Cap Rate vs. Cash-on-Cash Return: What NNN Investors Need to Know

Two Metrics, Two Entirely Different Questions

When evaluating NNN properties, two metrics dominate the conversation: capitalization rate (cap rate) and cash-on-cash return. Experienced investors know exactly what each measures. Many newer investors confuse them — and that confusion can lead to costly miscalculations.

Cap Rate: Property Value in Relation to Income

A cap rate answers the question: "What is this property worth relative to its income, assuming I paid all cash?"

Formula: Cap Rate = Net Operating Income (NOI) ÷ Purchase Price

Example: A Walgreens paying $300,000 annual rent purchased for $5,500,000 has a cap rate of 5.45%.

Cap rate is a property-level metric. It ignores financing completely. Two investors can buy the exact same property — one paying all cash, one financing 65% — and they'll both calculate the same cap rate because it doesn't matter how they paid for it.

Cap rate is primarily used to:

• Compare property values across different markets
• Assess whether a listing is priced fairly relative to current market rates
• Track market-level trends (cap rate compression or expansion)

Cash-on-Cash Return: Your Actual Return on Invested Capital

Cash-on-cash return answers the question: "What return am I getting on the actual dollars I invested, accounting for my financing?"

Formula: Cash-on-Cash = Annual Pre-Tax Cash Flow ÷ Total Cash Invested

Example: Same Walgreens. You put 35% down ($1,925,000), finance $3,575,000 at 6.5% over 25 years (monthly payment ~$24,100 = $289,200 annually). Your cash flow is $300,000 − $289,200 = $10,800/year. Cash-on-cash = $10,800 ÷ $1,925,000 = 0.56%.

With interest rates at 2022 levels (3.5%), that same deal might cash-on-cash at 4–5%. This is why rising interest rates have such a dramatic impact on NNN investor returns — cap rates are slow to move, but financing costs change immediately.

When Cap Rate and Cash-on-Cash Diverge

Here's where investors get confused: you can have a high cap rate with a terrible cash-on-cash return, and vice versa.

A 7.0% cap rate property financed at 7.5% interest will produce negative cash flow (the loan costs more than the property earns). This is called negative leverage — a real and growing issue in today's rate environment.

A 4.5% cap rate property bought all-cash generates exactly 4.5% cash-on-cash. Simple and predictable.

The All-Cash NNN Strategy

Many 1031 exchange investors buy NNN properties all-cash. This is particularly common when investors have a large equity position from a sold property (often $3M–$10M+) and want maximum simplicity and predictability. All-cash NNN ownership produces exactly the cap rate as your yield — no financing risk, no negative leverage risk, no variable rate exposure.

For all-cash investors, NNN cap rates of 5.0–6.5% compare favorably to money markets (4.5–5.5%), treasury bonds (4–5%), and dividend stocks (2–3%) — with the added benefit of real property appreciation over time.

Which Metric Matters Most?

Both matter, just for different purposes:

• Use cap rate to evaluate whether you're paying a fair price for a property relative to market
• Use cash-on-cash to evaluate whether the deal makes financial sense given your specific financing

Never buy a NNN property based solely on cap rate without running cash-on-cash projections at your actual financing terms. And never evaluate your property's market value based on cash-on-cash — your lender's appraisal will always use cap rate.
