Claude Code, an agentic coding tool run from a terminal, is not sold as a standalone subscription but is included in every paid Claude plan—Pro, Max, Team, and Enterprise—drawing from the same usage pool as the Claude chat app. Its pricing model can confuse users because it may switch to token-based API billing, producing a different invoice. Anthropic changed usage limits in the past year, most recently a per-session limit increase on May 6, 2026. The tutorial covers 13 steps, including installing Claude Code, confirming an Anthropic account, understanding subscription versus API/console billing, auditing workflow to estimate usage, choosing between Pro, Max 5x, and Max 20x plans, setting up billing in the Anthropic Console, understanding the five-hour session window and weekly limits, switching models to control cost, enabling prompt caching to cut token costs, setting up API/console billing for overflow, configuring Team or Enterprise billing, monitoring usage and spend, setting spend limits and budget alerts, and reviewing plans monthly. It also includes a budgeting example for a 5-person dev team, common pitfalls, troubleshooting for eight billing problems, and a comparison against GitHub Copilot and Cursor.
