Bankroll Calculator
Flat percentage staking is the simplest bankroll management method: risk a fixed share of your current bankroll on every bet, so stakes shrink automatically during a downswing.
How it works
Recalculating the stake from your current (not starting) bankroll means a losing streak reduces future stakes automatically - you can never lose your entire bankroll on a finite string of losses under pure percentage staking.
Worked example: A $1,000 bankroll staking 2% per bet risks $20 on the first bet; after a loss, the next stake is 2% of $980 = $19.60.
FAQ
What percentage should I use?
Most disciplined bettors stay in the 1-5% range; the Kelly Criterion Calculator gives a theoretically-grounded number if you have an edge estimate.
Fixed stake or percentage stake - which is better?
Percentage staking scales down risk automatically in a downswing; fixed staking is simpler to track. The Bankroll Simulator lets you compare both directly.
