Investing in an automatic packaging line is a decision worth hundreds of thousands of euros. ROI is not just a formality: it is the tool that transforms an expense into a strategic decision based on real data.
Components of ROI in packaging
Return on investment for an automatic line is calculated by summing all annual economic benefits and dividing by the investment cost. The four main benefits are: labour savings, waste reduction, production capacity increase and reduced machine downtime.
- Labour savings: 1 operator = ~€35,000/year (salary + social charges)
- Waste reduction: -15% vs manual production = thousands of € annually
- Capacity increase: +30-50% vs semi-manual line
- Downtime reduction: preventive maintenance vs reactive repairs
- Pack cost reduction: thermoformer vs pre-formed trays
Formula and practical calculation example
ROI (%) = (Annual benefits – Annual operating costs) / Total investment × 100. Example: automatic line at €120,000, replaces 3 operators (€105,000/year), reduces waste by 20% (€20,000/year), additional operating costs €15,000/year. ROI = (125,000 – 15,000) / 120,000 = 91.7% → break-even in 13 months.
- Total annual benefits: labour savings + waste reduction + production increase
- Annual operating costs: energy + maintenance + spares + depreciation
- Break-even = Investment / (Benefits – Operating costs)
- Add machine residual value at 10 years to the calculation
Factors that improve ROI
ROI improves with more production shifts: a line running 3 shifts (24h) has 3x the ROI of one running 1 shift. Contracted preventive maintenance reduces unplanned stoppages (which cost on average €500-2,000/hour of lost production). Tax incentives such as the 4.0 investment tax credit for new capital goods can reduce effective cost by 20-40%.
- 3-shift production: ROI 3x vs 1 shift
- Preventive maintenance: -60% unplanned stoppages
- Industry 4.0 tax credit: 20-40% reduction in effective cost
- EMA Care service contract: guaranteed machine availability
