How Do Betting Odds Work? What Does 1+ Mean in Betting Explained
Understanding betting odds is a useful first step for anyone thinking about placing a bet. Odds show both how a bookmaker rates the chance of an outcome and what a payout might look like.
You will see odds presented in different formats, and you will often spot the label “1+”, especially in football markets. It looks simple, yet it can be misread if the rules are not clear.
This blog post breaks down how odds relate to implied probability, the differences between decimal, fractional and American formats, and what “1+” means in real match scenarios. If you choose to bet, set a budget that suits you and use safer gambling tools where needed.
How Do Betting Odds Translate To Implied Probability?
Betting odds do more than show potential returns; they also reflect the bookmaker’s view of how likely an outcome is. That view, converted into a percentage, is called implied probability.
For decimal odds, implied probability equals 1 divided by the decimal, multiplied by 100. At 2.00 the implied probability is 50%, while 4.00 implies 25%. For fractional odds a/b, use b divided by a plus b, then multiply by 100. Evens (1/1) gives 50%, and 4/5 works out at about 55.6%.
Remember that bookmakers build in a margin so the combined probabilities across all outcomes usually add up to more than 100%. With that picture in mind, it helps to see how each odds format presents the same idea in a different way.
Understanding Decimal, Fractional and American Odds
Betting odds are commonly shown in decimal, fractional or American formats. The event is the same; only the way potential returns are displayed changes.
Decimal odds show the total return per £1 staked, including the stake. At 3.00, a £1 winning bet returns £3 in total.
Fractional odds show profit relative to stake. At 5/1, every £1 staked returns £5 profit plus the £1 stake. At 1/2, a £2 stake returns £1 profit plus the stake.
American odds use plus or minus numbers. A positive figure such as +200 shows the profit from a £100 stake, so +200 means £200 profit on £100. A negative figure such as -150 shows how much needs to be staked to make £100 profit.
Once you are comfortable reading these formats, the shorthand you see in football markets, like “1+”, starts to make far more sense.
What Does 1+ Mean In Betting Markets?
The term “1+” appears widely in football betting and simply means at least one of a specified event must happen for the selection to win. It does not cap the total; it just sets the minimum.
Common Uses Of 1+ Across Football Markets
You will see “1+ goals” for the match, “1+ corners” for a team, or “1+ booking” in a half. The same idea extends to player stats such as “Player X to have 1+ shots on target.” In every case, one or more is enough for that part of the bet to be settled as a winner.
These markets are popular because they focus on whether an event occurs at all, rather than asking for an exact total or a high threshold.
How Bookmakers Display 1+ On A Betting Slip
Bookmakers show “1+” in the market title or directly alongside the selection, for example “Team A 1+ corners” or “Player X 1+ fouls committed.” In Bet Builder-style markets, several “1+” selections can be combined, and each needs to land for the overall bet to win. Settlement usually relies on an official data source, which is listed in the market rules.
How Does 1+ Affect Payouts And Returns?
Because “1+” only asks for a minimum of one event, it is typically priced shorter than higher thresholds such as “2+” or “3+.” The price reflects the higher likelihood of at least one event occurring compared with two or more.
Payouts follow the usual rules for the odds format you selected. If a “1+ goals” leg is part of an accumulator or a Bet Builder, its contribution to the return is folded into the combined odds, and the overall bet only pays if every leg wins.
This is why it helps to read the market description closely and check whether the “1+” refers to the whole match, a single team, a player, or a time period such as the first half. That detail directly affects both the price and the potential return. Which leads neatly to working out the numbers on your slip.
How To Calculate Winnings From Odds
With decimal odds, total return equals stake multiplied by the decimal price, and that figure already includes the stake. A £5 bet at 2.50 returns £12.50 in total.
With fractional odds a/b, profit equals stake multiplied by a divided by b, and total return is profit plus the original stake. A £5 bet at 3/1 returns £15 profit and £20 in total.
With American odds, a positive price such as +200 means profit equals stake multiplied by 200 divided by 100, so a £5 stake returns £10 profit and £15 in total. A negative price such as -150 means profit equals stake multiplied by 100 divided by 150; a £5 stake returns £3.33 profit and £8.33 in total. Of course, those numbers move.
How Do Odds Change Before And During A Match?
Odds are updated as information changes. Before kick-off, prices can move with team news, tactics, or weather. If a leading striker is ruled out, the market adjusts to reflect the reduced chance of certain outcomes.
In play, odds react to match events. An early goal may see prices for the favourite shorten in the match result market, while totals-based lines such as “1+ goals” can be settled quickly once the qualifying event occurs. Injuries, red cards and sustained pressure can all move prices, and traders update them to reflect the state of the game.
Because notation can be brief, it is easy to read it the wrong way if the context is missed.
Common Misinterpretations Of 1+ And How To Avoid Them
A frequent misunderstanding is reading “1+” as “exactly one.” It always means one or more. If the minimum is reached, the condition is met.
Scope is another area that trips people up. “1+ goals” may cover the entire match for either team unless it specifies a team or player. Where the market states “Team A 1+ corners” or “Player X 1+ shots on target,” the event must be recorded for that team or player.
Time periods matter too. Some markets apply to the first half, a specific 15-minute interval, or injury time only. Extra time is not usually included in 90-minute markets unless stated.
Finally, settlement depends on how events are recorded. Own goals count towards total goals, but technical stats like shots on target or fouls are graded by the named data provider, and cards shown to coaches do not usually count in player booking markets. Reading the market notes avoids surprises.
A few short scenarios make it clearer.
Examples: Reading 1+ In Real Match Scenarios
“1+ Goals in the Match” wins with any scoreline other than 0-0. A 1-0, 2-1 or 3-3 all meet the condition.
“1+ Corners for Team A” needs Team A to be awarded at least one corner. If they record none while the opponents have several, the selection loses.
“Player X to have 1+ Shots on Target” pays if the official stats provider records at least one on-target attempt for that player. Shots that are blocked before reaching the goal or go wide do not count.
A Bet Builder might combine “1+ goals,” “Team A 1+ corners” and “Player X 1+ fouls committed.” All three must occur for the bet to be settled as a winner, and the combined odds reflect the chance of the trio landing together.
