ZenLLM

Calculate your AI cost before the invoice does.

Use your own request volume, token counts, and provider rates to calculate monthly spend, cost per request, routing savings, and prompt-caching savings.

Calculate monthly LLM API cost

Multiply monthly requests by average input and output tokens, then apply the price per million tokens for the model you use.

Monthly LLM API spend.

Cost per request.

Input-token share of the bill.

Estimate routing and caching savings

Model how much spend can move to a lower-cost model and how much repeated input context can be cached or removed.

Potential monthly and annual savings.

Optimized monthly spend.

A direct path from estimate to measured workflow-level recommendations.
