AI marketing costs split across tooling, AI-augmented agencies, and internal time. Here is the realistic 2026 budget for B2B teams at each stage, and where the money actually goes.
A solo marketer's AI stack costs $50 to $200 per month. A mid-market B2B marketing team's AI stack costs $300 to $1,500 per month. An AI-augmented marketing agency runs $5,000 to $30,000 per month. Most teams overspend on tools and underspend on the time to learn them.
