Laundromat ROI and Cash-on-Cash Return: Doing the Math Correctly

The Four Numbers That Get Skipped

Most laundromat return calculations you will encounter omit at least two of these:

Fix all four and you get a number you can compare against an index fund, a rental property, or a salaried job — which is the whole point of computing it.

Step 1: Total Cash In

Illustrative figures on a $250,000 store. Note that the down payment is barely a third of the total.

Step 2: Cash Flow, Properly Computed

If you intend to work in the store full-time, you can legitimately treat the $34,000 as income to yourself and not a cost — but then say so, and report both numbers rather than one.

Step 3: The Ratios

Three defensible cash-on-cash figures for the same store, ranging from 14% to 41%. Any of them can be quoted honestly if the assumptions are stated. Quoting the 41% without saying it includes your own wages is how listings work; it is not how underwriting works.

The DSCR line is the one a lender computes, and they compute it after striking any add-back without a source document. Test what your coverage does when $9,000 of add-backs disappear.

How Does an Advertised 30% Become 14%?

Most listings quoting a large return are not lying. They are dividing the wrong numerator by the wrong denominator, and both errors push in the same direction.

Take the store above. The advertised version divides normalized SDE of $96,000 by the $250,000 purchase price and reports 38%. Every step from there to the real figure is a correction, not a haircut.

The first correction is your labor. If the seller worked the store and you will too, that work has a market value, and $96,000 is a return plus a job, not a return. Valuing it at $34,000 leaves $62,000, and the reported figure falls to 25%.

The second is debt service. A financed buyer does not keep the whole $62,000, because the loan payment comes out before anything reaches them. At $33,600 a year, $28,400 remains.

The third is the replacement reserve. Machines wear out on a schedule, and a store that reports cash it will have to spend on a water heater in three years is reporting borrowed money. Setting aside $10,000 a year leaves $18,400.

The fourth correction is the denominator, and it is the one buyers miss most often. You did not invest $250,000 and you did not invest the down payment either. You invested every dollar that left your account to make the store yours — injection, closing costs, the valuation, working capital, the repair reserve, the capex the inspection flagged, and the transition costs. That is $128,300.

Eighteen thousand four hundred dollars against $128,300 is 14.3%. The advertised 38% and the honest 14.3% describe the same store in the same year. Nothing was hidden and no number was disputed. The gap is entirely in what each calculation chose to count.

What Should You Replace in That Example?

Three cells, and the rest of the method transfers unchanged.

Debt service is a placeholder. Your payment depends on the amount financed, the term, and the rate your lender actually quotes, and nobody can tell you those in advance. Get a real quote and use the real payment — solving the deal against a payment you were told rather than one you assumed is the single most common modelling error in a first acquisition.

The value of your own labor is local and personal. Price it at what it would cost to hire someone to do exactly the hours you intend to work, at your market's wage. If you plan to be genuinely absentee, price a manager instead, because that cost is real whether or not you have hired them yet.

The replacement reserve comes from the equipment schedule, not from a rule of thumb. Build the list of machines with install years, work out when each wave falls due, and divide the cost of the next wave by the years until it lands.

Everything else — the structure of the calculation, the order of the deductions, the insistence on total cash in — is the same at every store and every price.

Does Leverage Actually Improve the Return?

Less than most buyers assume, and the arithmetic is worth grasping before you decide how much to borrow.

Leverage raises cash-on-cash return only when the property's unlevered yield exceeds the loan constant. The unlevered yield is what the store returns with no debt at all: distributable cash flow divided by the full cash purchase price plus every acquisition cost. The loan constant is the annual debt service divided by the loan amount — not the interest rate, because it includes principal repayment too.

When the yield is above the constant, borrowed money earns more than it costs, and the surplus accrues to your smaller equity stake. When the constant is above the yield, every borrowed dollar dilutes the return rather than amplifying it.

At the terms most laundromat acquisitions are financed on, those two numbers land close together. A ten-year amortization pushes the constant well above the interest rate, because you are repaying principal quickly. That repayment is not lost — it builds equity, and it shows up in the exit, not in the annual cash flow — but it does mean the year-one cash-on-cash figure often improves only modestly with leverage, and sometimes not at all.

This changes what leverage is actually for in this asset class. It is not primarily an amplifier. It is access: the ability to control a $250,000 business with a fraction of the cash, and to keep the rest of your capital liquid for the reserve, the first bad quarter, and the second store. Those are good reasons to borrow. Expecting the loan to double your return is not.

Compute both numbers before you decide. If the constant exceeds the yield, borrowing still makes sense for access — but you should know that you are trading current cash flow for optionality rather than buying a higher return.

Step 4: The Exit

Cash-on-cash ignores the resale, which for a laundromat is a large part of the return. IRR captures it.

The trap: exit value depends on the same drivers as entry value, and one of them decays while you hold. A store bought with eleven controllable lease years and held five years is sold with six — which is below the ten-year benchmark a financed buyer needs, and the multiple moves accordingly.

The single largest lever in that table is not the earnings — it is whether the lease was extended during the hold. That is an argument for negotiating lease term as an owner, not just as a buyer.

Comparing Against the Alternatives

A return figure only means something next to something else. Compare like with like:

Two honest observations from that table. The leverage available on a laundromat is unusually high, which is a genuine structural advantage — 10% down on an operating business is not available in most asset classes. And the liquidity is poor: 139 days is the median time to an accepted offer, before diligence and financing.

The excess return over a passive alternative is compensation for the work, the concentration, and the illiquidity. That is a reasonable trade for many buyers. It is not a free lunch, and a model that shows a laundromat beating an index fund on a risk-adjusted, labor-adjusted basis has probably left something out.

Sensitivity: What Breaks the Model

Run these before you sign, using the store's own fixed-cost structure:

Because rent and much of the utility base are fixed, laundromat margin is highly sensitive in both directions. That is what makes the upside real when revenue grows, and it is why the downside case deserves as much attention as the base case.

What Actually Moves the Return

1. Price paid. The multiple you pay is the return you give away.
2. Lease term at entry and at exit. It decides both the multiple you pay and the multiple you get.
3. Documentation quality. It decides the multiple, the financing, and the resale.
4. How much of the work you do. Delegation is real cash out.
5. Utility cost trajectory. Utilities were the most-cited operator problem at 53% of survey respondents, and rate increases do not pause.
6. Equipment timing. A retool inside your hold period changes everything; one after your exit changes nothing for you.

What Should You Do Next?

Build the model with all four omitted items included, then run it again at a 10% and a 20% revenue decline. If the store still services its debt in the downside case, you have a margin of safety. If it does not, the return figure in the good case is not the number that matters.
