The Number LPs Ask About First
A sponsor pitches a $22M multifamily deal at a 5.1% going-in cap rate. The first thing the LP on the other end of the call asks is what the property distributes on their equity check in year one. That number, cash on cash return, determines whether the deal clears an investor’s minimum current-yield hurdle before anyone talks about exit assumptions or terminal value.
Cash on cash return measures the annual pre-tax cash flow an investor receives relative to the actual equity they put into the deal. It answers a practical question: how much cash lands in my account this year, for every dollar I invested? Unlike cap rate, which ignores financing entirely, cash on cash return is a levered metric that reflects the real capital structure of the deal, debt included. That makes it the number most LPs check first, because it tells them what the investment pays.
The Formula
Cash on cash return is calculated as:
Cash on Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
Two components require precision:
Annual pre-tax cash flow is net operating income (NOI) minus annual debt service (principal and interest). NOI alone would give you the unlevered yield, which is the cap rate. And it is not cash flow after capital expenditures unless the investor explicitly wants an after-capex figure, which more sophisticated underwriting increasingly requires. For a full breakdown of how NOI itself is built from a rent roll and operating statement, see our NOI guide.
Total cash invested is the actual equity contributed at closing: the down payment, closing costs, and any upfront capital reserve, minus any equity returned through a subsequent refinance (a nuance covered below). Using purchase price instead is the most common cash on cash calculation error among newer analysts.
Worked Example: $18M Value-Add Multifamily Acquisition
Consider an institutional buyer acquiring a 180-unit multifamily property for $18,400,000.
Capital stack:
- Purchase price: $18,400,000
- Acquisition and closing costs: $310,000
- Loan proceeds (65% LTV, 6.1% fixed rate, 30-year amortization): $11,960,000
- Total equity invested: $6,750,000
Year one operations:
- Gross potential rent: $2,890,000
- Vacancy and concession loss (7%): ($202,300)
- Other income (parking, pet fees, RUBS): $184,000
- Effective gross income: $2,871,700
- Operating expenses (taxes, insurance, payroll, R&M, utilities): $1,148,700
- NOI: $1,723,000
Debt service:
- Annual principal and interest on the $11,960,000 loan: $872,400
Year one pre-tax cash flow: $1,723,000 − $872,400 = $850,600
Cash on cash return: $850,600 ÷ $6,750,000 = 12.6%
Compare that to the unlevered yield on the same deal — the going-in cap rate:
$1,723,000 ÷ $18,400,000 = 9.4%
The 320-basis-point spread between the cap rate and the cash on cash return is the leverage effect: because the loan’s interest rate (6.1%) is lower than the property’s cap rate (9.4%), debt is accretive, and the levered return exceeds the unlevered return. This is positive leverage, and it is the mechanism that makes cash on cash return higher than cap rate in most institutional deals financed below current market cap rates. Reverse that spread by borrowing at a rate above the cap rate, and cash on cash return falls below the unlevered yield instead. For the mechanics of how a lender sizes that loan against the same NOI figure, our DSCR calculator walks through the constraint that often caps leverage before LTV does.
Cash on Cash Return vs. Cap Rate vs. IRR
Each metric answers a different question, and they are not interchangeable.
| Metric | What it measures | Accounts for leverage | Accounts for time/exit | Best used for |
|---|---|---|---|---|
| Cap Rate | Unlevered yield on purchase price | No | No | Comparing asset pricing across a market |
| Cash on Cash Return | Levered current yield on invested equity | Yes | No (single period) | Assessing annual distribution income for LPs |
| IRR | Time-weighted total return including exit | Yes | Yes | Comparing full-hold total return across deals |
| Equity Multiple | Total dollars returned per dollar invested | Yes | Partial (no time-weighting) | Sanity-checking IRR against absolute dollars |
Cap rate strips out financing to let buyers compare properties on a level, asset-only basis — useful for underwriting a market, less useful for underwriting a specific investor’s return. Our cap rate guide covers that mechanic in depth. Cash on cash return brings financing back in but stays confined to a single year, which makes it excellent for evaluating current income but blind to what happens at sale. IRR closes that gap by time-weighting every cash flow across the hold period, including the terminal sale — see our DCF guide for how that full projection gets built.
A deal can show a strong cash on cash return in year one and still deliver a mediocre IRR if the exit cap rate expands or the hold period underperforms on rent growth. Conversely, a deal with a modest first-year cash on cash return can post a strong IRR if the value-add business plan compresses the exit cap rate meaningfully below the entry cap rate. No single metric substitutes for the others; institutional underwriting memos report all three side by side, not one in isolation.
When Cash on Cash Return Misleads
Capital expenditure reserves. The formula above uses NOI minus debt service; it does not deduct capital reserves for roof replacement, HVAC turnover, or unit renovations. A property showing a 12.6% cash on cash return before capex reserves might show 9-10% after setting aside a realistic reserve. Sponsors who omit capex reserves from their cash on cash presentation are showing LPs a number the property will not actually distribute once maintenance capital gets funded. Always ask whether the quoted figure is gross or net of reserves, and model both.
Cash-out refinance distortion. Cash on cash return is a ratio, and ratios can be manipulated by shrinking the denominator. If a sponsor refinances two years into the hold and pulls out $2M in equity, the remaining invested capital drops from $6.75M to $4.75M. If distributions stay roughly flat at $850,000, the reported cash on cash return jumps from 12.6% to nearly 18% because less capital remains at risk, not because the property performs better. This is a legitimate outcome for the LP (their basis has genuinely dropped), but it should always be reported against original invested equity as well, so investors can see the underlying operating performance without the leverage-event distortion.
Interest-only periods. A loan with an interest-only period in years one and two will show an inflated cash on cash return during that window because principal is not being amortized. Once amortization begins, cash flow drops and the reported cash on cash return falls with it, even if NOI has grown. Underwriting memos should show the cash on cash return trajectory across the full hold, not just a stabilized-year snapshot cherry-picked from the interest-only period.
Below-market debt assumptions. Sponsors modeling refinance-driven leverage benefits sometimes assume future debt terms more favorable than what the market is currently pricing. A cash on cash projection that depends on a rate assumption two points below current spreads should be flagged and stress-tested against a flat-rate scenario before it factors into an investment decision.
Cash on Cash Return Across the Hold Period
A single-year cash on cash return snapshot understates how much the metric moves over a typical five-to-seven-year hold. Continuing the $18.4M multifamily example, project the same deal through a value-add renovation program:
Year one (pre-renovation, stabilized-in-place rents): NOI of $1,723,000 against debt service of $872,400 produces the $850,600 cash flow and 12.6% cash on cash return calculated above.
Year two (renovation disruption): As units are taken offline for renovation, occupancy dips to roughly 89% and NOI temporarily falls to $1,540,000. Debt service is unchanged. Cash flow drops to $667,600, and cash on cash return falls to 9.9%, a normal trough during an active repositioning, not a sign the deal is underperforming its business plan.
Year four (stabilized post-renovation): With renovated units re-leased at a $185/month premium across 130 of the 180 units, NOI climbs to $2,050,000. Cash flow rises to $1,177,600, and cash on cash return reaches 17.4%.
This trajectory of a dip followed by a step-up is typical of value-add multifamily and industrial repositioning deals, and it is exactly why a single stabilized-year cash on cash figure quoted in a marketing deck can misrepresent what an investor actually experiences during the early years of the hold. Institutional underwriting should present the full year-by-year cash on cash schedule, not just the terminal stabilized number, so LPs can evaluate the actual cash flow timing against their own liquidity needs. The annual return figure is simply one line pulled from a multi-year projection that also needs realistic assumptions for renovation downtime, lease-up pace, and rent growth.
How Lenders and Buyers Use Cash on Cash Return Differently
Equity investors use cash on cash return to evaluate distribution income against their invested capital. Lenders generally do not use the metric at all — their underwriting runs through debt service coverage ratio, which measures NOI against debt service directly rather than net cash flow against equity. The two metrics are related (both start from NOI and debt service) but answer different questions for different parties: DSCR tells a lender whether the property generates enough income to safely cover the loan payment with a cushion; cash on cash return tells an equity investor what’s left over for them after that payment is made. A deal can carry a healthy 1.35x DSCR that a lender is comfortable with while still producing a thin cash on cash return for equity, if the purchase price leaves a small equity check relative to the leverage. Reviewing both figures together, rather than treating them as substitutes, is standard practice in institutional commercial real estate loan underwriting.
Building Cash on Cash Return Into the Underwriting Process
Cash on cash return is only as reliable as the NOI and debt assumptions feeding it, which means it lives downstream of the rent roll, T-12, and loan term sheet rather than independent of them. Errors in any of those source documents propagate directly into the calculated return. Platforms like Moraine extract NOI, rent roll, and T-12 data directly from source documents into a linked underwriting model, so the cash on cash figure a sponsor presents traces back to the actual lease and financial statement line items rather than a manually re-typed summary tab.
Run the calculation with both gross and capex-adjusted cash flow, check it against original (not refinanced) equity, and always present it next to cap rate and IRR rather than in isolation. Use the cash on cash calculator to run the numbers on a specific deal, and cross-check the debt assumptions with the DSCR calculator before finalizing the capital stack.
