29 valuation methods · 43 industries · Results in under 10 minutes

In short

A machine shop or contract manufacturer is valued on its earnings with the industrial manufacturing approach: a discounted cash flow, comparable companies and precedent transactions, with an asset floor underneath. Certifications, customer concentration and equipment shape what buyers pay.

Who this is for

Owners of CNC machining, fabrication, welding and contract manufacturing shops preparing to sell, bring in a partner or plan succession, and buyers who need certifications, customer concentration and equipment read with the earnings.

How is a machine shop valued?

VA values a machine shop or contract manufacturer with its industrial manufacturing approach: a discounted cash flow, comparable companies and precedent transactions, with an asset floor underneath so the result does not fall below what the company's own assets would recover. For a smaller company, precedent transactions carry the most weight. Earnings are taken after the add-backs you confirm. This tool is informational only. Output is driven by your inputs and does not constitute a formal appraisal or certified valuation.

What drives the value of a machine shop?

  • Certifications such as aerospace, medical and automotive quality standards
  • Customer concentration, and how long the largest customers have stayed
  • Equipment: the age of the machines and the spending they will need
  • Skilled machinists and programmers, and how long they stay
  • Work that is hard to move: tight tolerances, qualified parts, long relationships
  • Quoting and scheduling that run without the owner

What lowers the value of a machine shop?

  • One or two customers behind most of the revenue
  • Machines that need replacing soon
  • Quoting and customer relationships held by the owner
  • Skilled machinists who are hard to replace

How much is a machine shop worth? A worked example

A machine shop, by discounted cash flow

Take a machine shop with $6 M of revenue and a 15% EBITDA margin, or $900 K of EBITDA. Assume revenue grows 4% a year for five years, capital spending and depreciation each run at 4% of revenue, working capital takes 12% of each year's added revenue and tax is 25%. Cash flows are discounted at 18%, the lowest rate VA uses for a company this size, with 2.5% growth after year five. VA's discounted cash flow gives about $3.27 M before debt, or 3.6× EBITDA. At a 12% EBITDA margin, as when a large customer takes work in-house, it comes to about $2.32 M. In a full report for a company this size, precedent transactions carry the most weight.

Which numbers matter most?

Normalized EBITDA

EBITDA after the add-backs you confirm. Comparable companies and precedent transactions apply their multiples to it, and the discounted cash flow starts from it.

Top customer share

The part of revenue from the largest customer. Job shops often serve a few manufacturers, so buyers price concentration closely.

Machine age and utilization

How old the machines are and the hours they run. Spare capacity lets a buyer grow without new equipment; old machines mean spending soon.

On-time delivery and quality

Delivery and reject rates by customer. They keep the work and the certifications, and buyers check both.

What do you need to value a machine shop?

  • Profit and loss statements and balance sheets, ideally for the last three years
  • Figures for the current year to date
  • A list of add-backs: the owner's pay and perks, and any one-off costs
  • Loan and lease balances
  • Revenue by customer, with the certifications you hold
  • An equipment list with ages, hours and planned spending
  • On-time delivery and quality records by customer

Example scenarios

Losing part of a large customer's work

The largest customer moves part of its work in-house and the margin falls. The worked example shows what a lower margin does to the discounted cash flow.

An owner who quotes every job

The owner prices every job and knows every customer. The earnings count, but a buyer needs someone else able to quote and schedule, and may keep the owner on for a transition.

Frequently asked questions

How is a machine shop valued?

With the industrial manufacturing approach: a discounted cash flow, comparable companies and precedent transactions, with the value of its assets as a floor. For a smaller company, precedent transactions carry the most weight.

Do certifications raise the value?

They do not change the model's multiple, but buyers pay for them, because aerospace, medical and automotive work is hard to move once a shop is qualified.

Does the equipment count toward the value?

The model values the earnings the machines produce, and the asset floor keeps the result above what the company's own assets would recover. The spending the machines will need counts as capital spending in the discounted cash flow.

Does customer concentration lower the value?

The model values the earnings you enter. Buyers pay less when one customer makes up most of the revenue, and may tie part of the price to that customer staying.

What if I pay myself less than a manager would cost?

Then your earnings overstate what a buyer who hires a manager would keep, and a buyer will deduct the difference. Set your pay at a manager's salary when you review the adjustments, so the result reflects what a buyer would pay.

Is this a certified appraisal?

No. This is an informational estimate. A bank loan, a partner buyout or an estate matter may require a certified business appraisal, which this does not replace.
