What this tool provides

ChestTracker is a free, independent manual record-keeping utility. You are responsible for entering accurate counts and keeping backups. It does not provide Fortnite gameplay, automated tracking, rewards, V-Bucks, item redemption or account access.

Probability estimates

The calculator is a mathematical illustration based on the rate and number of eligible opens you enter. Its initial value is not an official drop rate. Results assume independent rolls at a constant rate and cannot predict a specific player’s reward. A high cumulative percentage never guarantees a drop.

Game information changes

Reward eligibility, rates and events can change. Follow current official game announcements. A user-created wishlist does not establish that a reward is currently available.

Local storage

Browser storage can be cleared, blocked or lost. Export a backup before switching browsers, domains or devices. This tool offers no recovery service for missing logs.

Independence and marks

ChestTracker is not affiliated with or endorsed by Epic Games. Fortnite is a trademark of Epic Games. No official endorsement or guarantee is implied.
