# ClipCost > ClipCost (https://costperclip.com) calculates what an AI video actually costs per usable clip. It tracks verified pricing, credit rates, expiry traps and commercial/watermark rules for 12 AI video tools, checked against official pricing pages. Sticker price x (1 + retries) at the real price-per-credit is the core method: a generation is not a usable video. ClipCost is free to read for humans and agents. Pricing data is also available as machine-readable JSON (see below). Prices change often — always check the official pricing source linked for each tool before buying. ## Key pages - [Calculator](https://costperclip.com/#calculator): cost per usable finished video by tool, model, plan, duration and retries - [Compare](https://costperclip.com/compare.html): Runway vs Kling vs Pika vs Veo at 30s and 60s - [Kling credits explained](https://costperclip.com/kling-credits-explained.html): verified plan credits and expiry; per-generation rate unverified - [How much does 1 minute of AI video cost](https://costperclip.com/how-much-does-1-minute-of-ai-video-cost.html): 60s single-try vs usable on verified rates - [Cheapest AI video generator](https://costperclip.com/cheapest-ai-video-generator.html): ranked per usable clip, verified rates only - [FAQ](https://costperclip.com/faq.html): 1-minute AI video cost, cheapest generator, Kling credits, Runway vs Kling cost - [Newsletter — The Weekly Credit Check](https://costperclip.com/#newsletter): weekly email on price, credit and model changes ## Tools (verified pricing pages) - [Runway](https://costperclip.com/tools/runway.html) - [Kling AI](https://costperclip.com/tools/kling.html) - [Pika](https://costperclip.com/tools/pika.html) - [Veo 3.1 (Gemini API)](https://costperclip.com/tools/veo.html) - [Luma (Ray)](https://costperclip.com/tools/luma.html) - [HeyGen](https://costperclip.com/tools/heygen.html) - [Hedra](https://costperclip.com/tools/hedra.html) - [Descript](https://costperclip.com/tools/descript.html) - [OpusClip](https://costperclip.com/tools/opusclip.html) - [Seedance](https://costperclip.com/tools/seedance.html) - [MiniMax / Hailuo](https://costperclip.com/tools/minimax.html) - [Vidu](https://costperclip.com/tools/vidu.html) ## Machine-readable data - [pricing.json](https://costperclip.com/pricing.json): all 12 tools — plans (price/credits), model rates where verified, 5s/30s/60s cost examples where calculable, traps and notes, with per-tool official and pricing-source URLs.
