equity
One's mathematical expected value from the current deal, calculated by multiplying the amount of money in the pot by one's probability of winning. For example, if the pot currently contains $100, and you estimate that you have a one in four chance of winning it, then your equity in the pot is $25. If a split is possible, the equity also includes the probability of winning a split times the size of that split; for example, if the pot has $100, and you have a 1/4 chance of winning and a 1/5 chance of taking a $50 split, your equity is $25 + $10 = $35.

fold equity
The extra value gained by forcing your opponents to fold, rather than seeing the showdown. See also equity.

PokerStove is usually how people calculate equity as a fraction, in which case the PokerStove FAQ is good.

Q1. What does PokerStove calculate?

[ QUOTE ]
The values generated are all-in equity values. This is not the chance that a hand will win the pot. Rather it is the fraction of the pot that a hand will win on average over many repeated trials, including split pots. The equity for a hand is calculated by dividing the number of "pots" that the hand won by the number outcomes considered. Because two players can split a pot, a player can win fractional pots. Thus, it is possible for a hand to have non-zero equity despite the fact that it cannot win.


equity (%) win (%) / tie (%)

Hand 1: 50.3340 % [ 49.39 00.95 ] { 2s2h }
Hand 2: 49.6660 % [ 48.72 00.95 ] { random }

In the above example the pair of twos has 50.334% equity. That equity is made up of 49.39% win equity, and .95% tie equity. The tie equity is not the percentage of time that a hand will tie, rather it is the equity attributed to ties. Tie equity is reported instead of % tie because the amount of equity that a tie generates depends on how many players shared the pot. If two players share a pot, half the equity for that pot will given to each player. If three players share a pot, one third of the equity for that pot will be allocated.

I don't know of any posts that talk about these specifically.

I've never heard of "call equity."
