Bankroll planner

Fact checked |
Choosing how much to bet is the most important decision you make during a session. It is more important than picking a game or a promotion. This planner uses your bankroll, how long you plan to play, and your preference for risk. It then suggests a bet size that helps you play for as long as you planned.
Variance preference

Suggested bet size

$0.16$0.66

Recommended bet range for a 2-hour session on medium-variance games with your bankroll. Choose the lower end if you want longer sessions and milder swings; the upper end if you prefer fewer, larger swings.

Session risk at midpoint bet ($0.41)

low

Expected session loss at the midpoint bet: $16.47. A typical bad-but-not-extreme outcome (2σ downswing) would lose about $224.80 - that's 45% of your bankroll. Anything above 90% means a normal-variance run can wipe out the session.

Expected spins

1,000

~500 spins per hour

House edge

4.00%

Per-spin take by operator

Volatility class

medium

~8x bet stddev per spin

Variance modeling is approximate - individual slot titles vary within their class. The math assumes consistent bet sizing across the session; doubling-down or stop-loss behavior changes the distribution. Past sessions are no guide to future ones; the law of large numbers needs much longer than one session to express itself.

How the suggestion is calculated

We recommend a bet range based on two limits, and we use whichever is stricter:

  1. Expected-loss budget. Your expected loss for the session (bet amount x number of spins x house edge) should remain under about 25% of your bankroll. This gives you enough buffer for typical fluctuations without losing your bankroll solely based on statistics.
  2. Variance tolerance. Your bankroll should be large enough to cover a significant downward swing (a three-sigma event, which happens in about 1 in 800 sessions). This is the minimum amount you need to survive a bad streak.

High-variance games, such as Megaways or titles focused on maximum wins, usually require smaller bets. This is because their volatility is much higher. Even a standard run can have long periods without a win before a big payout happens. Low-variance games allow for larger bets because the swings in your balance are generally smaller.

Why bet sizing matters more than game choice

If you have a $500 bankroll and bet $5 per spin, you will run out of money in about 100 spins, which is roughly 12 minutes of play. If you bet $0.50 per spin with the same $500 bankroll, you can play for 1,000 spins, or about two hours. This gives you much more time to handle losing streaks. The game you choose changes your experience, but the bet size decides how long you can play.

The most common mistake people make is betting to win a large amount quickly, rather than betting to last for their planned session. Betting $5 with a $500 bankroll on a medium-volatility game is risky. One short bad streak could wipe out your balance. A bet between $0.50 and $1 is a safer, more realistic amount for a two-hour session.

What the planner does NOT tell you

  • Whether you'll win. This planner suggests a bet range that helps you handle typical swings during your planned session. It cannot predict the outcome of your games. You could win or lose with any bet range in a single session.
  • When to stop. Deciding when to stop playing is about discipline, not bet sizing. Bet sizing helps you stay in the game for longer, but your own discipline helps you stop at the right time.
  • Whether you should be playing. If you are playing with money you cannot afford to lose, then no betting strategy will help you. In that case, the problem is the bankroll itself. Please check our responsible gambling page and self-exclusion guide if you feel this applies to you.
