Chest odds tracker
7.5× is a published gold outfit reference; individual Treasure Hours sessions can differ. Pirate Shop Access is shown at the normal-match rate.
Normal-match model
Weekly Gold Outfit · Normal match
Model only: N independent openings for one unowned reward at the selected rate. Not your actual account odds or a guarantee.
Theoretical expected awards:
Changing the model treats all N openings at the selected rate. It does not identify past Treasure Hours openings or change your saved counts.
How to read this estimate
The cumulative estimate is 1 − (1 − p)N. Expected awards are N × p, not the number of rewards you have won. N × p is also a small-count approximation to the cumulative probability, not an exact equality. Your log may span different weeks, chest types and boosted sessions. Epic has not published the full random process or separate odds for each chest type. More openings do not improve the next chest's base rate. The 7.5× gold multiplier is a reference scenario; a specific Treasure Hours session can differ.
How to use the chest counter
Tap +1 after opening a chest. Use +5 or +10 to add a batch, and −1 to correct a mistake. The three counts stay separate; Total opened adds them together.
This log has no reward target or guaranteed winning count. It does not read the game's quests. More openings do not increase the next chest's per-chest drop rate.
To clear the log, tap Reset all, then confirm with a second tap within three seconds. Cancel or let the timer expire to keep your counts.
Frequently asked questions
Does CHESTMAP sync with Fortnite?
No. You enter the counts yourself. The site does not read your account, matches or quest history.
What happens after 1,000 chests?
Your manual count keeps increasing. There is no guaranteed reward at 1,000 openings. Destructoid reports an in-game tracking cap of 1,000 per chest type; a quest counter is not a reward guarantee or this site's total.
Chest-tracking report ↗Does the model include Treasure Hours?
You can select a 7.5× reference scenario for Weekly Gold Outfit. It treats all N openings at that rate; it does not identify which past openings happened during Treasure Hours. Pirate Shop Access uses its normal-match rate. A log mixing weeks or boosted sessions cannot measure your actual account odds.
