What Is an Over/Under Bet?

An over/under bet is a wager on whether the total score of a game will be over or under a number set by bookmakers.

For example:

Total line: 2.5 goals
If you bet Over, you win if total goals = 3 or more
If you bet Under, you win if total goals = 2 or less

This type of betting does not depend on which team wins — only on the total outcome.

Manually calculating betting returns and probabilities can be confusing, especially when dealing with different odds formats like American, decimal, or fractional.

This tool helps you:

✔ Save time
✔ Avoid calculation mistakes
✔ Understand your risk vs reward
