Build Your Staking Plan

Your bankroll should be money you can afford to lose entirely — never rent, savings, or borrowed funds.

If your bankroll drops by the stop-loss amount, pause, review your bet history, and resize units from the new balance before continuing.

Why Bankroll Management Beats Handicapping

Most losing bettors do not lose because their picks are bad — they lose because their stakes are chaotic. A bettor hitting 55% at -110 (comfortably profitable) still goes broke if they stake 20% of bankroll per bet and hit a routine 5-loss streak. Flat unit sizing turns the same picks into steady growth.

The math is unforgiving: losing 50% of a bankroll requires a 100% gain to recover. Protecting the downside is not cowardice, it is compounding.

The Three Rules That Matter

Rule one: never bet more than 1-3% of bankroll on a single wager, no matter how certain it feels. Rule two: cap daily exposure at 3 units — bad days should be survivable, not devastating. Rule three: resize units monthly or after a 15% swing in either direction, so stakes always track your actual balance.
