There are several different pieces of information that you must have to figure out the payout percentage. Unfortunately, most U.S. casinos do not disclose this information very readily.

How to Find the Percentage Payout on a Slot Machine

Finding out the percentage payout on a slot machine, especially in the United States, is not an easy task to accomplish. This is because the information is not displayed for players to readily see in most casinos.

Do Your Research

Like many things in life, doing a little research can often give you much of the information you may need to make informed decisions. Figuring out the payout percentage for slot machines you play is no different from that.

Casinos are required to report on many of their operations and earnings over time for the various games and offerings they provide. This information, if you can find it, will provide you with valuable information about the average payouts of casinos you may frequent.

Depending on the casino, they may produce the report either once a month or even annually since their only requirement is to ensure that the data is reported accurately. While most casinos release this information monthly, it may not be as easy to find as you may think.

In using this information to discover the payout percentage, you may need to drill down in the reports to the specific type of slot machine that is offered. This is because the payout percentage will vary depending on the amount of money you have to initially invest.

Check the Slot Information Screen

In other countries outside the United States, the information for payout percentages and probabilities of winning are often posted on the screen of the slot machine. This is because those casino owners believe that transparency is more attractive to customers and bring them back over time.

If you are playing the slot machines in the United States, however, you will not have the luxury of seeing these numbers so readily. This is because most casino owners in the states do not post these totals on the slot machine.

For those casinos that do post the amounts, you will need to keep in mind that the percentages posted are typically averages. This means that you will need to calculate the exact payout percentages based on those numbers.

Although you are not likely to be able to use this method to figure out the payout percentages on slot machines in the United States, if you are gambling in another country, you may be able to do this. However, if you are stuck playing the slots in the U.S. there are other methods you can use to find out the payout percentages.

Look Up the Percentage Online

Another possible way to find out the payout percentage on a slot machine is to look on the manufacturer's website. This is because many will post the average RTP, or return to player, numbers for their particular machines.

The reason they post this information is to attract casino owners to purchase their slot machines for their business. Providing this data allows casinos to purchase a wide variety of machines with payout percentages across the board.

If you are interested in finding out the payout percentages on slot machines you use in your favorite casino, all you need to do is find out the manufacturer and look up the information. In most cases, it is easy to find in the description of the slot machine.

It is important to note that while this is a great way to find out the payout percentages, you should remember that these numbers are reflective of the slot machines as they are at the warehouse. The casino owners may choose to alter the averages after they purchase the machine.

By altering their slot machines, they can either lower or raise the average payout percentage to fit their needs. The thing is, you will not know if a certain machine has been altered or if it stays in line with the manufacturer’s settings.


Overall, it is important to keep in mind that gambling of any kind is risky and could cause a gambling addiction. However, if you choose to play the slot machines at your favorite casino, then you may be interested in learning more about payout percentages to get more out of your money.

There are several ways to find out the percentages if you are willing to put in the work to do so. While some methods are better than others, you should use the one that you are more comfortable with overall.
