Bet sizing calculator
Apply flat staking: pin a fixed percentage of your bankroll to every bet, so a losing streak takes a predictable number of bets to deplete it rather than one oversized wager wiping you out.
Staking plan
Flat staking typically uses 1-5% of bankroll per bet. Above 5% is aggressive sizing.

Losing streak survivability
Flat staking keeps every bet the same fraction of your original bankroll, so no single loss can wipe you out - it takes a full losing streak of this length.
Educational estimate, not a betting recommendation. This assumes flat staking at a constant percentage of your starting bankroll and does not account for variance in a real losing streak, changing odds, or operator stake limits.
