What cash-on-cash return measures
Cash-on-cash return, also called cash yield, focuses on one period and one source of return: pre-tax cash generated relative to investor cash in the deal. Because debt service is subtracted before the ratio is calculated, changing the loan amount, rate, or amortization can change cash-on-cash return even when the property produces the same NOI.
The metric is useful for comparing the immediate cash profile of leveraged scenarios, but it is not a complete lifetime return. It does not automatically include appreciation, principal reduction, depreciation tax effects, refinancing, or sale proceeds. Use the rental property or IRR calculator when those components belong in the question.
Cash-on-cash return formula
EstateCalc first calculates potential income from scheduled rent and other recurring income. It subtracts the entered vacancy and collection loss, then operating expenses, to produce NOI. Annual debt service is subtracted from NOI to obtain annual pre-tax cash flow. Dividing that cash flow by the cash invested produces the percentage result.
The numerator and denominator must describe the same scenario. Do not divide a stabilized future cash flow by only the down payment while omitting closing costs and initial renovation cash. Conversely, do not include a refundable reserve or financed cost in cash invested unless it was actually funded by the investor and remains tied up in the deal.
What to include in cash invested
Cash invested commonly includes the down payment, buyer closing costs, lender points and fees paid in cash, due-diligence costs, initial repairs, and working capital or reserves funded at closing. Subtract immediate seller or lender credits only when they actually reduce the investor’s cash outlay. The property value input is not a substitute for this denominator.
If the investment changes after closing, label the period. A refinance that returns capital changes the cash remaining in the deal, while a later capital contribution increases it. This calculator is a transparent year-one snapshot; a multi-year equity history requires dated cash flows and an IRR or equity-multiple analysis.
Cash-on-cash return vs. cap rate and ROI
Cap rate divides NOI by property value and ignores financing. Cash-on-cash return subtracts debt service and divides by investor cash, so it reflects leverage. Two purchases of the same property can therefore have one cap rate but different cash-on-cash returns. Keep both metrics visible instead of treating them as interchangeable.
ROI is often used broadly and may include cash flow, price change, principal paydown, and sale proceeds over several years. Cash-on-cash return is narrower. EstateCalc does not label either percentage as attractive or unattractive because the relevant comparison depends on risk, liquidity, time horizon, and the assumptions being tested.
How to stress-test the result
Start with lease and operating-statement data you can verify. Then change one input at a time: vacancy, operating expenses, annual debt service, or initial cash. This shows whether the result is driven by property operations, financing, or an incomplete denominator.
Use a second scenario for known near-term changes such as a tax reassessment, insurance renewal, lease rollover, or interest-only period ending. Keep irregular capital work outside recurring expenses and test it separately so one large project does not become a hidden annual assumption.

The methodology is reviewed for the stated version. The result remains a scenario estimate and depends on the inputs and applicable rules.
Cash on Cash Return Calculator FAQ
What is the cash-on-cash return formula?
Cash-on-cash return equals annual pre-tax cash flow divided by actual cash invested, multiplied by 100%. EstateCalc calculates annual cash flow as effective property income minus operating expenses and annual debt service.
Is cash-on-cash return the same as cap rate?
No. Cap rate uses NOI and property value before financing. Cash-on-cash return uses cash flow after debt service and the investor’s cash contribution, so leverage affects it.
Does cash invested include closing costs and repairs?
Include closing costs, lender fees, initial repairs, and reserves when the investor pays them in cash for the scenario. Omitting them overstates the ratio by understating the denominator.
Does the calculation include mortgage principal paydown?
No. Principal is part of the entered debt-service cash outflow, but the increase in equity from principal reduction is not added as a return. Use a multi-year rental property model for that component.
Can cash-on-cash return be negative?
Yes. If NOI is lower than annual debt service, annual pre-tax cash flow and cash-on-cash return can be negative. The calculator reports the scenario without classifying it.
