AI Content Cost Calculator
This free AI content cost calculator estimates what one SEO article really costs. Pick a model, set the article length and monthly volume, and it shows your cost per article and per month using your own OpenRouter API key — usually a few cents, not the dollars per-word tools charge.
Key takeaways
- A 2,000-word AI article typically costs $0.005–$0.08 with your own OpenRouter key.
- Bring-your-own-key pricing is usually 90%+ cheaper than per-word subscription writers.
- DeepSeek V4 Flash and Gemini Flash are the cheapest strong options for bulk drafts.
How much does one AI article actually cost?
With a bring-your-own-key setup, a 2,000-word article typically costs between $0.005 and $0.08 depending on the model. Fast models like DeepSeek V4 Flash or Gemini Flash sit at the low end; flagship models like GPT-5.5 or Claude Opus cost more but are still cents, not dollars.
| Model | Approx. cost / 2,000 words | Best for |
|---|---|---|
| Gemini 3.1 Flash Lite | ~$0.006 | Cheapest bulk drafts |
| DeepSeek V4 Flash | ~$0.008 | Bulk drafts, great value |
| Gemini 3.5 Flash | ~$0.017 | Balanced quality |
| GPT-5.5 | ~$0.34 | Flagship polish |
| Claude Opus 4.8 | ~$0.68 | Premium long-form |
Subscription AI writers hide this by charging per word or per credit, marking the underlying token cost up many times over. This calculator shows the raw model cost so you can compare honestly.
Why is bring-your-own-key so much cheaper?
When you pay a fixed monthly SaaS fee for AI content, you pay for the vendor's margin on every word. With a bring-your-own-key model you pay OpenRouter the wholesale token price directly and the platform only orchestrates generation and publishing.
nativeWP is an AI content automation platform for WordPress that bulk-generates SEO articles with your own OpenRouter API key and auto-publishes or schedules them to WordPress and Shopify. Because you connect your own key, the AI cost stays at wholesale even as you scale to hundreds of articles.
How to read your result
- Cost per article — input tokens (your prompt) plus output tokens (the article) at the model's price.
- Monthly cost — cost per article × articles per month.
- Vs a per-word tool — the same volume priced at a typical $0.01–0.03 per word so you can see the gap.
Frequently asked questions
- Is this AI content cost calculator free?
- Yes. It runs entirely in your browser, needs no login, and stores nothing. Estimates are based on published OpenRouter token prices.
- How accurate are the estimates?
- They are close approximations using each model's per-million-token price and a typical prompt-to-article token ratio. Real cost varies slightly with prompt length and output length.
- What is the cheapest model for bulk articles?
- Fast, low-cost models such as DeepSeek V4 Flash and Gemini Flash Lite generate solid SEO drafts for a fraction of a cent to a few cents per article, which is why they are recommended for bulk generation.
- Do I need an OpenRouter account to use nativeWP?
- To generate content in nativeWP you add your own OpenRouter API key once in Settings. That key is what keeps your per-article cost at wholesale rates.
