Two of the most-quoted metrics in real estate — and the two most-confused. Cap rate is unlevered, ignores financing entirely. Cash-on-cash is levered, measures the actual yield on the cash you put in. Different inputs, different uses, both essential.
Use cap rate to compare properties against each other and against the market. Use cash-on-cash to evaluate the yield on your specific cash investment. A property's cap rate is fixed; its cash-on-cash changes with every financing structure you run.
Cap Rate and Cash-on-Cash measure different things.
| Cap Rate | Cash-on-Cash | |
|---|---|---|
| Formula | NOI ÷ Property Value | Annual Cash Flow ÷ Cash Invested |
| Considers financing? | No — purely a property yield | Yes — it's the levered return |
| What it answers | What is this property worth on yield? | What yield am I earning on my cash? |
| Typical range | 4-9% in most markets | 6-15% with 75% leverage on a normal deal |
| Best for | Cross-property comparison, market positioning | Personal deal evaluation, year-1 ROI |
| Includes appreciation? | No | No — both are cash flow only |
| Changes with leverage? | No — same regardless of loan | Yes — more leverage usually = higher cash-on-cash |
| Used by | Brokers, appraisers, institutions | Operators, retail investors, syndicators |
A duplex priced at $500,000 with $40,000 annual NOI.
Cap rate = $40,000 ÷ $500,000 = 8.0%. That's the property's yield, independent of how you buy it.
Now buy it with 25% down ($125,000 cash + $5,000 closing = $130,000 invested) and a 30-year loan at 7%:
Same property. Cap rate is 8.0%, cash-on-cash is 7.7%. The leverage amplified the dollar return per dollar invested but didn't lift the yield much because the loan rate (7%) is close to the cap rate (8%) — known as negative leverage when the spread is thin.
Drop the rate to 5% (refi or seller financing) and the numbers shift dramatically: debt service drops to ~$24,150, cash flow rises to $15,850, and cash-on-cash jumps to 12.2% — even though cap rate is still 8.0%. That's positive leverage at work.
Cap rate isn't your return — it's the market's pricing of the property. A 6% cap rate doesn't mean you're earning 6%. With 25% down and a 7% loan, your cash-on-cash could easily be 4-5% because debt service eats most of the NOI. Cap rate tells you whether you bought well; cash-on-cash tells you what you earn.
A 5% cap in Austin and a 9% cap in Cleveland aren't equivalent. The 5% reflects expected appreciation and rent growth (and low risk). The 9% reflects flat appreciation, higher vacancy risk, and management headache. Cap rate compresses risk + growth into one number — always compare within similar markets, not across them.
Cash-on-cash returns improve every year as rents grow and the loan amortizes. Year-1 CoC of 7% can be 11%+ by year 5 on a normal rental. Don't confuse the year-1 snapshot with average return — use total ROI or equity multiple for the multi-year story.
10%+ cash-on-cash typically requires either (a) a cap rate above 9%, which usually means a softer market with more operational risk, (b) high leverage (85%+ LTV) which amplifies downside, or (c) creative seller financing with terms that won't last. There's no free lunch in CoC — high yield = something is risky.
