It is pure math
The paint seed feeds Valve's own pattern-placement RNG. Each seed produces a fixed rotation, and that rotation maps to a fade percentage between 80% and 100%. Same seed, same result, every time — no screenshots, no guessing.

How this calculator works
Per-weapon ranges
Every Fade weapon has its own pattern config, so seed 412 is a 100% AWP but something else on a Glock. The calculator uses each weapon's exact offsets and rotation range, including the reversed weapons (AWP, Karambit, MP7, Talon).
Runs on your device
No API, no account, no prices pulled — the whole calculation runs locally in your browser. Enter a seed from any inspect link or listing and read its fade instantly.
Fade calculator FAQ
How is fade percentage calculated?
The paint seed determines the pattern's rotation via Valve's placement algorithm. That rotation is ranked against all seeds for that weapon and mapped to a percentage from 80% (worst) to 100% (best, "full fade"). It is fully deterministic — the same seed is always the same fade.
Where do I find a skin's paint seed?
Use the in-game inspect option or an inspect link, and marketplace listings usually state the seed and pattern for Fade skins. Enter that number here to read the exact fade percentage.
Is a higher fade percentage always worth more?
Within the same skin, yes — a 100% consistently prices above a 90%, and full fades carry the biggest premium. The size of the premium varies by weapon and demand.
Does wear or float affect the fade percentage?
No. Fade percentage comes only from the paint seed, not the float. Most Fade skins sit in low float ranges (Factory New), so the seed is what collectors chase.
