Quick Answer: Calculate cash-on-cash return by comparing annual pre-tax cash flow with total cash invested in a property.
How This Calculator Works
Cash-on-cash return measures leveraged cash yield. It includes debt service, unlike cap rate, and compares cash flow with the actual cash invested.
Worked Scenario: Scenario: Rental Property With Financing
An investor checks whether rental cash flow justifies the down payment and closing costs.
Scenario Inputs
- Annual rent: USD 50,400
- Debt service: USD 24,000
- Cash invested: USD 110,000
Outcome: The return shows annual cash flow as a percentage of cash invested before income tax and appreciation.
Formula and Methodology
Annual cash flow = Rental income - operating expenses - debt service
Cash-on-cash return = Annual cash flow / cash invested * 100
Payback period = Cash invested / annual cash flow
Variables
- Annual cash flow: Cash remaining before tax after expenses and loan payments
- Cash invested: Down payment, closing costs, repairs, and initial reserves
Assumptions
- Inputs are annual amounts.
- Income tax, appreciation, depreciation, and sale proceeds are excluded.
Limitations
- Negative cash flow produces a negative return and no practical payback period.
- Large repairs or vacancies can materially change the result.
Cash-on-cash return shows the financing impact
Rental property investors often use leverage, so cap rate alone is not enough. Cash-on-cash return asks what the investor earns on the cash actually placed into the deal.
The metric should be paired with vacancy stress tests and repair reserves because rental cash flow is rarely smooth.
Key Takeaways
- Include all cash invested, not only the down payment.
- Use annual debt service after financing terms are known.
- A positive return can still be fragile if reserves are too low.
Interpreting a low return
A low return may still be acceptable if the property has strong appreciation potential or strategic value, but that is a different thesis from income investing.
If the return depends on ignoring repairs, management, or vacancy, the deal is weaker than the headline suggests.
- Add closing costs to cash invested.
- Include management even if self-managing.
- Test several vacancy levels.
Leveraged returns need a reserve check
Cash-on-cash return can look strong because leverage is high. That same leverage increases downside risk when rent is late, expenses rise, or refinancing terms change.

Practical FAQs
How is this different from cap rate?
Cap rate excludes debt service and measures unlevered yield. Cash-on-cash includes debt service and measures return on invested cash.
Should repairs be included?
Recurring repairs should be included in operating expenses, and major capital repairs should be modeled separately.
Is cash-on-cash return after tax?
This calculator is pre-tax unless you manually include tax as an expense.
