You have to actually put money in the pot. This can be playing the hand to showdown, limping in and folding to a raise, or even folding in the small or big blind.

Once you commit any money to the pot you get full credit for the pot regardless of the size. If you're at a $25 no-limit table and two people each go all-in for $50 and you fold the small blind you still get full credit for the pot.
