Formula
Payout = Stake × Decimal Odds
Margin = (1 / Over Odds) + (1 / Under Odds) − 1
Lines ending in .5 cannot push. Lines on whole numbers (2.0, 47.0) push if the total lands exactly on the line — the stake is returned.
Frequently Asked Questions
Define over/under bets.
Over/under (totals) bets wager on whether combined score, goals or points exceed (over) or fall short of (under) a posted line. Common lines are 2.5 (soccer) or 47.5 (NFL); the .5 rules out a push.
What if the score lands exactly on the line?
On a whole-number line (e.g. 2.0) an exact match pushes and refunds your stake with no profit. Half-point lines (.5) eliminate this. Quarter lines (.25, .75) split the stake so half pushes and half wins or loses.
Why are over/under odds usually near -110?
Books set the line to draw roughly even action on both sides. -110 (decimal 1.91) reflects the standard 4.5-5% margin. Sharp books may post -105 or even -102 on top markets.
How is value found in totals?
Compare the book’s line to a model — Poisson for soccer, points-per-possession for basketball. A projection diverging from the line by more than the margin can signal value. Always shop multiple books for the best line and odds.
