Cash-on-cash return is a real estate metric that measures annual pre-tax cash flow divided by the total cash invested in a property. It answers the question: "For every dollar I put in, how many dollars come back to me in cash this year?" It excludes appreciation, principal paydown, and tax benefits—focusing only on actual cash in versus cash out.
Cash-on-cash return is one of the first numbers rental investors calculate because it strips away speculation and tells you what a property actually pays. Unlike cap rate, which uses property value as the denominator, cash-on-cash uses your cash invested—making it personal to your financing structure.
Key takeaway
The formula
Cash-on-cash return = Annual pre-tax cash flow ÷ Total cash invested
Annual pre-tax cash flow is rental income minus operating expenses (taxes, insurance, maintenance, management, vacancy reserve) minus debt service. Total cash invested includes down payment, closing costs, and upfront repairs—not the total purchase price.
Worked example
You buy a rental for $200,000 with a $40,000 down payment and $5,000 in closing costs. After $10,000 in immediate repairs, your total cash invested is $55,000. The property rents for $1,800/month ($21,600/year). Annual operating expenses run $8,000 and your mortgage payment is $10,200/year.
Annual cash flow = $21,600 − $8,000 − $10,200 = $3,400. Cash-on-cash return = $3,400 ÷ $55,000 = 6.2%.
When cash-on-cash matters most
- Comparing leveraged deals. Two properties with identical cap rates can have wildly different cash-on-cash returns depending on financing.
- Evaluating partnerships.Each partner's cash-on-cash may differ based on equity split and preferred returns.
- Stress-testing rate changes. If your cash-on-cash is thin at current rates, refi or rate hikes can flip it negative fast.
What cash-on-cash ignores
- Appreciation. Your total return includes property value growth, but cash-on-cash excludes it entirely.
- Principal paydown. Each mortgage payment builds equity, but only the interest portion affects cash-on-cash.
- Tax benefits. Depreciation deductions improve after-tax returns but do not appear in cash-on-cash.
