Financials & ROI
Potential Public Health Savings:
- 1 avoided injection complication can save £50–£100 in treatment costs
- Distributing 100,000 devices could prevent 5–10% of complications:
- 5,000 complications × £50 = £250,000 saved
- 10,000 complications × £100 = £1,000,000 saved
- ROI for charities: £1 saved for every £0.25–£0.35 spent
Optional Commercial / Sustainability Margin:
- Cost per unit: £0.35
- Suggested program price: £0.50/unit
- Gross margin: ~£0.15/unit for sustainability (covers shipping/admin)
- Example for 100,000 units: £50,000 revenue – £24,000–£36,000 cost = £14,000–£26,000 margin
