# What causes the milk percentage to rise?

In cookie clicker, what causes the milk percentage to rise?

I had a hundred percent, but now I have 106% and I have no idea where it came from. Now I also got the milk turned into raspberry juice and the value is up to 228%

The base amount of milk is 0%. The current formula for calculating milk is `milk = achievements / 25`. That means that for every achievement, you get 4% milk.

Are you sure 58 is the number shown in the stats page? I currently have 40 achievements, giving me 160% milk (as expected).

I have just discovered that not all achievements count. The August 27th update states:

due to popular demand, retired 5 achievements (the "reset your game" and "cheat" ones); they can still be unlocked, but do not count toward your total anymore.

If you hover over one of these achievements, it'll say [Shadow] in the tooltip. An example of this is:

Uncanny clicker ("Beat the clicking speed world record."):

I got this through using MouseKeys to sort of gain an advantage :P

This means that even though it's displayed in the stats page, it doesn't actually count when calculating milk %. Thus, even though I have 42 achievements, since one of them is a [Shadow] achievement, the game calculates my milk as 41 / 25 = 164%.

### More milk facts!

The text next to milk is just flavour text. When milk is less than 100%, it's simply plain milk. When it's at least 100% but less than 200%, it's chocolate milk. Otherwise, if it's at least 200%, it's raspberry juice.

Milk will only affect Cookies Per Second (CpS) if you have at least one kitten upgrade. The first one, Kitten helpers, is unlocked at 50% milk and adds a `0.05 * milk` multiplier. (For instance, at 50% milk, your CpS will be multiplied by 1.025.)

At 100% milk, Kitten workers. This adds an additional multiplier of `0.1 * milk`.
At 200% milk, Kitten engineers. This adds an additional multiplier of `0.2 * milk`.
Note: sometimes, for whatever reason, getting a new achievement while owning at least one Kitten upgrade will not change your CpS. To force the game to recalculate your CpS, go to your address bar and type in `javascript:Game.CalculateGains()` or `javascript:Game.recalculateGains=1`.
