Street-by-street bet sizing calculator
Set your flop, turn and river bets as a share of the pot and see how big the pot will be at showdown, how much you put in, and the effective stack it takes.

125Percentages are taken from the pot on that street, not from the starting one: a 75% bet on the turn is three quarters of an already swollen pot.

How this is worked out
The pot grows faster than it looks. Every next bet is measured against a pot that has already grown. That is why even a few moderate bets can send your whole stack into the middle by the river.
How the pot grows
Say there are 100 chips in the pot on the flop. You bet 50, your opponent calls 50 — and the turn starts with 200.
Bet half the pot again on the turn and that bet is already 100 chips. After a call the pot is 400, so half the pot on the river is 200.
So three bets of 50% pot are not three equal bets: they are 50, then 100, then 200 chips. That is exactly why a stack runs out sooner than you planned.
Why plan ahead
Your flop sizing decides what the pot will be on the turn and the river. So it pays to decide how much you want in the middle by showdown before you make the first bet.
If the goal is to get the stacks in by the river, pick sizings in advance so the pot grows steadily and the last bet does not turn out awkwardly large or small. If instead you want to leave your opponent room to continue with weaker hands and keep making mistakes, the bets can be smaller.
The «street by street» table shows how each sizing changes the fold frequency you need and the share of the range your opponent has to continue with.
