Sign Shop Overhead Rates: How to Calculate Your True Costs
Table of Contents
Why Your Charge-Out Rate Is Probably Wrong
Due to your overhead rates, on the first of every month your sign shop starts roughly $87,000 in debt. That's the cost of keeping the doors open before you make a single sign - rent, payroll, insurance, equipment, vehicles, utilities. Every job you quote needs to chip away at that number. If your pricing doesn't recover overhead accurately, you're not just making less profit - you're actively losing money while feeling busy.
Most shop owners know this intuitively. But when it comes to calculating a machine charge-out rate, they do something like: take the machine purchase price, divide by expected years of life, divide by hours in a year, and call it a rate. Maybe add a bit for maintenance.
The problem is that number bears almost no relationship to what it actually costs to run that machine per productive hour. It ignores:
- Overhead - the rent, insurance, utilities, payroll, and vehicle costs that don't stop when the machine stops
- Utilisation - your machine isn't running 8 hours a day. Between setup, changeovers, maintenance, file prep, and simply not having jobs queued, the real productive time is 48-73% of available time
- Cost centre differences - production and installation have very different economics, and blending them into one rate undercharges installation and overcharges production
- Machine-specific costs - your CNC router, wide format printer, and laser cutter all have different overhead profiles. A single "shop rate" averages them into a number that's wrong for every machine
The result is a charge-out rate that feels right but doesn't cover your actual costs. You stay busy, jobs flow through the shop, and at the end of the quarter you wonder where the profit went.
This post shows you how to calculate it properly - using the same framework (OEE) that mining companies and heavy industry use to price equipment time. We know, because that's where we came from. SSQ was built by chartered engineers who spent careers doing exactly this on mines and energy infrastructure projects around the globe. The maths is the same whether you're pricing a conveyor system or a CNC router.
What Actually Goes Into Overhead?
Before you can calculate a charge-out rate, you need to know your total overhead. Most shops undercount this significantly.
Here's a realistic monthly overhead breakdown for a mid-sized sign shop (6-7 staff, CNC router, wide format printer, laser cutter):
1. General Operating Costs - ~$12,000/month
| Expense | Typical Monthly Cost |
|---|---|
| Rent / mortgage | $8,000-12,000 |
| Utilities (power, water, gas) | $800-1,200 |
| Software subscriptions (design, RIP, accounting) | $800-1,200 |
| Council rates, waste removal | $200-400 |
| Phone, internet | $200-300 |
| Cleaning, consumables | $100-200 |
Rent is the big one. If your shop is in an industrial area near metro, $10,000/month for a space big enough for production equipment is typical. This cost exists whether your machines are running or not.
2. Equipment Costs - ~$3,000/month
| Expense | Typical Monthly Cost |
|---|---|
| Computer hardware (amortised) | $500-1,000 |
| Software licenses (CAD, CAM, nesting) | $500-1,000 |
| CNC router maintenance/consumables | $300-600 |
| Printer maintenance/consumables | $300-600 |
| Small tools and workshop consumables | $200-400 |
These are the costs of keeping your production equipment operational - separate from the direct cost of materials and tooling on individual jobs, which should be quoted per job. See our CNC routing guide for how to cost tooling per linear metre of cutting.
3. Vehicle Costs - ~$2,000/month
| Expense | Typical Monthly Cost |
|---|---|
| Fuel | $800-1,200 |
| Vehicle servicing | $300-500 |
| Tolls and parking | $300-500 |
| Registration | $100-200 |
Vehicle costs are almost entirely an installation expense. If your production team doesn't leave the shop, allocate 100% of vehicle costs to installation.
4. Payroll - ~$68,000/month (the big one)
| Expense | Typical Monthly Cost |
|---|---|
| Direct wages and overtime | $45,000-55,000 |
| Superannuation (11.5%) | $4,500-5,500 |
| Leave entitlements (annual, sick, personal) | $4,000-5,500 |
| Training and professional development | $2,000-5,000 |
| Payroll tax (varies by state) | $2,000-3,000 |
| Recruitment costs (amortised) | $500-1,000 |
| Team events and perks | $500-1,000 |
Payroll is 70-80% of total overhead in most sign shops. Labour costs dominate because sign manufacturing is labour-intensive. If you're only counting base wages in your overhead, you're missing super, leave, training, payroll tax, and recruitment - easily 25-35% on top of the base wage.
5. Insurance - ~$2,000/month
| Expense | Typical Monthly Cost |
|---|---|
| Public liability | $300-600 |
| Workers compensation | $500-1,000 |
| Product liability | $200-400 |
| Professional indemnity | $100-300 |
| Property and equipment | $200-400 |
| Vehicle insurance | $100-200 |
Often forgotten entirely. Insurance is a fixed cost that must be recovered through your charge-out rate.
Total: ~$87,000/month
That number surprises most shop owners. The instinct is to think "my overheads are maybe $20-30K" because they're mentally counting rent, utilities, and wages but forgetting everything else.
If your total monthly overhead number doesn't surprise you a little, you probably haven't counted everything. Go through each category line by line. The costs you've forgotten are the ones silently eroding your margins.
Production vs Installation: Two Different Businesses
Here's the insight that changes how most shops think about pricing: production and installation are separate cost centres with very different economics.
Production is workshop-based: artwork design, printing, CNC cutting, laser engraving, fabrication, finishing. Your production team works in the shop, and their billable hours are relatively predictable.
Installation is site-based: delivery, site surveys, permitting, fitout, project management. Your installation team travels between sites, and travel time, weather, site access issues, and client delays all eat into billable hours.
The Billable Hours Gap
| Production | Installation | |
|---|---|---|
| Staff (FTE) | 5 | 2 |
| Billable hours per day | 6 | 4-5 |
| Days per week | 5 | 5 |
| Working weeks per year | 48 | 48 |
| Billable hours per year | 7,200 | 2,400 |
| Billable hours per month | 600 | 200 |
A production worker bills 6 hours of an 8-hour day. The remaining 2 hours go to breaks, cleanup, admin, moving materials, and other non-billable work. An installer, after driving between sites, setting up, and packing down, bills 4-5 hours.
The Rate Multiplier
If overhead is split roughly evenly between production and installation (both use the premises, both have payroll), but installation has a third of the billable hours:
| Monthly Overhead | Monthly Hours | Minimum Rate | |
|---|---|---|---|
| Production | ~$43,000 | 600 | $72/hr |
| Installation | ~$44,000 | 200 | $220/hr |
| Blended (average) | ~$87,000 | 800 | $109/hr |
Installation rate is 3x production rate. Not because installation work is three times harder - because installation has three times fewer billable hours to spread costs across.
If you use a single blended rate ($109/hr) for everything, you're overcharging production work by 50% (losing jobs to competitors) and undercharging installation by 50% (doing site work at a loss).
This is the same principle as demurrage in shipping. A bulk carrier sitting idle in port racks up tens of thousands of dollars per day in demurrage fees - crew wages, insurance, finance costs don't stop just because the ship isn't loading. But the ship is only half the equation. If the ship loader is the bottleneck - too slow, too much downtime, not enough throughput - then every other asset in the chain suffers. The mine keeps producing, stockpiles overflow, trucks queue up, and the people across the whole operation feel the pinch. One underperforming asset cascades into overtime, burnout, and lost revenue across the entire system. Your sign shop works the same way: if your CNC router is the bottleneck, your printer sits idle waiting for cut panels, your finishing team has nothing to finish, and then everything arrives at once and everyone's working late.
That's me at Anderson Point, Berth 2 and 3, Port Hedland, Western Australia - the world's largest bulk export port by tonnage. The conveyor below me pushes ~13,000 tonnes of iron ore per hour - about $2 million/hour in saleable product. A ship sitting idle here racks up tens of thousands of dollars per day in demurrage. The same principle applies to your sign shop - every idle machine and every bottleneck has a real dollar cost, just with fewer zeros.

What Is OEE and Why Should Your Sign Shop Care?
OEE (Overall Equipment Effectiveness) is a standard manufacturing metric used across mining, automotive, energy, and heavy industry to measure how effectively equipment time is being used. The formula is simple:
OEE = Availability x Performance x Quality
- Availability - is the machine running? (accounts for breakdowns, changeovers, maintenance)
- Performance - is it running at rated speed? (accounts for slow cycles, jams, operator delays)
- Quality - is it producing good output? (accounts for rejects, reprints, scrap)
OEE Benchmarks
OEE benchmarks from Lean Production - the industry standard reference for OEE measurement.
- 85%+ is considered world class for discrete manufacturing - a long-term aspirational target
- 60% is typical for most manufacturers. That means 40% of your machine time produces zero revenue
- 40% is common for shops that haven't measured or started optimising - not unusual, but a massive improvement opportunity
Most sign shops have never calculated their OEE. If they had to guess, they'd say 80-90%. The reality is closer to 40-60%.
Why This Matters for Pricing
If your CNC router is available 2,000 hours per year but its OEE is 60%, you have 1,200 productive hours - not 2,000. Your overhead needs to be recovered across 1,200 hours, not 2,000. That's a 67% increase in your real cost per productive hour compared to the naive calculation.
This is where most sign shops go wrong. They calculate a machine rate based on total available hours, then wonder why they're not making money despite being "busy." Being busy isn't the same as being productive.
Machine-Specific Overhead Rates
Your CNC router, wide format printer, and laser cutter don't all cost the same per hour to run. Each has different overhead allocation, different utilisation rates, and different productive hours.
Here's a realistic breakdown using our earlier $43,000/month production overhead:
Step 1: Allocate Overhead by Equipment
| Equipment | Share of Production | Monthly Overhead | Additional Costs | Total |
|---|---|---|---|---|
| CNC Router | 43% | $18,500 | - | $18,500 |
| Wide Format Printer | 26% | $11,200 | $1,000 (ink, media maintenance) | $12,200 |
| Laser Cutter | 10% | $4,300 | - | $4,300 |
| Other (unallocated) | 21% | $9,000 | - | $9,000 |
The allocation percentages reflect how much of your production effort and staff time each machine consumes. Your CNC router is likely your most-used piece of equipment in a typical sign shop.
Step 2: Calculate Productive Hours
| CNC Router | Printer | Laser | |
|---|---|---|---|
| Operational hours/day | 5 | 4 | 6 |
| Days/week | 5 | 5 | 5 |
| Weeks/year | 48 | 48 | 48 |
| Operational hours/year | 1,200 | 960 | 1,440 |
| Available hours/year | 2,000 | 2,000 | 2,000 |
| Utilisation | 60% | 48% | 72% |
The laser is the most utilised machine. The printer is the least - it spends more time on setup, file prep, drying, and changeovers between jobs. These aren't assumptions - measure your actual operational hours over a month to get your real numbers.
Step 3: Calculate Overhead Cost Per Hour
| Monthly Overhead | Monthly Productive Hours | Overhead Cost/hr | |
|---|---|---|---|
| CNC Router | $18,500 | 100 | $185/hr |
| Wide Format Printer | $12,200 | 80 | $153/hr |
| Laser Cutter | $4,300 | 120 | $36/hr |
The laser is 4-5x cheaper per hour than the printer or router. Not because it's a cheaper machine - because it has lower overhead allocation AND higher utilisation. More productive hours to spread costs across, and less overhead to spread.
Step 4: Add Profit Margin (Tiered by Utilisation)
Here's where it gets interesting. A flat profit margin per machine ignores a fundamental reality: when a machine runs continuously on a single job, your overhead recovery per hour actually improves. Less setup, less changeover, less dead time between jobs. You should pass some of that efficiency gain on to customers as volume pricing - and keep some as improved margin.
CNC Router - base overhead $185/hr:
| Job Duration | Profit Margin | Charge-Out Rate | Why |
|---|---|---|---|
| Short run (< 1 hr) | 15% | $213/hr | High setup-to-run ratio, premium for small jobs |
| Standard (1-4 hrs) | 12% | $207/hr | Standard production work |
| Long run (4-8 hrs) | 10% | $204/hr | Better utilisation, less changeover |
| Continuous (8+ hrs / multi-day) | 8% | $200/hr | Maximum utilisation, bulk discount justified |
Wide Format Printer - base overhead $153/hr:
| Job Duration | Profit Margin | Charge-Out Rate |
|---|---|---|
| Short run (< 1 hr) | 10% | $168/hr |
| Standard (1-4 hrs) | 6% | $163/hr |
| Long run (4+ hrs) | 4% | $159/hr |
Laser Cutter - base overhead $36/hr:
| Job Duration | Profit Margin | Charge-Out Rate |
|---|---|---|
| Short run (< 1 hr) | 25% | $45/hr |
| Standard (1-4 hrs) | 19% | $43/hr |
| Long run (4+ hrs) | 15% | $41/hr |
This is exactly how SSQ's pricing engine works. Machine time costs scale with utilisation - as job duration increases, the per-hour rate steps down automatically. Your customers see genuine volume discounts that are calculated from real cost savings, not arbitrary percentage discounts pulled from thin air. A customer ordering 500 signs gets a better per-unit price than someone ordering 5 - not because you decided "10% off for bulk" but because the machine runs more efficiently on longer continuous jobs. First principles, not guesswork.
Your CNC router at $207/hr is your most expensive machine to run. Every time you underquote CNC cutting time - by using a "complexity multiplier" instead of calculating from actual cut path perimeter and feed rate - you're losing money on your most expensive resource. See our CNC routing guide for how to calculate machine time from first principles.
A Worked Example: Quoting With Real Overhead Rates
Let's price a job using proper overhead rates: 20x corflute real estate signs, 600x450mm, single-sided print, square cut.
| Component | Calculation | Cost |
|---|---|---|
| Print time | 0.5 hrs @ $163/hr (printer rate) | $81.50 |
| CNC cutting time | 0.25 hrs @ $207/hr (router rate) | $51.75 |
| Production labour | 0.5 hrs @ $72/hr (production rate) | $36.00 |
| Materials (corflute + print media) | 20 signs | $45.00 |
| Production subtotal | $214.25 | |
| Delivery | 1 hr @ $220/hr (installation rate) | $220.00 |
| Total job cost | $434.25 | |
| Per sign | $21.71 |
Now compare that to what a shop using a single blended rate would quote:
The blended-rate quote is $144 cheaper on the same job. That's not a discount - it's $144 of unrecovered overhead. The shop doing it this way loses money on installation (quoted at $109 vs real cost of $220) and slightly overcharges on production (making them less competitive on production-only jobs).
Over a year, across hundreds of jobs, that pricing error is tens of thousands of dollars in unrecovered overhead.
How SSQ Handles Overhead
SSQ has a dedicated overhead configuration system that walks you through this entire calculation. You enter your monthly costs by category, your staff numbers and billable hours, your equipment allocation, and your target profit margins. SSQ calculates your charge-out rates for production, installation, and each individual machine.
Those rates then flow automatically into every quote. When a customer configures a sign on your website, the CNC cutting time is priced at your CNC router rate, the print time at your printer rate, and the labour at your production rate. No manual calculation. No averaging. No guesswork. The overhead is recovered correctly on every job because the rates are built from your real costs.
When your rent goes up, or you hire another staff member, or your utilisation changes - you update the overhead configuration and every product across your entire range recalculates. One change, all products updated.
We follow the Toyota principle: automation should free your team from repetitive work, not replace them. Your fabricators and installers are too valuable to waste on manual overhead calculations and spreadsheet quoting. SSQ handles the labour cost allocation and machine rate maths so your team can focus on production, customer relationships, and growing the business.
This is the same approach we used to price equipment time on heavy infrastructure projects. The principle doesn't change whether the machine costs $80,000 or $80 million - you allocate overhead, measure productive hours, and calculate a rate per hour. No fudge factors. No complexity multipliers. First principles engineering.

Frequently Asked Questions
How do you calculate overhead rates for a sign shop?
Add up all monthly fixed costs (rent, utilities, insurance, payroll, equipment, vehicles) and divide by your total productive billable hours per month. This gives you a minimum charge-out rate per hour. Split this by cost centre (production vs installation) for more accurate pricing, as installation typically has far fewer billable hours and therefore a much higher per-hour rate.
What is OEE and why does it matter for sign manufacturing?
OEE (Overall Equipment Effectiveness) measures the percentage of planned production time that is truly productive. It combines availability (is the machine running?), performance (is it running at rated speed?), and quality (is it producing good output?). A typical sign shop operates at 40-60% OEE, meaning 40-60% of your machine time produces zero revenue. Your charge-out rate must account for this.
What is a good machine utilisation rate for a sign shop?
Machine utilisation in sign shops typically ranges from 48% (wide format printers) to 73% (laser cutters). World-class OEE for discrete manufacturing is 85%, but most sign shops operate well below this. The key is to know your actual utilisation so your charge-out rate reflects reality, not an optimistic assumption.
Why is my installation rate so much higher than my production rate?
Installation teams have far fewer billable hours than production teams. A production worker might bill 6 hours of an 8-hour day. An installer, after travel time between sites, setup, and pack-down, might bill 4-5 hours. With similar overhead costs spread across fewer hours, the per-hour rate for installation work is typically 2-3x higher than production work.
How do I calculate a machine charge-out rate?
Allocate your production overhead to each machine by usage share, add any machine-specific costs (consumables, maintenance), then divide by the machine's actual productive hours per year (not total available hours). Factor in OEE - if the machine is only productive 60% of available time, your denominator should reflect that. Add your target profit margin to get the charge-out rate.
What overhead costs do sign shops typically forget?
The most commonly missed overhead costs are: superannuation and leave entitlements (on top of base wages), training and recruitment costs, insurance (public liability, workers comp, product liability), vehicle costs for installation teams, and software subscriptions. Payroll-related costs alone typically make up 70-80% of total overhead.
