Laundromat Valuation Calculator

By Jason Taken, business broker · HedgeStone Business Advisors · Updated 2026-09-24 · 10 min read

Model assumptions: The seven factor weights and 8% replacement-cost discount rate are editorial scenario choices, not coefficients estimated from transaction data. Published sale quartiles describe a reported sample; they are not a confidence interval or an appraisal of this store.

How Does the Calculation Work?

Step 1 — Normalize. Net income from the filed return, plus one working owner's compensation and payroll taxes, plus depreciation, plus interest, plus documented personal expenses, plus genuinely non-recurring items. That is seller's discretionary earnings.

The calculator deliberately gives you one owner-compensation field rather than several. SDE is defined on the basis of a single working owner; if the store needs two people and a buyer will have to pay for the second, that cost stays in the expenses.

Step 2 — Place the multiple. It starts at the 3.50x median from 855 reported sales and moves on seven factor scores, each weighted by how much it actually changes a laundromat deal:

The result is clamped to the 2.72x-4.50x quartile range, because the calculator should not produce a multiple the market has not paid.

Step 3 — Subtract the capital program. The installed cost of the replacement you expect to fund, discounted at 8% to the year you expect to fund it. This is why equipment reduces value rather than adding to it: an earnings multiple already prices the assets producing the earnings.

Step 4 — Cross-check. The implied revenue multiple is compared against the 0.93x-1.64x quartile range from the same dataset. A result far outside that band usually means a normalization error, not an unusual store.

What the Inputs Mean

Net income should come from the filed federal return. Using a bookkeeping P&L that includes personal spending, or excludes it inconsistently, is the most common way this calculation goes wrong.

Add-backs each need a source document. A payroll record for the compensation. A mileage log and registration for the vehicle. An invoice for the one-time legal fee. Every add-back a buyer's lender strikes reduces the price by its amount times the multiple — roughly $3.50 of price for every dollar struck at the median.

Do not add back ordinary repairs, routine cleaning, card-processing fees, insurance, family labor a buyer must replace, or deferred maintenance. And unreported cash is not an add-back at all: buyers pay for what they can prove and lenders underwrite documented cash flow.

The replacement program should come from an installed distributor quote, not a machine sticker price. Installed means freight, rigging, demolition and disposal, pads and bases, plumbing and drains, gas, electrical, venting, permits, payment hardware, and downtime. Public market guides currently place many commercial washers around $3,500-$15,000 per unit and stacked dryers around $6,000-$12,000 per cabinet before any site work, with medium 25-40 machine packages often described around $100,000-$300,000. Those are secondary-source planning ranges for framing a conversation, not quotes for a transaction.

What This Calculator Cannot Tell You

• Whether your revenue is documentable. It takes your earnings figure at face value. A lender will not.
• Whether the lease survives a buyer's loan. The factor score is a proxy; the clause language is the reality, including who controls the options and whether the landlord can recapture the premises on assignment.
• What a specific machine is about to cost you. Only an inspection and a quote establish that.
• What the market in your trade area is doing. New competing capacity two blocks away does not appear in any input here.
• What a buyer will actually pay. The median asking price across the same dataset was $275,000 against a $250,000 median sale price, and 2025's sale-to-ask ratio was 0.91.

Which Input Deserves the Most Effort?

The earnings, by a wide margin — and most people spend their effort on the multiple instead.

The reason is arithmetic. The multiple moves within a fairly narrow band: the middle half of reported sales ran 2.72x to 4.50x (Source: BizBuySell, 2021-2025). Arguing a store from the middle of that range to the upper quartile is worth something and requires demonstrable facts about lease, documentation and equipment. There is a ceiling on how far the argument can go.

The earnings figure has no such ceiling, and it is where the errors are largest. An add-back schedule with several unsupported items can overstate earnings substantially, and because the error is then multiplied, it produces a valuation wrong by several times the original mistake. The same is true in reverse: an owner who has not identified legitimate add-backs is understating the number being multiplied.

There is a second reason to prioritise it. The earnings figure is the input a buyer, a lender and an appraiser will all independently recompute against documents. The multiple is a judgment they may argue about; the earnings are something they will test. An error there does not survive, and it damages confidence in everything else you presented.

So: normalise from filed returns, with a source document behind every adjustment, before touching the multiple.

What Should You Do When the Cross-Checks Disagree?

Treat the disagreement as the most useful output rather than as a problem to average away.

The methods — earnings multiple, revenue multiple, physical capacity, and what a lender would fund — will rarely agree exactly. A modest spread is normal and defines a range. A large spread means one of your inputs is wrong, and finding out which is worth more than any of the four answers.

Earnings multiple far above the revenue multiple means the margin is unusually high for the revenue. Either expenses are understated, an add-back is aggressive, or the store is genuinely efficient. All three are worth knowing; only one supports the price.

Physical capacity below the claimed revenue means the revenue claim is wrong. Machine count times realistic turns times vend price sets a ceiling, and a figure above it is arithmetically impossible whatever any document says. This check catches the largest errors.

A lender funding materially less than your indication means the practical value falls toward what a cash buyer will pay, because the financed pool has dropped out.

The wrong response to a wide spread is to take an average. Averaging four numbers where one rests on a bad input produces a figure that is wrong by a quarter of the error and looks reasonable — which is worse than an obviously wrong answer, because nobody investigates it.

How Should You Use the Result?

That depends on the decision in front of you, and using a valuation for the wrong purpose is a common and expensive error.

Deciding whether to sell. Compare net proceeds — after debt, transaction costs and tax — against what the store produces if you keep it, with the market cost of your own labour deducted from the keep case. Run honestly, this comparison often favours keeping, particularly for an owner who enjoys the work.

Setting an asking price. The output is the floor of the argument, not the number itself. Show the working: the earnings basis, the multiple and why it sits where it does, the capital deduction. A price with visible workings survives a buyer's challenge; one without them is treated as an opening position.

Planning an exit two or three years out. Here the most valuable output is not the number at all — it is the list of things suppressing it. Lease term, documentation quality, owner dependence. Those are what respond to effort, and this is the best moment to identify them.

A divorce, partnership separation or estate. This method is not the right instrument. Those settings have standards of value and valuation dates set by law or agreement, and they require a formal appraisal from a credentialed appraiser.

What Cannot This Method Do?

Four things, and knowing them prevents the output being used for a job it cannot do.

It cannot value a store with no earnings. A closed or failing business has nothing to multiply, and it must be valued on the assets in place — which is a different exercise with a different floor.

It cannot price a synergy. A neighbouring operator who can run your store with existing staff, or a portfolio buyer for whom it completes a cluster, may pay more than any general method indicates. That premium is specific to them and not available to every seller.

It cannot substitute for a formal appraisal. Divorce, partnership separation, estate and tax settings have standards of value and valuation dates set by law or agreement, and require a credentialed appraiser working to those standards.

It cannot tell you whether a buyer exists. A defensible number on a store with a short lease and unverifiable revenue is still a number nobody can finance. Value and marketability are different questions, and the second one is answered by the lease and the documentation, not by arithmetic.

Limits and Disclaimer

This tool produces an illustrative range for discussion. It is not an appraisal, not a broker opinion of value, and not legal, tax, or investment advice. Valuation outcomes depend on documents, the specific lease, the equipment's actual condition, local market conditions, and the buyer pool available at the time of sale. Nothing here guarantees a sale price or a financing outcome. Confirm tax treatment with your CPA and legal questions with your attorney.

What Should You Do Next?

Run the calculator, then do the two things that move the number more than any input on this page: read your lease and count how many independent sources document your revenue. If the answer to the second question is fewer than three, that is the highest-return work available to you.
