Cash-on-Cash Return Calculator Guide: Is Your Rental Property Profitable? (2026)
Quick Answer
Cash-on-cash return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested. If you invested $50,000 in down payment and closing costs, and the property generates $4,000/year in cash flow after all expenses and mortgage payments, your cash-on-cash return is 8%. Most real estate investors target 8–12% cash-on-cash return.
The Cash-on-Cash Return Formula
Cash-on-cash return (CoC) measures how much cash income you receive each year relative to the cash you actually put into a deal. It answers the question every rental investor cares about: for every dollar I put in, how many cents do I get back each year in my pocket?
Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
What counts as “total cash invested”?
Total cash invested includes every dollar you spent out of pocket to acquire and prepare the property:
- Down payment— typically 20–25% of the purchase price for investment properties
- Closing costs— lender fees, title insurance, attorney fees, recording fees; typically 2–5% of the loan amount
- Rehab and repairs— any upfront renovation costs before the property is rent-ready
- Initial reserves— some investors include the cash reserves they set aside for the property at purchase
Do not include the mortgage loan amount. You did not write that check — the bank did. Cash-on-cash only counts the money that left your account.
What counts as “annual pre-tax cash flow”?
Annual pre-tax cash flow is what remains after collecting rent and paying every cash expense, including the mortgage. Work down from gross rent:
- Gross scheduled rent— full rent if occupied all year
- Minus vacancy allowance— typically 5–8% of gross rent; NAR data shows national average vacancy for single-family rentals around 6–7%
- Minus operating expenses— property taxes, insurance, property management (8–12% of collected rent), HOA fees, maintenance, and capital expenditure reserves
- This gives you Net Operating Income (NOI)
- Minus annual debt service— your total mortgage payments for the year (principal + interest)
- = Annual pre-tax cash flow
Cash flow is pre-tax because investors are in different tax brackets and depreciation affects everyone differently. CoC gives you an apples-to-apples comparison before tax variables enter the picture.
What Is a Good Cash-on-Cash Return?
According to a BiggerPockets investor survey, the median cash-on-cash return target among active U.S. real estate investors is 8–10%. But “good” depends heavily on your market, strategy, and risk tolerance.
| Cash-on-Cash Return | Rating | Typical Context |
|---|---|---|
| Under 5% | Poor | High-cost markets (NYC, SF); investors relying on appreciation |
| 5–8% | Fair | Coastal and gateway cities; stable but modest cash flow |
| 8–12% | Good | Midwest and Sun Belt markets; solid cash-flow properties |
| 12%+ | Excellent | Value-add deals, short-term rentals, or secondary markets with higher risk |
Roofstock's 2025 rental market data shows average CoC returns ranging from about 4% in Los Angeles to 10–12% in markets like Memphis, Cleveland, and Indianapolis. The Midwest and South consistently produce higher cash-on-cash returns because property prices are lower relative to rents.
One important nuance: high CoC return and low appreciation often go together. A 12% CoC in a struggling Rust Belt city may produce less total wealth than a 5% CoC in a high-growth Sun Belt city over a 10-year hold. Use CoC to evaluate immediate cash flow; use total IRR to evaluate the full investment.
Cash-on-Cash vs Cap Rate vs ROI: Key Differences
These three metrics confuse a lot of investors. They measure different things, and each has its place.
| Metric | Formula | Includes Financing? | Best Used For |
|---|---|---|---|
| Cap Rate | NOI ÷ Property Value | No | Comparing properties regardless of how they're financed |
| Cash-on-Cash | Annual Cash Flow ÷ Cash Invested | Yes | Evaluating your actual return on the cash you put in |
| Total ROI | (Cash Flow + Appreciation + Equity) ÷ Cash Invested | Yes | Measuring full return over a holding period |
Cap rate vs CoC
Cap rate is a property-level metric — it tells you the return a property generates as if you paid all cash. It's useful for comparing two properties in the same market. Cash-on-cash is an investor-level metric — it reflects what you personally earn based on your financing terms. Use cap rate to evaluate the deal; use cash-on-cash to evaluate whether the deal works for your specific financing.
CBRE's 2025 rental market research shows average cap rates of 5.0% for apartment buildings nationally. A property with a 5% cap rate and a 7% mortgage rate generates negative cash flow on a 20% down payment — which is exactly why cash-on-cash matters as a separate check.
CoC vs total ROI
Cash-on-cash ignores appreciation, mortgage paydown, and tax benefits. A property with 6% CoC could deliver a 15% total annual return if the property appreciates 8% per year and you're building equity through principal paydown. CoC is useful for screening deals fast; total ROI tells you whether to hold long-term.
Worked Example: Calculating CoC on a $250,000 Rental
Let's walk through a complete cash-on-cash calculation on a $250,000 single-family rental in a Midwest market.
Purchase details
| Item | Amount |
|---|---|
| Purchase price | $250,000 |
| Down payment (20%) | $50,000 |
| Loan amount | $200,000 |
| Interest rate | 7.25% (30-year fixed) |
| Closing costs (estimated) | $4,500 |
| Minor repairs before renting | $2,000 |
| Total cash invested | $56,500 |
Annual income and expenses
| Item | Monthly | Annual |
|---|---|---|
| Gross rent | $1,850 | $22,200 |
| Vacancy (6%) | –$111 | –$1,332 |
| Property taxes | –$208 | –$2,500 |
| Insurance | –$100 | –$1,200 |
| Property management (10%) | –$174 | –$2,087 |
| Maintenance & repairs (1% of value) | –$208 | –$2,500 |
| CapEx reserve | –$100 | –$1,200 |
| Net Operating Income (NOI) | $949 | $11,381 |
| Mortgage payment (P+I) | –$1,366 | –$16,392 |
| Annual pre-tax cash flow | –$417 | –$5,011 |
At 7.25% interest with 20% down, this property generates negative cash flow. The Federal Reserve's 2025 mortgage rate data confirms that 30-year fixed rates in the 7%+ range make it difficult to achieve positive cash-on-cash returns in markets where cap rates are below 6%.
What changes the outcome?
If the same property could be purchased for $210,000 (a better deal), or rented for $2,100/month (stronger rental market), the math shifts:
| Scenario | Annual Cash Flow | Cash-on-Cash Return |
|---|---|---|
| Base case ($250K / $1,850 rent) | –$5,011 | –8.9% |
| Better deal ($210K / $1,850 rent) | +$1,108 | +2.3% |
| Better rent ($250K / $2,100 rent) | –$1,961 | –3.5% |
| Both ($210K / $2,100 rent) | +$4,158 | +8.6% |
The lesson: in a 7%+ rate environment, buying at the right price matters more than ever. Our Cash-on-Cash Return Calculator lets you model these scenarios instantly.
5 Strategies to Improve Cash-on-Cash Return
1. Increase rents to market rate
Many landlords underprice. According to Roofstock data, properties managed by professional managers achieve rents 6–10% higher than self-managed properties in the same zip code. Research comparable rents quarterly and raise to market on each lease renewal. A $100 increase in monthly rent adds $1,200 to annual cash flow — that can swing CoC by 2+ percentage points on a $50K investment.
2. Reduce vacancy with better tenant retention
Vacancy is one of the biggest killers of CoC return. Each month vacant on a $1,850/month rental costs you $1,850 in lost income. Proactive maintenance, responsive communication, and reasonable rent increases keep good tenants in place. Offer 12-month leases with a small discount versus month-to-month to reduce turnover risk.
3. Refinance at a lower rate when rates drop
A 1% reduction in mortgage rate on a $200,000 loan saves roughly $115/month in debt service — about $1,380/year. On a $50,000 cash investment, that turns a 2% CoC into a 4.8% CoC. Watch rates and model the break-even on refinance costs when rates fall 0.75% or more below your current rate.
4. Add income streams
Accessory dwelling units (ADUs), garage conversions, storage rentals, laundry machines, and parking spots all add income without increasing your cash invested. CBRE research shows that ADUs can increase net operating income by 20–40% on single-family properties in permissive markets. Even a $150/month storage or parking add-on meaningfully improves CoC.
5. Convert to short-term rental where market supports it
Short-term rentals (Airbnb, VRBO) can generate 2–3× the gross rent of long-term rentals in the right markets. The trade-off is higher operating costs, more management time, and local regulation risk. NAR investor data shows that short-term rental operators in vacation markets report median CoC returns of 10–18% — well above long-term rental norms. Verify local regulations before converting.

Frequently Asked Questions
What is a good cash-on-cash return for a rental property?
Most real estate investors target 8–12% cash-on-cash return. According to a BiggerPockets investor survey, the median CoC target among active investors is around 8–10%. Returns above 12% are considered excellent but often come with higher risk, lower-priced markets, or properties requiring significant management effort. Under 5% is generally considered poor, though some investors accept lower returns in appreciation-heavy markets like San Francisco or New York.
What is the difference between cash-on-cash return and cap rate?
The key difference is financing. Cap rate ignores how you paid for the property — it divides Net Operating Income by the total property value, regardless of whether you used cash or a mortgage. Cash-on-cash return divides annual pre-tax cash flow (after debt service) by the actual cash you invested. If you put 20% down with a mortgage, your cash-on-cash return will be higher than your cap rate when the property performs well, because leverage amplifies returns.
Does cash-on-cash return include appreciation?
No. Cash-on-cash return only measures the cash income generated relative to the cash invested — it does not include property appreciation, equity paydown from mortgage amortization, or tax benefits like depreciation deductions. For total return analysis, investors use a full ROI calculation or internal rate of return (IRR) that captures all those components over a holding period.
How do you calculate cash-on-cash return?
Cash-on-cash return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested. Annual pre-tax cash flow is your gross rent minus all operating expenses (property management, insurance, taxes, maintenance, vacancy reserve) minus your annual mortgage payments (principal + interest). Total cash invested is your down payment plus closing costs plus any upfront rehab or repair costs.
Can cash-on-cash return be negative?
Yes. A negative cash-on-cash return means the property generates negative cash flow — your expenses and mortgage payments exceed your rental income. This is common in high-cost markets and during periods of high interest rates. Some investors accept negative cash flow when they expect strong appreciation, but it requires sufficient reserves to cover monthly shortfalls and adds significant financial risk.
What expenses should I include when calculating cash-on-cash return?
Include all recurring operating expenses: property taxes, landlord insurance, property management fees (typically 8–12% of rent), maintenance and repairs (budget 1% of property value per year), vacancy allowance (typically 5–8% of gross rent), HOA fees if applicable, and capital expenditure reserves for big-ticket items like roof, HVAC, and appliances. Then subtract your full mortgage payment (principal + interest). Do not include depreciation or income taxes, as cash-on-cash is a pre-tax metric.
