How the planner works
- Budget per session = monthly budget / sessions.
- Units = budget per session / stake. More units means a longer session at the same stake.
- Wagered = stake × rounds. Average cost = wagered × house edge.
- Typical swing = stake × spread × √rounds, compared with the session budget.
Worked example (hypothetical)
A budget of 100 over 4 sessions gives 25 per session. At a stake of 2 that is 12.5 units. A session of 100 even-money roulette spins wagers 200 with an average cost of 200 × 0.027 = 5.40 at a 2.70% edge, and a typical swing of 2 × 1 × √100 = 20, which is 80% of the session budget. If the swing is close to or above the budget, a bad session can use all of it, and a smaller stake or fewer rounds is the usual adjustment.
Use it with limits
The planner does not replace limits. Set a budget you can afford to lose, set a time limit and use the tools described in setting a gambling budget and limits. See also bankroll and bet sizing in blackjack.
Frequently asked questions
What is a good number of units?
There is no single figure. Generally, more units per session leave more room to absorb variance. The right budget is one you can afford to lose.
Does the planner improve my odds?
No. It shows how a budget, a stake and the number of rounds relate. The house edge stays the same.
