Why a calculator instead of an article
Claude's usage limits moved from a simple 5-hour window to 5-hour plus weekly caps; Copilot replaced premium requests with a credit wallet in June 2026; Cursor has repriced twice; OpenAI added Go and split Pro into 5x and 20x. Anything written down about "what it costs" is a snapshot. A calculator with a visible check date is a snapshot too — but one we can update in five minutes when a vendor moves, and one that does your specific arithmetic instead of a generic example.
Three things that matter more than the plan
Context size. Every AI coding tool resends your whole conversation on every request. Clearing between tasks is the difference between the top and bottom of every usage range. Model choice. Sonnet-class models handle most coding; frontier models cost 2.5–5× more per token and draw weekly limits proportionally faster. Caching. Stable prompts are served at a tenth of the price; anything that changes the system prompt on every call throws that away.
