Cash-on-Cash Return Calculator

Scope: Supporting copy only. The calculator tool itself is unchanged (CTO owns the logic).

If you buy an investment property with a mortgage, the return you actually feel in your bank account isn’t the same as the property’s overall yield — it’s driven by how much cash you put in versus how much cash comes back out each year. Cash-on-cash return measures exactly that: the annual pre-tax cash flow a property produces relative to the actual cash you invested to acquire it. Because it’s built around the cash you fronted (not the full purchase price), it’s the metric leveraged buyers use to compare deals where financing does a lot of the heavy lifting. This calculator estimates that percentage for a single property so you can sanity-check a deal before you commit capital.

How this calculator works

Cash-on-cash return uses a simple ratio:

Cash-on-cash return = annual pre-tax cash flow ÷ total cash invested

• Annual pre-tax cash flow is your net operating income (rental income minus operating expenses) minus your annual debt service (mortgage principal + interest), before income taxes. [Cash on Cash Return, Wikipedia, accessed July 3, 2026]
• Total cash invested is the actual cash you put into the deal: down payment + closing costs + any upfront rehab or make-ready costs.

The calculator divides the first by the second and expresses the result as a percentage.

Worked example (illustrative figures, not a quote for any specific property):

• Down payment: $50,000
• Closing costs: $6,000
• Upfront rehab: $9,000
• Total cash invested: $65,000

If the property throws off $5,850 in pre-tax cash flow in a year (after operating expenses and mortgage payments), the cash-on-cash return is:

$5,850 ÷ $65,000 = 0.09, or 9%

How this differs from cap rate: Cap rate divides net operating income by the property’s value or price and deliberately ignores financing — it describes the asset as if you bought it in all cash. Cash-on-cash return does the opposite: it factors in your mortgage, so two buyers looking at the same property can post very different cash-on-cash returns depending on how much they borrowed and on what terms. Use cap rate to compare properties as assets; use cash-on-cash to evaluate your specific, leveraged position. [Cash-on-Cash Return (COCR) in Real Estate, JPMorgan Chase, accessed July 3, 2026]

What’s a good cash-on-cash return?

There is no single “good” number, and any target you see quoted is a rule of thumb rather than a guarantee. What counts as attractive depends on your strategy (buy-and-hold vs. value-add vs. short-term rental), your local market, the interest-rate environment, and how much risk you’re taking on.

As a broad framing, many buy-and-hold investors talk about targeting returns in the high single digits to low double digits, and some published sources cite a common reference range of roughly 8% to 12%. [Cash on Cash Return, Wikipedia, accessed July 3, 2026]Treat that as context, not a promise: a higher headline return often reflects higher leverage or more risk, and a lower return isn’t automatically a bad deal if the property offers strong appreciation potential or stability. The right target is the one that clears your own cost of capital and risk tolerance.

What the metric ignores

Cash-on-cash return is a snapshot of current-year cash yield. By design, it leaves out several things that materially affect your total return:

• Appreciation. It measures only cash flow, not any change in the property’s market value.
• Principal paydown. The equity you build as tenants effectively pay down your loan isn’t captured, even though it’s real wealth accumulation.
• Taxes. The standard formula uses pre-tax cash flow, so it says nothing about your after-tax outcome, depreciation benefits, or your personal tax situation.
• Vacancy and other risks. A clean projected number assumes rents come in as modeled. Vacancy, delinquency, capital repairs, and rate changes on adjustable financing can all pull the realized return below the estimate.

Because of these gaps, cash-on-cash return is best used alongside other measures (cap rate, total ROI, and your own vacancy and reserve assumptions), not as the sole basis for a decision.

Frequently Asked Questions

How is cash-on-cash return different from ROI and cap rate?

ROI is a broad measure of total return that can include appreciation, principal paydown, and gains at sale. Cap rate divides net operating income by property value and ignores financing entirely. Cash-on-cash return sits between them: it includes your mortgage but looks only at annual pre-tax cash flow relative to the cash you invested.

Does cash-on-cash return include appreciation?

No. It measures annual cash flow only. If a property appreciates in value, that gain is not reflected in the cash-on-cash figure — you’d capture it through total ROI or at sale.

What counts as “cash invested”?

The actual out-of-pocket cash to acquire and ready the property: the down payment, closing costs, and any upfront rehab or make-ready spend. The financed portion of the purchase price is not part of cash invested — that’s what the mortgage covers.

Is cash-on-cash return calculated before or after taxes?

The standard formula uses pre-tax cash flow. Your after-tax result will differ depending on depreciation, deductions, and your personal tax rate. [Cash-on-Cash Return (COCR) in Real Estate, JPMorgan Chase, accessed July 3, 2026]

Can two investors get different cash-on-cash returns on the same property?

Yes. Because the metric includes financing, differences in down payment size, interest rate, and loan term change both the cash flow and the cash invested — so the same property can produce different cash-on-cash returns for different buyers.

Is a higher cash-on-cash return always better?

Not necessarily. A higher figure often comes from higher leverage or higher-risk assumptions. Look at the return alongside the risk you’re taking and what the metric leaves out (appreciation, principal paydown, vacancy, taxes).
