Calculators & Market Tools — Key Questions Answered
How much does lower vig really matter over a season?
Enormously. Dropping your average price from -115 to -105 (such as during YouWager's Friday 5% Football Juice Special or MLB True Dime Line) lowers your break-even win rate by more than two full percentage points—often the entire margin between a losing bettor and a profitable one.
What does a $0.62 contract price on a prediction market mean?
It represents a 62% raw implied win probability, which converts to approximately -163 in American odds or 1.61 in decimal odds.
Which calculator should every bettor bookmark first?
The No-Vig Fair Odds Calculator and the Kelly Criterion Calculator. Together they tell you whether a line has mathematical value and exactly how much to stake.
