Sådan fungerer denne beregner

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 odds - 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.

At reducere enhedsindsatsen reducerer RoR dramatisk, men bremser også bankroll-væksten. Der er ingen universelt optimal indstilling: det afhænger af, hvor sikker du er på dit kantestimat, og hvor risikovillig du er. De fleste professionelle spillere bruger mellem 1% og 3% pr. vad uanset opfattet kant.

This calculator uses flat stakes (same amount every bet). Kelly-kriteriet staking adjusts unit size dynamically based on edge. The Kelly-kriteriet calculator on this site lets you compare both approaches.

FAQ

What percentage of bankroll should I bet per game?

De fleste professionelle sportsspillere anbefaler 1-3% pr. spil. 1% er meget konservativt; 5% er høj risiko. Alt over 10% pr. spil øger dramatisk chancen for ruin, selv med en positiv fordel.

What is risk of ruin?

Ruineringsrisiko er sandsynligheden for at miste hele din bankroll, inden du når dit profitmål. Lavere enhedsindsatser og større bankrolls reducerer denne sandsynlighed betydeligt.

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?

Flade indsatser er enklere og beskytter mod at overvurdere kanten. Kelly-indsats er teoretisk optimalt, men kræver nøjagtige sandsynlighedsestimater. Begyndere bør starte med flade indsatser på 1-2% pr. vad.

Does a indbetalingsbonus change my bankroll management?

Bonus funds typically come with omsætningskrav. Factor only the portion of funds you consider truly yours when calculating unit stakes. Do not inflate your effective bankroll with locked bonus money.
