NFL Bet Line
An NFL bet line is three numbers, and each one costs you money if you misread it. Learn what every format means and you'll never guess at your payout again.
What Are American Odds — and Why Do They Use Plus and Minus Signs?
American odds are the default format at every legal US sportsbook. The minus sign marks the favorite; the plus sign marks the underdog. Simple as that. The number itself tells you the dollar stakes.
A minus number shows how much you must risk to profit $100. A line of -200 means you bet $200 to win $100 back. A plus number shows how much you win on a $100 stake. A line of +175 means a $100 bet returns $175 in profit.
Most NFL spread bets are priced at -110 on both sides. Bet $110, win $100. That extra $10 is the sportsbook's commission — the vig. For the full story on how that cut compounds over a season, read what vig is in NFL betting and how much the sportsbook takes.
How Do You Convert American Odds to Decimal?
Decimal odds include your original stake in the return. The math for -110 American: divide 100 by 110, then add 1. That gives you approximately 1.91. Bet $100, collect $191 total — $100 stake back plus $91 profit.
For plus odds the conversion is easier: divide the American number by 100, then add 1. So +175 becomes 2.75. Bet $100, collect $275.
| American Odds | Decimal Equivalent | Profit on $100 Stake | Role |
|---|---|---|---|
| -110 | 1.91 | $90.91 | Standard spread price |
| -200 | 1.50 | $50.00 | Heavy favorite moneyline |
| +175 | 2.75 | $175.00 | Underdog moneyline |
What Does -3.5 Mean on a Spread Line?
The spread is a scoring handicap baked into the line. If a team is -3.5, they must win by 4 or more for your spread bet to cash. The underdog at +3.5 can lose by 3 and still cover. That half-point — called the hook — eliminates any chance of a push.
When there's no hook and the final score lands exactly on the number, the bet is a push and your stake is refunded. Pushes get complicated in parlays. NFL parlay betting explained covers exactly what happens to your ticket when one leg pushes.

When Do You See PK Instead of a Number?
PK stands for pick 'em. The spread is zero; neither side is favored. Both teams are typically priced at -110. You're just picking the winner. It shows up more often than you'd think in evenly matched divisional games.
How Do These Odds Shift During the Week?
Sportsbooks release opening lines for Sunday games on Tuesday. As money pours in on one side, the line moves to balance the book. A spread might open at -3 and close at -4.5. Timing your bet matters. How NFL betting lines move during the week explains the mechanics behind those shifts.
