Bankroll management calculator
Ako táto kalkulačka funguje
The fundamental rule of bankroll management is never to risk so much on a single bet that a losing streak can wipe you out. The recommended unit stake is a fixed percentage of your total bankroll. Conservative bettors use 1-2%; aggressive bettors go as high as 5%.
The number of bets in bankroll equals total bankroll divided by unit stake. At 2% per bet with a 500-unit bankroll, you have 50 bets before the bankroll is exhausted. This buffer is essential for surviving the inevitable losing runs that all bettors face regardless of long-run edge.
Expected value per bet = (win rate x (decimal kurzy - 1)) - (1 - win rate). At 52% win rate on even-money bets (2.00 decimal), EV = (0.52 x 1.00) - 0.48 = 0.04 per unit staked, or 4% edge. A positive EV confirms the strategy has merit over a large sample.
Risk of ruin (RoR) estimates the probability of losing the entire bankroll before reaching the target. The approximation used here is: RoR = ((1-edge)/(1+edge)) ^ (bankroll / unit), where edge = EV / 1. This is a simplified model; actual RoR depends on the distribution of individual bet outcomes.
Zníženie jednotkovej stávky dramaticky znižuje RoR, ale tiež spomaľuje rast bankrollu. Neexistuje žiadne univerzálne optimálne nastavenie: záleží na tom, ako si ste istí svojim odhadom edge a aká je vaša tolerancia k riziku. Väčšina profesionálnych stávkarov používa 1 % až 3 % na stávku bez ohľadu na vnímanú výhodu.
This calculator uses flat stakes (same amount every bet). Kellyho kritérium staking adjusts unit size dynamically based on edge. The Kellyho kritérium calculator on this site lets you compare both approaches.

FAQ
What percentage of bankroll should I bet per game?
Väčšina profesionálnych stávkarov odporúča 1–3 % na stávku. 1 % je veľmi konzervatívne; 5 % je vysoké riziko. Čokoľvek nad 10 % na stávku dramaticky zvyšuje riziko bankrotu, aj pri kladnej výhode.
What is risk of ruin?
Riziko skazy je pravdepodobnosť straty celého bankrollu pred dosiahnutím cieľa zisku. Nižšie jednotkové stávky a väčšie bankrolly výrazne znižujú túto pravdepodobnosť.
How many bets do I need for a reliable edge estimate?
A minimum of 500-1,000 settled bets is generally needed to assess whether an apparent edge is real or attributable to variance. Smaller samples are not statistically reliable.
Should I use flat stakes or Kelly staking?
Flat stávkovanie je jednoduchšie a chráni pred preceňovaním výhody. Kelly staking je teoreticky optimálny, ale vyžaduje presné odhady pravdepodobnosti. Začiatočníci by mali začať s flat stávkami na 1–2 % za stávku.
Does a deposit bonus change my bankroll management?
Bonus funds typically come with požiadavky obratu. Factor only the portion of funds you consider truly yours when calculating unit stakes. Do not inflate your effective bankroll with locked bonus money.
