Fortnite Pirate Shop Token Drop Rate Calculator
Test a hypothetical token chance against your chest count: see the probability of at least one find, the expected chests and the chests a target confidence needs.

Hypothetical drop chance
Hypothetical scenario only — not an official Fortnite drop rate. The field starts empty on purpose so no default can be mistaken for a real chance.
Each preset is a hypothetical scenario chosen for illustration. None of them is an Epic Games figure.
Enter a hypothetical chance to see a result. The calculator will not guess one for you.
Epic has not published a Pirate Shop Token drop rate. Every number here comes from the percentage you enter, and the model assumes independent chests with no pity system.
How to use this tool
- 1Enter a hypothetical chance, or start from a labelled scenario preset.
- 2Set how many chests you plan to open; the probability updates as you type.
- 3Add chests per match and matches per hour to turn chests into play time.
- 4Raise the target confidence to see how many chests a 90% or 99% chance would need.
How the calculation works
p is your hypothetical per-chest chance, n is the number of chests and T is the target confidence. The engine uses log1p and expm1 so tiny probabilities keep their precision.
P(at least one) = 1 - (1 - p)^n E[N] = 1 / p n_target = ceil( ln(1 - T) / ln(1 - p) )
Assumptions and limits
- Every chest is an independent attempt with the same chance.
- No pity counter, guaranteed chest, loot rotation or party bonus is modelled.
- The chance is invented by you; it is not an Epic Games figure.
Worked example
200 chests at a hypothetical 0.01%
A player assumes a 0.01% chance per chest, opens 200 chests at 10 chests per match and 4 matches per hour, and wants 90% confidence.
- 01Convert 0.01% to p = 0.0001 and use n = 200.
- 02Compute 1 − (1 − 0.0001)^200 ≈ 0.0198, so about 2.0%.
- 03Expected chests = 1 / 0.0001 = 10,000.
- 04For 90% confidence, ceil(ln(0.1) / ln(0.9999)) = 23,025 chests.
- 05200 chests is 20 matches, which is 5 hours at 4 matches per hour.
Result: At a hypothetical 0.01% per chest, 200 chests give about a 2.0% chance. A 90% chance would need 23,025 chests, roughly 576 hours at this pace.
- · 0.01% is a scenario chosen for the example, not a Fortnite drop rate.
- · Chest openings are independent and the chance never changes.
Frequently asked questions
Is this the official Fortnite drop rate?
No. Epic has not published a chance for the Pirate Shop Token. Every percentage here is a hypothetical value you type in, and the presets are labelled as scenarios rather than game data.
Does opening more chests guarantee a token?
No. Under an independent model the chance approaches 100% but never reaches it, and a real game may use a different distribution. A 99% confidence still leaves one player in a hundred empty-handed.
Can I model a full squad?
Only by changing the chance yourself. One chest can grant access to the whole party, so squad play changes how a find is shared, not the per-chest chance. The calculator does not multiply a party size into the rate.
Why is the expected number lower than the 90% target?
The expected value 1 / p is a long-run average pulled down by early finds. Reaching 90% confidence needs more attempts because the unlucky tail is long.
