Official rules, visible assumptions
Apex Legends Calculators
These tools separate what EA publishes from what a player must estimate. Heirloom calculations use one global disclosed minimum rate, explicit eligible-pack exclusions, and no invented account modifiers.
Pack Probability Calculator
EA's disclosed 0.045% minimum, a lower-bound cumulative estimate, and the 500 eligible-pack diagnostic.
Heirloom Guarantee Tracker
Keep an eligible-pack estimate separate from event/direct unlocks and your current Shards balance.
Battle Pass Pace Planner
Compare your observed level pace with a target using current in-game values you enter yourself.
Published Heirloom rules used across the tools
- EA discloses a 0.045% minimum Heirloom Shards rate.
- Eligible players should not open more than 500 eligible packs without Bonus Heirloom Shards.
- EA excludes several event and replacement-item pack categories from the guarantee counter.
- Eligibility can pause when the account owns all available base Mythics or already holds enough Shards.

What LootCalc cannot know
LootCalc cannot read a hidden account pack counter, determine the eligibility of an unlabeled historical reward, or reconstruct a cross-progression counter from two platform histories. The tools ask for user inputs and keep those uncertainties visible instead of presenting them as official account data.
