This article explains what the plus and minus numbers mean in NHL odds and walks through how to convert American moneyline prices into payouts and implied probabilities. It is written for sports enthusiasts and prediction-minded readers who want practical, step-by-step methods rather than jargon. You will learn the difference between moneyline and puck line wagers, see worked examples, and get a short checklist you can use when evaluating market prices.

In American moneyline odds, a minus sign denotes the favorite and shows how much to stake to win 100, while a plus sign shows profit on a 100 stake.

The puck line is usually set at +/-1.5 goals and changes the win condition from who wins to whether a team covers the goal spread.

What the plus and minus numbers mean in NHL odds, how to bet on hockey

When you see a plus or minus next to a team in an NHL odds board, the symbols tell you who is the underdog and who is the favorite, and they map directly to how payouts are calculated. In North American markets this convention is part of American, or moneyline, odds where a minus sign marks the favorite and a plus sign marks the underdog; that notation and its meaning are summarized in industry education sources and glossaries, which explain that negative numbers show how much you must risk to win one hundred and positive numbers show profit on a one hundred stake Investopedia moneyline guide.

In practical terms, a minus sign before a number means the team is favored and the number indicates the amount you would have to risk to make a fixed profit, while a plus sign shows how much you would profit on a standard stake. This representation is the default for many NHL markets across North America and helps bettors quickly see which side the market expects to win American Gaming Association betting glossary.

How American odds map to payouts and implied probability

American odds convert directly into a payout formula you can apply by hand. For a positive price noted as +A, profit equals stake times A divided by one hundred; for a negative price noted as -B, profit equals stake times one hundred divided by B, and total return is stake plus profit. This payout math is standard in educational resources on moneyline bets Investopedia moneyline guide.

To compare market prices across matches you can convert American odds into an implied probability. For positive odds the formula is one hundred divided by A plus one hundred, written as 100/(A+100). For negative odds the formula is B divided by B plus one hundred, written as B/(B+100). These formulas let you put every price on the same percentage scale so you can compare it to your model or expectation Implied probability formulas explained.

Worked example one: a price of +150 on a team. Using the payout formula, a 100 stake returns a profit of 100 times 150 divided by 100, which is 150, for a total return of 250. For implied probability, use 100 divided by 150 plus 100, so 100/250 equals 0.40, or 40 percent implied chance according to the market Investopedia moneyline guide.

Worked example two: a price of -200. For a 100 stake the profit equals 100 times 100 divided by 200, which gives 50, so total return is 150. The implied probability formula for negative odds is B divided by B plus 100, so 200/(200+100) yields about 0.667, or 66.7 percent implied chance for the favorite Implied probability formulas explained.

Short summary: use the plus/minus sign to choose the correct payout formula, compute profit as stake times the ratio shown above, and convert to a percent with the implied probability formulas when you want to compare prices across markets.

What the puck line is and how +1.5 and -1.5 work

The puck line is the NHL equivalent of a point spread; it applies a goals margin to the final score, and the default puck line is commonly set at plus or minus one point five goals. When a team is listed at -1.5 that team must win by two or more goals after regulation, overtime, and any settlement rules the operator uses in order for a -1.5 wager to cover, while a +1.5 team can lose by a single goal or win outright and still cover the line iGaming Ontario puck line explanation.

Compared with the moneyline, the puck line changes the win condition from who wins the game to whether a team covers the goal spread, so the same matchup can have different payout profiles depending on whether you choose moneyline or puck line. For the favorite, covering -1.5 is a harder requirement than simply winning, and that difficulty usually shows up as a larger payout for the puck line favorite than for the moneyline favorite in the same game Covers puck line guide.

When reading a puck line price remember that the number beside the plus or minus is not a direct money return like a moneyline price; it is the price you will use in the same American odds math once you determine whether the spread is covered or not.

Step-by-step: calculate payouts and convert odds to probability

Follow these steps when you want to compute profit and implied probability from an American price. Step 1, identify the sign: if the odds carry a plus sign use the positive formula, if they carry a minus sign use the negative formula. This first identification is the simplest preventive measure against formula errors and is a core rule in moneyline explanations Investopedia moneyline guide.

Step 2, apply the right profit formula. For a positive price +A, profit equals stake times A divided by 100. For a negative price -B, profit equals stake times 100 divided by B. Step 3, compute total return by adding stake to profit. Step 4, convert the displayed price to implied probability using either 100/(A+100) for positive odds or B/(B+100) for negative odds so you can compare the market price to your expected chance Implied probability formulas explained.

Example calculation one, positive price: you place a 50 stake on +200. Profit equals 50 times 200 divided by 100, which is 100, so total return is 150. The market implied probability is 100/(200+100), or about 33.3 percent. Example calculation two, negative price: you place a 75 stake on -150. Profit equals 75 times 100 divided by 150, which is 50, so total return is 125. The market implied probability is 150/(150+100), or 60 percent Investopedia moneyline guide.

Short checklist you can copy: 1) identify sign, 2) use the plus or minus payout formula, 3) add stake to get total return, 4) apply the appropriate implied probability formula, 5) compare that percent to your model or expected chance.

Rules that change how wagers settle: overtime, shootouts, and operator variations

Settlement rules can change whether a market counts overtime or a shootout in its definition of the game winner or in how a puck line is applied; different operators and jurisdictions sometimes have specific provisions that affect a ticket's final result, so always check the house rules before you rely on a calculation.

What do the plus and minus numbers beside NHL teams indicate and how do they affect payouts?

They show which team is favorite or underdog in American moneyline odds; a minus shows how much you must stake to win a fixed amount and a plus shows profit on a standard stake, and both can be converted to implied probability for comparison.

For example, some operators explicitly state that moneyline bets settle on the final result after overtime and shootout, while others may settle only on regulation results for specific markets. These operational differences do not change the math of American odds and implied probability, but they do change how a particular wager resolves in practice American Gaming Association betting glossary.

When to consider the moneyline versus the puck line in NHL markets

The core tradeoff between moneyline and puck line is simple: moneyline pays on the game winner regardless of margin, while the puck line requires a margin of victory or gives the underdog a margin cushion, and that changes expected payout and risk. This distinction is fundamental to choosing the market that fits your forecast and risk tolerance iGaming Ontario betting guide.

Decision criteria to weigh: if your model or judgment suggests a team will win but only by a narrow margin, the moneyline is the obvious choice; if you expect a clear multi-goal outcome, the puck line may offer better value because favorites that need to cover -1.5 often carry larger payouts than the moneyline favorite for the same matchup Covers puck line guide.

Also consider bankroll impact. Puck line prices can offer higher upside for favorites because of the tougher cover condition, but they also increase variance if your expectations on margin are off. Use implied probability to compare the market price with your model before committing funds or trying a prediction challenge.

Common mistakes and pitfalls when reading NHL +/- odds

A frequent mistake is mixing up the profit formulas for positive and negative odds. One simple tip to avoid this error is to write the sign and the formula on the same line when you calculate; that visual cue reduces the chance of applying the wrong ratio and is a core procedural check endorsed in educational materials Implied probability formulas explained.

Another pitfall is assuming puck line and moneyline settle identically. Treat them as different instruments: moneyline is margin-agnostic, puck line is margin-dependent, and conflating the two leads to wrong payout expectations and mispriced comparisons iGaming Ontario betting guide.

Finally, ignoring an operator's overtime or shootout rules can flip a calculation's outcome. Always confirm settlement terms for the specific market and operator before relying on implied probability comparisons or publishing a prediction.

Practical examples and scenarios: step-by-step math for sample NHL matchups

Worked scenario one, moneyline example. Suppose Team A is listed at -180 on the moneyline and you stake 100. Using the negative payout formula, profit equals 100 times 100 divided by 180, which gives about 55.56, so total return is 155.56. The implied probability is 180 divided by 180 plus 100, or 180/280, which equals about 0.643, or 64.3 percent implied chance from the market Investopedia moneyline guide.

Interpretation: if your analysis gives Team A a higher chance than 64.3 percent to win outright, the moneyline price may offer positive expected value; if your model gives a lower probability, the market price likely overstates the favorite's chance.

Worked scenario two, puck line example. Suppose Team B is the favorite and offered at -1.5 with American odds of -120 on the puck line while the moneyline for Team B is -140. Covering -1.5 requires Team B to win by two or more goals, so the puck line payout may be larger than the moneyline reflects because the probability of covering is lower than the probability of simply winning. When you compute implied probability from the puck line price and compare it to your model's estimate of the chance the favorite wins by two or more, you can assess whether value exists Covers puck line guide.

How to use implied probability to compare to your model: compute the market percent for the displayed odds, estimate your model percent for the same event, subtract market percent from model percent to get a simple edge estimate, and then weigh that edge against your bankroll rules and confidence to decide whether to act.

Summary and next steps

Key takeaways: plus signs identify underdogs and show profit on a 100 stake, minus signs identify favorites and show how much you must risk to win 100; use the positive and negative payout formulas to compute profit and total return, and convert American odds to implied probability to compare market prices across matches Investopedia moneyline guide.

What does a negative number mean in NHL odds?

A negative number shows the favorite and indicates how much you must risk to win 100; use the negative payout formula to compute profit and total return.

How does the puck line differ from the moneyline?

The puck line applies a goals spread, typically +/-1.5, so it depends on margin of victory rather than just who wins the game.

How do I convert American odds to implied probability?

For positive odds use 100/(A+100); for negative odds use B/(B+100); the result is the market's implied percentage chance.

If you want to practice these conversions, run the worked examples above with your own stakes and compare the market implied percentages to your forecasts.
