Football brings in more betting handle than any other sport in the US. The NFL regular season presents a schedule of betting opportunities that make the league a unique venture for sports bettors.
Starting with the season’s opening weekend, the NFL plays through a 17-week regular-season schedule each year. Each team plays 16 games with one bye week, and every weekend offers anywhere from 12-16 games open for betting.
The NFL season always brings plenty of surprises, and a team that might seem like a great pick early in the season often ends up as a weekly underdog later in the year.

How NFL Regular Season Odds Are Calculated
The most popular ways to bet on the NFL include moneyline, point spread, and totals betting. Online sportsbooks offer several other ways to bet on NFL games, but it’s important to understand the way fundamental football betting works.
For example, here’s a look at the odds on the Week 13 matchup between the Buffalo Bills and San Francisco 49ers from the 2020 NFL regular season. The lines on that game from DraftKings Sportsbook looked like this right before kickoff:
| Point Spread | Totals | Moneyline | |
|---|---|---|---|
| Buffalo Bills | +1.5 (-110) | Over 48 (-110) | +106 |
| San Francisco 49ers | -1.5 (-110) | Under 48 (-110) | -121 |
Point Spread
The point spread listed for an NFL game adds points to the underdog’s final score, or subtracts from the favorite’s final point total.
In the example above, the 49ers stand as a 1.5-point favorite over the Bills. For betting purposes, 1.5 points will be added to Buffalo’s score at the end of the game.
If San Francisco wins 31-30, for example, Bills bettors would win the wager. Buffalo would finish with 31.5 points to the 49ers 31 points.
Totals
Totals bets simply task the bettor with picking whether the final score will end up under or over the listed point total. For instance, the 31-30 San Francisco win we’ve talked about above would result in a win for Over 48 at DraftKings Sportsbook.
Moneyline
Moneyline bets represent a straight-up wager on what team will win the game, with no point spread involved. Winning bets on the underdog pay off at better odds than the favorite, and a big NFL upset can lead to a big payout on the underdog.
Calculating American Odds
How Are Horse Betting Odds Calculated
Note that all of the lines on the Bills-49ers games offer payout odds listed in American Odds. The -110 seen on both sides of the points spread and totals line represents a bet that pays -110 American Odds.
To calculate “-“ American Odds, divide 100 by the odds number (without the minus sign) and multiply that quotient by the amount wagered.
For example, a $50 bet that pays -110 odds would calculate as (100/110)*$50, which converts to (.909*$50) and then to $45.45. A $50 winning bet on -110 odds would return $95.45 total to the bettor ($45.45 profit plus the original $50 bet).
Calculating “+” odds, like the +106 payout on the Bills moneyline bet, involves a slightly different formula. “+” payouts are calculated by dividing the odds number by 100, then multiplying by the amount wagered to determine the profit.
A $50 bet on the +106 line for Buffalo would solve as (110/100)*$50, which calculates to (1.1*$50) and then to $55.
A $50 winning wager at +106 odds would return $105 total to the bettor ($55 profit plus the original $50 bet).
What Causes Point Spread And Moneyline Odds To Change During The Week?
Suppose the Bills-49ers game showed the 49ers as a -4 favorite at DraftKings Sportsbook a week before the game, but by game day the line showed the -1.5 point spread listed above.
The lines on an NFL game can change as the week goes on, sometimes shifting dramatically. Changes can occur right up until kickoff.
If a sportsbook gets too many bets on one side of a line, the book stands to lose big if that side wins. To combat this, sportsbooks will shift the point spread and moneyline odds one way or another, in an effort to get the right amount of money (from the sportsbook’s money-making perspective) on each side of the game.
