Moneyline Betting Explained: How Moneyline Odds Work

Moneyline betting is the simplest bet in sports: you pick who wins the game, and that's it. No point spread, no total. This guide explains how moneyline odds work, how to work out payouts and implied probability, and when a moneyline is a better or worse choice than the spread.

What Is a Moneyline Bet?

A moneyline bet is a wager on which team or player wins outright. If you back the Lions on the moneyline and they win by one point or by thirty, you win. The margin doesn't matter.

Every moneyline has two prices:

• The favorite carries a minus sign, like -150. That's how much you'd need to risk to win $100.
• The underdog carries a plus sign, like +130. That's how much you'd win on a $100 bet.

UK tipsters usually just call this a win bet or match betting.

How Moneyline Odds Work

Here is a typical NFL moneyline:

Team	Moneyline	Decimal odds	Profit on $100	Total return on $100
Favorite	-150	1.67	$66.67	$166.67
Underdog	+130	2.30	$130.00	$230.00

Betting the favorite

At -150, you risk $150 to win $100. Scaled down, a $100 bet wins $66.67. You get your $100 stake back too, so the total return is $166.67.

Betting the underdog

At +130, a $100 bet wins $130. Add your stake and you get $230 back.

Bigger gaps, bigger prices

The more lopsided the matchup, the bigger the numbers. A -300 favorite returns just $33.33 profit on $100. A +250 underdog returns $250 profit on $100. If you're new to the formats, our guide on how to read betting odds covers American, decimal and fractional side by side.

Moneyline Odds and Implied Probability

Every moneyline price hides a percentage: the chance of winning that the odds suggest. That's called implied probability.

• For a favorite: odds ÷ (odds + 100). At -150, that's 150 ÷ 250 = 60%.
• For an underdog: 100 ÷ (odds + 100). At +130, that's 100 ÷ 230 = 43.48%.

Implied probability is also your break-even win rate. If you only bet -150 favorites, you need to win more than 60% of them to make a profit. At +130, you need to win more than 43.48%.

You can check any price with the implied probability calculator.

Where the Vig Hides in a Moneyline

Add the two implied probabilities above: 60% + 43.48% = 103.48%. A fair market would add up to exactly 100%. The extra 3.48% is the sportsbook's margin, known as the vig.

Strip that margin out and the "fair" chances are about 57.98% for the favorite and 42.02% for the underdog. The no-vig calculator does this for you.

Why does this matter? Because small price differences add up. If one book has your team at -150 and another has them at -140, the -140 bet pays more for the exact same outcome. Checking several books before you bet, called line shopping, is one of the easiest ways to stop giving away value.

Moneyline vs Point Spread

The point spread asks a different question: does the favorite win by more than a set number of points? The moneyline only asks who wins.

	Moneyline	Point spread
What you need	Your team wins	Your team covers the margin
Price	Varies with the matchup	Usually close to -110 each side
Best for	Close games, live underdogs	Big mismatches
Risk on heavy favorites	High price, small return	Even price, but must win by enough

A few practical rules of thumb:

• Small favorites (say, -1.5 or -2.5 on the spread) are often priced only a little worse on the moneyline. Many bettors prefer the moneyline here because a narrow win still pays.
• Big favorites get expensive on the moneyline. One upset can wipe out several wins.
• Underdogs you think can win outright usually pay much more on the moneyline than on the spread.

Neither bet is better in general. The right one depends on the price and how you think the game will play out.

Moneyline Betting in Different Sports

NFL and college football

Overtime counts unless the bet says otherwise. An NFL regular-season game can still end in a tie after overtime. When that happens, standard two-way moneyline bets are usually graded as a push and your stake is returned. Playoff games keep going until there's a winner.

NBA and college basketball

Basketball has no ties, and overtime counts toward the moneyline. With big talent gaps, NBA favorites can get very expensive.

MLB and NHL

Baseball and hockey are usually bet on the moneyline because scoring is low. Run lines and puck lines exist, but the moneyline is the main market. Hockey books also offer a separate 60-minute (regulation) line that includes a draw option. Check your book's house rules for how overtime and shootouts are settled on each market.

Soccer

Soccer uses a three-way moneyline: home win, draw or away win. It's settled on 90 minutes plus stoppage time, so extra time doesn't count. If you back a team and the game ends level, you lose. Draw no bet removes the draw and refunds your stake if it ends level, at a shorter price.

Moneylines in Parlays

Moneylines are a common parlay building block. Two -150 favorites combined pay about +178, because 1.667 × 1.667 is about 2.78 in decimal odds. That looks appealing, but both legs must win and the vig compounds on each leg. Our guide on how parlay odds work explains the math in more detail.

How Cappers Post and Track Moneyline Picks

If you share picks, how you size and record moneyline bets matters for an honest record.

Risk units vs to-win units

There are two common ways to stake a moneyline:

• Risk 1 unit: At -150, you risk 1u to win 0.67u.
• To win 1 unit: At -150, you risk 1.5u to win 1u.

Both are fine. Just say which one you use and stick to it, so followers can check your numbers.

Why win rate alone can mislead

Moneyline records show why units and ROI matter more than wins and losses. Two simple examples, both risking 1u per bet:

Record	Price	Units won	ROI
7-3	-150 favorites	+1.67u	16.7%
5-5	+130 underdogs	+1.50u	15.0%

The 5-5 underdog record made almost as much as the 7-3 favorite record. A capper who only posts "7-3" without the prices is leaving out the important part. Our guide on how to track your betting record walks through units, ROI and win rate.

On TailMe, cappers can post moneyline picks as bet slips with the odds shown, and keep a self-reported record of units and ROI next to them, so followers see the prices as well as the results.

The short version

• A moneyline bet is a bet on who wins. The margin doesn't matter.
• Minus odds show what you risk to win $100. Plus odds show what you win on $100.
• Implied probability is your break-even win rate: 60% at -150, 43.48% at +130.
• The two sides add up to more than 100% because of the vig. Shop lines to keep more of it.
• Moneylines suit close games and live underdogs. Spreads suit big mismatches.
• Soccer uses a three-way moneyline with a draw, settled on 90 minutes plus stoppage time.
• Track moneyline picks in units with the prices included, not just wins and losses.
