ROI = (Value Created by AI - Total AI Cost) / Total AI Cost × 100%

Types of Value Measurement

Quantitative Measurement (Directly Measurable)

Value Type	Measurement Metric	Example
Time Savings	Reduction rate in task processing time	Report writing: 4 hours to 30 minutes
Cost Savings	Reduction in labor and outsourcing costs	Monthly cost: 2M KRW to 500K KRW
Error Reduction	Error rate, rework frequency	Typo rate: 5% to 0.5%
Throughput Increase	Cases handled per person	1 person: 50 to 200 cases/day

Qualitative Measurement (Indirect Effects)

Value Type	Measurement Method
Employee Satisfaction	Quarterly survey
Decision Quality	Tracking outcomes 6 months after decisions
Innovation Speed	Time from new idea to execution
Customer Satisfaction	Change in NPS, CSAT

AI Project ROI Calculation Example

Case: Customer Support AI Chatbot

[Costs]
  LLM API cost:            2M KRW / month
  Development & operations labor: 3M KRW / month
  Infrastructure cost:     500K KRW / month
  Total cost:              5.5M KRW / month

[Value]
  Reduction in agent case volume: 2,000 cases / month
  Agent labor cost savings:  16M KRW / month (2,000 cases × 8,000 KRW/case)
  24-hour service:          Customer satisfaction NPS +15 points
  Total value:               16M KRW+ / month

[ROI]
  Monthly net profit: 16M - 5.5M = 10.5M KRW
  ROI:     10.5M / 5.5M = 191%
  Payback period: approximately 1 month
