Time to Target Calculator

Calculate how long it will take to reach a bankroll target and the probability of getting there.

Your current bankroll.
Your bankroll goal.
Your expected win rate advantage per bet.
Your standard bet amount.
SD per unit bet. Blackjack ~1.15, even money ~1.0.

Formulas:
Expected bets = profit_needed / (edge × bet_size)
P(target before ruin) = 1 - ((1-e)/(1+e))^(bankroll/unit) for classic model
More precisely using Gambler's Ruin: P = (1 - ((q/p)^a)) / (1 - ((q/p)^(a+b)))
where a = current_units, b = profit_units, p = win prob, q = loss prob
