AI Summary
American Odds: The Plus and Minus
American odds tell you two things at once: who the favorite is, and what a bet returns. It all comes down to the plus (+) and minus (-) sign.
- A minus number marks the favorite. It shows how much you need to stake to profit $100. Example: -150 means you stake $150 to make a $100 profit.
- A plus number marks the underdog. It shows how much profit you make on a $100 stake. Example: +130 means a $100 stake returns $130 profit.
You do not have to bet in round hundreds. The odds simply scale. A $10 bet at +130 returns $13 profit, plus your stake back.
The bigger the minus number, the heavier the favorite. The bigger the plus number, the longer the underdog, and the more a correct call pays.
Reading the Moneyline
The moneyline is the simplest market: pick the winner, ignore the margin.
Say the Chiefs are -150 and the Bengals are +130. Back the Chiefs, and they just need to win, straight up. Back the Bengals, and you get a bigger return because they are the underdog. That is the trade-off every bettor weighs: a safer favorite for a smaller payout, or a riskier dog for a bigger one.
Reading the Point Spread
The spread levels the field by giving the underdog a head start. It is the most popular way to bet on NFL games.
Example: Chiefs -3.5, Bengals +3.5.
- Back the Chiefs -3.5, and they must win by 4 or more points to cover.
- Back the Bengals +3.5, and they can lose by 3 or fewer, or win outright, and you are good.
The half-point (the "hook") removes ties. When a spread is a whole number like -3, and the result lands exactly on it, the bet is a push, and your stake is refunded.
You will usually see a price next to the spread, like -110. That is the standard juice, or vig, the small margin the sportsbook builds in. At -110, you stake $110 to profit $100.
Reading the Total (Over/Under)
The total is the combined score of both teams. The sportsbook sets a number, and you bet on whether the actual total goes over or under it.
Example: Over 48.5 (-110) / Under 48.5 (-110). If the final score is 49 or more, the Over hits. 48 or fewer, the Under hits. Simple as that, and it keeps you in the action no matter who comes out on top.
Decimal and Fractional Odds
Most US boards default to American odds, but you can switch formats at Voltage Bet if another style reads faster for you.
- Decimal odds show your total return per $1 staked, including the stake. -150 becomes 1.67, and +130 becomes 2.30. Multiply your stake by the number to see the full payout.
- Fractional odds show profit as a fraction of your stake. +130 becomes 13/10, meaning $13 profit for every $10 staked.
Same odds, three ways of writing them. Pick whichever one you decode quickest.
Turning Odds Into Probability
Odds are not just a payout guide. They are the sportsbook's read on how likely each outcome is. Convert them to implied probability, and you can judge whether a line offers value.
- For a favorite: minus odds / (minus odds + 100). So -150 = 150 / 250 = 60%.
- For an underdog: 100 / (plus odds + 100). So +130 = 100 / 230 = about 43%.
If you think a team's real chance of winning is higher than the implied probability, that is the kind of value bet worth chasing.
Putting It All Together
Here is a full NFL matchup as it might appear on the board:
- Chiefs: -3.5 (-110) spread | -150 moneyline | Over 48.5 (-110)
- Bengals: +3.5 (-110) spread | +130 moneyline | Under 48.5 (-110)
Read it left to right, and you have the spread, the moneyline, and the total for both teams. That is the entire game in a single line, and now you can decode every part of it.

- Watch line movement. If a spread drifts from -3 to -6, the market is telling you something.
- Shop for the best number. Half a point can decide a bet, so grab the sharpest line available.
- Respect the juice. That -110 adds up over time, so factor it into every play.
- Trust the probability, not the payout. A long price is only worth it when the chance is really there.
Knowing how to read NFL odds turns a wall of numbers into a clear picture of risk, reward, and value. That is the edge every smart bettor starts with. Better still, the same plus-minus logic reads identically across every market we run, from esports to horse racing.
