Claude Code subagents can significantly impact token usage, with some users reporting a 40% reduction in billing by offloading tasks, while others have encountered high costs due to parallel subagent execution. A single subagent can incur substantial token usage, ranging from 12,427 to 84,000 tokens, before any code is written, due to its independent context window and startup payload. Developers must carefully consider the trade-off between the subagent's startup cost and the potential savings from keeping the main context window lean, especially for tasks that would otherwise generate numerous tokens.

IMPACT Understanding subagent token costs is crucial for developers using Claude Code to manage expenses and optimize workflows.
RANK_REASON Article discusses token usage and cost implications of a specific feature (subagents) within an existing product (Claude Code), rather than a new release or fundamental research.
