From drop to last chest
How to use the Fortnite chest counter
One tap per chest. A running total you can pick up next time.
Catch up in batches.
Count after the match with +5, +10, or a custom batch. Miscounted? Subtract one or undo the last action.

Your browser saves as you go. Start a new session to keep the overall total, or export a JSON record for your own notes.

Chest reward probability calculator
Explore a possible reward chance across multiple chests, using assumptions you control.
Example assumptions, not official drop rates. The default 5% is hypothetical. This site does not publish a verified current Fortnite loot table. Chest types, modes, patches, and rewards can have different rules.
For a chosen reward with probability p per chest and n independent openings, the chance of getting it at least once is:
1 − (1 − p)n
For the example 5% rate, 10 chests gives 40.13%, 20 gives 64.15%, and 50 gives 92.31%. Your next chest still has the same assumed 5% chance.

Local counting and probability modeling serve different purposes. Neither is a live game feed.
| Feature | What it tells you | Where the data comes from |
|---|---|---|
| Session counter | Chests you have added this run | Your taps and manual batches |
| Total across sessions | Recorded openings since your last full reset | Your saved browser record |
| Goal progress | Your count compared with a personal target | The target you enter |
| Reward probability | A mathematical chance under fixed assumptions | Your chosen per-chest chance, not a game API |
Data and update policy. Counter data is entered by you. Probability results are calculated in your browser from the formula above; all numerical examples use a hypothetical 5% rate. No Fortnite account, game telemetry, or season-specific drop-rate feed is connected. Tool and editorial content last reviewed .

Good questions, straight answers
Fortnite chest counter FAQ
How do I use a Fortnite chest counter?
Open this page on a phone or second screen and tap Add chest after each chest you open. Use +5, +10, or a custom batch to catch up after a match. The counter is manual and does not connect to Fortnite.
Does this Fortnite chest counter save my progress?
Yes, when browser storage is available. Counts, your goal, custom batch size, and probability settings are saved in localStorage on this browser and device. Clearing site data or using a different browser will not preserve that record.
Can I count Fortnite chests on my phone?
Yes. Large buttons and a responsive layout work on mobile browsers. Keep the page open on your phone while you play on another device. No account or app installation is required.
Can it automatically track opened chests in Fortnite?
No. Loot Ledger is a manual chest tracker. It does not read your game, Epic account, match history, or quest progress. Always check the in-game quest display when tracking a specific objective.
How do I add several chests at once?
Tap +5 or +10, or enter a whole number from 1 to 10,000 in Custom batch and select Add batch. Undo reverses the most recent counting action, including a batch, a new session, or a reset.
Are the chest loot odds official Fortnite drop rates?
No. The calculator starts with a hypothetical 5% chance and 20 chests to demonstrate probability. Enter your own per-chest probability. No current season loot table, rarity distribution, or official reward rate is supplied.
Does opening more chests guarantee a rare reward?
No. The calculator assumes independent chests with a fixed chance per chest. At a chance below 100%, any finite number of chests can still yield no desired reward. An expected reward count is an average, not a promise.
What is the difference between a new session and resetting all counts?
New session clears the current session and keeps the total across sessions. Reset all counts clears both counts and returns the session number to one. Either action can be immediately reversed with Undo until your next counting action; the undo record is not saved across reloads.
