How to use this calculator
Enter your DAU, per-user request rate, tokens per request, and the average tool calls, vector queries and memory tokens. Pick a model tier; the result breaks cost into inference, tools, vector and storage.
Why per-DAU cost matters
Cost per daily active user is the unit economics metric investors and finance teams track. The benchmark bar shows where you sit versus a typical agent product.
Sources
Inference, vector, and storage unit costs are sourced from official provider pricing pages (OpenAI, Pinecone, Upstash) and validated at build time, versioned in the platform configuration.
Frequently asked questions
What does this calculator include?▾
LLM inference, tool-call execution, vector/RAG queries and memory storage — the four dominant cost drivers of an agentic product — rolled up monthly and yearly by DAU.
How can I reduce agent infra cost?▾
Model routing (sending easy turns to a cheaper tier) usually gives the biggest win; the calculator quantifies the saving versus your current tier.
Where do the unit costs come from?▾
Placeholder cloud + provider unit costs in a versioned JSON config. Replace them with your own bill rates; the footer shows the version and update date.
