AI Content Generation Cost vs Agency Calculator
Compare the true per-article cost of AI content generation against freelance writers and content agencies. Includes LLM tokens, editor review time, fact-checking, and SEO optimization — the hidden costs vendors omit from glossy AI ROI decks.
The Hidden Cost of AI Content
Raw LLM cost per article is genuinely cheap — USD 0.05-0.30 on frontier models for a 1500-word draft. But shipped, on-brand, fact-checked content is not cheap. The hidden costs: prompt engineering time, RAG context preparation, human editor review (usually 30-60 minutes per article), fact-checking (links, statistics, quotes), SEO optimization, image sourcing or generation, and CMS publishing. Real per-article AI cost lands at USD 25-90 once you load editor time.
True AI Article Cost
AI Cost per Article = Token Cost + (Editor Time × Hourly Rate) + Image Cost + Tool Subscription / Articles per Month
Agency Cost = Articles × Agency Per-Article Rate
Agency and Freelance Benchmark Rates
Per 2025 ClearVoice and Verblio benchmarks: freelance writers charge USD 0.10-0.50 per word (a 1500-word piece is USD 150-750). Content agencies charge USD 200-600 per polished article including outline, draft, edit, and one revision. High-end B2B agencies for thought leadership charge USD 800-3000 per article with subject-matter expert interviews. White-label content mills go as low as USD 30-80 per article but quality is unusable for serious B2B brands.
Where AI Wins and Loses
AI wins decisively on: high-volume product comparison content, basic how-to articles, programmatic SEO templates, FAQ pages, meta descriptions, and content updates. AI loses on: original research, executive thought leadership, customer case studies (interviews required), opinionated commentary, and anything requiring brand voice nuance. Best-in-class teams run hybrid: AI handles 60-70 percent of total volume while humans handle the high-value 30-40 percent that drives backlinks and brand authority.
How to Build the Business Case
Calculate both scenarios at realistic monthly volume (not your dream volume). Include a 30 percent editor time overhead on the AI side (most teams forget this). The honest answer is usually that AI lowers blended per-article cost by 50-80 percent at high volume (200+ articles/month) and 30-50 percent at low volume (under 50/month). At under 10 articles/month, the tool subscriptions often kill AI ROI — stick with freelance.
