Cash-on-Cash Return Calculator

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

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%. For tax treatment of rental income, see IRS Publication 527. Updated 2026-06-27.

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.

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 2026-07-15.
