Pricing Your Maker Work: Machine-Hour, Material, and Labor Cost Calculations for Custom Jobs

The site's existing "how to make money" content covers the business side of turning a maker tool into income — what services sell, what platforms to use, the legal and insurance groundwork. What's missing is the actual math: how to figure out what to charge for a specific job so you're not quietly losing money on every order. This is the calculation most hobbyists skip, and it's the reason so many small maker businesses either underprice themselves into an unsustainable side hustle or overprice themselves out of the market because they guessed instead of calculated.

The Four Cost Categories Every Job Actually Has

CategoryWhat It IncludesCommon Mistake MaterialFilament/resin, sheet stock, wear items consumed (nozzles, bits, laser lens life)Pricing only the material weight/area used, ignoring waste, failed attempts, and support material Machine timeAmortized cost of the machine itself, plus consumables tied to runtime (belts, bits, tube life)Treating machine time as free because you already own the equipment LaborDesign/file prep, setup, babysitting the job, post-processing, packagingOnly counting active hands-on time, not file prep or the babysitting time a print or cut job actually demands OverheadElectricity, shop space, software licenses, marketing, platform feesIgnoring it entirely because no single job feels like it costs much overhead

Machine-Hour Cost: The Number Most People Never Calculate

Every machine has a real cost per hour of runtime, even if you already own it outright. The calculation:

Machine-hour cost = (Purchase price ÷ Expected lifetime hours) + (Annual maintenance cost ÷ Annual runtime hours) + Electricity cost per hour

For a $1,200 CNC router expected to run 3,000 hours before major component replacement, with $150/year in belts, bits, and bearings, running 400 hours/year, and drawing 1.5kW at $0.15/kWh:

Depreciation: $1,200 ÷ 3,000 = $0.40/hour
Maintenance: $150 ÷ 400 = $0.375/hour
Electricity: 1.5kW × $0.15 = $0.225/hour
Total machine-hour cost: roughly $1.00/hour

Run the same calculation for a laser or 3D printer using your own purchase price, realistic tube/hotend/rail lifetime, and local electricity rate — the exact number matters less than having one instead of treating machine time as free. See our preventive maintenance guide and CO2 tube care guide for realistic component lifetime figures to plug into this formula for your specific machine.

Material Cost: Count the Waste

Filament and sheet stock cost calculations routinely undercount because they price only the part that ends up in the finished piece:

3D printing: include support material weight, purge tower volume on multi-color jobs, and a realistic failure rate (5-10% for anything unattended is common) amortized across successful jobs.
Laser cutting: price the full sheet if a job's nesting doesn't fill it efficiently, not just the cut area — see our nesting software guide for reducing this waste, but budget for what's left over even with good nesting.
CNC: include tool wear cost per job (bits have a finite life, especially in aluminum or abrasive composites) and scrap rate from tabs, test cuts, and setup errors.

Labor: What Actually Counts

The time that's easy to undercount is everything that isn't the machine actively running: converting a customer's file to something printable or cuttable, slicing/CAM setup, bed leveling or work-zero setup, watching the first layers or first pass for failure, removing supports or tabs, sanding, finishing, and packaging. On a typical custom order this "invisible" labor often exceeds the machine's actual runtime. Track it honestly on a few real jobs with a timer before setting a standard labor rate — most people are off by 2-3x on their first guess.

Putting It Together: A Worked Example

A custom engraved sign: 45 minutes of laser runtime, $8 in plywood (including waste), 20 minutes of design/file prep, 10 minutes of setup and material loading, 15 minutes of finishing and packaging.

Add these together for your true cost, then apply your margin on top — margin is a business decision, not a cost, and should be a deliberate percentage you choose, not whatever's left after guessing at a round number price.

Platform and Payment Fees

If you're selling through Etsy, a marketplace, or accepting card payments, factor the actual fee percentage into your overhead calculation rather than treating it as an afterthought that eats into margin after the sale — a 6-9% combined platform-and-payment-processing cut on top of everything else is common and needs to be priced in up front, not discovered after your first month of sales.

A Simple Rule for Getting Started

If you don't yet have real numbers for your machine-hour cost, a reasonable starting formula while you gather that data is: (material cost × 2) + (total time in hours × your target hourly rate), then round to a sensible price point. It's a rough approximation, not a substitute for the full calculation above, but it's better than pricing purely on gut feel or by copying a competitor's listed price without knowing their actual costs.

The point of doing this math isn't to squeeze every job for maximum margin — it's to know, with actual numbers, whether a given price covers your real costs or is quietly subsidized by treating your own time and machine wear as free. Once you have your machine-hour and labor numbers calculated once, pricing every future job becomes a five-minute calculation instead of a guess.
