When does jCodeMunch pay for itself?

Two modes. Your numbers. A screenshot-able answer. Builder license is a one-time $79; Anthropic Max 5× is $100 every month.

Your usage

A "lookup" = any time the agent reads code to answer something. 50–200 is typical for active dev work.

Honest math: The "Published Benchmark" mode uses our FastAPI retrieval test — 214,312 tokens vs ~480 tokens, which works out to roughly $1.08 saved per benchmark-style lookup at Claude Sonnet pricing. Real sessions vary wildly (most queries don't dump 200K tokens). The "Conservative" mode uses the per-iteration delta from our Vue+Firebase A/B test instead, which is closer to typical day-to-day work. Pick the mode that matches your skepticism level. Either way, payback lands in literally days of normal use.
