I made this little infographic a while ago, after an idea on steemit.chat ...
Originally, I was going to write a proper piece about STEEM Vests and how they work and how to calculate things with it, but by the time I got to it, there were already enough guides on Steemit.
This is a joke !
Of course, this is not really how STEEM Vests work. *
* In reality, they are much fluffier.
To find more about Vests, try the Steem - Wiki for example:
