Rake and equity

[TimmY222]

If you play cash games online. A part of your winnings will be raked from the Poker site. So if we say that the Rake is 5%, that will be 5% of all your earnings.
so if you win a 200bb pot at 25nl, it is in reality a $50 pot. but you only win a $47.50 pot. becouse of the rake.

your on a draw and got an estimated 55% equity in the pot.
if you choose to go all in on that draw everytime your in that spot, and your opponent will call you everytime. that play will be neutral EV? Couse you "will" win the pot 55 times out of a 100, but 5 of the 55 pots you won will be lost in rake.
Correct me if im wrong here.

This is VERY general and of course you have fold equity ++..
But if we look away from that..
villain will call and our equity in the pot is correct.

Well, the money already in the pot is typically visible net of rake. Online, the picture in the middle has the rake taken out. Live, the dealer has already placed the chips on the rake slot or wherever they go.

But you appear to be asking about rake on the fresh money coming into the pot. Depending on the rake structure, this could be significant at low stakes if the all-in is a huge overbet to the pot. If the rake is 5% to $3 (pretty standard online IIRC), $1 gross in the pot would show up as 95c. Now a PSB of $1 is going to lay you 1.85:1 ($1.85 to $1, because a nickel of your call is going to be collected in rake) instead of 2:1, which might swing a few decisions. (It will look like a slight overbet compared to the net amount in the pot, 95c, but Full Tilt's "bet pot" buttons use the gross and others probably do.)

But a huge overbet push of $20 is charging you $20 to win $18.95, or offering about 19:20. You'd think you're getting 21:20, so you might accept a dead-even proposition that really pays less than even money.

So yes, the impact of the rake matters as the size of the overbet increases.

However, something else happens at stakes big enough for the rake to get routinely capped. If rake is 10% to $4 (a common casino rake), then a $5 bet into a pot of $5 offers only 9:5 to call, not 2:1. But a $36 bet into a pot of $40 gross ($36 net and visible) offers 2:1 exactly, because the max. rake is already taken out.

In general, except for extremely marginal decisions regarding huge overbets at relatively small stakes, I don't think it would matter much.

Ty. answers my poorly put question very well

AKQJ10 appeared to nail this question.

I have an example which you may see happen in a live 1-2 game, where this would definitely be a factor.

4 players to a flop for $2, one is extremely shortstacked with $16 left. He pushes allin and everyone folds to you. the pot odds are 24:16 , but factoring a $4 rake and a costumary $1 tip, your adjusted pot odds are 19:16.

If you figure yourself to be about a 1.5:1 dog, it would be okay to call in the first case, but it would be wrong in the second case.

I'm not sure that this would occur online very often, but the rake is something to consider when you have a very marginal decision.
