I ran $11,442 of Claude usage on a $200/month plan.

60 active days of my own sessions, 24 May to 27 August 2026, priced at Anthropic list prices. I did not know the figure until I built the tool that reads it.

Plan fee, this window

Ratio

17.9×

11,442 ÷ 640.00 = 17.9

The fee is prorated to the window rather than charged as a whole month — against one month's $200 the same usage would read 49× instead of 17.9×.

Read the source

Not money saved — what the same work would have cost through the API. The money that left my account was $640.00. What that means, and how it was read.

The screen behind it

This is the dashboard, not a mockup.

Everything above comes from caprock report, which reads the same database this screen draws.

The Cost screen as it ships. Captured on a real machine — the figures on it are a different window than the all-time totals above, so they will not match line for line.

Your turn

Your history is already on your disk. This just reads it.

Caprock reads the transcripts you already have, so the number is there on first run — every session you have run, not just the ones from now on. Free, Apache-2.0, one binary, nothing leaves your machine.

Release binaries for macOS, Linux and Windows, and the full walkthrough, are on the install guide.
