About the Cash-on-Cash Return Calculator
The Cash-on-Cash Return Calculator measures annual pretax property cash flow after debt service relative to the cash initially invested. It helps real estate investors assess the cash income generated by their upfront investment, rather than changes in property value. With annual cash flow of $7,200 and initial cash invested of $90,000, the cash-on-cash return is 8%.
- Annual cash flow after debt service ($)
- The annual pretax cash remaining after property operating expenses and mortgage principal and interest payments, entered in dollars; the default is $7,200.
- Initial cash invested ($)
- The total upfront cash committed to the property, typically including the down payment, closing costs, and initial improvements, entered in dollars; the default is $90,000.
Formula and method
R = (C / I) × 100; with the defaults, R = (7200 / 90000) × 100 = 8%.
- RAnnual cash-on-cash return, expressed as a percentage.
- CAnnual pretax property cash flow after debt service, in dollars.
- IInitial cash invested in the property, in dollars; must be greater than zero.
Divide annual pretax cash flow after debt service by initial cash invested, then multiply by 100 to express the ratio as a percentage. Using the defaults, $7,200 divided by $90,000 equals 0.08, which becomes an 8% cash-on-cash return.

How to use the Cash-on-Cash Return Calculator
- 1Determine the property's annual pretax cash flow after operating expenses and debt service, including both mortgage principal and interest payments.
- 2Enter that amount in Annual cash flow after debt service ($); the default is 7200.
- 3Add up the cash initially committed to the investment and enter it in Initial cash invested ($); the default is 90000.
- 4Confirm that both amounts are in dollars and that initial cash invested is greater than zero, then calculate.
- 5Read the cash-on-cash return percentage; the default inputs produce 8%.
Reading your result
The Cash-on-cash return output row shows annual pretax cash flow as a percentage of initial cash invested. The default result of 8% means the property generates $7,200 in annual pretax cash flow after debt service relative to $90,000 invested upfront. A positive result indicates positive cash flow, zero indicates no cash flow remaining, and a negative result indicates a cash shortfall. This is a cash-income measure, not the property's total investment return.
Limitations
The calculation assumes a full year of cash flow and a positive initial cash investment. It does not independently estimate rent, vacancy, repairs, operating expenses, or debt service; those must already be reflected appropriately in the cash-flow input. It excludes income taxes, appreciation, sale proceeds, and the equity benefit of mortgage principal repayment, although principal payments reduce the cash-flow input. It also ignores the timing of cash flows and later capital contributions, so it is not an annualized total-return or internal-rate-of-return calculation. Results depend on consistent treatment of reserves and capital spending and do not guarantee future performance.
Common questions
Should mortgage principal payments be deducted from annual cash flow?+
Yes. Debt service includes both principal and interest, so both reduce the cash flow entered here. Principal repayment may build equity, but this calculator measures available cash income rather than equity growth.
Does initial cash invested mean the property's purchase price?+
Not necessarily. For a financed purchase, use the cash you contributed, typically the down payment plus closing costs and initial improvements, rather than the amount borrowed. For an all-cash purchase, include the purchase price and other upfront cash costs.
Is cash-on-cash return the same as capitalization rate?+
No. Cash-on-cash return divides cash flow after debt service by initial cash invested. Capitalization rate generally divides net operating income before debt service by property value or purchase price, so financing affects the two measures differently.
Can I use negative cash flow or zero initial cash invested?+
Negative annual cash flow can be used and produces a negative cash-on-cash return when initial cash invested is positive. Zero initial cash invested makes the ratio undefined because it requires division by zero; this calculator requires a positive investment amount.
