8 rank

Average is 4

First class 8

Then better than average 

Impressive 

Outstanding 

From average to first-class

4 ranks is 9*4 or 36 chocotrains

At 1m a chocotrain that's 36m

Another 9 to cap first class

45,000,000 that's one stat

You need two stats and a third around average 

That's 45+45 and another 15 or so

90+15. 105,000,000 to max your choco using trains

A maxed choco is desired to be ok the same level of a ag relic ag mythic an escu an ag empy

Expecting around 150,000,000 to go from egg to maxed

And you need around 6 maxed Chocos to do everything 

Racing

Diggingx3 for different dig builds

Looking at around 600,000,000 gil to fully finish raising chocobos

And since we make exactly that much

This works out for everyone that plays FFXIV

From day one choco raising to completely finish breeders

The next 1,000,000,000 investment
