What You'll Need To Build Your Hold Em Calculator
If you simply want a Texas Hold Em calculator on your home computer or laptop the only things you'll need would be...
1. A copy of Micosoft Excel or Open Office Spreadsheets
2. An understanding of math equations and imputing information into Excel
3. This How To guide and about five minutes of time
Texas Hold Em Math Equations
We'll begin with the # of outs for the turn or the river math equation. This one is very straight forward. Take the number of cards in the deck (52) and subtract the total number of known cards from that number. In the case of the turn you would subtract 5 from 52 as you know 5 total cards, your 2 hole cards and the flop. For the river it would be subtracting 6 from 52. So we've determined that the number of cards remaining in the deck for the turn is 47 and for the river it's 46.
Leave 1 cell available in Excel. This will be the cell where you input your number of outs. Label cell B1 # of outs so you remember that cell A1 is your input cell. Now in C1 type in =(A1/47)*100. The reason you want to multiply by 100 is because you want to have a nice rounded number that is easy to read. Now whenever you put your outs into cell A1 cell C1 will spit out your percentage for you.
To do the river simply move down to cell C2 and input =(A1/46)*100. You now have a working hold em calculator that will tell you the number of outs for either the turn or the river.
The formula for both the turn and river is a little bit trickier. In excel your formula is going to look like this =(1-((47-A1)/47)*((46-A1)/46))*100.
Now to go over why everything is where it is. We begin with the #1. Without 1 there, you would be told the percentage you will not win the hand, as opposed to actually winning it. 47 minus A1/47 is for your turn percentages. A1 is still the cell you are inputting in the number of outs you have available to win the hand. 46-A1/46 is for the river. Please copy and paste the formula as it appears above exactly as it is written as the parenthesis are in the correct places to ensure that each part of the equation is done in proper order. You can place the above equation into cell C3.
Lets cover odds against very quickly. Odds against is simply the number of cards in the deck that hurt you divided by the number of cards that actually help you. For the turn your equation would be =(47-A1)/A1 and for the river your equation would be =(46-A1)/A1. These equations should be placed in cells E1 and E2.

Creating pot odd hold em calculators
If you want to know whether or not you're making a good play based on pot odds compared to the odds against you winning (from the last equation above) simply use this simple math equation the money in the pot divided by the cost to call. In this case you would need 2 blank spots on your Excel page. Let's use cells A5 and C5 for this. B5 is where you will write "cost to call" so you remember what A5 is for and for D5 you will type in "money in pot." For cell E5 use the equation =C5/A5.
To know whether or not you are making the correct call here, look at the odds against in the equation for odds against your hand hitting. If the pot odds against is less than the odds against your hand hitting, you are making a wise decision.
If you would like to know if you're making the correct call based off percentages than this equation might be more up your alley. Again we are going to be making use of cells A5 and C5. For percentages you take the cost to call and divide it by the money in the pot and the cost to call. The equation would look like this =(A5/(C5+A5))*100. Place the equation into cell E6. Again we're going with the multiplying by 100 to avoid messy decimals. Your percent to win must be greater than the percentage you are investing into the pot to make your call worth it pot odds wise.
Remember, Texas Hold Em is a game of investments. You are investing in good hands and wise decisions, just like with the stock market. With your very own calculator by your side you will be able to make the proper plays to make you a lifetime winning player. As with the stock market there will be swings. Your aim is to be an overall good player, the swings come and go. By making the wise decisions you are on the road to victory. If you play for real money please play responsibly.
If this seems too time consuming you could always just find someone willing to give you a pre-made hold em calculator for free, and just use that one.
