RTP vs House Edge: What’s the Difference?

RTP and house edge describe the same long-term casino mathematics from opposite perspectives.

RTP, or Return to Player, tells you the theoretical percentage of wagers returned to players over the long term.

House edge tells you the theoretical percentage the casino expects to retain over the long term.

In simplified terms:

RTP + House Edge = 100%

If you want the concepts individually first, read our guides to RTP and house edge.

RTP vs House Edge at a Glance

What Is RTP?

RTP stands for Return to Player.

It is usually shown as a percentage.

For example:

96% RTP

means that across a very large amount of wagering, the game is theoretically designed to return approximately 96% of total wagers to players.

It does not mean you will personally receive exactly $96 back from every $100 wagered.

What Is House Edge?

House edge is the casino's theoretical mathematical advantage.

For example:

4% house edge

means that across a very large amount of wagering, the casino theoretically expects to retain approximately 4% of the total amount wagered.

How Are RTP and House Edge Connected?

The relationship is simple:

House Edge = 100% − RTP

and:

RTP = 100% − House Edge

Example: 96% RTP

If a game has:

96% RTP

then its corresponding theoretical house edge is:

100% − 96% = 4%

Across $10,000 in total wagering, the theoretical long-term figures would be:

• Approximately $9,600 returned to players

• Approximately $400 retained through house edge

These are statistical expectations across large wagering volumes, not guaranteed outcomes.

Does 96% RTP Mean You Lose 4% Every Session?

No.

RTP and house edge are long-term mathematical concepts.

During one session, you could:

• Win more than you wagered

• Lose much more than 4%

• Finish close to even

Short-term results can vary significantly.

Why Is RTP Used More Often for Slots?

Slots are commonly described using RTP because it gives players a simple way to understand theoretical long-term return.

For example, a slot might display:

RTP: 96.20%

House edge can then be derived from that figure.

Why Is House Edge Used More Often for Table Games?

Traditional casino games are often discussed in terms of house edge.

Examples include:

• Blackjack

• Roulette

• Baccarat

This is often because different wagers or player decisions can have different mathematical advantages.

RTP and House Edge in Slots

If a slot has 96% RTP:

House Edge = 4%

If another slot has 97% RTP:

House Edge = 3%

From a purely mathematical long-term perspective, the 97% RTP game has a smaller casino advantage.

However, this does not tell you how volatile either slot is.

RTP and House Edge in Blackjack

Blackjack is more complicated because player decisions affect expected return.

A favorable game played with accurate basic strategy may have a relatively low house edge.

Poor decisions can increase the effective house edge.

This means the implied RTP can depend partly on how the game is played.

See our blackjack odds and house edge guide.

RTP and House Edge in Roulette

Standard European roulette provides a clear example.

Most common bets have a house edge of approximately:

2.70%

The corresponding theoretical RTP is approximately:

97.30%

Standard American roulette has a house edge of approximately 5.26% on most common wagers, corresponding to an RTP of approximately 94.74%.

Read our European vs American roulette comparison.

RTP and House Edge in Baccarat

Baccarat shows why one game does not always have one universal RTP or house edge.

The Player, Banker and Tie wagers have different probabilities and payouts.

That means each wager has its own house edge and corresponding theoretical return.

You can learn more in our baccarat guide.

Does Higher RTP Mean Lower House Edge?

Yes.

Because the two values are mathematical opposites, a higher RTP means a lower house edge.

For example:

Does Higher RTP Mean You Will Win More Often?

Not necessarily.

RTP does not tell you win frequency.

A game can have a relatively high RTP but return much of that value through rare larger wins.

Another game with the same RTP might produce smaller wins more frequently.

This is where volatility becomes important.

RTP vs Volatility

RTP describes long-term theoretical return.

Volatility describes how that return is distributed.

Two games can both have 96% RTP while feeling completely different.

One could have:

• Frequent smaller payouts

• Lower short-term swings

while another could have:

• Less frequent wins

• Larger potential payouts

• Higher short-term swings

Read our RTP vs volatility guide for the full comparison.

House Edge vs Win Probability

House edge is also not the same as your chance of winning an individual bet.

For example, red in European roulette wins on 18 of 37 pockets.

That gives a relatively high probability of winning one spin, but the bet still has a house edge because zero creates an additional losing outcome.

Can a Game Have 100% RTP?

Mathematically, a game with exactly 100% RTP would have a 0% theoretical house edge.

Most commercial casino games are designed with an RTP below 100%, creating a positive house edge.

Can a Game Have More Than 100% RTP?

A casino game with a sustainable base RTP above 100% would theoretically favor the player over the long term.

That is not the normal structure of standard commercial casino games.

Promotions or temporary rewards can affect a player's total value, but that is separate from the underlying RTP of the game itself.

Does Provably Fair Change RTP or House Edge?

No.

Provably fair concerns whether a result can be independently verified.

It does not automatically change the game's RTP or house edge.

A game can be provably fair while still having a 2%, 4% or other mathematical house edge.

See our provably fair vs RTP guide.

Does RNG Determine House Edge?

Not by itself.

RNG is used to generate outcomes within the game's probability model.

The house edge comes from the relationship between probabilities and payouts.

Does Bet Size Change RTP or House Edge?

Usually, increasing the size of the wager does not change the percentage RTP or house edge under the same game rules.

It does increase the amount of money exposed to that edge.

For example, a 4% house edge represents:

• $4 theoretical expected loss per $100 wagered

• $40 per $1,000 wagered

• $400 per $10,000 wagered

Again, these are theoretical long-term figures.

Why Total Wagering Matters

RTP and house edge apply to wagering volume rather than simply the amount deposited.

Imagine you deposit $100 and continue recycling winnings into new bets until you have wagered $2,000 in total.

On a 96% RTP game, the long-term mathematical expectation relates to that $2,000 of wagering, not only the original $100 deposit.

Which Number Should Players Look At?

Either RTP or house edge can describe the same long-term mathematical relationship.

If you are looking at slots, RTP is often the number displayed.

If you are comparing table games, house edge is often more common.

The important thing is understanding what the percentage actually means.

What RTP and House Edge Do Not Tell You

Neither number tells you:

• Whether you will win your next bet

• How volatile the game is

• How frequently payouts occur

• What the maximum win is

• How long a winning or losing streak may last

They are measures of long-term expected value.

Frequently Asked Questions

What is the difference between RTP and house edge?

RTP describes the theoretical percentage returned to players, while house edge describes the theoretical percentage advantage retained by the casino.

What is the house edge of a 96% RTP game?

Approximately 4%.

What is the RTP of a game with a 2% house edge?

Approximately 98%.

Does 96% RTP mean I get $96 back from $100?

No. It is a long-term statistical expectation across a large volume of wagers, not a guarantee for one session.

Is higher RTP better mathematically?

A higher RTP means a lower theoretical house edge under the same type of calculation.

Does lower house edge guarantee that I win?

No. It reduces the long-term mathematical disadvantage but does not remove short-term randomness.

Is RTP the same as win rate?

No. RTP describes the value returned over time, not how often individual bets win.

Two Ways of Describing the Same Mathematics

The easiest way to remember the relationship is:

RTP looks at the game from the player's side.

House edge looks at the same mathematics from the casino's side.

A 96% RTP game has approximately a 4% house edge. A 98% RTP game has approximately a 2% house edge.
