How to Use the Apex Pack Calculator
This calculator estimates the number of Apex Packs you need to open to reach a target number of Heirloom Shards, considering the 1% drop rate and the 500-pack pity system.
- Enter Desired Heirloom Shards – The total shards you want (e.g., 150 for one heirloom).
- Enter Packs Already Opened – Your lifetime pack count (from stats or trackers).
- Enter Current Shards – The shards you already have.
- Enter Current Pity Count – A number from 0 to 499 representing how many packs since your last heirloom shard drop (or since you started tracking).
- Click "Calculate" – The result shows the estimated packs needed and a breakdown.
Note: The calculator uses random simulation, so results are estimates. The pity system guarantees shards every 500 packs if not obtained earlier.

Frequently Asked Questions
Heirloom Shards are obtained from Apex Packs with a 1% chance per pack, and a guaranteed drop every 500 packs (pity system). Each drop gives 150 shards.
If you open 499 packs without getting Heirloom Shards, the 500th pack is guaranteed to contain them. This calculator accounts for that.
Due to the random nature of pack openings, the result is an estimate based on average probability. Actual results may vary.
