Cash-on-cash return is the annual pre-tax cash flow a property produces divided by the total cash the investor put into it. It measures the yield on your own money, not on the full purchase price, which makes it the standard way to judge a financed rental or commercial property. A 7% cash-on-cash return means that every $100 of cash invested returned $7 of spendable cash flow that year, before income taxes. Some investors call it the cash yield.

The Cash-on-Cash Return Formula

The basic formula is:

Cash-on-cash return = Annual pre-tax cash flow ÷ Total cash invested

Annual pre-tax cash flow is built from the property’s income and costs:

Annual pre-tax cash flow = (Gross scheduled rent + Other income) − (Vacancy + Operating expenses + Annual mortgage payments)

• Gross scheduled rent: the rent the property would collect if fully leased for the year.
• Other income: parking, laundry, storage, fees or similar revenue.
• Vacancy: rent lost to empty units and nonpayment.
• Operating expenses: property taxes, insurance, maintenance, utilities paid by the owner, management.
• Annual mortgage payments: total debt service, meaning both interest and principal.

Total cash invested covers everything that came out of the investor’s pocket to acquire the property and make it rentable: the down payment, closing costs, loan fees and upfront renovation. Borrowed money is not included, which is the whole point of the metric.

Worked Example: A Financed Rental

In a hypothetical example, an investor buys a $300,000 rental with a 25% down payment.

Cash invested

• Down payment: $75,000
• Closing costs: $9,000
• Upfront repairs: $6,000
• Total cash invested: $90,000

Annual cash flow

• Gross scheduled rent ($2,700 × 12): $32,400
• Other income: $600
• Vacancy (assumed 5% of rent): −$1,620
• Operating expenses: −$9,000
• Mortgage payments (assumed debt service on the $225,000 loan): −$16,800
• Annual pre-tax cash flow: $5,580

Cash-on-cash return = $5,580 ÷ $90,000 = 6.2%

The same property bought with all cash

Without a loan, there is no debt service, but the investor puts in $300,000 plus $15,000 of closing costs and repairs, or $315,000.

• Cash flow: $33,000 − $1,620 − $9,000 = $22,380
• Cash-on-cash return: $22,380 ÷ $315,000 = 7.1%

In this example, borrowing lowered the cash-on-cash return, because the loan’s annual payments are expensive relative to the property’s income. Leverage raises cash-on-cash return only when the property earns more on each financed dollar than the loan costs per dollar borrowed.

How Investors Use It

Cash-on-cash return answers a practical question: how much cash will this deal put in my pocket each year for the money I commit? Investors use it to:

• Screen deals. Comparing properties with different prices and loan terms on one cash basis.
• Compare financing options. A larger down payment, a different interest rate or a longer amortization each change the result, as the example shows.
• Forecast distributions. In syndications and partnerships, sponsors often project a cash-on-cash return to describe expected yearly payouts. That projection is a target, not a promised payment like a bond coupon.
• Track performance. Recalculating with actual rent and expenses each year shows whether the property is meeting the original plan.

What counts as a good cash-on-cash return?

There is no universal benchmark. The acceptable figure depends on interest rates, the market, the property’s condition, expected appreciation and what the cash could earn elsewhere. A low return can be acceptable where strong price growth is expected, while a high one may reflect a riskier property or neighborhood.

Cash-on-Cash Return vs. Other Metrics

Cash-on-cash return vs. ROI

The terms are sometimes used interchangeably, but they diverge once debt is involved. ROI generally measures total return, which can include appreciation, principal paydown and sale proceeds, and it is often computed on the full investment rather than just the investor’s cash. Cash-on-cash return isolates the annual cash generated by the cash actually invested. ROI definitions vary between users, so always confirm what a quoted ROI includes.

Cash-on-cash return vs. cap rate

The capitalization rate is net operating income divided by the property’s price or value. It ignores financing entirely, so it describes the property itself, while cash-on-cash return describes the investor’s specific deal, including the loan and acquisition costs. The two differ even for an all-cash purchase. In the example, the cap rate is roughly $22,380 ÷ $300,000, or 7.5%. Cash-on-cash return is 7.1% because its denominator also includes closing costs and upfront repairs.

Cash-on-cash return vs. IRR and equity multiple

Internal rate of return (IRR) accounts for all cash flows over the full holding period, including the eventual sale, and weights them by timing. The equity multiple (also called MOIC) divides total cash returned by total cash invested over the whole hold, without regard to time. Cash-on-cash return is a single-year snapshot. A deal can have a modest yearly cash-on-cash return and a strong IRR if most of the profit comes at sale.

Some analysts apply the cash-on-cash formula to a full hold, including sale proceeds. For example, an investor who spends $135,000 in total cash (down payment, costs and loan payments) and nets $205,000 after selling and repaying the loan would show ($205,000 − $135,000) ÷ $135,000 = 51.9%. That is a total return on cash, not an annual yield, so label it clearly.

Limitations

• Ignores appreciation. Gains in property value do not appear until sale.
• Treats principal paydown as a cost. The principal portion of each mortgage payment builds equity, yet it reduces cash flow in the formula, which understates the investor’s economic return.
• Pre-tax only. Depreciation and other tax effects can make after-tax results differ meaningfully.
• One year at a time. It doesn’t reflect rent growth, rising expenses, refinancing or the time value of money.
• Only as good as the inputs. Optimistic vacancy, expense or repair assumptions inflate the result.
• Sensitive to leverage. A small cash investment can produce a high percentage while carrying greater risk if rents fall and the mortgage still has to be paid.
• Ignores inflation. A fixed cash yield loses purchasing power over time.

The Bottom Line

Rental and commercial property investors who use financing can rely on cash-on-cash return to screen deals, compare loan options and track yearly cash flow. It is a single-year, pre-tax snapshot that leaves out appreciation, principal paydown and tax effects, so investors should pair it with cap rate, IRR or equity multiple and test their vacancy and expense assumptions.
