AI Cost Calculator
Model pricing, tokens, agent loops, tool calls, retrieval, infrastructure, and retries — not just a per-token estimate.
The Crescent AI Cost Calculator estimates monthly AI spend by modeling every cost driver an AI application actually has — not just the model's list price per token.

How it works
Describe your workload
Enter monthly requests, average input/output tokens, and your retry rate.
Select your model and infrastructure
Choose the model family and whether you're on serverless, hybrid, or self-hosted infrastructure.
Account for agent complexity
Add agent loop iterations, tool calls, and retrieval calls — each one adds tokens and, for retrieval, a query fee.
Read current and 10x cost
See estimated monthly cost today and at 10x usage, so scaling surprises show up before they happen.
Review the optimization estimate
The calculator flags specific inefficiencies in your inputs and estimates the savings from fixing each one.
When should I use this?
- AI usage or spend is increasing and you want to know why before the next bill.
- An agent workflow is making many model calls and you're not sure which part is driving cost.
- You're comparing models or infrastructure options before committing.
- You're preparing for a usage increase and want to see cost at 10x before it happens.
Who is this for?
- Engineering leads and CTOs sizing an AI feature before it ships.
- AI and ML engineers deciding between models or infrastructure.
- Founders and operators trying to understand where AI spend is actually going.
