Bankroll & session calculator
See how long a bankroll should last at your stake, and a sensible bet size.
These are averages driven by the house edge; a real session swings with variance. A budget is money set aside for entertainment, not an investment. 18+ · play responsibly.
How to use it
Enter the bankroll you have set aside for entertainment, the amount you bet per spin, the RTP of your game, and roughly how many spins you play per hour (400 is a common pace on slots). The calculator returns your expected hourly cost, how long the bankroll should last on average, and a suggested bet sized at 1% of the bankroll.
Reading the results
The expected cost per hour is the house edge multiplied by how much you wager each hour, it is what the game costs you on average, not a fixed fee. Estimated playtime divides your bankroll by that hourly cost. The suggested bet keeps a single spin small relative to the whole bankroll so variance can't wipe you out in a few rounds.

Play within the budget
A bankroll calculator makes play more predictable, but it does not remove risk. Set deposit limits, use reality checks, and never chase losses. If gambling stops feeling like entertainment, our responsible gambling page lists free, confidential support.
