here is tax, legal, or lending advice.
Using it in Omaha and Lincoln
The formula does not change between the metros. Insurance, taxes, and the rent that supports NOI do. Use the property’s own bills, then talk with Bryan if you want a second set of eyes on the commercial logic. Loan rates come from a lender’s term sheet.
Questions people ask
Can cash-on-cash be negative?
Yes. If debt service is higher than NOI, pre-tax cash flow is negative and the return is negative. The calculator will show that. It is a result, not an error.
Should I use before-tax or after-tax cash flow?
This site uses pre-tax cash flow so the illustration does not pretend to know your taxes.
What if I pay all cash?
Cash invested is the purchase cash, and cash flow is NOI minus any reserves you include. There is no debt service to subtract. The ratio can look lower than a leveraged return and still be the safer structure.
