What Is Cash-on-Cash Return?
Cash-on-cash (CoC) return is the annual pre-tax cash income earned on the actual cash you invested in a rental property, expressed as a percentage. The formula is simple: CoC Return = Annual Pre-Tax Cash Flow / Total Cash Invested × 100. If you invest $60,000 in down payment and closing costs and the property generates $6,000 in net cash flow after all expenses and mortgage payments, your CoC return is 10%.
Unlike cap rate — which ignores financing — cash-on-cash return includes your mortgage payment in the expense calculation. This makes it the most relevant metric for leveraged real estate investments. It tells you exactly how efficiently your deployed capital is working.

How to Calculate Cash-on-Cash Return Step by Step
Step 1: Calculate Effective Gross Income (EGI). EGI = (Monthly Rent × 12) × (1 − Vacancy Rate) + Other Annual Income. If monthly rent is $2,000 with 8% vacancy: EGI = ($24,000 × 0.92) = $22,080.
Step 2: Calculate Net Operating Income (NOI). NOI = EGI − All Operating Expenses. Operating expenses include property taxes, insurance, management fees, maintenance, CapEx reserves, and any HOA or utilities paid by the owner. NOI excludes mortgage payments.
Step 3: Calculate Pre-Tax Cash Flow. Cash Flow = NOI − Annual Debt Service (12 × monthly mortgage payment).
Step 4: Divide by total cash invested (down payment + closing costs + upfront rehab). This gives you CoC return as a decimal — multiply by 100 for percentage.
Cash-on-Cash Return Benchmarks for 2026
| CoC Return | Deal Quality | Market Type | Action |
|---|---|---|---|
| Below 5% | Weak | High-appreciation coastal | Only if banking on appreciation |
| 5–7% | Acceptable | Major metro, stable | Proceed with caution |
| 8–12% | Good | Midwest, Sun Belt | Strong deal — analyze further |
| 12–15% | Excellent | B/C class markets | Pursue aggressively |
| 15%+ | Outstanding | Deep value / high risk | Verify risk factors |
Cash-on-Cash Return Calculator: 2026 Worked Example for a $350,000 Rental Property
Walk through a concrete 2026 deal using the cash-on-cash return calculator above. A single-family rental in a Sun Belt market: $350,000 purchase price, 25% down ($87,500), $12,000 closing costs + $8,000 initial rehab = $107,500 cash in. Financing: 30-year fixed at 6.8% on a $262,500 loan = $1,712/month principal + interest. Gross rent: $2,650/mo × 12 = $31,800. Operating expenses: property tax $4,200, insurance $1,800, property management 10% = $3,180, maintenance + CapEx reserve 1.5% of value = $5,250, vacancy 8% = $2,544. Total opex: $16,974. Annual debt service: $1,712 × 12 = $20,544. Pre-tax annual cash flow: $31,800 − $16,974 − $20,544 = −$5,718 (negative). Cash-on-cash return: −5.3% in year 1. This is the trap most 2026 buyers fall into — 6.8% mortgage rates pushed leveraged returns negative for most metros below $2,800/mo rent. To hit the 8% CoC benchmark, either rent must rise to ~$3,300/mo, purchase price drop to ~$295,000, or you find an assumable VA/FHA loan at 3–4%.

Cash-on-Cash Return Calculator: BRRRR Strategy Refinance Boost in 2026
The BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat) makes the cash-on-cash return calculator swing dramatically once you cash out. A typical 2026 BRRRR deal: buy a $200,000 distressed single-family with $50,000 cash purchase, put $30,000 into rehab ($80,000 cash in). After-repair value (ARV) hits $310,000. Refinance at 75% LTV = $232,500 loan payoff — you pull $152,500 back out, leaving only −$72,500 cash in the deal (you have more cash than you started). Now the rental cash flow of $3,600/yr on effectively negative cash-in produces an infinite CoC return (any positive number ÷ zero-or-less denominator). The Freddie Mac Primary Mortgage Market Survey shows 30-year fixed rates in the 6.5–7.0% range for 2026, which sets your refi payment. Two 2026 catches: (1) most lenders require 6-month seasoning on the refi (deed-recorded date), (2) DSCR loans on investment BRRRRs price 100–150 bps above owner-occupied — factor both into the model above.

Cash-on-Cash Return vs Cap Rate vs ROI
Cap rate (capitalization rate) measures NOI divided by property value — it ignores financing entirely. Cap rate is useful for comparing properties on a market-value basis and for estimating what a property would sell for. Cash-on-cash return accounts for your specific financing terms, so two investors buying the same property with different down payments will have different CoC returns but the same cap rate.
Total ROI includes equity appreciation, principal paydown, depreciation tax shields, and refinancing proceeds in addition to cash flow. CoC return is a snapshot of current income efficiency; total ROI captures long-term wealth building. Most professional investors screen deals with CoC first, then model total ROI for final underwriting. The IRS Schedule E (irs.gov) and related tax publications outline how rental income and expenses are reported for tax purposes.
Typical Cash-on-Cash Return Ranges by Property Type & Market (2026)
Use this table to sanity-check the cash-on-cash return calculator output above. If your CoC lands well outside the typical band for your property class, the model likely has an input error (rent optimistic, opex under-modeled, or expenses miscategorized). 2026 mortgage rates (6.5-7.0% per Freddie Mac PMMS) have compressed leveraged returns across all classes.
| Property Type | Market | CoC Range (2026) | Notes |
|---|---|---|---|
| Single-Family Rental | Sun Belt / Midwest | 4% – 9% | Sweet spot: rent-to-price > 0.9% |
| Single-Family Rental | Coastal / Tier 1 | −4% – 3% | Appreciation-driven, not cash-flow |
| Small Multifamily (2-4 unit) | Midwest / Rust Belt | 6% – 12% | FHA house-hack lifts CoC 3-5 pts |
| Short-Term Rental (STR) | Tourist metro | 8% – 18% | High opex, regulation risk |
| Commercial NNN Lease | Any | 5% – 8% | Stable, low management |
| BRRRR post-refi | Any | 15% – ∞ | Infinite CoC if all cash pulled out |
The 8% CoC benchmark commonly cited on BiggerPockets applies best to leveraged Sun Belt SFR deals — coastal buyers rarely hit it without appreciation-heavy underwriting. Verify property tax rate against county assessor, insurance quote from a real broker, and PM fee from a local operator before running the cash-on-cash return calculator above. Updated 2026-07-27.
Cash-on-Cash Return Calculator: 5 Common Modeling Errors That Overstate Returns 3-8%
Deals that pencil at 10% CoC on paper often deliver 2-4% real-world CoC because five modeling errors compound in the same direction. Watch for these before hitting "buy". (1) Ignoring CapEx reserves — roof, HVAC, water heater, appliances have finite lives; failing to reserve 1-2% of property value annually (~$3,500-$7,000/year on a $350K home) drops actual CoC by 2-4 percentage points. (2) Understating vacancy — using 5% when the Census Bureau American Community Survey shows the local rental vacancy rate is 8-10%; a 3-point vacancy miss cuts $795/year on $26,500 gross rent. (3) Missing PM turnover fees — most PMs charge 50-100% of one month's rent every time a tenant turns over (12-24 month cycle), typically not included in the base 10% PM fee. (4) Forgetting HOA + special assessments — condos and PUDs often have $200-$600/mo HOA plus periodic 4-figure special assessments; both hit cash flow. (5) Assuming rent = advertised rent — tenants negotiate, concessions happen, effective rent typically runs 3-6% below advertised. Per Freddie Mac Multifamily research, national single-family rental effective rent grew only 2.4% in 2024 despite advertised rent growth of 4.1% — the gap is negotiation and turnover. Add these 5 conservatives to any cash-on-cash return calculator run before committing capital. Updated 2026-07-27.
Frequently Asked Questions
What is a good cash-on-cash return for rental property?
Most real estate investors target a cash-on-cash return of 8-12% or higher. Returns of 5-7% are considered acceptable in low-risk, appreciating markets. Returns above 12% indicate strong cash flow but may also signal higher risk or a lower-appreciation market. According to the National Association of Realtors, single-family rental yields vary significantly by metro area.
How is cash-on-cash return different from ROI?
Cash-on-cash (CoC) return measures only the annual pre-tax cash flow divided by total cash invested. ROI typically includes all returns — appreciation, equity paydown, tax benefits — not just cash. CoC is better for comparing the cash efficiency of different financing structures, while total ROI better captures overall wealth-building.
What cash invested should I include in the calculation?
Total cash invested includes your down payment, closing costs, upfront rehab or repair costs, and any reserves you deposited at closing. If you used cash to purchase outright, the total purchase price is your invested capital. Do not include financed amounts — only the actual dollars you deployed from your own pocket.
Does cash-on-cash return include mortgage payments?
Yes. Annual cash flow (the numerator) is calculated after mortgage principal and interest payments. You subtract all operating expenses AND total debt service from gross rent to arrive at pre-tax cash flow. This is what makes CoC meaningful — it shows how much your actual invested dollars return after covering all costs including the mortgage.
What is a realistic vacancy rate to use?
The U.S. national average vacancy rate for rental units is approximately 6-7% (U.S. Census Bureau). For single-family homes in suburban markets, 5-8% is typical. Urban apartments in tight markets may run 3-5%. Rural or high-turnover properties may see 10-15%. Most underwriting models use 8-10% as a conservative baseline.
How do I calculate annual cash flow from monthly rent?
Annual cash flow = (Gross annual rent) − (Vacancy allowance) − (Operating expenses) − (Annual debt service). Operating expenses typically include property taxes, insurance, property management (8-12% of rent), maintenance (1% of value/year), and capital expenditure reserves. Annual debt service is 12 × monthly mortgage payment.
Why is my cash-on-cash return calculator result negative in 2026?
Negative CoC in 2026 is common because 30-year fixed mortgage rates are still 6.5%-7.0% — roughly double the 2021 lows of 3.0%. At 6.8% on a 25%-down rental purchase, debt service eats most of the rent before opex. Three fixes: (1) larger down payment (40-50%) lowers debt service; (2) house-hack or owner-occupy first to access FHA/VA rates under 5%; (3) target markets where rent-to-price is above 0.9% (price/rent ratio under 110). The Sun Belt + lower Midwest still has scattered 0.9%+ rent-to-price deals; coastal metros are typically 0.4%-0.6% (impossible for positive leveraged CoC at current rates).
Should I include depreciation tax savings in the cash-on-cash return calculator?
No — by convention, cash-on-cash return is pre-tax. Depreciation (typically 27.5-year straight-line for residential) creates a paper loss that shelters cash flow from federal income tax but does not change actual cash in your bank account. Include depreciation only when modeling total ROI or after-tax return. The IRS allows passive activity loss rules to limit depreciation deductions for high-income investors; see IRS Publication 925 for the $25,000 special allowance ($150K AGI phase-out) for active landlord participation.
What is a realistic cash-on-cash return for a Sun Belt rental in 2026?
For a leveraged single-family rental in Sun Belt or Midwest markets (25% down, 6.8% mortgage), realistic CoC is 4-9% depending on rent-to-price ratio. Deals with rent-to-price above 0.9% (e.g., $250,000 property renting for $2,250/mo) tend to clear 6% CoC. Coastal metros with rent-to-price under 0.6% often produce negative CoC at 2026 rates — those deals rely on appreciation, not cash flow. Sanity-check any CoC over 15% on a stabilized property: the model probably under-counts vacancy, maintenance, or CapEx reserves.
Can I reach 12% or higher cash-on-cash return in 2026 without BRRRR?
Rarely on a stabilized long-term rental at 25% down and 2026 mortgage rates. Paths to 12%+ CoC without BRRRR: (1) short-term rental in a tourist metro (10-18% typical but factors in high opex/regulation risk), (2) small multifamily house-hack with FHA 3.5% down (leverages ratio dramatically), (3) subject-to or assumable mortgage under 5% APR, (4) all-cash purchase in a Class-C SFR at 12%+ gross yield. BRRRR remains the cleanest 12%+ path because pulling cash out mathematically shrinks the denominator.
What CapEx reserve should I include in the cash-on-cash return calculator?
Use 1-2% of property value annually for CapEx reserves — roof (~25-year life), HVAC (~15 years), water heater (~10 years), appliances (~10 years), flooring (~15 years). On a $350,000 property that is $3,500-$7,000/year. Skipping CapEx is the #1 reason new investors overstate cash-on-cash return by 2-4 percentage points. On top of the base 10% PM fee, add lease-up/turnover fees (50-100% of one month rent per tenant turnover, ~1-2 year cycle). Freddie Mac research shows effective rent runs 3-6% below advertised, so also discount the gross rent input.
How does the American Community Survey vacancy rate affect my cash-on-cash return?
The US Census American Community Survey and Housing Vacancy Survey publish local rental vacancy rates by MSA — free at census.gov. National average is 6-7% but individual markets range 3% (Boise, Nashville) to 12% (Detroit, Memphis pockets). Using the national default when your local rate is 8-10% overstates CoC by ~0.5-1 percentage point. Always pull the actual county-level vacancy rate before finalizing a deal. Combined with 5% concession/turnover discount from advertised rent, most 2026 investors should model 10-13% effective vacancy to reach conservative underwriting.
