The Governance Tax Nobody Talks About
AI vendors promise the moon. Here's what their ROI calculators miss.
77% Review Rate
Nearly every AI output needs human review. That's not automation—that's augmented decision-making with oversight costs.
38% Rework Burden
More than a third of AI outputs need correction. You're paying for the AI generation PLUS human fix time.
Infrastructure Overhead
Security, compliance, specialist salaries, training. The hidden costs that kill ROI before you realize it.

Moderate but viable
Model Verdict
"MODERATE ROI — Review oversight design. Reduce rework rate to improve returns."
Key Insight
The AI works but governance costs are eating 75% of your gross savings. Focus on reducing rework rate from 38% to 20% and you double your net benefit. That's actionable intelligence you can use to optimize before scaling.
Why This Matters for 2026 AI Deployments
AI adoption in finance is accelerating but so is governance scrutiny. Regulators want audit trails. CFOs want ROI proof. Internal audit wants control frameworks. This calculator bridges the gap between AI hype and financial reality. It gives you the number that matters: net ROI after you pay for oversight.
