When you open a sports betting site for the first time, you're hit with an avalanche of terms: Moneyline, Spread, Over/Under, Totals, Handicap... Enough to get lost quickly.
Yet the reality is simple: 95% of sports bets come down to three types. Once you master them, everything else is just a variation.
In this guide, we'll break down each of these three fundamental bets with real-world examples, payout calculations, and sport-specific advice. You'll learn not just how they work, but most importantly when to use each one depending on the sport and situation.
The 3 Bet Types at a Glance
| Bet Type | Question Asked | Example | Risk/Reward |
|---|---|---|---|
| Moneyline | Who will win? | Yankees at 1.65 vs Red Sox at 2.30 | Simple but low value on heavy favorites |
| Spread | Who wins with the handicap? | Chiefs -7 vs Bills +7 | Balanced odds, requires margin prediction |
| Totals | How many total points/goals? | Over/Under 6.5 goals | Ignores the winner, focuses on scoring |
Each type answers a different question. Understanding all three — and knowing when to deploy each one — is what separates recreational bettors from analytical ones.
1. Moneyline: The Simplest Bet
How It Works
Moneyline is the most intuitive bet: you bet on the match winner. No points, no handicap, no complications.
NHL Example: - Montreal Canadiens: 2.40 - Toronto Maple Leafs: 1.58
If you bet $10 on Montreal and they win, you get back $24 ($10 x 2.40). If you bet $10 on Toronto and they win, you get back $15.80 ($10 x 1.58).
Payout Calculation: Step by Step
Payout = Stake x Decimal Odds
Profit = Payout - Stake
Example: $50 bet on the Canadiens at 2.40
Payout = $50 x 2.40 = $120
Profit = $120 - $50 = $70
For American odds (common in the US):
Positive odds (+150):
Profit = Stake x (Odds / 100)
$50 x (150 / 100) = $75 profit
Negative odds (-180):
Profit = Stake x (100 / |Odds|)
$50 x (100 / 180) = $27.78 profit
For more on how odds formats relate to each other, read our guide on converting American, decimal, and fractional odds.
What the Odds Tell You
A decimal odd represents an implied probability:
Implied Probability = 1 / Decimal Odds x 100
Toronto: 1 / 1.58 x 100 = 63.3%
Montreal: 1 / 2.40 x 100 = 41.7%
Combined: 63.3% + 41.7% = 105%
The total exceeds 100% because of the bookmaker's margin — the "juice" or "vig." That extra 5% is how sportsbooks guarantee profit. We explain this thoroughly in our guide on how bookmakers make money.
Real-World Moneyline Scenarios
| Scenario | Odds | $100 Bet Profit | Implied Prob | Break-Even WR |
|---|---|---|---|---|
| Heavy favorite | 1.25 | $25 | 80% | 80% |
| Slight favorite | 1.65 | $65 | 60.6% | 60.6% |
| Underdog | 2.80 | $180 | 35.7% | 35.7% |
| Big underdog | 5.00 | $400 | 20% | 20% |
The "Break-Even WR" column is key. This is where the concept of value betting becomes essential — you're looking for spots where your estimated win probability exceeds the break-even threshold.
When to Use Moneyline
Ideal for: - Close matchups where you have a strong conviction - Hockey (NHL) where scores are often tight and upsets happen frequently - Baseball (MLB) where there are no draws and the run line is often too rigid - Soccer underdogs — the 3-way moneyline (1X2) provides value on home/draw/away
Avoid when: - A heavy favorite has an extremely low price (1.15, 1.20) — one upset erases five wins - The sport features large scoring margins (NBA, NFL) — spreads are usually better
The Problem with Very Low Odds
Betting on a favorite at 1.20 means risking $100 to win $20. A single upset erases 5 winning bets.
Scenario: Betting 1.20 favorites
Win 5 bets: +$20 x 5 = +$100
Lose 1 bet: -$100
Net after 6 bets: $0
You need an 83.3% win rate just to break even!
Golden rule: If the Moneyline odds are below 1.40, look at the Spread instead.

2. Spread: Leveling the Playing Field
How It Works
The Spread (or handicap) is the bookmaker's solution when two teams are at very different levels. Instead of betting on "who wins," you bet on "who wins with the handicap applied."
NFL Example: - Kansas City Chiefs: -7 (odds 1.91) - Buffalo Bills: +7 (odds 1.91)
- Chiefs -7: The Chiefs must win by more than 7 points for your bet to win
- Bills +7: The Bills can lose by fewer than 7 points (or win outright) for your bet to win
Think of it this way: the bookmaker is "giving" the Bills a 7-point head start.
Concrete Examples
Example 1 — Close game (Chiefs 27, Bills 23):
Margin of victory: 27 - 23 = 4 points
Spread: Chiefs -7
Adjusted score: Chiefs (27-7) = 20, Bills 23
Result: Bills +7 WINS, Chiefs -7 LOSES
Example 2 — Blowout (Chiefs 31, Bills 20):
Margin of victory: 31 - 20 = 11 points
11 > 7, so Chiefs "cover" the spread
Result: Chiefs -7 WINS, Bills +7 LOSES
Example 3 — NBA (Celtics 118, Wizards 108):
Line: Celtics -8.5 vs Wizards +8.5
Margin: 118 - 108 = 10 > 8.5
Result: Celtics -8.5 WINS
Notice the half-point (8.5) — this eliminates the possibility of a "push."
The "Push": When Nobody Wins
If the Chiefs win by exactly 7 points (e.g., 28-21), it's a push. Your stake is refunded — no win, no loss. That's why you'll often see half-point spreads: -7.5 or +6.5.
Spread Payout Calculation
Both sides are typically priced around 1.91 (or -110 in American format):
$100 bet on Chiefs -7 at 1.91:
If Chiefs cover: Payout = $191 (profit: $91)
If Chiefs don't cover: Loss = $100
If push: $100 returned
The bookmaker's margin is embedded: instead of 2.00 (true 50/50), you get 1.91. To minimize this cost, check out our guide on line shopping.
When odds shift away from 1.91, it signals money is coming in on one side. Tracking these line movements can reveal where sharp bettors are active.
Key Numbers in the NFL
Certain spreads are more frequent due to the scoring system:
| Spread | Why It Matters | Frequency |
|---|---|---|
| 3 | One field goal difference — most common margin | ~15% of games |
| 7 | One touchdown difference | ~9% of games |
| 6 | TD without extra point or two FGs | ~5% of games |
| 10 | TD + FG | ~4% of games |
| 14 | Two touchdowns | ~3% of games |
Betting on -3 or -7 carries more push risk. For a deep dive, see our guide on key numbers in the NFL.
NBA Spread Specifics
NBA spreads differ from NFL:
- Higher numbers: commonly 1 to 15+ points
- More variance: a team can erase a 15-point deficit in minutes
- Garbage time: bench players in blowouts dramatically affect the spread
Example: Lakers -6.5 vs Hornets +6.5
Lakers lead by 20 with 3 minutes left, rest starters.
Hornets' bench scores 10 quick points.
Final: Lakers win by 8.
Lakers -6.5 still covers, but -12.5 wouldn't have.
NBA spreads require analysis of team depth, pace of play, and rest situations.
When to Use Spread
Ideal for: - American football (NFL, NCAA) — the sport where spreads dominate - Basketball (NBA) — high scores create meaningful handicap markets - When a favorite is too expensive on the Moneyline
Avoid when: - Hockey (NHL) — scores too tight, puck line locked at +/-1.5 - Baseball (MLB) — the run line is rigid - Soccer — use Asian Handicap instead
3. Totals (Over/Under): Betting on the Combined Score
How It Works
With Totals, you don't care about who wins. You're betting on the total number of points/goals/runs scored by both teams combined.
NHL Example: - Over 6.0: 1.87 - Under 6.0: 1.95
- Over 6.0: 7 or more goals in the game
- Under 6.0: 5 or fewer goals
If the final score is 4-2 (6 total), it's a push — stake refunded.
Totals Payout Calculation
$75 on Over 6.0 at 1.87 — Final: 4-3 (7 goals)
Payout = $75 x 1.87 = $140.25 | Profit = $65.25
$75 on Under 6.0 at 1.95 — Final: 2-1 (3 goals)
Payout = $75 x 1.95 = $146.25 | Profit = $71.25
Why It's the Pros' Favorite Bet
Totals have a major advantage: you don't need to guess the winner. Predicting the scoring environment relies on stable, measurable data — pitching quality, pace of play, defensive efficiency, and weather. This is often more predictable than guessing who will win.
At ProbWin, our Totals models consistently outperform our winner-prediction models. Check our verified results to see each market's performance.
Factors That Influence Totals
For baseball (MLB): - Starting pitcher quality (xERA is more predictive than ERA) - Park factors (Coors Field vs. Oracle Park) - Weather (wind out = more HRs) and bullpen quality
For hockey (NHL): - Starting goalies (GSAx) - Corsi and expected goals - Back-to-back fatigue and special teams
For football (NFL): - Weather (rain, wind, cold reduce scoring significantly) - Offensive style and defensive EPA
For basketball (NBA): - Pace (possessions per 48 minutes) - Rest days and injuries

Over vs Under: Which to Choose?
The public tends to bet Over — it's more exciting to see points scored. Bookmakers know this and sometimes adjust lines accordingly, creating opportunities on the Under.
| Signal | Leans Over | Leans Under |
|---|---|---|
| Pace / tempo | Both teams play fast | One or both play slow |
| Pitching / goaltending | Weak starters | Elite starters |
| Weather | Warm, no wind | Cold, rain, strong wind |
| Injuries | Defensive players out | Offensive stars out |
| Recent form | Both scoring above average | Scoring drought |
Partial Game Totals
| Market | Description | Why It's Useful |
|---|---|---|
| First 5 Innings (F5) | First 5 innings total (MLB) | Isolates starting pitchers |
| 1st Period | First period total (NHL) | Teams play most structured early |
| 1st Half | First half total (NFL, NBA) | Removes garbage time |
| Team Totals | One team's scoring only | When you're confident about one side |
In MLB, F5 Totals depend primarily on starting pitchers — the bullpen doesn't factor in. This is where ProbWin achieves some of its best results.

Which Bet Type for Which Sport?
Each sport has a "natural" bet type — the market where the most liquidity flows and where analytical bettors find the most value.
| Sport | Primary Market | Secondary Market | Why | Avoid |
|---|---|---|---|---|
| NFL | Spread | Totals | Large margins (TDs worth 7 pts), key numbers create angles | ML on favorites |
| NBA | Totals + Spread | ML (close games) | High scoring, pace/efficiency are highly measurable | ML on heavy favorites |
| NHL | Moneyline | Totals | Low scoring (~6 goals avg), puck line too rigid at +/-1.5 | Puck Line (usually) |
| MLB | ML + Totals | F5 Totals | One pitcher has outsized impact, run line too rigid | Run Line (usually) |
| Soccer | O/U 2.5, BTTS | Asian Handicap, 1X2 | Draws happen ~25%, BTTS is unique to soccer | Parlays with 1X2 |
| Tennis | Moneyline | Total Games | Two-player sport, sets create natural ML market | Set betting (high variance) |
Key takeaway: NFL and NBA are spread sports. NHL and MLB are moneyline sports. Totals offer excellent value in every sport. For tennis, see our tennis betting markets guide.

Common Beginner Mistakes by Bet Type
Avoiding these pitfalls will immediately improve your results. For a comprehensive list, see the 7 classic beginner betting mistakes.
Moneyline Mistakes
1. Chasing heavy favorites blindly
Odds of 1.30 imply 77% win rate. If the team only wins 73% of the time, you're losing money long-term — even though most bets cash.
EV at 1.30 with 73% true probability:
EV = (0.73 x $30) - (0.27 x $100) = -$5.10 per $100 bet
You WIN most bets but LOSE money over time.
2. Ignoring the draw in soccer
In 1X2 markets, the draw siphons probability from both sides. Treating soccer moneyline like a two-outcome market leads to overestimating win chances.
3. Not comparing odds across books
A moneyline of 2.10 vs 2.25 at another book is a 7% difference in profit. Always shop for the best line.
Spread Mistakes
1. Forgetting key numbers (NFL)
Many NFL games are decided by exactly 3 points (field goal). Getting -2.5 instead of -3 can be the difference between winning and pushing.
2. Ignoring garbage time (NBA)
Teams leading by 20 rest starters in Q4. The trailing team's bench scores meaningless points — the dreaded "backdoor cover."
3. Treating the spread as a prediction
The spread isn't the bookmaker's prediction of the margin. It's the number designed to attract equal action on both sides.
Totals Mistakes
1. Following the public on Overs
The public loves excitement (= Over). Bookmakers know it. Don't bet Over without quantifying your estimate against the posted line.
2. Ignoring the weather (NFL/MLB)
A 20 mph wind or heavy rain can suppress NFL scoring by 5+ points. Always check weather for outdoor totals.
3. Using season averages without context
Bad analysis:
Team A avg: 110 PPG + Team B avg: 105 PPG = 215
"The total is 220, so Under"
Better analysis:
- Team A's pace ranks 5th (fast)
- Team B's defense ranks 28th (bad)
- Team A's starting PG just returned
- Last 5 H2H averaged 228 points
-> The Over at 220 has value
Side-by-Side Comparison
| Feature | Moneyline | Spread | Totals |
|---|---|---|---|
| Complexity | Very simple | Moderate | Moderate |
| Need to pick winner? | Yes | Yes (with margin) | No |
| Typical odds range | 1.20 - 5.00+ | 1.87 - 1.95 | 1.80 - 2.00 |
| Best for favorites? | No (poor value) | Yes | N/A |
| Best for underdogs? | Yes | Yes | N/A |
| Data requirements | Team strength | Strength + margin | Scoring environment |
| Public bias | Favorites | Favorites | Overs |
| Pro edge | Underdogs, close games | Key numbers | Weather, matchups |
Parlays and Teasers: A Quick Note
Parlays combine multiple bets — all must win. Payouts multiply but so does risk:
Chiefs -7 (1.91) + Over 48.5 (1.87) + Lakers ML (1.55)
Combined odds: 1.91 x 1.87 x 1.55 = 5.54
$20 bet = $110.80 payout — but ALL THREE must hit.
Teasers (NFL/NBA) let you adjust spreads in your favor. See our NFL teasers guide.
Beginner advice: Stick to straight bets. Parlays are entertaining but mathematically inferior for long-term profit.
Frequently Asked Questions
What is the easiest bet type for beginners?
Moneyline is the simplest to understand — you just pick the winner. However, "easiest to understand" doesn't mean "easiest to profit from." Many beginners gravitate toward heavy favorites, which is one of the worst long-term strategies. For a balanced start, try Totals — the underlying data (pace, pitching, weather) is more concrete and measurable.
Can I bet Moneyline, Spread, and Totals on the same game?
Yes. These are independent markets that settle separately. Be careful about correlated risk: betting a team's spread AND the over means a blowout covers both while a close low-scoring game loses both. Good bankroll management prevents overexposure.
What does "covering the spread" mean?
When a team "covers," it means they beat the handicap. If the Lakers are -6.5 and win by 10, they covered. If they win by 5, they didn't cover — even though they won the game outright. This distinction is a common source of frustration for beginners.
Why do Totals lines have half-points (like 6.5)?
Half-points eliminate pushes. With a total of 6.5, the result is always Over or Under — never a refund. When you see whole numbers (like 6.0), a push is possible if the combined score lands exactly there.
How do I know which bet type offers the best value?
Compare your estimated probability to the implied probability of the odds. The market where you find the biggest gap is where you have the most value. If you think the Packers will win by 10+ but the spread is only -3.5, the spread offers more value than the moneyline. ProbWin automates this comparison — see how our system finds value.
Conclusion: Master the Basics Before Going Further
You now know the three pillars of sports betting:
- Moneyline: Simple, direct — who will win?
- Spread: Levels the field — by how much will they win?
- Totals: Ignores the winner — how many total points?
The choice depends on the sport, the game, and your analysis. A good bettor uses whichever type offers the best opportunity. In the NFL, that's usually the spread. In the NHL, it's the moneyline. In every sport, totals offer data-driven opportunities that many bettors overlook.
Your next steps:
- Convert different odds formats so you can compare prices anywhere
- Understand how bookmakers calculate odds and where their margin hides
- Master value betting — the single most important concept for profitability
- Set up bankroll management before placing real money bets
- Learn line shopping to always get the best available price
The goal isn't to "guess" the right bet. It's to identify situations where the bookmaker has mispriced the probabilities — the famous value bets. That's exactly what ProbWin does every day, with public and verifiable results.
