True TCO requires accounting for every cost category over a five-year period: subscription fees, cloud infrastructure hosting, initial developer setup (typically 40-80 hours), ongoing maintenance hours, training and onboarding, plugin or platform update management, and the often-overlooked opportunity cost of tracking gaps during setup and migration. The most misleading metric is monthly subscription price—a $21/month tool requiring $12,000 in developer setup and $500/month in maintenance costs $42,000 over five years, not the $1,260 the subscription suggests.
