How to see last month
- Download UsageAtlas and let it pick up supported Claude credentials already on this computer.
- Open History rather than Today.
- Set the range to last month.
- Filter to Claude if you do not want Codex or Cursor in the total.
You will see tokens, requests, models, and estimated cost for that month, plus which days carried the load.
This is still not the invoice
Last-month history is for planning. Extra-usage credits and plan changes live in the Anthropic account. Confirm a billing argument there.
Questions, answered
Can I see Claude usage last month in Claude Code?
Not as a month-long history. /usage shows the current window. UsageAtlas stores local history you can reopen.
Does this include Claude historical usage before I installed the app?
It can include local session information already on the machine when the adapter can read it. Gaps happen. Going forward, days are recorded as you work.
Can I export the month?
The dashboard is the view. For an official bill, use the provider account.
