Writing a Laundromat Business Plan a Lender Will Read

Who Is It Actually For?

Three audiences, and they want different things from the same document.

A lender is asking one question: will this be repaid from the business rather than from the guaranty? They read the projections, test the assumptions, and look for the items that are commonly missing. Everything else is context.

You are the second audience and arguably the more important one. The exercise of building the numbers is where you discover whether the project works — and it is considerably cheaper to discover that in a spreadsheet than after signing a lease.

A landlord is occasionally the third, particularly for a build in a desirable space. They want to know the tenant will pay rent for the term.

Writing for the first audience produces a document that serves all three. Writing for none of them in particular produces the template output that underwriters read hundreds of, which is a document that describes the laundry industry rather than your store.

What Does an Underwriter Read First?

Not the executive summary. The projections, and then backwards from there into the assumptions.

Revenue, and how you got it. A figure with no derivation is an assertion. A figure built from machine count by capacity, realistic turns per day, and the vend prices you intend to charge is arithmetic that can be checked — and checkable is the whole point.

The cost base against known benchmarks. Utilities ran at a median 20% of gross revenue for surveyed owner-operators in 2023 (Source: CLA, 2024). A plan projecting materially better than that needs a reason, and "efficient new machines" is only half a reason unless you have your local water, sewer and gas rates in the model.

Debt service coverage, after a salary. Lenders commonly want 1.25 or better, computed after deducting a market-rate salary for whoever runs the store. Buyers omit that deduction from their own models constantly; underwriters never do.

Total project cost. Not the price. The price plus closing costs, working capital, reserves, near-term capital spending, and — for a build — rent through construction and permitting.

Your position. Injection sourced and seasoned, liquidity remaining after closing, credit, and relevant experience.

What Does an Underwriter Check, and Against What?

What Belongs in the Demand Case?

The part most plans handle worst, because it is where generic content substitutes for local work.

Industry description is not a demand case. That the Census counts 15,957 coin-operated laundries nationally (Source: U.S. Census Bureau, CBP 2023) tells a reader nothing about whether yours will have customers.

What does:

The population within a short drive, and specifically the renter share — households without in-unit laundry are the customer base, and the count of them is the ceiling on demand.

The competing supply serving those same households. Not a city-wide count. The stores in your radius, walked and assessed: how many machines, what condition, what hours, how busy at different times.

Utilisation of the incumbents. A competitor at capacity indicates unserved demand. Competitors sitting half-empty indicate a market that is already served, and no amount of a better store creates customers that are not there.

The site itself — visibility, parking, access with a basket, and the physical constraints of the building.

For an acquisition, this section is shorter and different: the store already has customers, so the demand case is about durability rather than existence.

Which Assumptions Get a Plan Sent Back?

Five, and they recur so consistently that an experienced underwriter checks for them specifically.

Profitability arriving implausibly fast. A new store opens at zero and earns customers one at a time. A plan reaching a mature revenue run-rate within a few months is describing a launch, not a ramp.

No ramp funding at all. The store owes rent, utilities, insurance, loan payments and any payroll in full from day one, and it has to cover your living costs. A plan that funds the build and not the gap has funded the easy half.

Owner labour valued at zero. If you will work in the store, that work has a market value, and a projection that omits it reports a return plus a job as though it were a return.

Utility costs from a template. Water, sewer and gas rates are local, and sewer is usually billed as a multiple of metered water. A plan using generic figures has guessed at the second-largest cost in the business.

A revenue figure above physical capacity. Machine count times realistic turns times vend price is an arithmetic ceiling. A projection above it is impossible, and this is the check that catches the largest errors.

How Should the Numbers Be Built?

From the bottom, in an order where the expensive discoveries happen early.

Start with the site's capacity, before any financial modelling. Water service size, sewer basis and any capacity charge, gas supply and meter, electrical service. Any of these can rule a space out or add a large number, and all are established by phone calls.

Then the machine list, derived from the trade area rather than a catalogue, and quoted by several distributors against the same specification.

Then revenue, built as machines by capacity times turns times price — with the turns assumption stated and justified from the demand work rather than assumed.

Then costs, using your own utility rates, your own quoted rent, and a loaded labour figure that includes employer taxes and insurance.

Then the ramp, modelled month by month, with the gap between opening and covering costs funded from cash that exists before you open.

Then a downside case. Revenue down 20%, or the ramp running twice as long as planned. A plan that survives its own downside is a plan; one that only works on the base case is a hope with a spreadsheet attached.

Does an Acquisition Need One?

Less than a build, and not nothing.

A lender financing an acquisition underwrites the store's filed returns, its lease, and your position — not your forecast. The evidence that matters is historical rather than projected, which is why buying is the more financeable route and why the document a buyer assembles is closer to a diligence file than a business plan.

What is still worth writing is short and specific: what you are buying, what it earns and how that is supported across independent sources, how many controllable lease years remain, what the equipment position implies for capital spending, and what you intend to do in the first year. That document is a page or two, it answers the questions an underwriter will ask, and it is far more persuasive than a templated plan wrapped around somebody else's numbers.

Summary

The parts of a business plan that get read are the projections and the assumptions underneath them. Build the numbers from your own site, your own distributor quotes and your own utility rates, derive revenue from machines and turns rather than asserting it, deduct a market-rate salary, and fund the ramp as well as the build.

Then test it against a downside. A plan is not a document that shows the project working — it is one that shows you know what would make it fail, and that the store survives that case anyway.
