RTP is a long-run expected return under a game’s stated rules. House edge is its complementary expected share, commonly 100% minus RTP. Volatility describes variation in outcomes. None of these tells you what one session will return.
RTP is not a personal refund
A game described with a 96% RTP does not promise that a player who deposits $100 will receive $96 back. RTP relates to total stakes across a sufficiently large number of plays under a mathematical model. Actual session results can differ widely, including losing the full amount set aside.
The house-edge calculation
In a simple game model, 100% minus 96% RTP gives a 4% house edge. With an illustrative $1,000 of total stakes, the mathematical expected loss is $40. This is an expectation across repeated outcomes, not a bill, a maximum loss or a prediction. It assumes the advertised model applies to the exact game and bets.
Why turnover matters
A player can stake more than an initial deposit by repeatedly wagering remaining funds and winnings. This is why expected loss is calculated from total stakes, not simply the first amount deposited. A calculator that multiplies house edge by deposit size without knowing turnover cannot describe the full session exposure.
Volatility answers another question
Two games with the same RTP can distribute returns differently. One might pay smaller amounts more frequently, while another concentrates a larger share of its return in rare events. Equal RTP does not make their short-session experiences equivalent. No volatility label provides a guaranteed route to a profit.
Check the actual game version
Read the game information available at the point of play. A studio may offer variants or configurable return settings, and special bets can have different rules. Do not copy an RTP from a review of a similarly named game and assume it applies. Promotional rewards are also separate from the underlying game mathematics.
Use the model carefully
The calculator below shows the house edge and theoretical expected loss for a user-entered RTP and total stake. It does not simulate volatility, measure the actual casino or include bonuses, exchange fees or crypto price movements. Your actual loss can be the entire amount you risk. Use a budget you can afford to lose and stop at your predetermined limit.
RTP & expected loss
A simple mathematical expectation, not a session forecast.
House edge 4% × total stakes 1,000
Actual results can vary widely; you can lose the full amount at risk. This model excludes volatility, bonuses, fees and crypto price movements. It assumes the entered RTP applies to the exact bets.
