Rush jobs are the lifeblood of CNC shops—and your profit margin depends on pricing them right. Customers will always need parts yesterday, but accepting every expedited order without proper premiums and capacity planning erodes your bottom line and stretches your team thin. This guide walks you through structuring rush pricing and protecting your shop's profitability.
Why Rush Pricing Matters
Standard lead times exist for a reason: they let you batch jobs, optimize tool paths, and run your machines efficiently. When a client demands a turnaround in half the time, you're breaking that rhythm. You're pulling operators off scheduled work, prioritizing setups that might waste material, and risking quality issues if your team rushes. Without premium pricing, you're essentially paying them to disrupt your operation.
The best shops treat rush jobs like a service tier, not an exception. It signals to customers that expedited work has real costs, and it protects your capacity for profitable, planned production.
Structuring Rush Fees
Standard Multipliers
Most CNC shops apply a rush surcharge between 25% and 75% of the base job cost, depending on how compressed the timeline is:
- 1–2 week lead time: 15–25% premium
- 3–5 day lead time: 30–50% premium
- 24–48 hour turnaround: 50–100% premium
- Same-day or next-day: 100%+ premium (or decline entirely)
These aren't arbitrary numbers. A 50% markup on a $2,000 job ($1,000 additional revenue) should cover the overhead of disrupting your schedule, potential material waste from expedited sourcing, and the cost of running overtime if needed.
Tiered Pricing by Complexity
Slap a flat surcharge on a simple aluminum bracket, and you might be leaving money on the table. Complex multi-axis jobs or tight tolerances get exponentially harder to rush:
- Simple 2D parts (flat stock, basic pockets): Lower rush premium (20–30%)
- 3-axis or medium complexity: Mid-tier premium (40–60%)
- 5-axis, tight tolerances, or specialized materials: Higher premium (70%+) or impose minimum lead times
A 5-axis part with 0.001" tolerances can't be rushed without real risk. Price accordingly or set a hard floor on how short you'll accept the timeline.
Capacity Planning to Protect Rush Margins
Pricing premiums only works if you actually reserve capacity for rush jobs. Otherwise, you'll accept them, blow your schedule, and erode margins trying to keep everyone happy.
Reserve Capacity
Dedicate 10–15% of your monthly machine time to rush work. If you run three mills and a lathe at 80% capacity, you're leaving room for expedited jobs without crushing your standard workflow. This buffer is your safety net and your profit center.
Track What Rush Jobs Cost You
Log the true cost of each expedited order:
- Material cost (including waste from expedited sourcing)
- Machine time at actual run rates
- Setup time (often inflated on rush jobs)
- Labor, including any overtime paid
- Overhead allocation
After six months, you'll see which rush timelines are actually profitable and which ones drain you. A $2,000 job that costs $1,800 to produce because you had to overnight specialty material and pay overtime isn't a win.
Communication and Qualification
Before you quote rush pricing, qualify the customer:
- What's the real deadline? Many clients say they need something urgently but have flexibility they haven't mentioned.
- Is the part design locked? Last-minute design changes on a 48-hour job are a recipe for rework and losses.
- Will they accept priority placement? Confirm they understand their job bumps others. Transparency prevents relationship damage.
- Can they commit to payment terms? Rush jobs should be paid upfront or on receipt, not 30 days net.
Marketing Rush Capacity as a Service
Customers don't always know you can do rush work. List your expedited turnaround options on your website and on platforms like Mercoly where buyers search for manufacturing partners. Explicitly state your rush fees and timelines; it positions you as professional and filters for serious buyers willing to pay for speed.
Frequently Asked Questions
Q: Should I ever accept a rush job below my normal capacity buffer? No—not without raising the premium significantly. If you're already at 90% capacity, a rush job at standard pricing will force you to either delay other customers (risking contracts) or work unprofitable overtime. Increase the surcharge or refer the work out.
Q: How do I handle repeat customers who always rush? Set expectations early: rush pricing applies every time, no exceptions. If a customer routinely needs expedited work, offer them a discounted annual retainer for guaranteed rush slots, but don't absorb the cost yourself.
Q: Can I set a minimum rush fee instead of a percentage? Absolutely. For very small jobs, a percentage markup might only yield $50. A $200 or $300 minimum rush fee ensures the premium covers your friction costs, regardless of job size.
