Tier ↔ Linked Domains Calculator

Scheme: “1-in-(G-1)”. Each group has G total domains → 1 linked + G-1 tier.

Forward (Find Tier + Total)

Group size G (e.g., 10 → 1 linked in 9 tier)

G ≥ 2. G = 10 means 1:9 (linked:tier).

Desired linked domains L

How many distinct linked domains you want.

Tier / Linked ratio

9 : 1

Required tier domains (T)

Total domains (D = L × G)

Formula

T = L × (G − 1)

Group size G

Total domains available D

Max linked (calculated)

Used tier ( = Lmax × (G − 1) )

Groups formed

Spare (leftover domains)

Check

D ≈ (Lmax × G) + spare
