Most pot odds advice makes you do the division before you can decide. This page does the division once, for the bet sizes that come up most often, so you can read the number straight off the chart and compare it to your hand.
The arithmetic behind every row is the same one described in how to calculate pot odds; if the idea of a price is new to you, start with what pot odds mean. What changes is only the bet size.
The chart
Assume the pot is 100 units before your opponent bets. Their bet is the fraction shown; your call is that same amount. Required equity is the call divided by the pot after your call.
| Opponent bets | Pot before bet | You call | Pot after your call | Required equity |
|---|---|---|---|---|
| 1/3 pot | 100 | 33.33 | 166.67 | 20.00% |
| 1/2 pot | 100 | 50 | 200 | 25.00% |
| 2/3 pot | 100 | 66.67 | 233.33 | 28.57% |
| 3/4 pot | 100 | 75 | 250 | 30.00% |
| 1x pot | 100 | 100 | 300 | 33.33% |
| 1.5x pot | 100 | 150 | 400 | 37.50% |
| 2x pot | 100 | 200 | 500 | 40.00% |
How to read it
The percentage in the last column is the share of the pot you would own if you call and go on to win. It is the break-even point, not a target: calling with exactly that much equity returns your call on average, so anything below it loses chips and anything above it gains.
Read the chart left to right and the pattern is clear. A small bet asks for a small share. A 1/3 pot bet needs only 20 percent. The same hand facing a full pot bet needs 33.33 percent, and facing a 2x pot overbet needs 40 percent. The bet size is the opponent setting your price.
Two rows are worth memorising because they come up constantly: a half pot bet needs 25 percent, and a full pot bet needs 33.33 percent. Those two numbers cover most of the decisions you will face.
Where the fractions come from
Each required equity is an exact fraction, not a rounded approximation:
| Bet size | Exact required equity | Decimal |
|---|---|---|
| 1/3 pot | 1/5 | 20.00% |
| 1/2 pot | 1/4 | 25.00% |
| 2/3 pot | 2/7 | 28.57% |
| 3/4 pot | 3/10 | 30.00% |
| 1x pot | 1/3 | 33.33% |
| 1.5x pot | 3/8 | 37.50% |
| 2x pot | 2/5 | 40.00% |
The fractions matter because the percentages are rounded to two decimals. If you are comparing a hand with 28.5 percent equity against a 2/3 pot bet, knowing the exact price is 2/7 helps you see that the call is marginally losing rather than marginally winning.
The mistake this chart prevents
The common error is comparing the bet to the pot in the wrong direction. If the pot is 100 and the bet is 50, the bet looks like “half the pot” and the instinct is to think you need about 50 percent. You do not. You need 25 percent, because the 50 you call becomes part of the pot you are trying to win.
Reading required equity off the bet size, rather than estimating it from the ratio of bet to pot, keeps this straight. The chart is just that relationship written out.
What the chart does not tell you
The number above is only the price. It says nothing about whether your hand has that much equity, and nothing about future betting.
For the equity side, you compare the required percentage against your outs and the cards still to come. For the future-betting side, the flat price on this chart ignores money you may win on later streets, which is why a call that looks slightly bad by pot odds alone can still be right when implied odds are large.
Use the chart to answer one question only: what does this call cost me in equity terms. Then decide whether your hand clears that bar.
