What Does Spread Mean in Betting? How Plus and Minus Lines Work

A spread is a handicap in points: a number the sportsbook adds to one side's score before the bet is settled. The side with a minus lays the points and must win by more than that number; the side with a plus receives them and can lose by less than the number, or win. On the main line, the minus is usually on the favorite. On a whole-number line, landing exactly on the number is a push and the stake comes back; a half-point line cannot push. At -110, a spread bet breaks even only if you win 52.38% of the bets settled without a push.

This page covers the U.S. point spread in points: basketball and American football. In football (soccer), the whole-number and half-point logic is the same; for three-way and Asian handicaps, see the handicap glossary entry and Asian handicap settlement by half, corners and cards. Settlement depends on the market and period at your sportsbook; the operator rules below are one dated example.

How to read plus and minus spreads

A minus means your team must win by enough points to overcome the spread; a plus gives your team extra points for settlement. Read the sign and spread first, then check the odds separately: they describe different parts of the bet.

In the example from DraftKings Betting Rules, p. 7:

• Team A -7.5 must win by 8 points or more.
• Team B +7.5 covers by winning, tying or losing by 7 points or fewer.

The main-line favorite usually has the minus sign, while the underdog has the plus sign. In its guide What is Spread Betting? (viewed 17 Oct 2026), Covers.com describes the minus sign for the favorite, the plus sign for the underdog and a -110 price on both sides in its example. On alternate lines, the sign does not always point to the favorite; see the Alternate spread row in the neighboring-markets table below.

Here, a handicap is the score adjustment used to settle the bet. Similar markets are called the puck line in hockey and the run line in baseball. The name alone does not establish the settlement rules.

When a spread bet wins, pushes or loses

A bet covers the spread if your team is ahead after the adjustment, and loses if it is behind. A tie on a whole-number line produces a push when the market rules specify one.

In the table, Team A is home and Team B is away. Each cell shows net profit or loss, not total payout, assuming a $110 stake at -110. A push returns the $110 stake, leaving zero profit.

Step-by-step diagram: score 20-17, margin 3; a -3 spread gives 17 against 17, a push; a -3.5 spread gives 16.5 against 17, a lossTeaching diagram, not a bookmaker screen. Observation: at 20-17 the margin is 3 points. Conditional example: a -3 line pushes, a -3.5 line loses.

With a final score of 20:17, Team A -3 settles as 20 - 3 = 17 against 17. The adjusted scores are tied, so the payout is $110. At -3.5, the calculation becomes 20 - 3.5 = 16.5 against 17, so the bet loses.

This whole-number push rule appears in the Point Spread / Handicap market rules (DraftKings Betting Rules, copy hosted by the Massachusetts Gaming Commission, dated 1 Aug 2024, p. 7). Its example says a -3.0 bet pushes when the team wins by exactly 3 points. These are one operator's historical rules, not a universal condition across sportsbooks.

In the table, the whole-number line pushes at a margin of exactly 3. The half-point prevents an integer scoring margin from landing exactly on the line.

The two sides mirror each other: one wins and the other loses, or both push. Equal $110 bets on both sides of the same line at -110 produce a combined -$10 result: +$100 and -$110. If both push, the combined result is zero. That $10 illustrates the cost of the bookmaker margin in this pair of bets.

What -110 means and how often you need to win

-110 is American odds: you stake $110 to win $100 in net profit. A winning bet returns $210, including your stake. The odds are the price of the bet, not the point spread.

For a $110 stake:

• Win: $210 payout, +$100 net profit.
• Push: $110 payout, zero net profit.
• Loss: no payout, -$110 net result.

The decimal odds equivalent is 1.9091, rounded to 1.91. The calculations below use the original American odds of -110, not the rounded decimal price.

How to check the bookmaker margin

With -110 on both sides, the implied probabilities total 104.76%, giving a 4.76% bookmaker margin.

Open the implied probability calculator, select American odds and choose the "Two-way market" preset. For -110 and -110, it shows:

• "Booksum": 104.76%
• "Margin": 4.76%
• Implied probability for each side: 52.38%
• Probability for each side after removing the margin: 50.00%

These figures convert prices into probabilities; they do not predict the match result. Entering rounded decimal odds of 1.91 and 1.91 instead produces 52.36% per side, a 104.71% booksum and a 4.71% margin. The calculator page's reference table also uses rounded odds of 1.91.

How the price changes the break-even win rate

At -110, the break-even win rate is 52.38% among bets settled without a push, based on 110/(110+100). The key assumption is the price: moving to -115 raises the threshold to 53.49%, about 1.1 percentage points higher; at -120, it reaches 54.55%.

The same spread at different odds therefore offers different betting terms.

Under these assumptions—odds of -110 and a 50% win rate among bets settled without a push—the average result is -$5 per $110 stake; breaking even requires 52.38%. That average loss is -4.55% of the stake. At a 55% win rate, the average result would be +$5.50, but that accuracy is an assumption about your predictions, not a property of the market. An average result is not the payout from an individual bet.

Pushes do not change the break-even threshold among bets settled without a push. If, hypothetically, 10% of all bets pushed, wins would need to account for 47.14% of all bets while remaining 52.38% of bets settled without a push. This is a calculation example, not an observed push frequency.

How to check a push in the calculator

You can use the Asian handicap calculator to check whether the adjusted scores tie. Enter the example manually in the "Handicap" tab.

1. Under "Team you backed", choose "Home" for Team A. "Away" would represent Team B.
2. Enter -3 in "Handicap line".
3. Enter 1.9091 in "Odds", the decimal representation of -110 to the stated precision.
4. Enter 110 in "Stake".
5. Enter 20:17 in "Final score".

ToolsGambling Asian handicap calculator with handicap line -3, odds 1.9091, stake 110 and final score 20:17; outcome Push, payout 110, profit 0Screenshot of the ToolsGambling calculator (production site, 17 Oct 2026). On screen: Push and a payout of 110. Fields are labeled for football; the margin arithmetic is the same for points.

The result is "Outcome": "Push", "Payout": $110, and "Profit": +$0. This is a returned stake, not a winning bet.

The score field accepts values up to 20, which is why the example uses 20:17. This checks the arithmetic, not your sportsbook's basketball or other market rules.

Odds do not affect a push refund. For a winning bet, rounding does matter: entering 1.91 rather than the original -110 price would return $210.10 on a $110 stake, rather than $210.

How a spread differs from neighboring markets

A point spread adjusts the score to settle your selection. A moneyline does not apply that adjustment, while other markets can change the available outcomes, split the stake or combine separate bets.

A three-way handicap does not settle like an ordinary spread with a push. In DraftKings' example, a team at -1 must win by two goals or more for that selection to win; a win by exactly one goal makes the tie selection win instead.

UK financial spread betting is also distinct from the fixed-risk, fixed-payout sports bet described here. Its profit and loss depend on how far the market moves. Top End Sports, topendsports.com, makes this distinction in its overview.

What to check before betting

Check the exact market, settlement period, overtime treatment, line, odds and push rules at your sportsbook. The word “spread” does not establish every settlement condition.

• Period. DraftKings' cited rules, p. 7, generally cover the listed period from start to finish. Some soccer Asian handicap offers instead count only the score from bet placement to the end of the period. Those offers are flagged with the score at placement.
• Overtime. The same operator's basketball rules, p. 41, include overtime unless otherwise stated. If overtime is played only for qualification, bets settle without it. Do not automatically apply that condition to another sport or sportsbook.
• Line and price. -3 and -3.5 settle differently when the team wins by exactly 3 points. -110 and -115 require different break-even win rates.
• Pushes in parlays. Under the cited operator rules, p. 13, a pushed selection is removed and the odds are recalculated for the remaining selections.
• Meaning of the threshold. The 52.38% break-even win rate at -110 is a requirement imposed by the price, not evidence that your predictions achieve that accuracy.

First establish which score and period count, then apply the spread, and finally check the payout using the odds.
