Automatic-rate rule
A calculator rate is prefilled only when a dated official public source defines one comparable unit. The model, unit, currency and review date stay visible.
Official sources covered
Runway, Google Veo and Gemini Image, OpenAI Sora legacy, Higgsfield, Luma, Midjourney, Ideogram, ElevenLabs, MiniMax Hailuo, Google Lyria and Suno. Every configuration links to its primary source.
Account-specific pricing
Kling account, region and promotion-dependent figures are not presented as universal prices. The calculator requests the exact credits-per-second value shown before generation instead of guessing.
