AI Agent Cost Calculator
Estimate what an AI agent will really cost you each month. Pick your use case, team size, and usage level, and see a per-agent estimate built from verified entry pricing — including which agents stay flat and which bills quietly scale with usage. Estimates are directional, not quotes.

Watch the model · At moderate usage, GitHub Copilot and Claude Code and Devin and Cursor and Replit Agent and Atoms and Kiro have a lower entry price than Codex but can cost more per month, because their bill scales with usage while Codexstays flat. Cheap headline prices aren’t always cheap.
How these estimates are calculated
Estimates start from each agent’s verified entry price, re-checked monthly against its official pricing page. They are directional, not quotes.
- Flat / per-seat subscriptions are estimated as the entry price × seats, and do not change with usage.
- Usage-based agents (credits, tokens, per-resolution, compute) show a range: the low end is the entry allotment, the high end assumes heavy use (≈5× at “heavy”, ≈2.5× at “moderate”).
- Open-source agents have no license fee — you pay only your own model API costs, which vary by model and volume.
- Custom enterprise agents have no public price and require a sales quote.

Why AI agent pricing is hard to compare
The headline price of an AI agent rarely tells you what you’ll pay. The market has splintered into pricing models that behave very differently: flat subscriptions, per-seat plans, and — increasingly — usage-based billing by credits, tokens, resolutions, or compute units (ACUs). Two agents can both advertise “$20/month” and bill you wildly different amounts once you actually use them.
That’s the trap this calculator is built to expose. Flat plans are predictable; usage-based plans are cheap to start and can climb fast under heavy use. For a light evaluation, a usage-based agent is often the cheapest option; for a full-time team workload, a flat plan can win even at a higher entry price. The estimates here start from our verified entry pricing and scale it with disclosed assumptions so you can see the crossover for your own situation.

Frequently asked questions
How much does an AI agent cost per month?
It depends on the category and pricing model. Coding agents start around $20/month, general assistants $20–$40/month, and enterprise AI sales and support agents run from hundreds to thousands per month. The calculator estimates a range for your use case from verified entry prices, and flags usage-based agents whose bills grow with volume.
Why do two agents with the same headline price cost different amounts?
Because the pricing model differs. A flat subscription stays the same no matter how much you use it, while a usage-based agent (billed by credits, tokens, resolutions, or compute) grows with volume — so a $20 usage-based agent can cost more than a $20 flat one at heavy use. The calculator makes this difference visible.
Are these cost estimates accurate?
They are directional estimates, not quotes. Each starts from the agent's verified entry price (re-checked monthly against its official pricing page) and applies transparent, disclosed assumptions for seats and usage. Always confirm current pricing on the vendor's own site before deciding.
What is the cheapest way to run an AI agent?
Open-source agents like OpenHands, GPT Researcher, and Browser Use have no license fee — you self-host and pay only your own model API costs, which can be cents to a few dollars for light use. Among hosted tools, coding agents at ~$20/month and free tiers are the lowest-cost entry points.
