Cash-on-Cash Return: Levered vs. Unlevered, and the 2026 Negative-Leverage Reality
Key Takeaways
- Cash-on-cash is the levered current yield on equity: (NOI − debt service) ÷ equity. The unlevered version equals the going-in cap rate when total project cost equals the purchase price; the levered version diverges from it by the leverage wedge.
- The loan constant matters more than the coupon. A 5.5% rate fully-amortizing 30-year loan carries a ~6.8% constant; the same coupon interest-only is 5.5%. Leverage spread = loan constant − cap rate. Compare constant to cap rate, not coupon to cap rate, to size the wedge.
- At a 6.75% interest-only coupon (an illustrative 2026 assumption), the wedge is negative. The same $50M property at a 5.0% cap and 65% LTV produces 7.8% CoC at a 3.5% coupon and 1.8% at 6.75%, a compression of about 6 points driven entirely by debt cost.
- A rule-of-thumb 8–12% cash-on-cash target is unreachable at these inputs: at a 5.0% cap and a 6.75% interest-only coupon, no LTV produces more than 5.0%. Year-one CoC is 2.4% at 60% LTV, 3.3% at 50% LTV and 3.8% at 40% LTV.
- Never quote cash-on-cash alone. Pair it with IRR, MOIC, and LTV: the same 6% CoC at 50% versus 75% LTV describes two very different deals.
The Levered Yield on Equity
Cash-on-cash return is the simplest of the institutional return metrics. It measures the current-period yield on equity: cash flow after debt service divided by the equity check. A 6% cash-on-cash means $1 of equity is producing 6 cents of distributable cash per year. The math takes one line. The interpretation takes the rest of this article, because the number a deal produces depends entirely on the capital structure underneath it.
Two facts about cash-on-cash that determine everything else:
It is the levered counterpart of cap rate. The unlevered version of cash-on-cash, total property cash flow divided by total project cost with no debt, equals the going-in cap rate at acquisition when project cost equals the purchase price; closing costs and immediate capex push it modestly lower. Cap rate and cash-on-cash live in the same algebra. The difference between the levered and unlevered version is positive or negative leverage, and that wedge is the most important thing to understand about the metric.
At a high coupon, that wedge is negative. When the loan constant exceeds the cap rate, as in the 6.75% interest-only case used throughout this article, leverage drags cash-on-cash below the cap rate rather than amplifying it above. The rule-of-thumb 8–12% cash-on-cash target is unreachable on a 5.0% cap property at that coupon at any LTV. The honest benchmark depends on the cap rate, LTV and coupon of the underwriting. This article makes those inputs explicit.
THE 30-SECOND VERSION
Cash-on-cash = (NOI − debt service) ÷ equity invested. Unlevered cash-on-cash equals the cap rate when cost equals price; levered cash-on-cash adds the leverage wedge. When the loan constant exceeds the cap rate that wedge is negative: a 5% cap deal financed at a 6.75% interest-only coupon and 65% LTV produces levered cash-on-cash of 1.8%, below the cap rate. Pair cash-on-cash with IRR and MOIC; never quote alone.
The Formula
THE CASH-ON-CASH FORMULA
Cash-on-Cash = Before-Tax Cash Flow ÷ Total Equity Invested
Before-tax cash flow is annual NOI minus annual debt service (interest plus principal, if amortizing). Treatment of replacement reserves varies: state whether NOI is before or after reserves, and use the same basis for cash-on-cash and cap rate. Total equity invested is the all-in equity check (purchase price + acquisition costs + immediate-need CapEx − loan proceeds). The result is a single-period yield, typically quoted as a percentage.
Three variants matter:
Annualized cash-on-cash. The standard form: trailing-twelve or projected annual cash flow over equity. Most deal memos use the projected year-one number.
Average annual cash-on-cash. Average of the year-by-year cash-on-cash across the hold period. Smooths out a deal where year-one CoC is low (early-stage value-add) but stabilizes higher in years 3–5.
Stabilized cash-on-cash. Cash-on-cash computed on stabilized NOI rather than in-place NOI. For a value-add deal, this is what the property produces after the business plan is executed, the target the underwriting was built around. Use this for comparison to core deals.
Worked Example: $50M Multifamily
A 200-unit garden-style multifamily acquisition. $50M purchase price. $2.5M of stabilized NOI (5.0% going-in cap rate). 65% LTV agency debt at an illustrative 6.75% interest-only coupon: $32.5M loan, $17.5M equity check, annual debt service of $2,193.75K. Five-year hold with NOI growing 5% a year (an illustrative assumption) against static interest-only debt service. The example ignores closing costs and capex for clarity, so equity is the price minus the loan. The cash flow sequence to equity:
The deal opens at 1.8% levered cash-on-cash, 325 bps below the 5.0% going-in cap rate. That gap is the negative leverage produced by a 6.75% interest-only loan constant, 175 bps above the cap rate (the CoC gap is the spread times LTV ÷ (1 − LTV): 1.75% × 1.857 = 3.25%). NOI growth lifts cash-on-cash to 4.8% by year five, but leverage does not turn positive within the hold: the NOI yield on the $50M price reaches 6.08% in year five, still below the 6.75% constant (it would cross only when NOI exceeds $3.375M). If the same loan instead amortized over 30 years, debt service would be about $2.53M, the constant 7.78%, and year-one CoC about −0.2%. Quoted at acquisition, the headline number is 1.8%, not 5.0%.
Levered vs. Unlevered (And Why Unlevered = Cap Rate)
Unlevered cash-on-cash = NOI ÷ total project cost. For the worked example, ignoring closing costs and capex: $2.5M ÷ $50M = 5.0%. That equals the going-in cap rate. The two metrics are algebraically identical when you remove debt from the equation and total cost equals the purchase price; with acquisition costs and immediate capex in the denominator, unlevered cash-on-cash (a yield on cost) comes in modestly lower. This isn't a coincidence: cap rate is the unlevered yield on a property, and cash-on-cash is the same yield with debt service netted out and equity in the denominator instead of total cost.
Levered cash-on-cash = (NOI − debt service) ÷ equity. The levered version diverges from cap rate by the amount of the leverage wedge. The wedge is positive (levered CoC > cap rate) when the cap rate exceeds the loan constant; negative (levered CoC < cap rate) when the loan constant exceeds the cap rate; zero when they're equal.
The loan constant matters more than the interest rate. Loan constant = annual debt service ÷ loan balance, which for an amortizing loan includes both interest and principal. A 5.5% rate on a 30-year amortizing loan produces a loan constant of approximately 6.8%; the same rate on an interest-only loan produces a loan constant of 5.5%. At the illustrative 6.75% interest-only coupon used in this article, the constant is 6.75%, 175 bps above a 5.0% cap rate, so leverage is negative at acquisition and the deal depends on NOI growth to lift equity yield.
Define the leverage spread as loan constant minus cap rate; a positive spread is negative leverage (some sources define the spread with the opposite sign). Levered cash-on-cash minus cap rate equals −spread × LTV ÷ (1 − LTV). At 65% LTV on a 5.0% cap: a 6.75% interest-only constant gives a spread of +175 bps and a CoC gap of −325 bps (1.75% vs 5.0%); a 5.5% interest-only constant gives +50 bps and −93 bps (4.07% vs 5.0%); a 5.5% 30-year amortizing loan (constant 6.81%) gives +181 bps and −337 bps (1.63% vs 5.0%).
The 2026 Negative-Leverage Reality
The clearest way to see the effect of the debt market on cash-on-cash is to hold the property constant and vary the coupon. Same $50M multifamily, same 5.0% cap rate, same 65% LTV interest-only debt, financed at three illustrative coupons (assumptions, not market quotes) along the post-2020 rate path:
A 325 bps higher coupon (3.50% to 6.75%) has cut levered cash-on-cash from 7.8% to 1.8% on the same property, same NOI, same LTV. A rule-of-thumb 8–12% cash-on-cash target ignores this. At a 5.0% cap rate and a 6.75% interest-only coupon, levered cash-on-cash is (5.0% − LTV × 6.75%) ÷ (1 − LTV), which never exceeds 5.0% at any LTV. Cash-on-cash at acquisition reaches higher numbers only through value-add NOI growth, a higher going-in cap rate, a lower coupon, or lower LTV (which pulls cash-on-cash up by reducing the leverage drag, at the cost of a larger equity check).
Negative leverage is the situation where unlevered cash-on-cash exceeds levered cash-on-cash;Wall Street Prep's negative leverage explainerdefines it the same way. Whether it describes a given acquisition depends on the loan constant and cap rate in that deal. The implication for cash-on-cash targeting is direct: don't underwrite to a fixed CoC number; underwrite to the spread between loan constant and cap rate and let the CoC fall out.
What's a Good CoC Today?
"Good" depends on capital structure as much as on the asset itself. Year-one cash-on-cash falls out of the cap rate, the LTV and the coupon. The table below holds the cap rate at 5.0% (an illustrative assumption) and varies LTV and interest-only coupon, using CoC = (cap rate − LTV × coupon) ÷ (1 − LTV) and ignoring closing costs and capex:
| Leverage (5.0% cap rate) | 3.5% IO coupon | 5.5% IO coupon | 6.75% IO coupon |
|---|---|---|---|
| All-cash / unlevered | 5.00% | 5.00% | 5.00% |
| 40% LTV | 6.00% | 4.67% | 3.83% |
| 50% LTV | 6.50% | 4.50% | 3.25% |
| 60% LTV | 7.25% | 4.25% | 2.38% |
| 65% LTV | 7.79% | 4.07% | 1.75% |
Year-one cash-on-cash on a value-add deal sits below these figures during the renovation; the deal underwrites on the stabilized year-three-plus number. For other property types, substitute that asset's going-in cap rate in the formula.
No cell in the table reaches 8%. When you see an 8% cash-on-cash quoted at acquisition on a stabilized deal, check the loan terms and the NOI basis: the usual explanations are a higher going-in cap rate than 5.0%, a lower coupon, low leverage, or reliance on stabilized rather than going-in NOI.
Five Mistakes Practitioners Make
Quoting year-one cash-on-cash on a value-add deal. A value-add property has depressed year-one cash flow during the renovation. Quoting year-one CoC in isolation makes the deal look broken when it's just under-construction. Quote the stabilized year-three or year-four CoC alongside, or the average-annual CoC across the hold.
Ignoring the loan constant. Interest rate alone doesn't determine leverage drag; loan constant does. A 5.5% rate on a 30-year amortizing loan has loan constant ~6.8%; the same rate IO is 5.5%. On a 5.0% cap deal, the first is negative leverage (a spread of ~181 bps); the second is smaller negative leverage (50 bps). When underwriting, compare loan constant to cap rate, not coupon to cap rate.
Conflating cash-on-cash with cap rate. They're related (unlevered CoC = cap rate) but not the same. When debt enters the picture, levered CoC and cap rate diverge by the leverage wedge. Practitioners sometimes quote "CoC of 5.0%" when they mean cap rate, or vice versa. Be explicit about which.
Quoting CoC without stating LTV. A 6% CoC at 50% LTV is a very different deal than a 6% CoC at 75% LTV. Same yield on equity, but the higher-LTV deal has a larger debt service obligation, more refinance risk, and less equity cushion. Always disclose the leverage when quoting CoC.
Treating CoC as the complete return picture. Cash-on-cash is current-period yield. It says nothing about appreciation, depreciation tax benefits, or the eventual sale proceeds. In an illustrative case, $100 of equity that pays $3 a year and returns $150 at sale in year five (3% CoC) has an IRR of 11.0%, while $100 that pays $8 a year and returns $100 at sale (8% CoC, flat value) has an IRR of 8.0%. Quote CoC alongside IRR and MOIC, not in isolation.
The 2021-Vintage CoC Refresh
Consider a 2021 acquisition of the same $50M property at 65% LTV, financed with a floating-rate interest-only bridge loan at SOFR + 250 bps with no index floor. SOFR averaged about 0.04% in 2021 and sat between 5.30% and 5.40% from August 2023 through February 2024 (FRED SOFR series). At 0.04% SOFR the all-in coupon is 2.54% and year-one CoC is ($2,500K − $825.5K) ÷ $17,500K = 9.6%. At 5.30% SOFR the all-in coupon is 7.80%, debt service is $2,535K, and CoC is −0.2%, before any rate cap or hedge. Debt service roughly tripled (7.80% ÷ 2.54% = 3.07x). Refinancing into fixed-rate debt at a coupon like the 6.75% used above would lock in a year-one CoC of 1.8% at 65% LTV for the remaining hold, if NOI is unchanged.
For LPs holding 2021 commitments, the realistic conversation is no longer "is my deal returning the underwritten CoC?" but "what is my CoC trajectory now, given the take-out debt I'm refinancing into?" The math is straightforward when the cash flows are visible: update the debt cost, re-amortize the static portion, recompute the BTCF. In the example above, the original 9.6% does not survive the refresh.
How to Model CoC in Excel
Cash-on-cash is the easiest of the return metrics to model. Five rows:
1. NOI by year. From the underwriting cash flow tab. For each year of the hold, take that year's NOI.
2. Debt service by year. If interest-only, this is loan balance times rate. If amortizing, use Excel's
=-PMT(rate/12, term*12, loan_balance) * 12to get annual debt service (PMT returns a negative number, so the leading minus sign makes the result positive). For a refi mid-hold, switch the debt service row at the refi year.3. BTCF = NOI − debt service.
4. Equity check. A single cell with the all-in equity at acquisition.
5. Cash-on-cash = BTCF / equity check, formatted as percentage. One value per hold year. Use one more cell for the average-annual CoC:
=AVERAGE(coc_row).
The model takes ten minutes to build from scratch. The harder work is building the NOI projection that the CoC is computed on: rent roll, vacancy curve, operating expenses, replacement reserves, capex schedule. None of that fits in five rows.

FAQ
Frequently Asked Questions
What is cash-on-cash return?
Cash-on-cash return is the ratio of annual before-tax cash flow to total equity invested in a real estate deal. It's the current-period yield on equity. A 6% cash-on-cash means $1 of equity produces 6 cents of distributable cash per year. The standard formula is (NOI − debt service) ÷ equity invested.
How do you calculate cash-on-cash return?
Take annual NOI, subtract annual debt service, and divide by total equity invested (purchase price plus closing costs plus immediate CapEx minus loan proceeds). The result is a percentage. For a $50M property with $2.5M NOI, $2,193.75K of interest-only debt service (6.75% on a $32.5M loan), and $17.5M equity (ignoring closing costs and CapEx): ($2,500K − $2,193.75K) ÷ $17,500K = 1.75%, or about 1.8% cash-on-cash.
What's the difference between cash-on-cash and cap rate?
Unlevered cash-on-cash equals the cap rate at acquisition when total project cost equals the purchase price (NOI ÷ price); closing costs and CapEx lower it modestly. Levered cash-on-cash adds debt: NOI minus debt service, divided by equity instead of total cost. When the loan constant equals the cap rate, levered and unlevered CoC are equal (when total project cost equals the purchase price). When the loan constant exceeds the cap rate (for example a 6.75% interest-only loan on a 5.0% cap), levered CoC falls below the cap rate. When the cap rate exceeds the loan constant (for example a 3.5% interest-only loan on a 5.0% cap), levered CoC exceeds the cap rate.
What's a good cash-on-cash return in 2026?
It depends on the cap rate, LTV and coupon. At a 5.0% cap rate and 65% LTV with interest-only debt, year-one cash-on-cash is 7.79% at a 3.5% coupon, 4.07% at 5.5% and 1.75% at 6.75%. At 60% LTV and a 6.75% coupon it is 2.38%. At a 6.75% coupon no LTV produces more than the 5.0% cap rate. Value-add deals sit below these figures in year one and are underwritten on the stabilized number. A rule-of-thumb 8–12% target is not reachable at these inputs.
What is negative leverage in real estate?
Negative leverage occurs when the loan constant (annual debt service ÷ loan balance) exceeds the property's cap rate. In this regime, financing the property with debt drags the levered cash-on-cash return below what an unlevered owner would receive. Whether a given deal is in this regime depends on its own loan constant and cap rate: at a 5.0% cap rate, any interest-only coupon above 5.0% produces negative leverage. Positive leverage is the opposite case, where the cap rate exceeds the loan constant.
What's the difference between levered and unlevered cash-on-cash?
Unlevered cash-on-cash uses total property cash flow (NOI without debt service) divided by total project cost, which equals the cap rate at acquisition when cost equals the purchase price. Levered cash-on-cash uses cash flow after debt service divided by the equity check. The two diverge by the leverage wedge: positive when cap rate > loan constant, negative when loan constant > cap rate.
Does cash-on-cash include the sale at exit?
No. Cash-on-cash is a current-period (annual) yield metric. It excludes appreciation, sale proceeds, and any back-end value creation. For total return, pair cash-on-cash with IRR (time-weighted) and equity multiple / MOIC (absolute-dollar) to get the full picture.
Why did cash-on-cash drop so much from 2021 to 2026?
In the illustrative example the coupon rises from 3.5% to 6.75% (about 1.9x) while the cap rate is held constant at 5.0% to isolate the effect. A $50M property at a 5.0% cap rate, 65% LTV, interest-only debt: a 3.5% coupon produces 7.8% levered CoC; a 6.75% coupon produces 1.8%, a compression of about 6 points driven entirely by debt cost. The gap between the loan constant and the cap rate flipped from negative to positive. The property hasn't changed; the financing has.
How is cash-on-cash different from ROI?
Cash-on-cash measures annual current yield on equity. ROI is a total return metric that includes appreciation and the eventual sale. A deal with 4% CoC and 10% appreciation per year has higher total ROI than its CoC suggests. Cash-on-cash is the periodic income return; ROI is the comprehensive return including capital appreciation.
