Your Account Data
This estimator is based on community research and player-submitted data. The official migration formula has never been publicly released. Tiers shift slightly by server group and season — treat borderline results as approximate.
How This Calculator Works
This tool answers one question: if State Migration opened tomorrow, which migration identity would the game hand you — Regular, Intermediate, Advanced or Elite? You paste in the four power values from Profile → Details, tell it which mod vehicle you run and whether T10 is unlocked, and it returns an estimated migration score in millions plus the tier that score falls into.
That tier is the thing that actually matters. Migration cost, which states you are allowed to enter, and how freely you can move all key off it — the score itself is just the number underneath. The tier ranges this tool uses are Regular below 20M, Intermediate up to 40M, Advanced up to 100M, and Elite above 100M.
How the game mechanic works
Migration score is a snapshot of account development, not of your army. Two things surprise people the first time they check. First, troop power is not part of it — burning troops before a migration window does nothing to your score. Second, the score is a high-water mark: it tracks the best values your account has ever reached and never falls back down. You cannot un-build your way into a cheaper tier.
The pieces that do move it are Hero Power and Mod Vehicle Power, with Building Power contributing a much smaller slice. In this tool's fit, hero power carries a weight of 1.2 and mod vehicle power 1.1, while building power comes in at 0.06 — that gap is why two players with identical HQ levels can sit two tiers apart. Tech Power is collected on the form for completeness but is not weighted in the current fit, because the player data we have does not show it moving the result on its own.
Two flat jumps sit on top of that. Unlocking T10 adds a fixed 16M-scale step, and running an EX Destroyer adds 43 — Hercules and standard Destroyer both add nothing. Those two switches together are worth more than most players' entire building tree, which is exactly why the calculator asks about them separately instead of folding them into a power number.
Where the data came from
The developers have never published the migration formula, so this is a fit, not a transcription. It was built by collecting matched pairs — a player's four power values from Profile → Details alongside the migration identity the game actually showed them during a live migration window — and solving for coefficients that reproduce those observed tiers. Every coefficient the tool uses lives in one file so it can be re-fitted when new data lands.
The reference sections below it (phases, requirements, timers, what changes when you move) are a different kind of data: those are read straight off the in-game migration panel by DXB KING — State 511, HQ35, T10 complete — and cross-checked against a second account before publishing. Where the fit and the panel disagree, the panel wins.
Treat a result near a tier boundary as a coin flip rather than a verdict. Thresholds shift slightly between seasons and server groups, and a score sitting within a million of a boundary can land either side of it on the day. If you need certainty, wait for the in-game panel during the migration window — it is the only authoritative source. Planning a move? The State Migration guide covers the rest of the process.
State Migration Reference
Everything from the in-game State Migration event, in one place — tier costs, phases, requirements and outcomes.
Migration Tiers & Pass Costs
| Tier | Migration Score | Migration Cost | Freedom |
|---|---|---|---|
| Elite | Over 100.0M | 50 passes | Invite / approval only |
| Advanced | 40.0M – 100.0M | 20 passes | Invite / application |
| Intermediate | 20.0M – 40.0M | 15 passes | Invite / application |
| Regular | 0 – 20.0M | 10 passes | Free migration |
Thresholds are set per migration event and shift with your server group's overall strength. Migration Score is built from Building, Tech, Hero and Mod Vehicle Power — and it tracks your highest-ever record, never decreasing.
The Three Phases
View available states and contact the Presidents of destinations you're eyeing. No applications yet — this is planning time.
Presidents invite survivors from other states, and your identity tier is locked in. Intermediate and above can also submit Special Immigration Applications.
Regular survivors move freely into any state with open Regular slots. Everyone else still needs an invite or an approved application.
Requirements & Timers
- Hold a Regular identity during Free Migration, or have received an invitation.
- Your Headquarters level meets the required minimum.
- HQ is not in combat and has no troops deployed outside.
- You are not the President of any state.
- You haven't already migrated during this event round.
- You are not part of any Alliance — leave it first.
