Formula: P(success) = 100 / (1 + e^(k(d - midpoint))) x SkillFactor - WindPenalty + TempAdj + IndoorBonus
Worked example — 57.2% success probability | 1.72 expected points | Decision: Attempt Field Goal
Formula
P(success) = 100 / (1 + e^(k(d - midpoint))) x SkillFactor - WindPenalty + TempAdj + IndoorBonus
The base probability uses a logistic regression model where d is distance in yards, k is a steepness factor (0.115), and midpoint is the 50% probability distance (47 yards). Adjustments are made for kicker skill relative to league average, wind speed and direction, temperature, and indoor/outdoor venue.
Worked Examples
Example 1: Standard 40-Yard Attempt
Problem:An 85% career-accuracy kicker attempts a 40-yard field goal outdoors with 10 mph crosswind at 55 degrees Fahrenheit.
Solution:Base probability at 40 yards: 100 / (1 + e^(0.115 x (40-47))) = 69.2% Skill factor: 85/85 = 1.0x Crosswind penalty: 10 mph x 1.2 = 12.0 percentage points Temperature adjustment: 55F = no adjustment Adjusted probability: 69.2% x 1.0 - 12.0 = 57.2% Expected points: 0.572 x 3 = 1.72 points
Result:57.2% success probability | 1.72 expected points | Decision: Attempt Field Goal
Example 2: Long-Distance Indoor Attempt
Problem:A 90% career-accuracy kicker attempts a 55-yard field goal in a dome (no wind, 72F).
Solution:Base probability at 55 yards: 100 / (1 + e^(0.115 x (55-47))) = 28.6% Skill factor: 90/85 = 1.059x No wind penalty (indoor) No temperature adjustment (72F) Indoor bonus: +5% Adjusted probability: 28.6% x 1.059 + 5 = 35.3% Expected points: 0.353 x 3 = 1.06 points
Result:35.3% success probability | 1.06 expected points | Decision: Consider game situation carefully
Frequently Asked Questions
How is field goal probability calculated based on distance?
Field goal probability follows a logistic (sigmoid) curve that decreases as distance increases. NFL historical data shows that kickers make approximately 95 percent of attempts from 20 to 29 yards, 87 percent from 30 to 39 yards, 80 percent from 40 to 49 yards, and roughly 65 percent from 50 to 59 yards. Beyond 60 yards, the success rate drops below 30 percent. Football Field Goal Probability Calculator uses a logistic regression model fitted to these historical success rates, with the inflection point near 47 yards where probability crosses 50 percent for an average kicker. The sigmoid shape reflects the physical reality that each additional yard of distance requires exponentially more precise leg speed, angle, and timing.
How does wind affect field goal accuracy in the NFL?
Wind is one of the most significant environmental factors affecting field goal success. A headwind directly opposes the ball flight path, requiring the kicker to generate more power which often compromises accuracy, reducing success rates by approximately 1.5 to 2 percentage points per mile per hour of headwind. Crosswinds push the ball laterally, requiring the kicker to aim off-center and trust the wind to carry the ball back, reducing accuracy by roughly 1 to 1.5 percentage points per mph. Tailwinds provide a slight benefit of about 0.5 percentage points per mph by extending the ball carry distance. Wind gusts are especially problematic because inconsistent wind makes trajectory prediction nearly impossible for kickers adjusting their aim and power.
Does cold weather really make field goals harder to kick?
Cold weather significantly impacts field goal kicking through multiple mechanisms. Football air pressure drops in cold conditions per the ideal gas law, making the ball slightly softer and reducing the energy transfer from foot to ball, which can cost several yards of distance. Freezing temperatures below 32 degrees Fahrenheit can reduce kick distance by 3 to 5 yards compared to moderate conditions. Cold muscles are less elastic and generate less power, increasing injury risk and reducing kicking performance. Frozen or hard turf also affects footing stability during the plant step. NFL data shows that field goal accuracy drops by 5 to 8 percentage points in sub-freezing conditions compared to moderate temperatures between 50 and 75 degrees Fahrenheit.
What makes some NFL kickers more accurate than others?
Elite NFL kickers distinguish themselves through a combination of biomechanical consistency, mental toughness, and technical skill development. Biomechanically, top kickers achieve remarkably consistent approach angles, plant foot positioning, and ball contact points from kick to kick, with measured variability of less than 2 degrees in approach angle. Mental performance is equally critical as kickers must perform under extreme pressure with single-attempt opportunities that can determine game outcomes. Leg strength matters but technique is paramount, as the most accurate kickers optimize their swing arc to maximize both power and directional control. Modern kickers also benefit from specialized coaching, biomechanical video analysis, and sports psychology support that were less common in previous decades.
What is the longest field goal ever made in the NFL?
The NFL record for the longest field goal is 66 yards, kicked by Justin Tucker of the Baltimore Ravens in September 2021 against the Detroit Lions. The ball hit the crossbar and bounced through, making it one of the most dramatic plays in NFL history. Before Tucker, the record was 64 yards shared by Matt Prater (2013) and Tom Dempsey (1970). At 66 yards, statistical models estimate the success probability at roughly 5 to 10 percent for an elite kicker under favorable conditions. These extreme-distance kicks typically require ideal conditions including minimal wind, moderate temperature, and often high altitude like at Denver where the thinner air reduces air resistance and allows the ball to travel farther.
How do indoor stadiums affect field goal probability?
Indoor stadiums provide a controlled environment that eliminates wind and temperature as variables, resulting in measurably higher field goal success rates. NFL data consistently shows that kickers perform approximately 3 to 5 percentage points better in domed stadiums compared to outdoor venues, with the advantage increasing significantly for longer-distance attempts. The consistent footing, absence of wind gusts, and comfortable temperatures all contribute to more repeatable kicking mechanics. Retractable roof stadiums offer a hybrid advantage when the roof is closed. Teams that play in domes, such as the Atlanta Falcons and Indianapolis Colts, often see their kickers post higher season-long accuracy percentages compared to teams in outdoor cold-weather markets.
When should a coach attempt a field goal versus punting or going for it?
The decision to attempt a field goal involves expected points analysis that weighs the probability of making the kick against the cost of missing. A field goal attempt is worth 3 points times the success probability, but a miss surrenders possession at the spot of the kick (the line of scrimmage plus 7 yards for the snap). Advanced NFL analytics suggest that field goal attempts are generally advisable when the expected points from the kick exceed the expected points from punting or attempting a fourth-down conversion. As a rough guideline, kicks under 45 yards are almost always worth attempting, kicks from 45 to 52 yards depend on game situation and kicker ability, and kicks beyond 55 yards are rarely advisable unless the game situation demands it.
How does altitude affect field goal distance and accuracy?
Higher altitude significantly benefits field goal kicking because the thinner air reduces aerodynamic drag on the football. At Denver, Colorado (5,280 feet elevation), the air density is approximately 17 percent less than at sea level, allowing kicks to travel 3 to 5 yards farther with the same leg power. This is why several long-distance field goal records have been set at Mile High Stadium. The reduced air resistance also means the ball maintains its velocity longer during flight, making the trajectory flatter and more predictable. However, altitude does not significantly affect accuracy or direction control, so the benefit is primarily in extending maximum range. Kickers visiting Denver for away games also benefit from this effect, making it a venue-specific advantage rather than a home team advantage.
What role does the holder and long snapper play in field goal success?
The holder and long snapper are critical but often overlooked components of field goal success, and their performance directly affects the kicker probability calculations. The entire snap-hold-kick operation must be completed in approximately 1.3 seconds to avoid being blocked. A poor snap that is off-target, wobbly, or slow forces the holder to adjust, disrupting the timing and potentially shifting the hold position by inches that translate to feet of error at the goalposts. Elite holders position the ball at the correct angle and laces-out orientation within a fraction of a second. Research estimates that snap and hold errors contribute to approximately 3 to 5 percent of all missed field goals, and this percentage increases in adverse weather conditions when the ball is wet or cold.
How has field goal accuracy changed over the decades in the NFL?
NFL field goal accuracy has improved dramatically over the past five decades due to advances in kicker specialization, training methods, and rule changes. In the 1970s, the league-wide field goal success rate was approximately 63 percent. By the 1990s, it had risen to about 77 percent. In the 2020s, NFL kickers collectively make approximately 84 to 87 percent of their field goal attempts. Several factors drive this improvement including the transition from straight-on to soccer-style kicking in the 1970s and 1980s, the professionalization of kicker-specific coaching, improved strength and conditioning programs, better artificial playing surfaces, and the narrowing of goalpost width in 1974 which paradoxically improved kicking technique by demanding greater precision from the start.
