RTP (Return to Player) is the measure of how much money a casino game returns to players in the long run.
The higher this percentage, the more the casino pays out to the players. For example, if a slot has an RTP of 98%, it means that for every $100 wagered, it returns $98 to players and keeps $2 as profit.
Remember: RTP = how much the casino returns to its clients. House edge = how much casino keeps (example: 98% RTP = 2% house edge).
Every game at online or offline casinos has a Return to Player (RTP) rate, whether it’s roulette, lottery, blackjack, craps, video poker or slots.
How to Calculate RTP
RTP is easy to calculate with this formula:
- RTP = (Amount returned) / (Amount wagered) x 100%
For example, if a slot machine pays out $4,900 to players after they have wagered $5,000, the RTP is:
- RTP = ($4,900 / $5,000) x 100% = 98%
Note: A good RTP is considered to be 97%+.
Why RTP Matters
RTP is not a guarantee. It’s a long-term average that is based on thousands of spins. In the short term, anything can happen. You can hit a big win or lose everything regardless of the RTP.
However, it’s still a key factor because it tells you your expected return from playing. That’s why you should always check it before you play.

How and Where to Find Out the RTP
You can find the RTP of any casino game, whether it’s online roulette, craps, blackjack or slots. Just look for the information here:
- Scan the casino site: Many online casinos show the RTP of their games on their website or in the game itself. Just look for the info icon.
- Go to the game provider’s site: No RTP on the casino site? Search for it on the game provider’s site (for a NetEnt slot, go to their site and enter the game name to see its RTP).
