Cash on Cash Return Calculator: The Complete Real Estate Investor’s Guide

What Is Cash on Cash Return?

Cash on cash return (CoC) is the most widely used metric for evaluating rental property performance. It measures how much annual cash income you receive relative to the cash you actually put into the deal — your down payment, closing costs, and any upfront repair costs.

The formula is straightforward:

Cash on Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100

Pre-tax cash flow is the money left over after collecting rent, paying all operating expenses, and making your monthly mortgage payment. Total cash invested is every dollar you put in out of pocket to acquire and prepare the property.

According to a 2024 BiggerPockets investor survey, cash on cash return is the primary screening metric for 67% of active rental property investors, ahead of cap rate (18%) and gross rent multiplier (15%). It’s popular because it reflects the reality of leveraged investing: most buyers use a mortgage, and the mortgage payment directly determines how much cash flow remains.

The Cash on Cash Return Formula: Step by Step

To calculate CoC correctly, you need two numbers:

Step 1: Calculate Annual Pre-Tax Cash Flow

Start with gross annual rent. Subtract operating expenses: property taxes, insurance, property management fees (typically 8–10% of gross rent), maintenance and repairs (budget 1% of property value annually), vacancy allowance (typically 5–8%), and utilities you cover as landlord.

That gives you Net Operating Income (NOI). Then subtract your annual mortgage payments (principal + interest). The result is your annual pre-tax cash flow.

Step 2: Calculate Total Cash Invested

Add up everything you paid out of pocket: down payment, closing costs (typically 2–5% of purchase price), inspection fees, upfront repairs, and any capital expenditures to prepare the property for rent.

Step 3: Divide and Multiply

Divide annual pre-tax cash flow by total cash invested. Multiply by 100 to get the percentage. Done.

Step-by-Step CoC Calculation Example

Let’s walk through a real rental property scenario.

The loan amount is $210,000 at 7% for 30 years. Monthly mortgage payment: approximately $1,397. Annual debt service: $16,764.

At 7% financing, this deal produces negative cash flow of about $152/month. The cash on cash return is –2.3% — not a good deal at current rates.

Now run the same numbers with a 5% interest rate (as many investors locked in during 2020–2021):

Even at 5%, cash flow on this property is thin. To hit a 8% CoC target on $80,000 invested, you’d need $6,400 in annual pre-tax cash flow — meaning NOI would need to be around $7,600+ per year more than the debt service allows at current rates. This illustrates why many investors struggled to pencil deals in 2024–2025.

What Is a Good Cash on Cash Return?

There’s no universal benchmark — it depends heavily on market, property type, and what alternatives exist. But here are the general thresholds most experienced investors use:

According to CBRE’s 2025 US Multifamily Report, average cap rates for Class B multifamily properties are running 5.5–6.5% nationally. Actual CoC returns depend on leverage used, but most investors surveyed by BiggerPockets in 2024 reported average CoC returns of 6.2%on their most recent acquisitions — down from 9.1% in 2021.

The NAR 2024 Investment and Vacation Home Buyers Survey found that 38% of investment property buyers cited cash flow as their primary motivation, and most targeted at least 8% CoC before purchasing.

Cash on Cash vs Cap Rate: Key Differences

These two metrics are often confused. They measure different things and serve different purposes.

Cap rate is a property-level metric. It tells you the property’s yield as if no financing existed. This makes it useful for comparing properties across markets, because two investors with different down payments would see the same cap rate on the same deal.

Cash on cash is an investor-level metric. It changes based on how much you put down, what interest rate you get, and how you structure the financing. Two investors buying the same property with different loans will see very different CoC returns.

When Cap Rate > Cost of Debt: Positive Leverage

When cap rate exceeds your mortgage rate, leverage works in your favor. You’re borrowing money at a lower rate than the property earns, so CoC return exceeds cap rate. A property with a 7% cap rate financed at 5% will produce a CoC return higher than 7%.

When Cap Rate < Cost of Debt: Negative Leverage

When cap rate falls below your mortgage rate, leverage works against you. Every dollar borrowed reduces your cash flow more than it would generate. This is the situation many investors found themselves in during 2023–2025, when rates rose above cap rates in most major markets.

5 Ways Leverage Affects Cash on Cash Return

Leverage is the most powerful variable in the CoC equation. Here’s how different financing scenarios affect the same property:

Assume a $300,000 property with $24,000 NOI (8% cap rate).

Notice: at a 7% rate, even with 25% down, leverage neither helps nor hurts — CoC equals cap rate. At 5%, leverage amplifies returns significantly. At 8%, leverage destroys cash flow. This table makes clear why interest rates are the central variable in rental property investing right now.

A 2024 analysis by Roofstock found that a 1% increase in mortgage rate reduces average CoC return by approximately 2.1 percentage points on a typical single-family rental financed at 75% LTV.

CoC Return: What It Misses

Cash on cash is a useful screening tool, but it’s incomplete. Here’s what it doesn’t capture:

• Appreciation: Property values rising 3–5% annually can dwarf cash flow in high-cost markets. Many coastal investors accept low CoC because appreciation expectations are high.
• Equity paydown: Each mortgage payment reduces your loan balance. Over 30 years, this equity buildup can be substantial. CoC ignores it entirely.
• Tax benefits: Depreciation deductions can shelter significant rental income from taxes. A property with a 6% CoC might produce after-tax returns equivalent to an 8–9% CoC once depreciation is factored in.
• Forced appreciation: Value-add investors who renovate and raise rents can dramatically improve CoC over time. The entry-year CoC is just a starting point.

For a more complete analysis, investors use Internal Rate of Return (IRR) over a projected 5–10 year hold period, which incorporates cash flow, equity growth, appreciation, and resale proceeds.

Frequently Asked Questions

What is cash on cash return in real estate?

Cash on cash return (CoC) measures the annual pre-tax cash flow you receive divided by the total cash you invested, expressed as a percentage. It tells you how much cash your cash is earning each year — ignoring appreciation, equity paydown, and tax benefits. Formula: CoC = Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100.

What is a good cash on cash return for rental property?

A cash on cash return of 8–12% is generally considered good in most US markets. Returns above 12% are excellent, particularly in higher-risk or tertiary markets. Below 6% may not justify the illiquidity of real estate when compared to alternatives like REITs or bonds. In expensive coastal markets (NYC, San Francisco), even 4–6% CoC can be acceptable if strong appreciation is expected.

What is the difference between cash on cash return and cap rate?

Cap rate ignores financing — it divides Net Operating Income (NOI) by total property value, as if you paid all cash. Cash on cash return accounts for your actual mortgage payments and measures return on just the cash you put in (down payment + closing costs). The same property can have a 7% cap rate but a 14% cash on cash return when using favorable leverage with a low interest rate.

Does cash on cash return include appreciation?

No. Cash on cash return is a pure cash flow metric — it only measures the cash you receive each year relative to the cash you put in. It does not include property appreciation, equity buildup from mortgage paydown, or tax benefits like depreciation deductions. For a more complete picture, investors use Total Return or Internal Rate of Return (IRR) over a projected hold period.

How does interest rate affect cash on cash return?

Higher interest rates directly reduce cash on cash return because they increase monthly mortgage payments. On a $300,000 mortgage, the difference between a 4% and 7% rate is roughly $560/month — about $6,720/year in additional debt service. If your annual cash flow drops by $6,720 and your total cash invested stays the same, your CoC return falls proportionally. This is why CoC returns on investment properties bought in 2021–2022 at low rates look very different from deals bought in 2024–2025.
