The math, without the myth
More attempts raise your cumulative chance—not the luck of the next chest.
The normal preset uses a 1 in 137,500 per-chest rate. Each opening is modeled as an independent attempt. No pity counter, guaranteed drop, route bonus, or party bonus is assumed.
Use Normal unless an active event explicitly states a 1.5× or 2× chest drop boost. A boost changes the model, not your saved count.
A 50% cumulative chance is not a promise. It means half of many players following the same independent model would see at least one hit by then.
Cumulative chance of at least one token
1 − (1 − p)n
Here, p is the selected chance per chest and n is the number of chests tracked.
| Chests | Normal | 1.5× event | 2× event |
|---|---|---|---|
| 100 | 0.073% | 0.109% | 0.145% |
| 500 | 0.363% | 0.544% | 0.725% |
| 1,000 | 0.725% | 1.085% | 1.444% |
| 5,000 | 3.571% | 5.308% | 7.015% |

Quick answers
Fortnite chest counter FAQ
Does Fortnite have a built-in chest counter?
No season-wide chest total is shown to players. This tool records each opening manually and keeps the total in your browser.
Does opening more chests make the next chest luckier?
No. Each chest is modeled as an independent roll at the selected rate. More attempts improve the chance that at least one attempt succeeds, but the next individual chest keeps the same rate.
Does the counter guarantee a Pirate Shop Access token?
No. It is a tracker and probability calculator, not a token finder. Even a very large count cannot guarantee a random result when every attempt is independent.
Where is my chest count saved?
It is saved in local browser storage on this device. There is no login and the total is not uploaded. Use the backup button before clearing site data.
Can I count a full match at once?
Yes. Use +5, +10, or +25 after a match. You can also tap Undo or subtract one if you make a mistake.
Can I use it on a phone while playing?
Yes. The counter is designed mobile-first, has a large tap target, and can work offline after a successful first visit.
