ROI Calculation Logic

For a 10-hectare paddy farm, automating water level management could reduce annual labor time by ~15% (e.g., 2 workers × 200 hours/person/year × $13.50/hour = ~$5,500 (AI est.)). Additionally, a 5% yield increase from optimized water management (e.g., 10ha × 500kg/10a yield × $2.00/kg sales price × 0.05 = ~$50,000 (AI est.)) combined with a 10% reduction in water resource costs (e.g., ~$3,500 (AI est.) annual cost reduction) could result in an annual economic effect of ~$59,000 (AI est.). Considering brand value enhancement from stabilized quality, the total annual impact is estimated at ~$100K (AI est.).
