Bank Deposit Interest Calculator

Project your CrystalGold return from a Bank Stronghold deposit. Rates scale with stronghold level and term length. Deposits are locked for the full term — no early withdrawal.

Deposit amount (CrystalGold) Max 6,000 per deposit · up to 3 deposits/day

Bank Stronghold level

Term length

How Bank deposits work

Deposit limits: 6,000 CrystalGold per deposit, up to 3 deposits per day (max 15 active at once).

Lock-up: Deposits are locked for the full term — no early withdrawal.

Plunder risk: If your alliance loses the bank, deposits are still honoured (unless plundered during the 60-minute capture window). Plunder caps at 1,000 CrystalGold per attacking squad, 12 turns max (120,000 total).

Effective APY: Annualised percentage yield — shows what your return would look like if compounded over a full year at the same rate. 5-day deposits at high levels can exceed 2,000% APY.

Bank Plunder Calculator

Estimate your CrystalGold yield from plundering a Bank Stronghold. Each squad yields 1,000 CrystalGold per turn, capped at 12 turns (120,000 CrystalGold max per player per bank).

Squads to send 1,000 CrystalGold per squad per turn

Turns already plundered this bank 0–12 turns (12 = fully plundered)

How Bank plunder works

Yield: 1,000 CrystalGold per squad per turn.

Turn cap: Each player can plunder a given bank at most 12 turns. After that the bank is fully plundered for that player.

Max yield: 120,000 CrystalGold per player per bank (e.g. 10 squads × 12 turns).

Remaining capacity: Shows how much CrystalGold you can still earn from this bank before hitting the cap.

Warzone Train Sale Calculator

Project your CrystalGold return from selling Whiskey on the Warzone Train (Premium Sale, Week 3+). Set your own asking price per Whiskey between 100 and 500 CrystalGold — up to 200 Whiskey per sale, 300 Whiskey per day.

Whiskey to sell Max 200 per sale

Asking price per Whiskey (CrystalGold) 100–500 CrystalGold per Whiskey

Whiskey already sold today 0–300 (daily cap across all sales)

How the Warzone Train works

Premium Sale: From Week 3, you set your own asking price (100–500 CrystalGold) for each Whiskey consignment, up to 200 Whiskey per sale.

Daily cap: 300 Whiskey per player per day, capping earnings at 150,000 CrystalGold/day if every sale clears at the maximum 500 CrystalGold price.

Plunder risk: Consigned Whiskey trades can be plundered by rival alliances while the train is en route.

Data note: The 100–500 CrystalGold/Whiskey Premium Sale band and daily caps are corroborated across multiple Season 5 guides. The earlier Week 2 "standard price" consignment system uses a predefined (non-player-set) rate that no source documents as a specific number, so this calculator models the Week 3+ Premium Sale mechanic.

Using the calculator

Work down the four steps: Target, Your Virus Resistance, Squads, Result. The bar at the top always shows the verdict, win chance, troop loss and your VR gap.
Each squad is checked on its own, not as a pooled rally total.
Bank Stronghold: every squad faces its own defender. Doom Elite: one shared target; once it falls, later squads are not needed. Zombie: cannot be rallied, so one squad only.
Advanced holds rarely needed settings: overrides, exact damage reduction, enemy type advantage, Protectors and teammate upgrades.
Use the Squads tab to keep a roster of members, heroes and alliances, and the Economy tab for the other planners.

Data confidence

Verified values were confirmed in real battles.
Guide-sourced values come from published Season 5 guides but are not yet confirmed in-game.

Export JSON downloads your edits; send the file to allies, who load it with Import JSON.

Reading the verdict

CLEARS means the squad beats the target; FAILS means it does not.
CLOSE, BARELY and BORDERLINE mean within about 10-15% of the line: it could go either way. Add a buff or more VR before attacking.
