Over/Under Tool
Payouts for totals markets from the line, both prices and your stake.
How to Use This Calculator
- Pick your odds format
- Input the line (e.g., 2.5 goals or 47.5 points)
- Input the over and under odds
- Input your stake
- Read payouts, profits and margin
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
What are over/under bets?
Over/under (totals) bets wager on whether the combined score, goals or points lands higher (over) or lower (under) than a posted line. Lines like 2.5 (soccer) or 47.5 (NFL) are most common; the .5 rules out a push.
What if the score lands exactly on the line?
If the line is a whole number (e.g., 2.0) and the total hits it exactly, the bet pushes — stake refunded, no profit. Half-point lines (.5) avoid this. Quarter lines (.25, .75) split your stake, so half pushes and half wins or loses.
Why are over/under odds usually near -110?
Books set the line to pull roughly equal action both ways. The -110 odds (1.91 decimal) carry the standard 4.5-5% bookmaker margin. Sharp books may post -105 or even -102 on top markets.
How do I find value in totals?
Stack the book’s line against a model — Poisson for soccer, points-per-possession for basketball. If your projection beats the line by more than the margin, that can signal value. Always shop multiple books for the best line and price.
