How much profit do slot machines make?

Slot machines are one of the most popular forms of gambling in casinos around the world. Their flashy lights, exciting sounds, and potential for big payouts make them an attractive option for many casino gamblers. But behind the exhilarating facade, slot machines are big business for casinos. Just how much profit do slot machines make for the house? Let’s take a closer look.

Slot Machine Basics

Before diving into the profits, it’s helpful to understand some basics about how slot machines work. At their core, slot machines are electronic gaming devices that utilize random number generators (RNGs) to produce combinations of symbols on reels. When certain symbols line up in predetermined ways, players win prizes.

Each slot machine is programmed with a payback percentage – the amount of money it pays out in prizes over time compared to how much money it takes in. A machine with a payback percentage of 90%, for example, would be expected to pay out $90 for every $100 wagered on it.

The payback percentage does not mean you will win 90 cents for every dollar bet in the short term. Rather, it refers to the machine’s overall payout behavior over hundreds of thousands of spins. You could lose money over your first few spins but then hit a big jackpot, bringing your overall payback in line with the programmed percentage over time.

Casinos make their profit on the difference between the payback percentage and 100%. For example, if a slot machine has a 90% payback, the casino profits by keeping 10 cents from every dollar wagered.

Average Casino Slot Payback Percentages

So what are the typical payback percentages for casino slot machines? This can vary based on the jurisdiction, casino policies, competition in the area, and whether it’s a high or low limit machine.

Some general averages:

  • Las Vegas strip – Between 75% to 95%
  • Atlantic City – Around 90% to 95%
  • Native American casinos – 80% to 95%
  • Riverboat casinos – 90% to 95%
  • Downtown Vegas – 85% to 95%

As you can see, overall slot payback percentages are generally in the 80% to 95% range at most casinos.

Factors That Influence Slot Machine Payback Percentages

Several factors go into determining a slot machine’s payback percentage:

  • Location – Higher traffic areas like near table games or aisles often have lower payback percentages to take advantage of passing traffic. Machines tucked away in corners or back rooms tend to have higher percentages.
  • Popularity – More popular titles based on movies, TV, bands, etc. often have lower percentages because people play them regardless of the odds.
  • Jackpot size – Machines with progressive jackpots or other large top prizes tend to have lower base payback percentages to counterbalance the risk of huge payouts.
  • Bet size – In general, higher bet or limit machines will have higher payback percentages to appeal to high rollers.

In the end, the casino will aim to strike a balance between payback percentage and profit across its overall slot offerings.

Typical Profit Margins for Slot Machines

Now that we understand how payback percentages work, what do typical slot machine profit margins look like for casinos? Again, this can vary significantly based on specific circumstances, but some general ballpark figures are:

Payback % House Advantage/Profit
92% 8%
91% 9%
90% 10%
89% 11%
88% 12%
87% 13%
86% 14%
85% 15%

As shown above, a slot machine with a 90% payback keeps 10% of money wagered as profit. One with 85% payback keeps 15% as profit. This payback-to-profit ratio remains relatively constant across the industry.

Factors Influencing Overall Slot Profitability

Simply having a good payback-to-profit ratio doesn’t guarantee slots will be highly profitable for the casino. Maximizing slot profits also relies on getting players to wager as much money as possible. Some key factors for driving more slot play and profits are:

  • Location – Placing slot machines in high traffic spots entices more players to stop and try their luck.
  • Access – Having slots easily accessible throughout the casino and not just in a corner encourages more play.
  • Comfort – Comfy chairs and conveniences like drink holders keep players seated longer.
  • Entertainment – Exciting sound and visual features attract more players and extends their session.
  • Denominations – Offering a variety of low to high denomination machines accommodates every budget.
  • Rewards – Slot clubs and rewards programs encourage brand loyalty.

By optimizing these factors that promote greater slot play, casinos can significantly boost their overall profits beyond just having machines with good payback-to-profit ratios.

Slot Machine Profitability Compared to Other Games

Slot machines are generally among the most profitable casino games for the house. Their profit margins tend to be higher than table games like blackjack, craps, baccarat, and roulette. Some key comparisons:

Game Typical House Edge/Profit Margin
Slots 10% or higher
Blackjack 0.5% to 2%
Craps 1.4% on basic bets
Baccarat 1.1% to 1.3%
Roulette 2.7% (European) to 5.26% (American)

As you can see, slots have a significantly higher house edge, usually at least 10%, while other popular games are under 3% on average. This makes slots extremely profitable for casinos.

Revenue Statistics on Slot Profitability

Looking at actual gaming revenue statistics further demonstrates the profitability of slots for casinos:

  • In Nevada, slots generated over $7 billion in gaming revenue in 2019 – 63% of the state’s total gaming revenue.
  • Pennsylvania slots revenue reached $2.5 billion in 2019, comprising over 60% of gaming revenue.
  • New Jersey’s slots revenue was over $2.7 billion in 2019, about 61% of total gaming revenue.
  • In 2019, Las Vegas Strip slots revenue accounted for 51% of total gaming revenue on the Strip.

The significant portion of revenue – usually 50% or more – that slots generate for casinos clearly shows their profitability. This percentage is disproportionate compared to the lower number of slot machines on many casino floors versus table games. Slot machines simply make that much more money pound for pound than other games.

Profitability of Specific Slot Machines

Looking at individual slot machines, the amount of profit they generate for casinos can vary greatly depending on how hot or cold they are. Some examples of profitability on specific slots at casinos:

  • A bank of Wheel of Fortune slots at an Atlantic City casino generated over $160,000 in profits in just one month.
  • A single Money Madness slot machine at a Las Vegas casino had profits of over $100,000 in a four-month span.
  • A Lion’s Share slot in Vegas was notorious for only paying out around $200,000 despite taking in over $10 million over its 20 year lifespan.

These examples illustrate how certain machines can rake in tens or hundreds of thousands in profits in short periods. Even slots notorious for their stinginess still generate substantial profits over the long-term.

Progressive Jackpots – Low Payback, Huge Profit Potential

One slot category warrants special mention – progressive jackpot slots. These machines offer life-changing multi-million dollar jackpots, but have very low base payback percentages:

  • Megabucks – Base payback around 75% without jackpot factored in
  • Wheel of Fortune – Base payback around 75% also
  • Various progressives – Base payback averaging 50% to 70%

So while the grand jackpot captures players’ imaginations, the casinos are keeping 25% to 50% of all money played on these machines. The huge jackpots mask profits that can often run upwards of 50 cents from every dollar wagered.

Maximizing Slot Profits Through Player Tracking

Modern slot machines are tied into player loyalty programs that allow casinos to track play and target their most loyal patrons. Some ways casinos leverage this data to maximize slot profits:

  • Offering free slot play and other incentives to encourage players to return
  • Enticing players to try higher denomination or max bet machines
  • Direct mail offers to inactive slot club members to reengage them
  • Personal interaction to build loyalty among proven slot spenders
  • Analyzing play data to optimize slot floor layout and performance

So player tracking systems give casinos reams of actionable data to strategically target slot offers and stay ahead of the competition.

Slot Performance Optimization

Casinos continuously analyze slot performance using various metrics to optimize profitability. Some key optimization techniques include:

  • Win per unit – Profit generated on average per machine
  • Hold percentage – Percentage of money played kept by casino
  • Game conversion – Percentage of floor traffic that plays a slot
  • Time on device – How long players engage before leaving
  • Age of game – When machines were installed and need replacement

By tracking such metrics and fine-tuning their slot offerings, casinos can achieve and maintain strong slot profit margins.

Non-Gaming Revenue from Slots

While the direct gaming profit is the primary driver, slot machines also generate significant non-gaming revenue. This includes:

  • Food & beverage – Players take breaks to eat and drink while gaming
  • Retail shopping – Players make impulse purchases in casino shops
  • Entertainment – Players attend concerts, nightclubs, etc. around gaming
  • Hotel rooms – Out-of-town players book overnight hotel stays

These supplementary revenue streams add substantially to the bottom line for casinos. Profits from slots go far beyond just the gaming revenue alone.

Slot Revenue Trends

Slot machine revenues have shown stellar growth over the past two decades, both in traditional gambling hubs and newer gaming markets. Some revenue trends since 2000:

  • Las Vegas Strip slots revenue has increased over 170% from $866 million to $2.35 billion.
  • Atlantic City slots revenue is up over 55% from $1.7 billion to $2.7 billion.
  • Pennsylvania slots revenue has surged from zero to $2.5 billion as the state legalized gaming.
  • Detroit, Michigan slots revenue has increased over 240% from $838 million to $1.41 billion.

These figures demonstrate that slot profitability has risen substantially with their spreading legalization across more jurisdictions. This has translated into tremendous revenues for casinos.

Slot Machine Revenue Outlook

Looking ahead, all indicators point to slot revenues continuing to increase as more states roll out legal gaming. Growth factors include:

  • New casino openings in expanding markets like New York and Virginia
  • Continued migration toward nationwide online/mobile slot play
  • Millennial preference for slots over tables
  • Higher limits and more comfortable amenities catering to older players
  • Legalization momentum as more states add gaming to revenue mix

Given these dynamics, global annual slot revenues could hit over $100 billion by 2030 according to some projections – nearly double current levels.


Slot machines provide an extremely profitable source of gaming and non-gaming revenue for casinos around the world. Their ability to generate significant profits – typically 10% or more of amounts wagered – while also enticing continuous play through exciting features has made slots the go-to gambling option for millions.

With slot revenues already comprising 50% or more of total gaming revenue in most casino markets, their proportion is likely to rise even further as gaming expands into new jurisdictions and online channels in the coming decade. For casinos, adapting to optimize slot placement, amenities, loyalty programs, and data analysis will remain key to tapping into these highly profitable machines for years to come.
