How CNC Shops Businesses Are Valued
CNC shops are valued on Seller's Discretionary Earnings (SDE) or EBITDA. The valuation is driven by machine capabilities, programming expertise, and customer contracts. Multi-axis CNC shops with lights-out capability and production contracts for aerospace, medical, or defense customers command the highest multiples. The key risk buyers evaluate: how much of the programming and setup knowledge is locked in the owner's head?
SDE = Net Profit + Owner’s Salary + Owner Benefits + Discretionary Expenses
They then multiply your SDE by an industry-specific multiple derived from comparable transactions. For CNC Shops businesses, that multiple currently ranges from 2.5x to 4.5x.
Quick Example
A CNC Shops business with $320K in SDE at a 3.5x multiple would have an estimated value of $1.12M. At the full range of 2.5x–4.5x, the estimated value is $800K–$1.44M.
Current CNC Shops Multiples
These ranges reflect recent transaction data for CNC shops. Shops with multi-axis capability, quality certifications, and production contracts consistently trade at the upper end.
| Revenue Range | Typical SDE Multiple | What This Means |
|---|---|---|
| Under $1M | 2.0x – 2.8x | 3-axis, owner-programmer, job shop |
| $1M – $3M | 2.5x – 3.5x | Multi-axis, trained programmers, production runs |
| $3M – $10M | 3.0x – 4.5x | AS9100/ISO, OEM contracts, lights-out capability |
| $10M+ | 4x–7x EBITDA | Aerospace/defense precision manufacturers |

What Drives Your Number Up (or Down)
Two CNC Shops businesses with the same revenue can be worth very different amounts. Here are the factors that separate high-multiple from low-multiple businesses:
Drives Multiple Up
- Multi-axis capability — 5-axis machining centers expand the addressable customer base
- Lights-out manufacturing — automated production that runs unattended increases capacity
- AS9100 or ISO 13485 — aerospace or medical quality certifications open premium markets
- Documented programs and processes — CNC programs and setup sheets that transfer with the business
- Production contracts — recurring orders from OEMs with volume commitments
Drives Multiple Down
- Owner is the only programmer — all CNC programming expertise leaves with the seller
- 3-axis only — limited capability restricts the customer base to simpler parts
- Job shop with no contracts — one-off work with no forward revenue visibility
- Aging machines — CNC equipment needing retrofits or replacement
- No quality certifications — excluded from aerospace, medical, and defense work

Frequently Asked Questions
What is the average CNC shop worth?
CNC shops typically sell for 2.5x to 4.5x their Seller's Discretionary Earnings (SDE). For a shop with $320K in SDE, that translates to an estimated value of $800K to $1.44M. Shops with multi-axis capability, quality certifications, and production contracts trade at the higher end.
What SDE multiples do CNC shops trade at?
Based on recent transaction data, CNC shops trade at SDE multiples of 2.5x to 4.5x. Larger shops valued on EBITDA trade at 4x to 7x. Machine capability, certifications, and the transferability of programming knowledge are the primary factors.
How can I increase the value of my CNC shop before selling?
Document all CNC programs and setup procedures so they transfer with the business, invest in multi-axis capability, obtain AS9100 or ISO certifications, secure production contracts with OEMs, and train programmers so your expertise isn't the only programming resource in the shop.
