# Fraktion Price Index Formula

The Current Price (CP) of a fraction a Content *i* with a rarity *j* is recalculated every week depending on $$\gamma\_k$$ : 

$$
CP\_{ij}(w)=Max \bigg(, (\gamma\_j)^2 \times CP\_{ij}(w-1), , 0.8\times CP\_{ij}(0)\bigg)
$$

$$w$$: current week\
$$\gamma\_j(w)$$***:*** gravity coefficient

Creators can choose to supply their fraction at once or within a defined period of time. The Current Price is always at the moment of the minting. 

{% hint style="danger" %}
The Current Price is always at the time of the minting. If a Fraktion is supply at week $$w$$ but minted at week $$w+2$$, the price will be $$CP\_{ij}(w+2)$$.
{% endhint %}

If the number of Fraktions minted is equal to the number of fractions supplied, THEN the price depends only on the consumption.
