This article answers a common, practical question: what does the plus or minus mean on a betting line. Readers will get concise definitions for moneylines, point spreads, and totals, see the standard American-odds formulas, and follow short examples they can use to compute payouts by hand or in a spreadsheet. The goal is clarity. If you are a sports fan, analyst, or participant in skill-based prediction challenges, understanding these signs helps you read boards quickly and make consistent forecasts. The explanations below use plain language and step-by-step math so you can apply them immediately.

Plus and minus signs show either which side is favored or the American-odds price attached to a wager.

On moneylines, minus = amount to risk to win 100 and plus = profit from a 100 stake.

Totals list a points threshold; the adjacent +/- is usually the odds price not a points change.

how does line betting work: quick definition and core terms

The phrase how does line betting work asks a simple question with a few consistent answers: plus and minus signs show either which side is favored or the price you get when you place a wager. In most U.S. markets a minus sign next to a team marks the favorite, and a plus sign marks the underdog, which helps readers immediately recognize which side carries higher implied probability or higher potential payout Investopedia moneyline explanation.

Lines appear in a few common formats: moneyline, point spread, and total or over/under. The same plus or minus characters reappear in each format but mean different things depending on whether they are attached to a team name, a points number, or the odds price next to an Over or Under option Investopedia point spread guide.

Core terms to keep handy: favorite and underdog describe expected outcome; moneyline is a straight win/loss price; point spread is a points adjustment that determines whether a team covers; total or over-under is the projected combined points threshold for the game Investopedia over/under primer.

how does line betting work: reading the moneyline plus and minus

On a moneyline the plus and minus give you a direct sense of risk and reward. A minus number shows how much you must risk to win 100, and a plus number shows how much profit a 100 stake would return; those conventions make it easy to compare favorites and underdogs at a glance Investopedia American odds.

Read the negative value as the amount you would need to stake to win 100, and read the positive value as the profit from a 100 stake. For example, a listed -150 indicates a stronger team where the bettor risks 150 to win 100; a listed +200 indicates a less likely outcome that would pay 200 on a 100 stake. Use the signs to compare implied probabilities between options without doing a full calculation Investopedia moneyline explanation.

To turn those signs into a quick calculation, follow the American odds rules: for positive odds calculate profit by multiplying stake by odds over 100; for negative odds calculate profit by multiplying stake by 100 divided by the absolute value of the odds. Practicing these two steps makes it straightforward to check any moneyline price on a sportsbook screen Investopedia American odds.

Point spreads: what a negative or positive number means for covering the spread

Point spreads use plus and minus to show which team is treated as the favorite on points. A negative spread means that team must win by more than the spread to "cover," while a positive spread gives the underdog room to lose by less than the margin or win outright and still cover Investopedia point spread guide.

For example, a -3.5 favorite must win by at least four points to cover, while the +3.5 underdog covers by winning or by losing by three points or fewer. Bookmakers often use halves to avoid pushes, so you typically see .5 increments that create clear win or loss outcomes for spread bets Massachusetts Gaming Commission primer.

What does the +/- mean on betting lines and how does it affect payouts?

The +/- on lines either marks which side is favored or indicates the American-odds price for a wager; use the American-odds formulas to compute profit and total payout and treat totals as point thresholds with the adjacent sign representing price.

Understanding cover rules is key when you decide whether to back a favorite on the spread or choose the underdog. Consider how a team tends to finish games and whether late scoring could flip a close spread result Investopedia point spread guide.

Totals and over/under: the plus/minus next to totals is the price, not a change in points

Totals list a projected number for combined scoring, such as 47.5, and the plus or minus shown alongside Over or Under normally represents the American-odds price for that choice, not an adjustment to the point total itself Investopedia over/under primer.

When you see Over 47.5 -110, the 47.5 is the threshold you are betting on, and -110 is the price you will get for either side. That price affects break-even percentages and the payout you receive if the combined score ends up above or below the listed number Investopedia American odds.

To settle an Over/Under you compare the game total to the line number; then you apply the odds price to figure profit and total return. Because totals are framed as a points threshold, do not treat the plus or minus next to the Over/Under number as an increase or decrease in points Investopedia over/under primer.

Three-way lines and soccer: how plus and minus work with draw outcomes

Soccer often uses a three-way moneyline that lists prices for home win, draw, and away win separately. Each outcome carries a plus or minus that functions as the American-odds price for that specific result, and the draw appears as its own priced option rather than tying two team outcomes together Investopedia three-way moneyline guide.

Because there are three mutually exclusive outcomes, payouts must be read individually: a draw priced at +250 pays differently than a home win at -120 or an away win at +320. Read each sign as the price for that outcome and compute profit using the standard American-odds formulas Investopedia American odds.

How payout math works for American odds: step-by-step formulas

The rules for calculating winnings are consistent: for positive American odds, winnings equal the stake multiplied by odds divided by 100; for negative odds, winnings equal the stake multiplied by 100 divided by the absolute value of the odds. Add the stake to winnings to get total payout Investopedia American odds. For quick checks you can also use external converters such as Covers odds converter.

As a quick formula: positive odds -> profit = stake × (odds / 100); negative odds -> profit = stake × (100 / |odds|). Total payout = stake + profit. Practicing these two formulas for a few different lines helps you check bookmaker displays or your own spreadsheet quickly Investopedia moneyline explanation.

How lines are presented across major U.S. sports and common price conventions

Across major U.S. sports such as NFL and NBA, bookmakers commonly present spreads and totals with a -110 style price. That -110 is a standard vigorish or juice convention that adjusts the payout to include the bookmaker's margin, and you should expect similar sign and price conventions across leagues Investopedia American odds.

The consistency of sign rules means that whether you look at an NFL board or an NBA slate, a minus next to a team still denotes the favorite and a plus still denotes the underdog. Recognizing this common format reduces confusion when you move between sports or between different bookmakers' displays Investopedia point spread guide.

Decision criteria: what to consider when a line shows plus or minus

When a moneyline is negative that implies a higher implied probability and therefore less potential profit per stake, while a positive line implies lower implied probability and greater potential profit. Use those signals when weighing risk-adjusted plays and comparing options Investopedia moneyline explanation.

Before acting on a line, compare implied probability, bankroll impact, matchup context, and recent line movement. Always translate prices into implied break-even percentages and consider how much of your simulated or real bankroll you want to risk at that price rather than focusing solely on the sign Investopedia American odds.

Include common price formats like -110 on spreads and totals when sizing stakes so you account for juice in your risk calculations. That habit helps create consistent, disciplined decisions instead of ad-hoc guesses about value Investopedia point spread guide.

Common mistakes and pitfalls when interpreting plus and minus signs

A frequent error is treating the +/- beside a total as a change to the point number rather than the odds price. Totals are a points threshold; the sign next to Over or Under is the price you will get on that choice, so check the label carefully before you calculate payouts Investopedia over/under primer.

Another common pitfall is ignoring the effect of juice, often displayed as -110, which raises the break-even percentage above 50 percent for even-money markets. Accounting for vigorish is necessary to judge whether a line actually offers value Investopedia American odds.

Finally, misreading a three-way soccer board as a two-way contest will give you incorrect expectations about frequency of payouts. Remember that draws are a separate outcome in three-way markets and are priced independently of the two teams Investopedia three-way moneyline guide.

Practical examples and scenarios: three worked examples you can follow

Example 1 - Moneyline favorite and underdog. Suppose a favorite is listed at -150 and the underdog at +200. If you stake 100 on the favorite, profit = 100 × (100 / 150) = 66.67, so total payout = 166.67. If you stake 100 on the underdog at +200, profit = 100 × (200 / 100) = 200, so total payout = 300 Investopedia American odds.

Example 2 - Spread bet with -3.5. If Team A is -3.5, Team A must win by 4 or more points to cover. If Team A wins by three points, the favorite fails to cover and the +3.5 underdog covers; halves such as .5 remove pushes and create clear outcomes for each side Investopedia point spread guide.

Example 3 - Over/Under example with -110 pricing. For Over 47.5 at -110, a common stake is 110 to win 100, or 10 to win about 9.09. Using the positive/negative formulas, a 10 stake at -110 yields profit = 10 × (100 / 110) = 9.09, total payout = 19.09 Investopedia over/under primer.

What does a minus sign mean on a moneyline?

A minus sign marks the favorite and shows how much you must risk to win 100; the number indicates the stake required for a 100 profit.

Does a plus next to a total change the point number?

No. The plus or minus next to a total is usually the odds price for Over or Under, not an adjustment to the point threshold.

How do I compute winnings from American odds?

For positive odds multiply stake by odds divided by 100; for negative odds multiply stake by 100 divided by the absolute value of the odds, then add stake for total payout.
