What is cash-on-cash return?

Cap rate ignores leverage. Cash-on-cash doesn't.

Cash-on-cash return (CoC) is the cash flow a property generates divided by the cash you put in. Unlike cap rate, it accounts for financing — if you borrow 80%, your CoC could be 12% on a property with a 6% cap rate because your $90K down is doing the work of a $450K asset.

Most investors graduate from cap rate to CoC once they have one or two properties under their belt. Cap rate tells you which properties are worth a second look; CoC tells you which financing structure makes the most sense for a given property.

CoC also reveals when leverage hurts. If rates rise faster than rents grow, the same property can have a great cap rate but a negative cash-on-cash — you're bleeding cash every month even though the building is profitable on paper. Our calculator flags this as DIFFICULT in the AI verdict.

The formula
CoC = (NOI − Annual Debt Service) ÷ Cash Invested
Worked example
  • Annual rent: $36,000
  • Op-ex (30%): −$10,800
  • NOI: $25,200
  • Annual debt service (P&I × 12): −$26,929
  • Annual cash flow: −$1,729
  • Cash in (20% down + $8K closing): $98,000
  • Cash-on-cash: −1.76% (DIFFICULT)
Cash-on-Cash Return FAQ
What's a "good" cash-on-cash return?

8% used to be the floor for serious income investors. In 2026 with high interest rates, 5–7% is now realistic in most markets; anything above 8% usually requires the BRRRR strategy or extremely high-rent markets. Below 3% you're basically betting on appreciation, which is a different game.

CoC vs. cap rate — which one matters?

Both, for different things. Cap rate is your screening tool when you're scanning 50 listings: it filters out properties that don't cash-flow at any reasonable leverage. CoC is your decision tool once you've narrowed to 3 candidates: it tells you which financing structure (and down payment %) optimizes your return.

Does CoC include appreciation?

No. CoC is a pre-tax cash yield only. It excludes principal paydown (you're building equity but not pocketing it), appreciation, depreciation tax shield, and any value-add work. That's why BRRRR investors also track IRR — internal rate of return — which captures the full picture but is harder to compute on a napkin.

How does the AI verdict treat CoC?

CoC drives the PASS / STRETCH / DIFFICULT call: above 3% is PASS, 0–3% is STRETCH, negative is DIFFICULT. The AI then runs 3 what-if scenarios (rate +1pt, rent −10%, vacancy 15%) and recomputes CoC for each — so you see whether your "PASS" survives realistic stress, or whether it crumbles when the lease comes up for renewal.
