NFL over/under totals: how to research the number
By DeepChamp research team · Updated · Methods and limitations
Short answer
An NFL total is an over/under on the combined points both teams score in a game, overtime included. To research it, estimate how many possessions each offense will get and how often those drives finish with touchdowns instead of field goals, then check the weather and who is available. Compare your range with the posted number and price.
What it is and how it settles
A game total sets a combined-points number, such as 44.5, and the over or under settles on both teams' scores added together. Overtime counts in standard markets, and defensive and special-teams touchdowns count because they add to the score. Whole-number totals can land exactly and return the stake as a push. A game that is suspended or not completed is handled under the operator's rules, so read them.
Settlement rules to check
- Overtime points are included in standard totals, but confirm the wording, especially for alternate or half-game versions.
- Whole-number totals can push; half-point totals cannot.
- Totals count every point scored, including extra points, two-point conversions and defensive or special-teams scores.
- Suspended or shortened games are handled by the operator's rules and may be voided.
What moves NFL over/under totals
Possessions and pace
Points are possessions multiplied by points per possession. A slow offense that runs the clock and a defense that forces long drives reduce the count of possessions for both teams, which can matter more than the efficiency of either one.
Red-zone finishing
Field goals and touchdowns are worth different amounts. A team that moves between the twenties and settles for kicks scores differently from one that converts those trips, so study red-zone and goal-to-go outcomes, not only yardage.
Turnovers and field position
Short fields created by turnovers and special teams produce points with few yards. Strong coverage units and returners shift expected points, but turnovers are volatile, so avoid projecting a recent streak forward.
Weather and roof
Wind is usually the weather factor that matters most for scoring, because it hurts passing and kicking. Heavy rain or snow can also cut points, and a dome removes the question, so the same teams can have different totals indoors and outdoors.
Injuries and personnel
A missing quarterback, tackle or top receiver changes both scoring and the clock. A hurt pass rusher or cornerback can raise the total, so look at both sides of the ball before deciding which team is affected.
Clock use and the lead
A team with a lead runs the ball and uses the clock, which cuts possessions for both sides. That is why a big favorite can lower the combined points of a game even when the favorite itself scores freely.
How to research it, step by step
- 1Split the total into two team totals using the spread, then judge each side's expected points on its own.
- 2Estimate how many possessions each offense will have by looking at pace, run rate and time of possession.
- 3Compare each team's touchdown conversion in the red zone with its field goal frequency to see how drives usually end.
- 4Check the forecast for wind, precipitation and temperature near kickoff, and confirm whether the stadium has a roof.
- 5Review injuries for quarterbacks, offensive linemen and defensive playmakers on both sides, since either can move the number.
- 6Compare your range with the line on each side, and think about how a single overtime period would change the result.
Worked example: the number and the price
A hypothetical outdoor game has a total of 41.5, with the under priced at -120 and the over at +100. A hypothetical forecast calls for steady wind, which supports a lower-scoring view in your own estimate.
| Under 41.5 points at -120 | 54.5%break-even probability |
|---|---|
| Over 41.5 points at +100 | 50.0%break-even probability |
| Both sides added together | 104.5%a margin of 4.3% of the market |
| No-vig probability for Under 41.5 points | 52.2%fair price about -109 |
| Your hypothetical estimate | 57.0%+2.5 points against break-even |
| Expected value on a 100 stake | $4.50only if the estimate were exactly right |
Weather is the reason for the estimate, and weather is the input most likely to change before kickoff. If the forecast softens, the case for the under weakens, and a price that looked fair at the start may no longer match your view.

Common mistakes
Treating the over as the exciting side
Researching only the reasons for more points leaves out the way a lead slows a game. Write the case for the under before judging the number.
Borrowing last week's score
One high-scoring game can come from turnovers and short fields instead of pace. Look at what drove the score before assuming it repeats.
Trusting an early forecast
A forecast made days ahead can change, and the wind at kickoff decides its effect. Re-check shortly before the game, and note whether the stadium is open or closed.
Common questions
Does overtime count toward an NFL game total?
In standard totals markets, yes: overtime points are part of the final score. A few versions are written for regulation time only, so confirm the wording, particularly on alternate or half-game totals.
How does wind affect an NFL over/under?
Strong wind makes deep passes and long field goals harder, which can reduce scoring and bring more punts and conservative play. Gusts matter more than a light breeze, so read the forecast and how exposed the stadium is.
How do I turn an NFL spread and total into expected team scores?
The favorite's expected score is half of the total plus half of the spread, and the underdog's is half of the total minus half of the spread. It is a rough picture of the market's view, not a forecast.
What is a push on an NFL total?
A push happens when the combined score lands exactly on a whole-number total, and the stake is returned. Half-point totals cannot push. Alternate totals may be priced differently, so read the number and price carefully.
