Fortnite Sprite Drop Rate Calculator

Enter your Sprite Chest attempts and see the chance of at least one drop.

Formula

The calculator uses: chance = 1 - (1 - drop rate) ^ attempts. It is probability math, not a guarantee.

How to read the result

The percentage is the chance of at least one drop across all the chests you entered, assuming each chest is independent and the rate stays constant. It is not the chance on your next chest. A 50% result means half of similar runs would see a drop by that point; it does not mean every second run pays out.

What the math does not promise

• There is no pity timer. A dry streak does not increase the next chest's chance.
• Reported rates are third-party estimates, not an Epic Games confirmation.
• Hotfixes can change chest pools and rates. Re-check after a patch.
• Chest type matters. A Sprite Chest is not the same as a normal chest or a rare chest.

Quick answers

Which rate should I enter?

Pick the Sprite from the list. The calculator uses the reported per-chest rate shown in the database. If an entry says "Rate not confirmed", it is not available for calculation.

Why does 100 chests at 0.03% show about 3%?

Because the chance compounds across attempts: 1 - (1 - 0.0003)^100 ≈ 2.96%. It still does not guarantee a drop.

Can I use this for other games?

The formula is generic, but the Sprite list and rates are specific to Fortnite. Use the full calculator link if you want to compare Sprites side by side.
