Direct answer
Over/Under is a market in which you try to predict whether the total number of goals in a match will be above or below a line.
In football, the most common example is Over 2.5 goals: 3 or more goals are needed for it to hit.
Quick summary
| Also known as | Total goals, Over/Under goals. |
|---|---|
| Main logic | Betting on whether the match will have more or fewer goals than a line. |
| Over 2.5 hits | When the match has 3 or more goals. |
| Under 2.5 hits | When the game has 0, 1, or 2 goals. |
| Common mistake | Assuming an open game is enough, without looking at the line, odd, and context. |
How does Over/Under work?
The bookmaker sets a line and you choose a side:
- Over: the game total stays above the line.
- Under: the game total stays below the line.
Market, line, and odd are different things: market is Over/Under, line is 2.5 or 3.5 goals, and odd is the price paid for that side.
Logic and formulas
Over X = total goals in the match > X Under X = total goals in the match < X Implied probability = 1 / decimal odd EV = (estimated probability x odd) - 1Since there is no half goal, the 2.5 line makes the reading straightforward:
| 0, 1, or 2 goals | Under 2.5 wins. |
|---|---|
| 3 or more goals | Over 2.5 wins. |
Example in football
If Over 2.5 is at odd 1.90, the approximate implied probability is 52.6%.
Implied probability = 1 / 1.90 = 52.6% EV with an estimated chance of 58% = (0.58 x 1.90) - 1 EV = +10.2%In this example, Over 2.5 has positive EV because the offered odds exceed the fair price implied by the estimated probability.
