Pikmin Bloom calculators

Which Pikmin Bloom calculator do you need?

Reach for the squad calculator when the question is about your own Pikmin: which ones to bring, how strong the squad is against one particular mushroom, and whether your level even lets you take it on. Reach for the star calculator when a group is involved — it adds every player's attack together and projects the rating the battle will finish with. The regrowth countdown answers the simplest question of all: when the day's mushrooms come back.

All three run on the same engine and the same sourced numbers, so a squad you build in one can be carried into the next with a single tap and the figures will agree.

How our calculators work

Attack power: where every result starts

A Pikmin's attack is a sum. Its type sets a base value between 2 and 6; maturity, Decor, friendship hearts and event decor each add a bonus on top; and the mushroom you pick adds one more, the type matchup. That last term swings hardest: +12 for a colour match on a regular mushroom, +100 for the correct type on a special one — where every other type does no damage at all. Add up the squad and you have its attack power.

The attack power formula, term by term

From attack power to a star rating

How long a battle lasts is the mushroom's health divided by everyone's combined attack, times 100. More attack means a faster finish, and the finish time is what earns stars: one for completing at all, more for finishing fast. The star calculator adds up a group's attack and projects the rating for you; each tier raises the reward bonus, from 5% up to 20%.

How star ratings work

Can you join the battle at all?

Battles unlock at level 8. From there your level caps your squad — 10 Pikmin at first, 40 from level 20 — and every mushroom size sets a minimum of its own. A giant will not start with fewer than 20, so below level 12 you cannot open one however strong your Pikmin are. Without tickets, 5 players can share a mushroom.

Squad size by level and by mushroom size

When a result doesn't match the game

Every value the calculators use comes from a cited source, and the date it was last checked is shown at the bottom of this page. When a result and the game disagree, the cause is usually an input: one heart or one maturity stage out on a handful of rows adds up across a whole squad. A group that trickled in late also finishes slower than its combined attack suggests.

Star ratings carry one more caveat: the time limits behind them are confirmed on one mushroom and assumed for the rest, so every rating is labelled an estimate. Game balance can also shift in a patch — if a number looks wrong, tell us and we will re-check it.
