Cash-on-Cash Return: How to Calculate It for Rental Property

A rental listing can look great on rent alone, but rent doesn't tell you what your own cash is earning. This guide walks through the cash-on-cash return formula, a worked example, and the parts of the deal it doesn't measure.

Why the rent number on the listing can mislead you

A property that rents for a healthy amount can still be a weak investment once you account for the mortgage payment, taxes, insurance, and the cash you had to put down to buy it in the first place. Two buyers can purchase the same duplex and end up with very different results, because one paid cash and the other financed most of the price. Rent alone doesn't separate those outcomes.

Cash-on-cash return is built to answer a narrower, more useful question: for every dollar of your own cash tied up in this property, how much cash comes back to you each year. This article walks through the formula, a step-by-step example, what counts as "cash invested," and where the number stops being useful.

The formula: annual cash flow divided by the cash you actually put in

Cash-on-cash return is calculated as: annual pre-tax cash flow divided by total cash invested, expressed as a percentage.

Annual pre-tax cash flow is the rent collected over a year, minus operating expenses (property taxes, insurance, maintenance, property management, vacancy allowance) and minus the full mortgage payment (principal and interest). It's the cash left in your pocket before income taxes are applied.

Total cash invested is the money you personally put in, not the purchase price. That usually means the down payment, closing costs, and any upfront repairs or reserve funds, all added together.

A step-by-step example using round numbers

Say a rental property costs $200,000. A buyer puts 25 percent down ($50,000), pays $6,000 in closing costs, and spends $4,000 fixing up the unit before renting it out. Total cash invested is $60,000.

The property brings in $24,000 a year in rent. After property taxes, insurance, maintenance, a vacancy allowance, and property management, operating expenses run $9,000 a year. The mortgage payment on the remaining $150,000 loan totals $10,000 a year in principal and interest. That leaves annual pre-tax cash flow of $24,000 minus $9,000 minus $10,000, or $5,000.

Cash-on-cash return is $5,000 divided by $60,000, which comes out to about 8.3 percent. That's the return on the cash the buyer actually risked, not on the full $200,000 price of the property.

What counts as 'cash invested' (and what people leave out)

The most common mistake in this calculation is undercounting the cash invested. Closing costs, loan origination fees, immediate repair costs, and any reserve fund set aside for future vacancies or repairs all belong in that number, even though they don't show up on the purchase price.

Financing terms change this figure a lot. Investment properties typically require a larger down payment than a primary residence; both Freddie Mac and Fannie Mae set higher minimum down payment standards for non-owner-occupied properties in the loans they back. A bigger down payment means more cash invested and, all else equal, a lower cash-on-cash return, even though the property itself hasn't changed.

Before running these numbers on a specific property, a look at its overall condition helps you avoid underestimating the repair side of the equation. The free home report can give you a starting picture of a property's condition before you commit cash to it.

Five things this one number cannot tell you

Cash-on-cash return is a snapshot of cash flow in a single year, so it has real limits worth knowing before anyone leans on it too hard.

• It ignores appreciation. A property with break-even cash flow can still build wealth if the property value rises, and this formula doesn't capture that.

• It ignores principal paydown. Part of every mortgage payment reduces what you owe and builds equity, but the formula treats the whole payment as an expense.

• It ignores taxes on the income itself. Rental income is taxable, and expenses like depreciation can reduce that tax bill in ways this formula doesn't reflect; the IRS explains what counts as deductible rental expense.

• It assumes steady rent and occupancy. A vacancy stretch or a rent cut changes the actual number without changing the formula.

• It says nothing about landlord obligations. Owning and renting property comes with legal responsibilities, including fair housing rules that HUD oversees, and those responsibilities don't show up in a cash flow spreadsheet.

What to check alongside cash-on-cash return before you decide

Cash-on-cash return works best next to other numbers, not alone. A cap rate (return based on the purchase price with no financing) helps you compare properties independent of how each buyer financed the deal. A total return figure that adds back appreciation and principal paydown gives a fuller picture over several years.

Insurance costs are a real line item that swings the cash flow side of the math, and landlord policies often cost more than a standard homeowner policy; the Insurance Information Institute has background on how landlord coverage differs from a typical policy. Ongoing repair costs matter just as much, and the honest home warranty guide walks through when a warranty plan actually offsets those costs and when it doesn't.

If you already own the property and are weighing whether to keep renting it out or sell, the sell-or-rent calculator puts cash-on-cash return next to the sale-proceeds side of that decision. None of these tools or numbers replace a professional review of the property itself or its financing. This article is not professional contractor, insurance, or engineering advice, and a lender, tax preparer, or licensed inspector should weigh in on the specifics of any deal.

Questions people ask

What counts as a good cash-on-cash return for a rental property?
There's no official benchmark number, because it depends on the market, the financing, and what return an investor could get elsewhere with that same cash. Investors generally compare the figure against other properties they're considering and against their own required return, rather than a fixed rule of thumb.

Is cash-on-cash return the same thing as cap rate?
No. Cap rate measures return based on the purchase price as if the property were bought with all cash, with no financing involved. Cash-on-cash return measures return on the actual cash invested, so financing choices like the down payment size directly change the result.

Does cash-on-cash return include the equity I build by paying down the mortgage?
No. The standard formula only counts the cash that actually leaves or enters your pocket each year, so the portion of each mortgage payment that reduces the loan balance is treated as an expense, not a benefit. Some investors track a separate total return figure that adds principal paydown and appreciation back in.

Do vacancy and property management costs belong in the calculation?
Yes. Any cost that actually reduces the cash you collect, including a vacancy allowance and management fees, belongs in the operating expense side of the formula. Leaving them out overstates the annual cash flow and makes the return look better than it will actually be.
