Agentic AI ROI: Board-Ready Framing

Three value categories, one payback formula, a discount table for vendor case studies.

Three value categories

Time saved
Operational hours displaced
Net hours back per agent per month
Deflection rate
Tickets / convos handled end to end
Vendor metric, validate independently
Throughput
More work without more headcount
Top-line uplift, not just cost-out
Risk reduction
Compliance and error rate
Harder to monetise; defensible only with data

Payback formula

Payback months = TCO_year1 / (monthly_value_realised - monthly_run_rate_cost)

where
  monthly_value_realised = hours_saved * loaded_hourly_rate
                         + uplift_throughput * gross_margin_per_unit
  monthly_run_rate_cost  = platform + tokens + compute + ongoing FTE

For board approval, the discount we recommend: subtract 30% from any vendor-supplied deflection or productivity figure, then run payback. If it still clears 18 months, it is defensible.

Five-step ROI build

1
Baseline
Measure today's hours, resolutions, and error rate over 60 days.
2
Pilot
Run a 90-day pilot with a fixed scope. Record agent-handled vs human-handled volumes.
3
Discount
Subtract 30% from vendor-claimed deflection. Use the discounted number for board math.
4
Model
Build a year-one and year-three model with sensitivity bands at -25% and +25%.
5
Decide
Approve if discounted payback is under 18 months and year-three NPV is positive.

What to discount in vendor case studies

  • Cherry-picked use case
    Vendor case studies pick the deployment that worked. Assume 30% lower deflection on yours.
  • Pre-AI baseline gaming
    Pre-AI hours often include process bloat the AI removes; some of the uplift would have come from process redesign alone.
  • Hidden FTE retention
    Most case studies show cost-out by deflection but the team stays the same size, doing different work. Honest framing: redeployed throughput, not headcount saved.
  • Year-one launch costs missing
    Implementation, integration, training are absorbed by the vendor's success team in the case study. They are real costs in your deployment.

One quote for the deck

The right number for a board deck is what survives a 30% discount on every vendor-supplied metric and still clears 18-month payback. Anything less is selling, not analysing.
