Cash on cash return is your annual pre-tax cash flow divided by the actual cash you put into a rental property, shown as a percentage. If you invest $70,000 and the property sends you $7,000 a year after every bill and the mortgage, your cash on cash return is 10%. It tells you how hard your own money is working, which is why investors use it to screen deals before they run anything deeper.
Below you'll find the formula, a full worked example with real arithmetic, a comparison with cap rate and ROI, the benchmarks investors use, and the mistakes that make a deal look better than it is.
TL;DR
- Cash on cash return = annual pre-tax cash flow ÷ total cash invested. It measures yield on your own money, after debt service.
- Many investors treat 8% to 12% as a typical range, but the right target depends on your market, your financing and your goals.
- Cap rate ignores the mortgage. Cash on cash includes it, so two buyers of the same house can get different numbers.
- The most common error is leaving out costs: vacancy, repairs, turnover and management. Leave them out and the return is fiction.
- Treat it as a quick screen, not a verdict. It ignores appreciation, principal paydown and taxes.

What cash on cash return actually measures
Cash on cash return compares a rental's annual pre-tax cash flow to the equity you contributed. It answers one question: for every dollar I wrote a check for, how many cents came back this year as spendable cash?
Three features define it:
- It is levered. The mortgage payment is subtracted, so financing terms change the answer.
- It is pre-tax. Income tax, depreciation and your personal bracket are not in the formula.
- It is a one-year snapshot. It does not count appreciation or the equity you build as the loan balance falls.
That is why ROI and cash on cash differ: ROI looks at the total return on the whole investment, including appreciation over time, while cash on cash looks only at the annual cash generated against the cash invested.
The formula, step by step
Cash on cash return = annual pre-tax cash flow ÷ total cash invested × 100
1. Total cash invested
Add every dollar that left your account to acquire and ready the property:
- Down payment
- Closing costs and lender fees
- Immediate repairs or upgrades
- Any reserves you fund on day one
Do not include the loan amount. That is the whole point of a levered metric.
2. Annual pre-tax cash flow
Start with potential rent for the year, then subtract:
- Vacancy and credit loss
- Property taxes and insurance
- Maintenance and repairs
- Management fees
- Any HOA dues or utilities you pay
- Mortgage payments (principal and interest)
What remains is cash flow. Divide by step 1.
A worked example
Here is a hypothetical single-family rental. The numbers are illustrative, not a market quote.
| Input | Amount |
|---|---|
| Purchase price | $250,000 |
| Down payment (25%) | $62,500 |
| Closing costs | $5,000 |
| Initial repairs | $3,000 |
| Total cash invested | $70,500 |
| Loan | $187,500 at 6.5%, 30 years |
| Monthly rent | $2,300 |
Now the year:
| Line | Annual |
|---|---|
| Gross rent (12 × $2,300) | $27,600 |
| Vacancy at 5% | −$1,380 |
| Rent collected | $26,220 |
| Management at 10% of collected rent | −$2,622 |
| Property taxes | −$2,800 |
| Insurance | −$1,500 |
| Maintenance and repairs | −$2,200 |
| Net operating income | $17,098 |
| Mortgage payments (about $1,185 a month) | −$14,221 |
| Pre-tax cash flow | $2,877 |
Cash on cash return: $2,877 ÷ $70,500 = about 4.1%.
That is below the range many investors target. Now see what a modest change does. If the same house rents for $2,500, gross rent is $30,000, collected rent is $28,500, and net operating income rises to $19,150. Cash flow becomes $4,929, and the return becomes about 7.0%. A $200 difference in monthly rent nearly doubled the yield on your cash. That is why pricing the rent correctly matters as much as negotiating the purchase; our guide to pricing Atlanta rentals within 3 to 5% and factoring in concessions covers it.
Cash on cash vs. cap rate
Cap rate is net operating income divided by price. In the first example that is $17,098 ÷ $250,000, or about 6.8%. It says nothing about how you paid.
The two figures are equivalent only when you buy with all cash. With a loan, cash on cash is typically lower because it absorbs debt service, while cap rate ignores debt entirely.
Run the all-cash version of our example: $250,000 plus $8,000 of closing and repairs is $258,000 invested. Cash flow equals net operating income, $17,098, so the return is about 6.6%. The financed version earned only 4.1%. When the interest rate on the loan is close to or above the property's cap rate, borrowing does not boost your return. It lowers it. When the cap rate comfortably beats your loan rate, leverage works in your favor.
| Cap rate | Cash on cash return | |
|---|---|---|
| Uses mortgage payments | No | Yes |
| Denominator | Purchase price | Cash you invested |
| Best for | Comparing properties and markets | Judging your own deal and financing |
| Changes with your loan | No | Yes |
Use cap rate to compare properties, and cash on cash to decide whether a specific purchase, with your specific loan, fits your goals. For a side-by-side treatment of the two metrics on financed properties, that explainer is worth a read. For local context, see our look at Atlanta cap rates for investors.
Why two investors get different numbers on the same house
Because it is a levered metric, two buyers of the identical property can post different returns based solely on down payment, interest rate and loan structure. One puts 20% down at a higher rate. Another puts 35% down and locks a lower rate. Same rent, same taxes, different yield.
This is also why cash on cash suits personal decisions. It shows investment efficiency for you, not the property's inherent value. If you are exploring creative structures, read how to buy a rental property with no money down first, and note one quirk: when almost no cash goes in, the percentage can look enormous while the actual dollars are thin and the risk is high.
What is a good cash on cash return?
A commonly cited benchmark is 8% to 12%, though it moves with market conditions, economic sentiment and strategy. Read the common questions this way:
- Is 10% good? It sits inside the typical range, so for many investors it is solid, provided your expense estimates are honest.
- Is 20% good? Possibly, but treat it as a prompt to check assumptions. Very high figures often come from underestimated repairs, optimistic rent, a thin down payment, or a property in an area with higher risk.
- Is 4% bad? Not automatically. An investor in a high-appreciation area may accept a low yield for equity growth. An investor who needs monthly income may not.
The right target depends on what you want the property to do: pay you now, build equity, or both. Set the number before you shop, not after you fall for a house.
The costs that quietly inflate your return
Most overstated returns come from incomplete expenses. A few to include every time.
Vacancy and turnover
A unit is not rented 12 months a year forever. Between tenants you pay the mortgage, taxes and utilities with no income, plus cleaning, paint and repairs. We broke down what a rental turnover really costs in Atlanta so you can build it into your budget instead of discovering it.
Costs you don't write checks for
Owners often miss what they absorb in other ways. Research on rental economics notes that cash expenses can be less than half of total operating costs in some markets, with the rest covered by tenants or by owners doing their own work. If you do repairs yourself, your time has a value. Ignoring these hidden costs makes your perceived return look better than it is.
Management
Self-managing feels free, but it is not. Even if you never pay a manager, price the hours. If you do pay one, include the fee. Our published management fee is 10% per month, with a $250 one-off onboarding fee and a $500 one-off lease renewal fee. The optional Owner Benefit Package (OBP™) is $40 per month per unit. Put those lines into your model so the return you calculate is the return you get.
Bookkeeping
Many small landlords judge profitability by whether money is left in the checking account after the mortgage. A HUD research report on urban landlords describes this checkbook test as common. It hides the truth: it ignores reserves, deferred repairs and rising costs. Clean monthly reporting fixes it. See what owner statements tell you about your cash.
What cash on cash leaves out
Analysts describe it as a napkin test for initial screening. It gives a fast read on annual yield but ignores:
- Appreciation. A property that grows in value can beat a higher-yield one over ten years.
- Principal paydown. Part of each mortgage payment builds your equity but is counted as an expense here.
- Taxes. The formula is pre-tax. Depreciation can defer taxes, and cash flow is not the same as taxable income. IRS Publication 527 covers residential rental property and the records you need to keep. For Georgia specifics, see our guide to Georgia landlord taxes, and talk to a CPA about your own situation.
- Risk and time. A 9% return with a bad tenant and a 7% return with a stable one are not equal.
Lenders look past it too. Freddie Mac's multifamily guide uses debt service coverage and actual operating performance rather than projections when sizing loans. Borrow that discipline: base your own numbers on real rents and real expenses, not hopes.
Perspective: what we see from the management side
We manage rental homes for investors in Atlanta and the surrounding area, so we see the gap between the spreadsheet and the owner statement every month. The gap is almost never the purchase price. It is the line items that were never in the model: a vacancy that ran six weeks longer than planned, a turnover that cost more than a month's rent, a lease renewal that was skipped and left the unit month-to-month.
Our advice is simple. Model with a vacancy allowance, a real repair reserve and a management line, then check the result against your target. If the deal only works with zero vacancy and no management fee, it does not work. And once you own, track the actual return every quarter, because the number you underwrote is a forecast and the number on your statements is the truth.
The good news is that the levers are controllable: price the rent correctly, shorten vacancy with sharp marketing, screen tenants carefully, renew good ones. Those moves lift cash flow without changing what you paid for the house.

How to improve your cash on cash return
There are two sides to the fraction: raise cash flow, or lower the cash you tied up.
- Raise rent where the market supports it. Our example showed a $200 monthly increase lifting the return from about 4.1% to 7.0%.
- Cut vacancy. A strong listing and fast showings matter. Our rental listing description ideas help.
- Reduce turnover. Renew good tenants. A renewal is cheaper than a vacancy and a make-ready.
- Control repairs. Coordinated maintenance with vetted vendors usually costs less than emergency calls.
- Refinance when it pencils. If rates fall below your cap rate, a lower payment lifts cash flow. Count the refinance costs as cash invested.
- Recover rent owed. Unpaid rent is lost return. Have a plan, such as our court-ready rent debt collection templates.
A quick checklist before you trust the number
- Did you use actual or comparable rents, not asking rents?
- Did you include vacancy, repairs, taxes, insurance and management?
- Did you count all closing costs and initial repairs as cash invested?
- Does the result still work if rent drops 5% or repairs double?
- Does it clear your target and your lender's coverage requirements?

FAQ
Is a 20% cash on cash return good?
It can be, but check how you got there. Typical benchmarks cluster around 8% to 12%, so 20% usually means high risk, a very small cash investment, or assumptions that are too optimistic. Rebuild the numbers with realistic vacancy and repair costs before you celebrate.
What is the difference between ROI and cash on cash return?
Cash on cash return looks at one year of pre-tax cash flow against the cash you invested. ROI considers the total return, including appreciation and equity gains over time. Use cash on cash to screen income, and ROI to judge the full picture.
Is cash on cash return the same as cap rate?
Only in an all-cash purchase. Cap rate uses net operating income and price, ignoring debt. Cash on cash subtracts mortgage payments and divides by your cash invested, so financing changes it.
Does cash on cash return include taxes?
No. It is calculated on pre-tax cash flow. Depreciation and other tax effects are separate, so ask a CPA how your rental will be taxed.
