The true cost of AI agents in 2026: subscriptions, credits and wrong answers.
On the pricing page, AI agents look almost free. In practice, the subscription is the smallest line in the budget. Here is how to count the real cost before you commit.
- Sticker price is $0 to $250 a month for most agent plans.
- Credits can multiply that on long tasks.
- People’s time to set up and supervise is usually the largest cost.
- Wrong answers are the cost nobody budgets for.

| Setup | 20 hours of your time | Done by the builder |
| Supervision | 5 hours a week checking | Approvals built into the workflow |
| Accuracy | Unknown | Measured weekly on your cases |
| If it fails | Your problem | Builder keeps working (at IAW, in writing) |

- You need a number to report to a partner, board or regulator
Frequently asked questions
Why do credit-based agents cost more than expected?
Long, multi-step tasks use many more credits than short ones, and failed runs still use credits.
What is the biggest hidden cost?
People’s time: setting the agent up, checking its work and fixing its mistakes.
How does IAW price?
Fixed price per build, from $1,500 for a single results-oriented AI, scoped in writing before you pay. You own what we build.
How do I estimate an AI agent’s ROI?
Measure hours and errors today, multiply by cost, and compare with the agent’s total monthly cost, including supervision.
Are credit-based plans bad?
No. They are fair for occasional work. They become expensive and unpredictable for long, repeated tasks.
