Bankroll Survival Calculator
Every casino game has a house edge that quietly drains your bankroll over time. This calculator shows you exactly how much a session costs, how long your budget will last, and how switching games can save you real money. Adjust the inputs below and watch the numbers update in real time.
How the calculator works
The calculator uses each game's known house edge to compute your expected loss over a given number of rounds. The house edge is the percentage of every bet the casino keeps on average — it is built into the game's maths and cannot be avoided through strategy or timing.
Expected loss = bet size × number of rounds × house edge. This is the mathematical average — your actual result will vary due to variance, but over many sessions, your results will converge to this number.
Ruin probability estimates your chance of losing your entire session budget before completing all rounds. It accounts for the cumulative effect of bet-by-bet variance — even with a small house edge, large bets relative to your budget increase the chance of going bust.
Cost per hour depends on game speed. Live blackjack deals about 30 hands per hour, while crash games can run 100+ rounds per hour. Faster games cost more per hour even if the per-bet house edge is similar.
House edge comparison
| Game | House Edge | Loss per $1,000 Wagered | Speed |
|---|---|---|---|
| Live Blackjack | 0.5% | $5 | ~30 rounds/hr |
| BC.Game Crash | 1.0% | $10 | ~100 rounds/hr |
| Roulette | 2.7% | $27 | ~45 rounds/hr |
| Aviator | 3.0% | $30 | ~100 rounds/hr |
| Roobet Crash | 3.5% | $35 | ~100 rounds/hr |
| Mission Uncrossable | 4.0% | $40 | ~100 rounds/hr |
| Plinko | 4.0% | $40 | ~80 rounds/hr |
| Slots (average) | 4.0% | $40 | ~60 rounds/hr |
Key takeaways
- Game choice is the biggest lever you have. Switching from slots (4% edge) to live blackjack (0.5% edge) cuts your expected cost by 8x for the same amount wagered.
- Bet size relative to budget determines ruin risk. Betting 1% of your budget per round is conservative. Betting 5%+ is aggressive and significantly increases bust probability.
- Faster games cost more per hour. Crash games at 100 rounds/hour cost 3x more per hour than blackjack at 30 hands/hour, even if the per-bet edge were identical.
- Set a session budget and stop. The house edge is unavoidable. The only bankroll management decision that matters is deciding in advance what you can afford to lose.
