Percentage Calculator
A drop rate like 0.02% doesn't feel like anything until you translate it. Enter any rate and this tool shows what it means as odds, as expected pulls per 100 packs, as days of grinding, and as confidence thresholds.

What does this rate really mean?
Enter any drop rate or pick a preset. You'll get five human framings so the percent stops feeling abstract.
%
As a percentage
0.02%
The raw per-pack chance. Every pack rolls the dice at this rate.
As a fraction
1 in 5,000
Long-run average: one pull per this many packs over thousands of trials. Not a guarantee on any given run.
Expected pulls per 100 packs
≈ 0.02 pulls · 1.98% chance at ≥ 1
The expected count across a 100-pack run, and your cumulative chance of seeing at least one.
Per daily grind
50% in ~139 days · 90% in ~461 days
Assuming you hit the 500-token daily cap (25 packs/day at this cost).
Thresholds
50% → 3,466 packs·90% → 11,512·99% → 23,024
Token cost at 90%: 230,240
Every framing uses
P(≥1) = 1 − (1 − p)^N on the back end. See the drop-rates guide for the full derivation, or the probability calculator to pick a specific Blook instead of a rate.When to use each tool
