Bankroll management calculator
Kako deluje ta kalkulator
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 kvote - 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.
Zmanjšanje enote stavnice dramatično zmanjša tveganje propada, a upočasni rast bankrolla. Splošno optimalne nastavitve ni: odvisno je od tega, kako zaupate svoji oceni prednosti in koliko tveganja ste pripravljeni sprejeti. Večina poklicnih stavničarjev ne glede na zaznano prednost uporablja med 1 % in 3 % na stavo.
This calculator uses flat stakes (same amount every bet). Kellyjev kriterij staking adjusts unit size dynamically based on edge. The Kellyjev kriterij calculator on this site lets you compare both approaches.

FAQ
What percentage of bankroll should I bet per game?
Večina profesionalnih stavnih igračev priporoča 1-3% na stavo. 1% je zelo konzervativno; 5% je visoko tveganje. Karkoli nad 10% na stavo drastično poveča tveganje propada, tudi ob pozitivni prednosti.
What is risk of ruin?
Tveganje propada je verjetnost izgube celotnega bankrolla pred dosego cilja dobička. Nižje enote stavnic in večji bankrolli to verjetnost bistveno zmanjšajo.
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?
Fiksne stavnice so enostavnejše in ščitijo pred precenjevanjem prednosti. Kellyjevo stavničarstvo je teoretično optimalno, a zahteva natančne ocene verjetnosti. Začetniki naj začnejo s fiksnimi stavnicami pri 1–2 % na stavo.
Does a deposit bonus change my bankroll management?
Bonus funds typically come with zahteve za stavljenje. Factor only the portion of funds you consider truly yours when calculating unit stakes. Do not inflate your effective bankroll with locked bonus money.
