Claude API Usage Data Shows Impact of New Limits on Max Plan Users

User Data Shows Significant Usage Reduction After Limits

A long-term Claude user on the Max 20x plan has shared detailed API-equivalent usage data showing the impact of recently implemented limits. The user, who has been on Max plans since their release in May and previously used multiple $20 plans, experienced a noticeable change in usage patterns approximately 8 days before the post.

Before vs After Usage Comparison

Before limits (22-day period):

• Total spend: $4,618.17
• Average daily usage: ~$209.92/day
• Pattern showed binge days with March 20 at $876, and March 14, 22, 27, and 28 all over $400
• Median day estimated at $130-140

After limits (7-day period March 30 – April 5):

• Total spend: $361.56
• Average daily usage: ~$51.65/day
• User hit their weekly limit with this reduced usage

Workflow Impact

The user reports having to "very significantly change the way I work" and has:

• Used Sonnet
• Installed Codex and used it once
• Estimated needing "four 20x Max plans to code like I used to code"

The user notes that while some reports of limits might be due to misunderstanding token usage, their data shows a clear change in available capacity.
