AI consulting costs vary widely depending on the consultant’s experience, project complexity, and engagement type. Independent freelance AI consultants typically charge between $100 and $350 per hour, while senior specialists with deep expertise in machine learning or large language models can command $300 to $500 or more per hour.
Boutique AI consulting firms generally charge between $150 and $500 per hour, depending on the scope of work. Large global consulting firms like Accenture, Deloitte, or McKinsey can charge significantly more, with project-based fees ranging from $50,000 to several million dollars for enterprise-scale engagements. Many consultants also offer fixed-price project packages or monthly retainer arrangements, which can be more cost-effective for businesses with ongoing AI development needs.
