AI Coding Tools Real Cost: $200–$600/Month Per Engineer After Hidden Costs — Licensing Is Only 60–70% of TCO

A detailed cost analysis finds that AI coding tool spending per engineer ranges $200–$600/month when accounting for the full picture, despite vendors advertising $10–$20/month base prices. Licensing represents only 60–70% of true first-year costs, with the hidden 30–40% coming from integration labor, training overhead, and usage overages (especially token-based billing). Microsoft Research found productivity gains don't materialize until 11 weeks, with break-even at 12–18 months — a timeline most enterprise budgets don't plan for.
