What's going on

Before you ship a Claude-backed feature, know what it'll cost. Here's the calculation, from tokens-per-request to monthly projection at scale.

What to do about it

Three patterns dominate the waste on most Claude workloads: (1) context re-sending; (2) retry loops on validation failures; (3) agent-chain re-reads. AIUsage's audit identifies which is eating your bill and projects what you'd save — no signup required for the number.

The fastest path to your real number: paste your last 30 days of Anthropic usage at aiusage.ai. Under two minutes. If your expected delta is under 40%, the audit says so and you walk.
