Screen Printing Labor Costs: Calculate Real Wages Per Order

You know your ink costs down to the penny. You track squeegee replacement and emulsion waste. But most screen print shop owners can't answer this question: How much does labor actually cost per shirt?

This gap isn't your fault—labor tracking is harder than material tracking. A production person isn't moving at constant speed, they're juggling setup, printing, flash curing, fold-and-package, and quality checks. But without a real number, you're flying blind on your biggest expense.

Here's what the data shows: Labor typically accounts for 25-40% of total production cost in a well-run shop. If you're not measuring it, you're likely underpricing jobs, losing margin on rush orders, or burning out staff on impossible deadlines.

Let's build a framework to calculate and control labor cost per order—because precision here directly protects your bottom line.

How to Calculate Labor Cost Per Shirt

Start simple. You don't need a complex system yet.

The formula:

Labor Cost Per Shirt = (Total Labor Hours × Hourly Loaded Rate) ÷ Total Shirts Produced

What's a loaded rate? It's not just wages. It includes:

• Hourly wage or salary
• Payroll taxes (8-12%)
• Benefits (health insurance, workers' comp)
• Paid time off (vacation, sick days)

Example: A production person earning $18/hour with benefits costs roughly $24-26 fully loaded when you factor in taxes and benefits.

Now, here's where most shops go wrong: They divide labor hours by units produced, but they don't segment by job type.

Better approach—track by category:

• Single-color, multi-size orders (high volume, low setup)
• Multi-color spot color jobs (medium setup, flash curing time)
• Process color / CMYK separations (longest setup, most precision)
• Small orders under 25 pieces (setup cost is massive per unit)
• Reorders (fastest—screens already exist)

A 500-piece single-color order might cost $0.35 labor per shirt. That same 12-piece custom four-color job could cost $3.50 per shirt because setup dominates the time.

If you're pricing both the same way, one is killing you.

Measure Time-to-Production: Where Labor Actually Goes

You need real data. Estimate is your enemy here.

For the next two weeks, track these touchpoints:

• Design review & approval (includes revisions)
• Screen reclaim & prep (if screen doesn't exist)
• Screen exposure (if new color)
• Setup on press (registration, ink mixing, test prints)
• Production running (time from first good shirt to last)
• Flash cure / mid-cure time (crew availability during this phase)
• Final cure / dryer time (is this attended or unattended?)
• Inspection & quality control
• Fold, package, staging for shipment

Use a simple spreadsheet or a tool like Kontraktr that timestamps production stages. You'll spot patterns immediately:

• Is your setup taking 45 minutes when it should take 20?
• Are quality checks adding 10+ minutes per job?
• Is your dryer a bottleneck (slow crew throughput)?

What you'll likely find: 35-45% of labor on jobs under 50 pieces is setup and admin, not production.

The Hidden Labor Costs Shops Miss

You're probably not charging for these:

• Design time — Color separations, artwork corrections, file prep. Should be a line item or bundled fee, not absorbed.
• Proof approval lag — Waiting for customer revisions costs crew time you're not billing. Set approval SLAs.
• Screen storage & retrieval — Finding the right screen, reclaiming the old one, storing the new one. Often 5-10 minutes per job.
• Ink mixing & testing — Especially critical on custom color matches. This is craft work, not free overhead.
• Job transitions & cleanup — Changing ink, moving screens, wiping platens. Real time, real cost.
• Downtime during reorders — Customer delays your start. You lose crew efficiency but still pay wages.

Action: Go back to last month's orders under $300. Calculate what you actually spent in labor. You'll find several jobs where you made less than $10/hour on crew wages. Those are your pricing adjustment targets.

How to Use Labor Cost Data to Raise Prices (Without Losing Orders)

Once you know your real labor cost, you can price strategically:

For single-color, high-volume jobs:

• These are your margin killers if you underprice.
• Labor cost drops as volume rises (setup amortized across more units).
• Price aggressively at 25-50 pieces; soften price at 100+ to win reorders.

For small jobs (under 25 pieces):

• Labor cost per unit is 2-3x higher.
• Implement a minimum charge or setup fee ($25-50 depending on complexity).
• This covers your real cost and discourages low-volume tire-kickers.

For multi-color spot jobs:

• Setup is expensive. Flash curing adds time. Charge a color separation or setup fee separate from per-piece cost.
• Example: $45 setup + $0.65/piece. Now your economics work on a 25-piece three-color order.

For reorders:

• This is where margin lives. Screen exists, setup is zero, production flies.
• Price 20-30% below new order price. Margin stays strong, customer feels rewarded.
• Track reorder %: Shops with reorder rates above 30% are 2x more profitable.

Build a Labor Tracking System That Actually Works

You don't need to overthink this.

Minimum viable system:

1. Timestamp each job stage — Use a print job management system that logs production start/end times.
2. Weekly labor audit — Pull data, calculate cost per order, flag outliers.
3. Monthly trend review — Is labor cost improving or drifting up? Why?
4. Adjust pricing quarterly — Based on real data, not guesses.

If you're using a point-of-sale system or manual order tracking, you're already losing hours of admin time monthly. Kontraktr's job costing features automate this—crew logs production time, system calculates labor cost per order in real-time. No guesswork, no spreadsheet maintenance.

The best shops we work with review labor metrics weekly, not monthly. They spot inefficiencies fast and adjust process before they compound.

The Profitability Math: Why Labor Precision Matters

Let's say you run $50K in monthly revenue with 8 crew members.

Scenario 1: You don't measure labor by order

• You estimate a $1.50 labor cost on single-color jobs.
• Actual cost is $2.20.
• You're losing $0.70 per shirt.
• On 1,000 monthly units, that's a hidden $700 loss. That's $8,400 annually you're leaving on the table.

Scenario 2: You measure, adjust, and optimize

• You discover setup on small orders is inefficient.
• You implement a $30 setup fee on orders under 25 pieces.
• You adjust your per-piece pricing to match real labor cost.
• Your margin on small jobs goes from -5% to +18%.
• 200 small orders per month × $6 additional margin = $1,200 monthly improvement ($14,400 annually).

This isn't aggressive pricing. This is honest pricing based on real work.

Action Items for This Week

1. Calculate your fully loaded labor rate. Add up total annual wages + taxes + benefits, divide by 2,000 work hours. That's your baseline.

2. Pick one week and track job time blocks. Setup, production, QC, packaging. Build a simple spreadsheet with job ID, hours spent, units produced.

3. Segment your last 20 orders by type (single-color, multi-color, reorder, small order). Calculate labor cost per unit for each. Which type is actually profitable?

4. Review your pricing against actual labor cost. Be honest: Are you charging enough for setup and small jobs?

5. Set a labor cost target. Most profitable shops aim for 20-28% of revenue in production labor (crew wages). If you're above 35%, your pricing, process, or staffing needs adjustment.

Labor cost precision is the fastest lever to profitability. Data-driven shops make better decisions faster. Start this week.
