Cap Rate
vs
Cash-on-Cash Return
Cap rate measures a property's unlevered year-one yield (NOI ÷ purchase price); cash-on-cash return measures the levered year-one yield on your equity (annual cash flow after debt service ÷ total cash invested).
TL;DR
Cap rate is about the property. Cash-on-cash is about your deal. You use cap rate to compare properties; you use cash-on-cash to evaluate how leverage and equity structure affect your return. Neither captures total return — both ignore appreciation, tax benefits, and exit.
What is Cap Rate?
Cap rate = NOI ÷ Purchase Price. It expresses the unlevered year-one yield on a property — what you'd receive in cash if you bought all-cash. Cap rate is the standard comparable across properties because it removes financing and equity structure. It's a snapshot, not a return.
What is Cash-on-Cash Return?
Cash-on-Cash Return = (NOI − Annual Debt Service) ÷ Total Cash Invested. It measures the pre-tax cash flow on your actual equity investment after debt service. Cash-on-cash is affected by leverage: more debt typically increases cash-on-cash when the cap rate exceeds the loan constant, decreases it when debt costs exceed property yield.

Cap Rate vs Cash-on-Cash Return — the differences.
| Dimension | Cap Rate | Cash-on-Cash Return |
|---|---|---|
| Formula | NOI ÷ Purchase Price | (NOI − Debt Service) ÷ Cash Invested |
| Considers financing | No — unlevered | Yes — levered |
| Time horizon | Year-one snapshot | Year-one snapshot |
| Captures appreciation | No | No |
| Captures tax benefits | No | No (pre-tax measure) |
| Best use | Comparing similar properties | Evaluating your specific deal structure |
| Units | Percentage | Percentage |
| Sensitivity to leverage | None | High — more debt can increase or decrease |
| Typical range (2026) | 4.5–9% depending on asset class | 5–12% depending on leverage and property |
When to use Cap Rate
- You're comparing properties across different financing structures
- You're talking to a seller who uses cap rate as pricing shorthand
- You need a fast metric to value a stabilized property
- You're calculating implied property value from NOI
When to use Cash-on-Cash Return
- You want to know your year-one return on your equity
- You're comparing how different leverage structures affect your deal
- You're marketing a syndication offering to investors
- You want a simple current-yield-on-equity measure
Verdict
They measure different things. Cap rate is the market's price on the property; cash-on-cash is what that property does for your equity given your financing. Use both together. Add IRR and equity multiple for the full picture over hold period.
Frequently asked questions
Is cap rate or cash-on-cash better?
Neither is 'better' — they measure different things. Cap rate compares properties; cash-on-cash evaluates how financing and equity structure affect your specific deal. Sophisticated underwriting uses both alongside IRR and equity multiple.
Can cash-on-cash exceed cap rate?
Yes, through positive leverage. When the cap rate exceeds the loan constant (interest rate plus amortization), adding debt increases cash-on-cash relative to cap rate. This is how leverage amplifies returns in favorable rate environments.
Why isn't cash-on-cash the same as IRR?
Cash-on-cash is a year-one number that ignores principal paydown, appreciation, and exit proceeds. IRR is a time-weighted total return over the full hold period that includes all those factors. IRR is more complete but relies on more assumptions.
