*Disclaimer: This calculator is only intended to help players understand how various gambling patterns can increase or decrease costs of play. Players should keep their own written log of time and money spent to determine if their own playing patterns are affordable. Calculations are based on game rules and house advantage for the Ontario Lottery and Gaming Corporation (OLG). The house advantage may vary by plus or minus 1% on any game. Results may vary in other jurisdictions.

Looking at the cost of play over time will help players get a practical view of the long term costs involved in gambling.

When someone gambles, it is not possible to know the cost of play in the short term (after just one or a few sessions of play) because the results can vary widely due to the randomness of the game. However, in the long run, the cost of play is more predictable and can be estimated using this calculator.

The calculator shows the average amount per hour, per month and per year that players will spend. This cost includes all wins and losses experienced by players.
