Bankroll management calculator
How this calculator works
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 tét 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 tét. 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 szorzók - 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 tétd, or 4% edge. A positive EV erősítsd megs the strategy has merit over a large sample.
Risk of ruin (RoR) estimates the valószínűség 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.
Reducing unit tét reduces RoR dramatically but also slows bankroll growth. There is no universally optimal setting: it depends on how confident you are in your edge estimate and how risk-tolerant you are. Most professional bettors use between 1% and 3% per bet regardless of perceived edge.
This calculator uses flat téts (same amount every bet). Kelly criterion staking adjusts unit size dynamically based on edge. The Kelly criterion calculator on this site lets you compare both approaches.

Gyakori Kérdések
What percentage of bankroll should I bet per game?
Most professional bettors recommend 1-3% per bet. 1% is very conservative; 5% is high risk. Anything above 10% per bet dramatically increases the chance of ruin, even with a positive edge.
What is risk of ruin?
Risk of ruin is the valószínűség of losing your entire bankroll before reaching your nyereség target. Lower unit téts and larger bankrolls reduce this valószínűség significantly.
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 téts are simpler and protect against overestimating edge. Kelly staking is theoretically optimal but requires accurate valószínűség estimates. Beginners should start with flat téts at 1-2% per bet.
Does a deposit bonus change my bankroll management?
Bonus funds typically come with fogadási követelmények. Factor only the portion of funds you consider truly yours when calculating unit téts. Do not inflate your effective bankroll with locked bonus money.
