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 Encarotia's Boutique
The calculator opens on 2,000 Encarotia's Skeins at 0.1% a draw. That is about a 9.5% chance in 100 draws, 39% in 500 and 63% in 1,000. An even chance takes 693 draws, and 90% takes 2,302. The Noonbora Outfit Set has the same 0.1% rate, so the same numbers apply to it; if you'd be happy with either one, the combined 0.2% halves the wait to 347 draws for an even chance.
The Noonbora outfit chests are 0.1875% each, but there are eight of them. For one particular chest you need 370 draws for an even chance. For any of the eight (1.5% together), 46 draws give an even chance and 100 draws about 78%. The Ornament Selection Chest at 2% takes 35 draws.
Pearl Abyss doesn't publish what a Boutique draw costs in Pearls, so the calculator gives chances and draw counts but no price per draw.
Mobile Pearls
These are App Store UK Pearls for the mobile game, not the PC or console Pearls sold for Black Desert. Pack size barely changes the price: about £2.48 per 100 in the 40-Pearl pack and £2.43 per 100 in the 4,115 pack, so buying in bulk saves very little. The cheapest-packs tool above is more useful for avoiding leftover Pearls than for saving money.
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 Mobile 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.
