Both measure return. One ignores financing, the other does not. Both can mislead you if you rely on either alone.

Cap rate is NOI divided by purchase price. It deliberately ignores how the deal is financed, which makes it the right metric for comparing properties without your specific debt situation distorting the comparison. When you see a market report say multifamily cap rates are at 6.1%, that figure describes the income yield of the asset itself, not the return any particular investor earns after applying leverage.
cap_rate = NOI / purchase_priceAccording to J.P. Morgan commercial real estate research, national multifamily cap rates held near 6.1% in Q4 2024 and remained unchanged through Q4 2025.[1] Arbor Realty Trust data show average single-family rental cap rates reached 6.8% in Q2 2024, the highest level since Q1 2018.[2] Rising rates drove buyers to demand higher unlevered yields to make deals pencil.
Cash-on-cash return divides annual cash flow after debt service by the cash you actually put into the deal: down payment plus closing costs. It tells you the year-one return on your out-of-pocket capital. This is the metric that matters when you are personally allocating capital and need to know what you will actually see in your checking account.
cash_on_cash = annual_cash_flow_after_debt_service / (down_payment + closing_costs)Cash-on-cash is highly sensitive to interest rates. The same property at the same purchase price produces a very different cash-on-cash return depending on the rate. At the Freddie Mac 30-year fixed rate of 6.48% as of June 2026, annual debt service on an $240,000 loan (80% LTV on a $300,000 property) runs roughly $18,200.[3] At 4.5%, the same loan costs about $14,600 per year. That $3,600 difference directly reduces cash-on-cash return, with no change to cap rate at all.
Cap rate matters when you are comparing properties across different markets or evaluating what an all-cash buyer would pay for a deal. It is the right lens for valuation conversations, for benchmarking against market data, and for stress-testing what the deal looks like if you paid cash. Institutional buyers think in cap rates because they often have access to capital at rates that look different from retail leverage.
Cash-on-cash matters when you are personally deploying capital and need to know the year-one yield on what you are putting in. A property might look unimpressive on cap rate but excellent on cash-on-cash if you have access to below-market financing. The reverse is equally true: a strong cap rate can become negative cash-on-cash when rates are high.
Cash-on-cash returns are extremely sensitive to leverage. A 6% cap rate with 80% LTV at 7% interest routinely produces negative or near-zero cash-on-cash in the first year. The same deal with 50% down looks attractive: less debt service, more net cash flow, better year-one return. Cap rate stays the same in both cases.
The trap is when investors screen deals by cash-on-cash return at high leverage and conclude the deal is "a 10% cash-on-cash return." They have improved the metric by adding debt, not by improving the underlying property. When vacancy rises or rates change, the high-leverage deal breaks down faster. Looking at cap rate alongside cash-on-cash keeps both views on the table.
Consider a property purchased at $350,000 with $28,000 in annual NOI. Cap rate is 8.0%. Now apply two financing scenarios using current Freddie Mac rate data:
The cap rate is 8.0% in both cases. The cash-on-cash return differs by 2.7 percentage points purely because of the rate. If rates move further, or the deal is evaluated at higher LTV, the divergence grows. This is why underwriters look at both metrics on every deal.
Use cap rate to decide if the property is worth buying at the price. If the cap rate is below the going rate for similar assets in that market, you are paying a premium you need a reason to justify. Use cash-on-cash to decide if the financing structure makes the deal work for your actual capital. A deal can have a reasonable cap rate and still not make sense for a buyer applying high leverage in a high-rate environment.
The RentalAnalytics cap rate calculator outputs both metrics from a single set of inputs. The cash flow analyzer adds break-even occupancy and a full projected P&L, which gives you the downside picture alongside the return picture.
Cap rate measures unlevered property yield (NOI divided by purchase price) and ignores how the deal is financed. Cash-on-cash return measures the levered yield (annual cash flow after debt service divided by cash invested). The two metrics can diverge sharply when interest rates are high.
Average single-family rental cap rates reached 6.8% in Q2 2024 according to Arbor Realty Trust, the highest since Q1 2018. Multifamily cap rates nationally held near 6.1% in Q4 2024 per J.P. Morgan. A good cap rate depends on the market, property type, and your required return.
Yes. A property with a 6% cap rate financed at 80% LTV with a 7% interest rate will commonly produce negative cash-on-cash return in year one. The debt service exceeds the NOI available to the equity investor after applying leverage. This is exactly why both metrics are needed.
Use cap rate to compare properties independent of how each deal is financed. Use cash-on-cash to evaluate what each deal actually returns on your specific down payment and loan terms. A property with a lower cap rate but better financing can outperform on cash-on-cash in year one.
Rising rates compress cash-on-cash return directly by increasing annual debt service. They also push cap rates higher over time because buyers pay less for properties when financing costs rise. A deal that produced positive cash-on-cash at 4.5% rates may be breakeven or negative at 7% on the same purchase price.
