Cap Rate vs Cash-on-Cash Return: Asset Yield vs Equity Yield
By Devon Coombs, CPA, MBA · Teaching Professor of Finance, Santa Clara University · Reviewed August 2026
Use the cap rate to price and compare properties, because it is an unlevered measure, NOI divided by value, that ignores financing entirely. Use cash-on-cash return to judge the current yield on invested equity, because it measures pre-tax cash flow after debt service against the dollars actually contributed. The cap rate describes what the asset earns; cash-on-cash describes what your money earns under a specific loan.
| Cap rate | Cash-on-cash return | |
|---|---|---|
| Formula | NOI ÷ property value | Annual pre-tax cash flow after debt service ÷ equity invested |
| Leverage | Unlevered; identical for every buyer | Levered; changes with loan terms |
| What it prices | The asset | The investor's equity position |
| Comparability | Comparable across buyers, markets, and time | Specific to one capital structure |
| Role in underwriting | Acquisition pricing and exit value assumptions | Current income test for the equity check |
When Cap rate is the right tool
The cap rate is the right lens for acquisition pricing, market comparison, and exit assumptions, because every buyer computes the same number regardless of financing. It converts income and value into a yield that can be tracked across submarkets, property types, and vintages. It is a single-year snapshot that works best on stabilized NOI, and it says nothing about growth, capital expenditures, or hold-period returns.
When Cash-on-cash return is the right tool
Cash-on-cash return is the right test once loan terms are on the table and the question becomes whether the equity check earns an acceptable current yield. It captures leverage directly, since cash-on-cash typically exceeds the cap rate when the loan constant sits below the cap rate and falls beneath it when the constant sits above. It measures only current cash, so it belongs alongside IRR and equity multiple rather than in place of them.
The common mistake
Buyers often compare a market cap rate against a cash-on-cash target as if the two were interchangeable yields, then conclude that a 5 percent cap rate market cannot satisfy an 8 percent cash return goal. The comparison is malformed because one metric is unlevered on value and the other is levered on equity, with the financing terms sitting between them. The same confusion runs in reverse when a leverage-inflated cash-on-cash figure is quoted as evidence the property itself is a bargain, even though the cap rate shows it was fully priced.
