How do I price CNC sign work and relief carvings? A guide to quoting custom CNC projects

Overview

Pricing CNC work is one of the most common questions in the software's user community and one of the hardest skills to develop. There's no single formula. Pricing depends on your market, your overhead, your skill level, and what customers in your area will pay. This guide covers widely used approaches and formulas from experienced CNC woodworkers. Every dollar figure below is a starting-point range from community discussions, not an official or verified rate, so adjust it to your own costs and market.

The Core Formula: Cost + Markup

The most reliable starting point:

Price = (Material Cost + Machine Time Cost + Design Time Cost + Finishing Time Cost) × Markup

1. Material Cost

• Actual cost of the wood, MDF, or other material used
• Include waste (a common rule of thumb is to add 20 to 30% for waste and off-cuts)
• Include consumables: stain, paint, clear coat, hardware

2. Machine Time Cost

Estimate your hourly machine rate to cover:

• Tool wear: Bits don't last forever. Many shops budget roughly $5 to $15/hour for bit replacement on a busy machine
• Machine depreciation: Divide purchase price by expected lifetime hours (a $5,000 machine running 1,000 hours/year for 5 years = $1/hour depreciation)
• Power/electricity: Roughly $0.50 to $1.50/hour depending on spindle size and local power rates
• Overhead share: Rent, insurance, software subscriptions allocated per hour

Machine rates people quote range widely, roughly $30 to $150/hour depending on overhead. Many hobbyist shops start at $50 to $60/hour.

3. Design Time

• If you designed the file from scratch: charge for that time at your design rate (people commonly quote $25 to $75/hour)
• If you purchased clipart or used a customer-provided file: minimal design time
• For repeat jobs (same file): design time = zero, but you can still charge a setup fee

4. Markup

Multiply total cost by a markup factor:

• 1.5× for high-volume, competitive market work
• 2.0× (100% markup) is common for custom small shops
• 3.0× or more for highly unique artistic pieces, one-of-a-kind work

The Per-Square-Inch Method

A popular quick-quote approach for signs:

Price = (Square inches of sign) × Rate per square inch

Example starting-point rates by sign type (community figures, no single source, so test them against your own costs):

• V-carve text on painted MDF: $0.50 to $1.25 per sq in
• 3D relief carving on hardwood: $1.50 to $3.00 per sq in
• Painted full-color signs: $1.00 to $2.00 per sq in
• Simple profile cut signs: $0.25 to $0.75 per sq in

Example: 24"×12" (288 sq in) V-carved oak sign at $1.00/sq in = $288 base

Adjust rate up for:

• Expensive hardwoods
• Highly detailed carving
• Rush orders
• Custom painting/finishing included

Machine Time as the Primary Driver

Many experienced CNC shop owners price based almost entirely on machine time:

1. Get the estimated cut time from the software's toolpath summary (12.5 estimates account for your machine's acceleration, so they are closer to real run time)
2. Multiply by your machine rate (include all overhead)
3. Add material cost
4. Add finishing labor at your hourly rate

Example:

• Cut time: 45 minutes
• Machine rate: $60/hour → $45 machine cost
• Material: $12
• Finishing (1 hour at $20): $20
• Subtotal: $77
• With 2× markup: $154

What The Market Will Bear

Cost-plus pricing tells you the minimum. Market pricing tells you the maximum:

• Research what comparable products sell for at local craft fairs, online marketplaces, and local sign shops
• Don't undercut the market, because it devalues everyone's work including yours
• Custom CNC work commands premium prices because the buyer is getting something unique
• Price to the value delivered, not just the cost incurred

Example: A simple wooden sign that takes 20 minutes to machine might sell for $45 to $60 at a craft fair. That's a $135 to $180/hour effective rate on machine time alone, so don't leave that money on the table.

Pricing for Repeat Customers / Templates

Once you've made a design and proven it, subsequent copies cost less to produce. Options:

1. Keep same price: Higher effective margin on repeat runs, since you've already paid for design time
2. Offer volume discount: 3rd copy for 15% off, 5+ copies for 25% off
3. Create a product line: If the design is popular, list it with a fixed price and produce on demand

Common Pricing Mistakes

• Forgetting to charge for design time ("it's just a quick file"). Design time is real time
• Underestimating finishing time. Sanding, painting, and clear coating can take as long as the CNC cut itself
• Not accounting for failed cuts and material waste
• Pricing against mass-produced imported signs rather than against local custom competition
• Not raising prices as your quality and speed improve
