# Calculating Allocations

During the [Burn Window](../../launch-events/burn-window) for an IDO, if you're [KYC-approved](../../launch-events/kyc-process), you can burn any amount of Hydrazine  ($N2H4) to secure an allocation.

There is no minimum required amount of $N2H4 to burn. IDO allocation size is directly and linearly proportional to the amount of Hydrazine applied for that given IDO. Each contributing wallet is capped at a certain percentage of the total IDO pool. This percentage will be visible on the IDO page.

#### The process:

1. Shortly before the Burn Window opens, a [maximum amount](../../terminology#max-hydrazine) of Hydrazine that can be burned for this IDO is set based on the total $N2H4 supply at the time. This is how we're able to calculate individual caps.
2. During the Burn Window, eligible users can burn $N2H4 up to their individual cap to register for the IDO.
3. When the Burn Window closes, allocations are calculated proportionally to the amount of $N2H4 burned by each wallet. If you burn 1% of the $N2H4 contributed during a Burn Window, for example, you'll be able to purchase 1% of the total IDO pool.

If the maximum amount of $N2H4 burned by all users is not reached, each contributing wallet secures a larger allocation proportionally.
