Demystifying the Difference Between Spread and Moneyline Sports Bets

As an experienced sports bettor and data analyst, I’m often explaining the inner workings of spreads and moneylines to friends just getting started in sports betting. They usually have numerous questions about how these two popular betting options differ and when to use each. In this beginner’s guide, I’ll use my expertise to break down everything you need to know about picking between spread and moneyline wagers.

A Brief History of Spread and Moneyline Wagering

Before diving into the intricacies of spreads versus moneylines, let’s look back at the origins of each betting method. This provides helpful context for understanding why each exists in sports betting today.

The Point Spread – While disputed, the commonly accepted narrative is that the point spread was invented in the 1940s by math teacher and bookmaker Charles K. McNeil. He came up with the idea for the point spread as a way to offer bettors an even playing field when wagering on unevenly matched competitions, like in pro football. This allowed gamblers to bet on lopsided games while giving the underdog team an advantage via the spread handicap.

The Moneyline – Believed to emerge around the same era as the point spread, the moneyline is the simpler bet of picking a winner straight-up with no handicapping margin involved. With major professional sports leagues like the NFL forming in the mid-20th century, gamblers wanted a way to just wager on winners and underdogs without any points involved. Thus the moneyline was born as the fixed odds bet on picking a game’s victor.

Now that we’ve looked back at the beginnings of each betting method, let’s examine how they work in detail.

How Point Spread Betting Works

The point spread, as we touched on earlier, provides a handicap margin to make a contest more even between two mismatched opponents. Let’s look at a real example to better understand it in practice:

New England Patriots -7 (-110) vs. New York Jets +7 (-110)

In this matchup, the Patriots are 7-point favorites over the underdog Jets. New England must win the game by more than 7 points to “cover the spread.” If you bet on them at -7, they need to prevail by 8+ for your wager to cash.

The Jets, as 7-point underdogs, must either win the game outright or lose by 6 or fewer points. If you bet on them +7, they need to keep the final margin to -6 or better.

You’ll also notice the -110 odds on both sides. This means you would need to bet $110 to profit $100 if your team covers the spread. This vigorish, or “juice,” is how sportsbooks make their margin.

Now let’s look at a couple more examples to solidify understanding:

• Dallas Cowboys -3 (-105) vs. Philadelphia Eagles +3 (-115)

Here Dallas is favored by 3 points with slightly reduced -105 juice, while Philly is getting 3 points with higher -115 juice. For your Cowboys bet to cash, they’d need to win by more than 3. The Eagles would need to win outright or lose by 2 or less.

• Los Angeles Lakers -12.5 (-110) vs. Atlanta Hawks +12.5 (-110)

In the NBA, the spreads are usually much larger due to higher scoring and talent gaps. Here the Lakers have to prevail by 13+ as 12.5-point favorites. The Hawks need to lose by 12 or fewer as 12.5-point dogs.

As you can see, the spread provides a handicapped margin that makes betting competitive between two unevenly skilled teams. Now let’s examine how a moneyline bet works in contrast.

How Moneyline Betting Works

With a moneyline wager, you are simply betting on a game’s winner with no point spread involved. This looks something like:

Kansas City Chiefs -250 vs. Denver Broncos +195

The Chiefs are favorites priced at -250, meaning a $250 bet would profit $100 if they win. The Broncos are +195 underdogs, meaning a $100 wager would return $195 in profit with an upset victory.

These fixed moneyline odds are based on each team’s perceived chance of winning the game outright. Favorites are priced with minus odds, while bigger underdogs get higher plus odds.

Some more moneyline examples:

• Tampa Bay Lightning -180 vs. Florida Panthers +155

Here the Lightning are moderate -180 favorites to beat the Panthers straight up. Florida sits at +155 underdog odds.

• Oklahoma City Thunder +375 vs. Milwaukee Bucks -500

In the NBA markets with high scoring and talent gaps, moneyline odds can be very wide. OKC are major underdogs at +375 against the powerful Bucks at -500.

As you can see, the moneyline removes any handicapping margin and just offers fixed odds on each team to win. With the basics of each betting type explained, let’s compare some key differences.

7 Key Differences Between Spreads and Moneylines

Now that you understand the basics of point spreads versus moneylines, I want to highlight the most crucial differences to note:

1. Spreads allow betting on mismatches – The point spread enables action on lopsided matchups by handicapping the favorites and spotting points to the underdogs.

2. Moneyline focuses solely on the winner – With no spread, the moneyline eliminates any margin and comes down to picking the straight-up winner.

3. Spread odds tend to be consistent – Most spreads have standard -110 juice on each team. Moneyline odds fluctuate more.

4. Moneyline offers bigger underdog payouts – While less likely to win, huge underdogs bring exponentially bigger profits.

5. Spread betting has a “middle” – When the margin lands exactly on the spread number, it’s a push.

6. Buying points affects spreads – You can buy extra points on the spread for better odds if needed.

7. Teasers adjust spreads and odds – Teaser “parlays” allow adjusting spreads for lower odds.

As you can see, there are some very distinct differences to note that dictates when you may want to use one over the other. Now let’s do a case study to bring these concepts together.

Case Study: 2022 Super Bowl Spread vs. Moneyline Analysis

Let’s take an in-depth look at the most recent Super Bowl between the Rams and Bengals to see how their spread and moneyline odds compared:

The Rams entered as 4-point favorites with standard -110 juice on each side of the spread. On the moneyline, Los Angeles was priced at -200, while Cincinnati held +165 underdog odds.

Spread Betting Analysis – With the short 4-point spread, this lined up as an expected close game that could come down to a late field goal. The -110 odds on both sides made it appealing to bet the spread in either direction.

Moneyline Betting Analysis – The moneyline odds implied the Rams had around a 67% chance to win, while the Bengals were given approximately a 38% shot as underdogs. The +165 odds on Cincinnati were tempting for bettors sensing a potential upset.

In the end, the underdog Bengals covered the +4 spread in a tight 23-20 loss. The Rams did prevail on the moneyline, making them the winning straight-up wager as minor -200 favorites.

This illustrates how spreads and moneylines can offer different betting perspectives on the same game. Now as your final lesson, let’s discuss some strategies for when to use each.

Deciding Between Spread and Moneyline Bets

Based on the differences we’ve covered, here are some guidelines on when spread and moneyline wagers may be advantageous:

When Spread Bets Work Best

• Big mismatches where you want to spot points
• Extremely even contests where the margin is a toss-up
• Getting key numbers like 3 or 7 that often determine winners
• Teaser bets that allow adjusting the spread as needed

When Moneyline Bets Work Best

• Toss-up matchups where upsets are very possible
• Maximizing underdog value when you predict the upset
• Heavy favorites expected to dominate the game
• Parlaying multiple moneyline wagers together

As you gain experience, you’ll get more familiar with utilizing both spreads and moneylines to maximize profits across a range of situations.

Bottom Line

While spreads and moneylines involve picking a game winner, they operate very differently in terms of odds and payouts. I hope this detailed beginner’s guide has helped explain everything you need to know about spread versus moneyline betting.
