This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Build An Ant Empire session. It will not click the shop.
Drop probability
At least one keeper roll
Estimate the chance of seeing at least one keeper while you roll at the Ant Queen. Enter the chance from your own board. This does not read your account, and it is not an official drop table.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
The 10 percent default is a blank example, not an Egg Luck rate. Public odds were not published. If the Ant Queen board shows a percent, type that number. The result is the chance of at least one success across independent rolls.
Material planner
Cash still needed
See how much Cash is still missing for a shop item or a number of identical purchases. Use the price shown in your current server.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Missing cash equals price per purchase times quantity, minus the cash you already have. The 1,000,000 default is the published Leaf Mutation Potion cash price, used only as an example. Replace it with the board or shop price you are saving for.
Upgrade payback
Upgrade payback
Estimate how many of your own sell cycles a Cash purchase needs before it pays back, and how many minutes that takes.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Demo inputs only. Read the next upgrade price in game, time one of your own collect-and-sell trips, and estimate how much extra Cash that upgrade adds per trip. Do not treat 1,000 Cash as a game rate.
Mutation value
Mutation value
Compare a mutation multiplier against a base value you enter. Guaranteed potions and random event mutations use different chances.
Expected value per crop = base value × (chance × multiplier + 1 − chance).
Shop potions are targeted and persistent, so 100 percent with 1.35 matches a guaranteed Leaf potion on a base value you type. Use 1.75 Bubblegum, 2 Candy, 2.25 Rainbow, 3 Petal, or 5 Starlight. Candy Rain and other random mutation events do not have a published chance. Do not leave 100 percent in place for those.
