AI Agent Cost Calculator

Estimate what an AI agent costs to run: per task, per day and per month. Set your volume, tokens, tool calls, retries and prompt caching, pick a model, then see what the same workload would cost on other models. Prices are copied from each vendor’s own pricing page.

An estimate, not a quote. Loading prices… It uses standard API rates only: no batch or priority modes, regional uplifts, tool fees (such as web search) or cache-write surcharges. Different vendors count tokens differently, so token counts are not directly comparable across models. Want to count tokens from real text first? Use the AI Token Calculator.

What if you switch model?

Same workload, same token counts, each model’s own price (including its own cache-hit price). Sorted cheapest first. flag marks promotional, preview or tiered prices; read the note on the model before relying on it.

How it is calculated

Agent loop: with N tool calls the model is called N+1 times. Every call re-reads the whole context, so input grows by “tokens per tool call” each turn: input = (N+1) × base + tokens × N(N+1)/2. Untick the checkbox to bill tool tokens once instead.
Output: your average output per task, priced at the model’s output rate.
Caching: the % you enter is billed at the model’s cache-hit price instead of the normal input price. Cache writes cost extra on some vendors (Anthropic charges 1.25x for a 5-minute write) and cache storage is charged separately by Google; neither is included, so high cache shares are optimistic.
Retries: adds that % of the whole task cost again.
Month = per-day cost × days per month.
Long prompts: several models charge more above a context size (for example 200k tokens). The calculator warns when one call may pass that line but still uses the standard rate.
