fal.ai Cost Calculator
Pick a fal.ai image model — FLUX 3, FLUX 2 / Flash, FLUX.1 dev / schnell, Z Image Turbo (per megapixel) or Nano Banana, Nano Banana 2 / Pro, Seedream V4.5 / 5.0 Pro, Fibo 2.0 Edit, Bria RMBG (per image) — enter kept images per month, megapixels per image and takes per kept image, and get cost per kept image and per month. Extra blocks price fal video models per second and serverless H100 GPU hours. Estimates only; fal.ai/pricing prevails.

Formula: per generation = $/megapixel × megapixels for FLUX / Z Image rows, or the flat $/image for per-image rows (megapixels ignored); per kept image = per generation × takes; monthly = kept × per kept. Seedream 5.0 Pro is listed by fal at $0.0675 "per unit" — treated here as 1 unit = 1 image. Video = $/s × seconds × takes × clips. Serverless GPUs bill per second while the runner is alive, including idle time. Skipped: opaque $1/unit rows (GPT Image 2, Nano Banana 2.1 / 2 Lite) and per-token Seedance rows.

How it works
- How does fal.ai price image generation?
- fal.ai bills either per image or per megapixel. Per image: Nano Banana $0.0398, Nano Banana 2 $0.08, Nano Banana Pro $0.15, Seedream V4.5 $0.04, Fibo 2.0 Edit $0.04, Bria RMBG 2.0 $0.018. Per megapixel: FLUX 3 Image $0.048, FLUX 2 $0.012, FLUX 2 Flash $0.005, FLUX.1 dev $0.025 (LoRA $0.035), FLUX.1 schnell $0.003, Z Image Turbo $0.005.
- How many megapixels is a 1024×1024 image?
- 1024 × 1024 = 1,048,576 pixels, about 1 megapixel, so the default here is 1. A 2048 × 2048 image is about 4 MP and costs 4× on per-megapixel models; per-image models ignore megapixels.
- What does Seedream 5.0 Pro cost?
- fal lists Seedream 5.0 Pro at $0.0675 per unit. This calculator treats 1 unit as 1 image; check your fal usage page if your requests consume more units.
- Which fal rows are not included?
- Rows priced in opaque $1 units (GPT Image 2, Nano Banana 2.1 and Nano Banana 2 Lite) and per-token Seedance video rows are skipped, because their cost per image or second can't be derived from the pricing page alone.
- How are fal video and GPUs billed?
- Video models bill per second of output: PixVerse V6 $0.005, MiniMax H3 Turbo $0.025 / Max $0.05, Grok Imagine Video $0.05, Kling 2.6 / 2.5 turbo pro $0.07, FLUX 3 Max $0.085, Kling v3 / O3 $0.14. Serverless H100 GPUs list at $4.50/h (as low as $2.49/h) and bill per second while the runner is alive, idle included.
