Sports Moneyline Calculator: Odds & Payouts Guide (2026)
Sports Moneyline Calculator: Convert Odds Instantly
Moneyline bets are the purest form of sports betting—pick the winner. Our calculator converts American odds to payouts instantly, shows implied probability, and helps you identify value in any matchup.
What Is a Moneyline Bet?
A moneyline bet wagers on which team/player wins outright—no point spread involved. Odds indicate both payout and implied probability.
Quick Answer: Positive odds (+150) show profit on a $100 bet ($150 profit). Negative odds (-150) show how much to bet for $100 profit (bet $150 to win $100). Convert to implied probability: -150 = 60% implied win rate, +150 = 40% implied win rate.

Understanding Moneyline Odds
Negative Odds (Favorites)
Negative odds show how much you must bet to win $100:
| Odds | Bet This | To Win | Implied Probability |
|---|---|---|---|
| -100 | $100 | $100 | 50% |
| -110 | $110 | $100 | 52.4% |
| -150 | $150 | $100 | 60% |
| -200 | $200 | $100 | 66.7% |
| -300 | $300 | $100 | 75% |
| -500 | $500 | $100 | 83.3% |
Positive Odds (Underdogs)
Positive odds show profit on a $100 bet:
| Odds | Bet | Profit | Implied Probability |
|---|---|---|---|
| +100 | $100 | $100 | 50% |
| +150 | $100 | $150 | 40% |
| +200 | $100 | $200 | 33.3% |
| +300 | $100 | $300 | 25% |
| +500 | $100 | $500 | 16.7% |
| +1000 | $100 | $1000 | 9.1% |
Moneyline Payout Formulas
For Negative Odds
Profit = (Bet × 100) / |Odds|
Total Payout = Bet + Profit
Example: $50 bet at -150
- Profit = ($50 × 100) / 150 = $33.33
- Total payout = $50 + $33.33 = $83.33
For Positive Odds
Profit = (Bet × Odds) / 100
Total Payout = Bet + Profit
Example: $50 bet at +150
- Profit = ($50 × 150) / 100 = $75
- Total payout = $50 + $75 = $125
Implied Probability
Calculating Implied Probability
For negative odds:
Implied % = |Odds| / (|Odds| + 100)
For positive odds:
Implied % = 100 / (Odds + 100)
Example Calculations
-150 odds:
150 / (150 + 100) = 150 / 250 = 60%
+150 odds:
100 / (150 + 100) = 100 / 250 = 40%
Why Probabilities Don't Add to 100%
A typical matchup: Team A -150, Team B +130
- Team A implied: 60%
- Team B implied: 43.5%
- Total: 103.5%
The difference (3.5%) is the "vig" or "juice"—the sportsbook's profit margin.
Real-World Moneyline Examples
Example 1: Heavy Favorite
Game: Lakers -300 vs. Hornets +240
$100 on Lakers:
- Profit if win: $33.33
- Total return: $133.33
- Implied probability: 75%
$100 on Hornets:
- Profit if win: $240
- Total return: $340
- Implied probability: 29.4%
Example 2: Close Matchup
Game: Bills -120 vs. Dolphins +100
$100 on Bills:
- Profit if win: $83.33
- Implied probability: 54.5%
$100 on Dolphins:
- Profit if win: $100
- Implied probability: 50%
Total implied: 104.5% (4.5% vig)
Example 3: Huge Underdog
Game: #1 Alabama -1500 vs. FCS Team +800
$100 on Alabama:
- Profit if win: $6.67
- Implied probability: 93.8%
$100 on FCS Team:
- Profit if win: $800
- Implied probability: 11.1%
Analysis: $6.67 profit on heavy favorite has poor risk/reward.
Finding Value in Moneylines
What Is Value?
Value exists when your estimated probability exceeds implied probability:
| Your Estimate | Implied Probability | Value |
|---|---|---|
| 55% | 50% | +5% value |
| 55% | 60% | -5% (no value) |
| 65% | 60% | +5% value |
Value Calculation
Edge = Your Probability - Implied Probability
Expected Value = Edge × Potential Profit - (1 - Your Probability) × Bet
Example:
- Your probability: 55%
- Odds: +110 (implied 47.6%)
- Edge: 55% - 47.6% = 7.4%
- This is a value bet
Moneyline vs. Point Spread
When to Bet Moneyline
| Situation | Moneyline Better |
|---|---|
| Close game, slight favorite | Often |
| Avoiding half-point risk | Sometimes |
| Heavy underdog (+200+) | Sometimes |
| Heavy favorite (-300+) | Rarely |
When Spread Is Better
| Situation | Spread Better |
|---|---|
| Heavy favorite (less risk) | Usually |
| Want even-money odds | Usually |
| Game decided by 1-3 points | Often |
Break-Even Calculation
At what point spread is moneyline equivalent?
-150 moneyline (60% implied): Need to win 60% to break even. If spread gives -110 both ways (52.4% break-even), spread may be better for favorites.
Common Moneyline Mistakes
1. Ignoring the Vig
Mistake: Assuming +150/-150 is fair Reality: Both sides paying juice Fix: Calculate true probabilities and vig
2. Chasing Heavy Favorites
Mistake: -500 "can't lose" Reality: One loss wipes five wins Fix: Consider risk/reward ratio
3. Ignoring Implied Probability
Mistake: Betting because "team is good" Reality: Price may already reflect that Fix: Compare your probability to implied
4. Small Sample Thinking
Mistake: "Heavy favorites always win" Reality: -300 loses 25% of the time Fix: Understand probability over many bets
Frequently Asked Questions
What does -110 mean?
Bet $110 to win $100. It's the standard line for point spreads, representing about 4.5% vig.
Why are some moneylines so high?
Heavy favorites (-500+) or underdogs (+500+) reflect extreme probability differences. The odds adjust to balance action.
Is betting favorites profitable?
Not inherently. You need to find odds where implied probability is lower than actual probability—this can happen with any line.
How do I convert to decimal odds?
- Negative: (100 / |odds|) + 1 → -150 = 1.67
- Positive: (odds / 100) + 1 → +150 = 2.50
What's a "pick 'em"?
When both teams are -110 or close to even money. Sportsbook sees it as a 50/50 game.
Should I ever bet huge favorites?
Rarely. -500 requires 5 wins to offset 1 loss. The risk/reward is usually unfavorable.
Moneyline Strategies
Underdog Hunting
Look for underdogs with higher win probability than implied:
- Teams with strong defense (low scoring games have variance)
- Divisional games (familiarity creates upsets)
- Back-to-back situations for favorites
Live Betting Moneylines
Moneylines shift dramatically during games:
- Trailing favorite may offer value
- Early underdog lead creates favorite value
- Watch for overreactions to single plays
Parlaying Moneylines
Combining favorites increases payout but multiplies risk:
- Two -200 favorites: +150 combined
- Risk: One loss kills entire parlay
- Generally: Avoid parlaying heavy favorites
