How to Use the House Edge Calculator
Enter a game's RTP percentage or input custom odds (true probability and payout) to calculate the house edge. The calculator shows the percentage the casino expects to keep from each bet over the long run. You can compare multiple games side by side to find the best value.
What the Results Mean
A lower house edge means the game is more favorable to the player. For every $100 wagered, the house edge tells you how much the casino expects to profit. A 2% house edge means $2 per $100 wagered on average. Use this information to choose games that give you the best odds and stretch your bankroll further.
Tips for Reducing the House Edge
Learn optimal strategy for skill-based games like blackjack and video poker — strategy mistakes increase the effective house edge beyond the theoretical minimum. Avoid side bets and novelty wagers, which almost always carry higher house edges than the main game. Choose European roulette over American roulette, and pass/don't pass over proposition bets in craps.
