AI coding usage data

Most published figures for what AI coding costs are vendor estimates. These are measurements — token counts and API-equivalent costs computed by ccusage from developers' own local session logs, then submitted here. Free to use, CC BY 4.0, no key required.

Anthropic reports $150–$250 per developer per month. Across 1,039 developers who measure their own usage, the median is $1,391/month and 86% exceed $250.

Methodology and limits

  • —Figures are API-equivalent cost computed by ccusage from local session logs, not amounts actually billed. Most developers on the board pay a flat subscription, so this measures what their usage would cost at API list prices.
  • —The population self-selects: these are developers who chose to measure their own usage and publish it, which skews heavier than the average Claude Code user.
  • —One row per developer (their highest-cost submission), normalised to a 30-day month. Submissions covering fewer than 7 days are excluded because they extrapolate to meaningless monthly figures.
  • —Submissions are validated server-side; only aggregate totals are accepted, never code or prompts. Accounts signed in with GitHub carry a verified badge.
