Servo presses cost 2-3x more than mechanical. Here is how to calculate payback.
## Three ROI Sources
### 1. Production Speed
Servo presses run 20-40% faster on the same job.
Example: 45 SPM mechanical vs 60 SPM servo, 16h/day, 250 days:
- Extra 3.6M strokes/year x $0.05/part = $180,000/year
### 2. Scrap Reduction
0.5-2% scrap reduction typical. At 10M parts/year, $0.50 material cost, 1% reduction = $50,000/year.
### 3. Die Life Extension
20-50% longer die life. Example: $80,000 die, 2M vs 3M strokes = $133,000/year savings at 10M SPY.
## Full Example
$200,000 premium / $363,000 annual benefit = 6.6 month payback.
## When NOT Justified
- Under 500,000 parts/year
- Simple blanking only
- Frequent die changes
- Current press under 70% utilization
