Buyers evaluating enterprise AI in 2026 are no longer asking whether it works. They are asking when it pays back, and market data now gives a reasonable answer: a median time-to-value around 5.1 months, with sales-development agents closer to 3.4 months and finance or operations agents nearer 8.9.
Why the spread by function is so wide
What a payback calculation needs before it means anything
- A baseline measured before launch, not reconstructed afterwards
- A cost line that includes integration and operation, not just build
- An agreed definition of the KPI the AI is supposed to move
- A time horizon that matches the function, not the sales cycle
