What does it cost to scale a Laravel SaaS?

Scaling cost has two components: engineering and infrastructure. Engineering for ongoing development and scaling typically runs $8,000 to $30,000 per month for a dedicated team, depending on team size. Infrastructure (hosting, database, Redis, CDN, monitoring) typically runs $500 to $5,000 per month at early scale and grows with usage. A well architected Laravel SaaS using Octane, Horizon, and read replicas scales efficiently, so infrastructure cost per user typically falls as you grow. The larger ongoing cost is almost always engineering, not hosting.
