What is the Payout Percentage of a Slot Machine?

The payout percentage of a slot machine can range from as low as 75% up to around 99%. It is important to have an idea of the payout percentage of the slot you choose to play to know your expectations.

The higher the payout percentage, the better is for the players. So, it is beneficial for players to go for slot machines that have a higher value of payout percentage.

The payout percentage of a slot and house edge are related. They together add up to 100%. The higher the house edge of a slot, the lower will be the payout percentage.

If the house edge of the slot game is 5%, then the payout percentage of that slot is 95%.

How to Determine the Payout Percentage of a Slot?

Here are the methods that might work to find out the payout percentage of a slot game.

a. Read the information screen of the game

Slot machines are not usually labeled with their payout percentage. However, if you find a slot with such labels, then all you need to do is read the information. Then, you can simply determine if the slot is worth playing or not.

b. Look up the payout percentage of the slot

This method mostly works for online slots real money. Some slot game providers post a specific payout percentage of their slots.

However, you will not know whether the slot game has been set in its default as set by the manufacturer or not. The problem with this method is whether you can trust the posted number or not.

If you look up the posted RTP of a slot, you will get a decent idea of how much the slot pays out although you might be off by a few points.

c. Research average payouts for determining the payout percentage

The gambling boards and regulators have to report the data of slot machines on a general basis. The data generally have to be reported monthly or in some cases annually.

The slot players can get a better idea of the payout percentage of a slot by utilizing the information available in those reports.

d. Track your play for determining the payout percentage

This method doesn’t work since you can’t track your play over a long period of time. However, you can get some sense of the payout of the slot machine over the short duration of your play.

For this, you have to know your number of spins per hour. You can note your number of spins for 5 minutes and then multiply that number by 12 to get your number of spins per hour.

Bet the same amount in each spin to have a unit bet size. Take note of how much you have before playing and how much you have at the end of your 1-hour game session.

For example; you have your bankroll of ₹10,000 and you are making 200 spins an hour at ₹10 per spin. That means you bet ₹2000 an hour. After an hour of your gameplay, you are down to ₹9,500.

That’s the loss of ₹500 across 200 spins i.e. the loss of ₹2.5 per spin. ₹2.5 is 25% of ₹10, which means the slot paid back 75% for the game session of an hour.

Why is the payout percentage calculated in this way not effective? It‘s because of the variance.

The payout percentage is based on a huge number of spins and not just 1-hour session. Your one-hour session can produce results that vary much from other players’ sessions.


We hope that this article helps you to get a better idea of the payout percentage of a slot and how it can be determined.

If you want to maximize your chances of winnings, then always go for slot machines with a higher value of payout percentage.

Slot games are luck-based games and always take them for what they are. If you are lucky, you can win big on slot games. Always set aside your bankroll for gambling.
