Cash on cash return (CoC) measures your annual pre-tax cash flow as a percentage of the total cash you invested in a property. If you invested $100,000 in a rental property and it generates $9,000 in annual pre-tax cash flow after all expenses including the mortgage, your cash on cash return is 9%. The industry benchmark for a solid CoC return is 8% to 12% for most residential rental properties.
Of all the metrics used to evaluate rental properties, cash on cash return is the one that most directly answers the question investors actually care about: how hard is my money working for me right now?
It does not care about future appreciation. It does not measure the return on the whole property value. It measures the return on the specific dollars you personally put into the deal, in the current year, after the mortgage (liability) is paid. That focus makes it one of the most useful and most misunderstood metrics in real estate investing.
This guide explains the formula, walks through complete worked examples, explains what a good CoC return looks like across different property types and markets, compares it to cap rate and ROI, and covers the most common mistakes investors make when calculating it.
Cash on Cash Return = Annual Pre-Tax Cash Flow
/ Total Cash Invested
× 100
Two inputs. One output.
Annual pre-tax cash flow is the money left over after you have collected all rental income and paid all expenses including your mortgage payments. It is calculated before income taxes.
Annual Pre-Tax Cash Flow = Gross Rental Income
- Operating Expenses
- Annual Debt Service (mortgage payments)
Total cash invested is every dollar you personally put into the deal to acquire and prepare the property for rental. This is not the purchase price. It is your actual cash outlay.
Total Cash Invested = Down Payment
+ Closing Costs
+ Initial Repairs and Renovations
+ Any Other Upfront Cash Expenses
Optional — any upfront repairs or improvements
Typical: 5–10%
Parking, laundry, storage, etc.
Of gross monthly rent
Optional — leave 0 to exclude
Set aside for future large repairs
Principal & interest, plus escrow if included
You need $506/mo more rent than your current $2,000/mo to hit 8% CoC.

A single-family rental home in Phoenix, Arizona. Purchase price $320,000, financed with 25% down.
Step 1: Calculate total cash invested
| Item | Amount |
|---|---|
| Down payment (25%) | $80,000 |
| Closing costs | $6,400 |
| Initial repairs | $4,500 |
| Total cash invested | $90,900 |
Step 2: Calculate annual pre-tax cash flow
Monthly rent: $2,200. Annual gross rent: $26,400.
| Expense | Annual Amount |
|---|---|
| Property taxes | $3,800 |
| Insurance | $1,600 |
| Property management (10%) | $2,640 |
| Maintenance and repairs | $2,400 |
| Vacancy allowance (5%) | $1,320 |
| Total operating expenses | $11,760 |
This property is cashflow-negative at these inputs. The CoC return is negative, meaning you are subsidizing the property each month.
Adjusting the example to a property with stronger rent or lower financing:
If the same property rented for $2,600/month and the investor had put 30% down (lower loan, lower debt service of approximately $17,040/year):
Total cash invested: $96,000 + $6,400 + $4,500 = $106,900
CoC = ($1,680 / $106,900) × 100 = 1.6%
Still low. This illustrates a real challenge in high-cost markets at current interest rates: even strong rents often produce modest CoC returns when debt service is expensive.
A better CoC example in a secondary market:
A duplex in Memphis. Purchase price $220,000, 25% down. Each unit rents for $1,100/month.
| Item | Amount |
|---|---|
| Down payment (25%) | $55,000 |
| Closing costs | $4,400 |
| Initial repairs | $6,000 |
| Total cash invested | $65,400 |
CoC = ($2,640 / $65,400) × 100 = 4.0%
Better, but still below the 8% benchmark. Getting to 8% or above typically requires a combination of below-market purchase price, strong rents relative to the market, or lower leverage than a standard 75% LTV purchase allows.
An 8% to 12% cash on cash return is generally considered good, though individual expectations and market dynamics play crucial roles in determining what is ideal for each investor.
That benchmark comes from comparing CoC against alternative uses of the same capital. If a high-yield savings account pays 4.5% and Treasury bonds pay around 4.5% to 5% with essentially no risk or management effort, a rental property needs to meaningfully exceed those rates to justify the illiquidity, management burden, and risk. A CoC of 8% to 12% clears that hurdle. Below 6%, the case for taking on landlord responsibilities becomes harder to justify on cash flow alone.
By market and property type:
Properties in high-demand urban areas might deliver lower CoC of 5% to 7% but offer greater appreciation potential and lower risk. Properties in less-established markets might offer higher returns of 10% to 15% but come with increased risk and uncertainty.
The interest rate effect:
Cash on cash return is sensitive to interest rates in a way that cap rate is not. When mortgage rates move from 4% to 7%, debt service on the same loan increases substantially, directly reducing pre-tax cash flow and therefore CoC. Many properties that showed 8% CoC returns in 2020 and 2021 at low interest rates showed 2% to 4% CoC returns at 2023 to 2024 interest rate levels with the same rents and purchase prices. Always calculate CoC at current rates, not historical ones.
These two metrics are related but measure different things. Understanding the difference is essential for using either one correctly.
The cap rate measures the expected rate of return on an investment property. Cash on cash return measures the annual pre-tax cash flow received per dollar of equity invested, determined on a post-financing basis.
| Cash on Cash Return | Cap Rate | |
|---|---|---|
| Includes mortgage payments | Yes | No |
| Based on | Your cash invested | Full property value |
| Affected by financing | Yes | No |
| Best for | Comparing deals with different down payments | Comparing properties independent of financing |
| Measures | Your personal return on invested capital | The property's income return as an asset |
The key insight: two investors can buy the same property at the same price and arrive at the same cap rate but completely different CoC returns, depending on how much they put down and at what interest rate.
A practical example:
Same property, $400,000 purchase price, $24,000 NOI, 6% cap rate.
Investor A puts 20% down ($80,000). Annual debt service on $320,000 at 7%: approximately $25,600. Pre-tax cash flow: negative $1,600. CoC: negative.
Investor B pays all cash. No debt service. Pre-tax cash flow: $24,000. CoC: 6% (equals the cap rate, as expected when there is no leverage).
Investor C puts 40% down ($160,000). Annual debt service on $240,000 at 7%: approximately $19,200. Pre-tax cash flow: $4,800. CoC: $4,800 / $160,000 = 3%.
The cap rate is 6% for all three. The CoC return ranges from negative to 6% depending entirely on the financing structure.
Cash-on-cash return focuses solely on annual cash flow relative to your initial cash investment, while return on investment looks at the property's overall performance, which includes long-term factors like appreciation and paying down loan debt.
ROI is a broader, longer-term metric. It captures the total return over a holding period, including:
A property with a modest CoC return of 4% might generate a 15% to 20% total ROI over ten years once appreciation and equity growth are included. This is exactly why many investors in gateway cities accept low CoC returns: they are betting on the appreciation and equity components of total return to compensate.
Use CoC when you want to understand current cash performance. Use ROI when you want to understand total wealth creation over a holding period.
Getting the denominator right is where many investors make mistakes. Total cash invested is not just your down payment.
Include:
Do not include:
Leaving closing costs and renovation costs out of total cash invested makes CoC look better than it is. A $90,000 down payment with $12,000 in closing costs and repairs is a $102,000 cash investment, not a $90,000 one. The difference can shift your CoC meaningfully.
Cash-on-cash return does not account for property appreciation, tax benefits, or equity buildup from mortgage principal payments. A property with a 6% CoC that appreciates 5% annually builds wealth differently than a property with a 10% CoC in a flat market.
Other limitations worth knowing:
It is a single-year snapshot. CoC measures current year performance. It does not show you how returns change as rents grow, the loan pays down, and interest deductions shift over time. A property that looks modest at year one CoC can be significantly stronger by year five as rents increase and the same debt service covers a smaller share of income.
Pre-tax means before your tax situation. CoC is calculated before income tax. Depreciation deductions, mortgage interest deductions, and your marginal tax rate all affect your actual after-tax return differently depending on your specific situation.
It does not capture refinancing opportunities. If the property appreciates significantly and you refinance at a lower LTV, pulling out equity tax-free, that changes your effective cash-on-cash return on the remaining invested capital in ways the initial formula does not capture.
Calm Sea's investment property tracker calculates your cashflow and equity position year by year, rolling each property into your total net worth view alongside your other assets. Rather than recalculating CoC manually every time your rents, expenses, or financing changes, Calm Sea keeps the numbers current as you update inputs.
It also shows you how your investment property performs as part of your complete financial picture. A property with a 5% CoC sitting alongside a paid-off share portfolio and growing superannuation balance tells a different story than the same property sitting as your only asset. Seeing the full context is what drives better decisions.

What is cash on cash return in real estate?
Cash on cash return is your annual pre-tax cash flow divided by your total cash invested in a property, expressed as a percentage. It measures how much cash income you earn each year relative to the dollars you personally put into the deal, after paying the mortgage.
What is a good cash on cash return?
8% to 12% is generally considered a solid range for cash on cash return in real estate, suggesting a healthy balance between risk and reward. Below 6% is often considered marginal for the effort and risk involved. Above 12% typically signals either a value-add opportunity or a higher-risk market.
What is the difference between cash on cash return and cap rate?
Cap rate measures a property's income return before financing costs, making it useful for comparing properties independent of how they are financed. Cash on cash return includes mortgage payments and measures return on your specific cash investment. The same property can have the same cap rate for two investors but very different CoC returns depending on their down payment and interest rate.
Does cash on cash return include appreciation?
No. CoC measures only annual cash flow relative to your initial cash investment. Property appreciation, equity buildup from loan paydown, and tax benefits are not included. Use ROI or IRR to capture total return over a holding period.
Why is my cash on cash return negative?
A negative CoC means your annual expenses including the mortgage exceed your rental income. You are subsidizing the property each month. This is not automatically a bad investment. Many investors accept negative cash flow in high-appreciation markets, but it means the investment depends on future value growth rather than current income to justify holding.
