"Show me the payback."
That's the first thing any factory owner says when you pitch a corrugated box machine. And they're right to ask. A production line isn't a laptop—you can't return it if the numbers don't add up.
Here's the math for three real-world production scales, built from Yoco-Group's equipment data and actual customer P&L.
| Cost Item | Amount | Notes |
|---|---|---|
| Equipment depreciation (8yr straight-line) | $570 | $55K ÷ 96 months |
| Labor (3 operators × $1,200/mo) | $3,600 | Semi-skilled operators |
| Electricity (~25kW, 8h/day, 26 days) | $520 | $0.10/kWh |
| Maintenance + consumables (blades, ink, belts) | $450 | ~$5,400/year |
| Raw material (corrugated sheets, 5K×26 days) | $19,500 | ~$0.15/sheet avg |
| Total monthly operating cost | $24,640 |
| Revenue Item | Amount | Notes |
|---|---|---|
| Box sales (130K units × $0.28 avg) | $36,400 | Mixed sizes, regional pricing |
| Scrap/waste recovery | $400 | Trim and reject sales |
| Total monthly revenue | $36,800 |
Key takeaway: At entry scale, labor is your biggest variable cost. Semi-auto keeps headcount low while output stays predictable.
| Cost Item | Amount | Notes |
|---|---|---|
| Equipment depreciation (8yr) | $2,240 | $215K ÷ 96 months |
| Labor (5 operators × $1,500/mo) | $7,500 | Skilled operators, 2 shifts |
| Electricity (~65kW, 16h/day, 26 days) | $2,704 | Higher power draw, longer runtime |
| Maintenance + consumables | $1,200 | More complex machinery |
| Raw material (390K sheets/mo) | $58,500 | Volume discount: ~$0.15→$0.13/sheet |
| Total monthly cost | $72,144 |
| Revenue Item | Amount | Notes |
|---|---|---|
| Box sales (390K × $0.26 avg) | $101,400 | Volume brings mix toward standard sizes |
| Die-cut specialty boxes (premium +15%) | $12,000 | ~20% of output at higher margin |
| Total monthly revenue | $113,400 |
Key takeaway: The real ROI of automation at scale isn't the boxes you make faster—it's the boxes you couldn't make at all without the die cutter.
| Metric | Value |
|---|---|
| Monthly output | 1.04M boxes |
| Monthly operating cost | ~$165,000 |
| Monthly revenue | ~$275,000 |
| Monthly net | ~$110,000 |
| Raw payback | ~6.8 months |
At 40,000+ boxes/day, the math flips. The biggest risk isn't price competition—it's machine downtime.
| Utilization Rate | Monthly Revenue | Monthly Net | Effective Payback |
|---|---|---|---|
| 90% (target) | $275,000 | $110,000 | 6.8 months |
| 75% | $229,000 | $64,000 | 11.7 months |
| 60% | $183,000 | $18,000 | 41.7 months |
Key takeaway: The biggest line isn't always the best line. Buy for your confirmed orders, not your sales pitch.
Before you sign the PO, answer these three questions:
1. What's your worst month in the last 12 months? Size your line for 80% of that worst month. You can always run overtime in good months. You can't un-depreciate an oversized machine in bad months.
2. What percentage of your orders are repeat vs. one-off? Repeat orders = predictable capacity planning. One-off orders = you need flexibility, not raw speed.
3. Can your sales team sell the output of this machine? This sounds obvious. It's the question most buyers skip.
A: Raw material cost. If you can negotiate even a $0.01/sheet discount through volume, a 40K/day line saves $10,400/month—nearly 10% of monthly profit.
Q: New machine vs. refurbished—what's the real savings?A: Refurbished typically saves 30-40% on purchase price but costs 50-100% more in maintenance over the first 3 years. For lines above 15K/day, new machines with warranty and installation support almost always win on TCO.
Q: What about Southeast Asian market specifics?A: Vietnam and Indonesia: 0% import duty on packaging machinery per ASEAN Trade in Goods Agreement (ATIGA) with Form D certification. Thailand: 5% duty, fast customs clearance (3-5 days) if machine meets TIS standards.
