GenAI Roll-out

Case Interview Practice > 
Math

To size the opportunity, we’d like to estimate the potential productivity impact of the GenAI copilot. The pilot was rolled out to 100 underwriters across 5 regional offices. The client believes that, if scaled, GenAI could cut underwriting time by 20–30% on average.

Assume the following:

  • There are 5,000 total underwriters across the country.
  • On average, underwriters process 1.5 applications per day.
  • The average labor cost per underwriter is $120,000/year.
  • There are 250 working days per year.

What is the potential annual cost savings from scaling the GenAI tool nationally?

Sample answer from an expert consultant

Step 1: Calculate labor cost savings per underwriter

  • Labor cost = $120,000/year
  • 20–30% productivity increase implies the same output in 70–80% of time → savings = 20–30% of cost
  • That’s $24,000–$36,000 per underwriter

Step 2: Multiply by total underwriters

  • Total = 5,000 underwriters
  • Total savings = 5,000 × $24,000 → $120M (low end)
  • Total savings = 5,000 × $36,000 → $180M (high end)

Conclusion:
If productivity gains scale linearly, the client could save $120M–$180M annually in labor costs by rolling out GenAI to all 5,000 underwriters.
