How it works
Each pull is treated as independent, with the same chance every time. The chance of at least one drop in n pulls is 1 − (1 − p)n. With a guarantee on pull N, the chance is 100% from pull N, and the average number of pulls falls to (1 − (1 − p)N) ÷ p.
Some games also raise the rate a little in the pulls before the guarantee (soft pity). That isn't modelled here, so for those games the real average is a little lower than shown.
How pity works explains the maths in more detail.

Working it through for the Mystery Outfit Box
The calculator opens on the box's top result, ten Premium Outfit Boxes at 0.5% an opening. The chance of seeing it at least once is about 22% in 50 boxes, 39% in 100 and 63% in 200, the average. Half of all players will have it within 139 boxes; to be 90% sure you need 460. At the 1,300 PC Pearls a box from Pearl Abyss's June 2024 Pearl Shop pack, those 460 boxes come to 598,000 Pearls.
The seven Classic Outfit Boxes at 1% take 69 openings for an even chance, and a single Classic or Succession Classic Box (8% each) only 9. Pick those rows above to see the full curve.
The 2% result that gives three more Mystery Outfit Boxes doesn't change these numbers: count every box you open, including the free ones, as one opening.
Console Pearls
The Pearl packs above are the PlayStation Store UK prices, so they are console Pearls, a separate currency from the PC Pearls the box price is quoted in. Bigger packs are clearly cheaper here: 1,000 Pearls for £7.99 is about 80p per 100, against about 64p per 100 in the 13,850 pack.
Where these numbers come from
Rates are exactly as the publisher discloses them, with the source and the date we checked each one on the Black Desert page. We don't estimate rates a publisher hasn't published. Every rate publishers have disclosed, game by game, is in our Drop-rate index.
