Your 40-Yard Dash
Speed starts with power. The exact strength, plyometric, and recovery sequence to build explosive athleticism — delivered straight to your inbox.
Enter your time, pick your position and choose who to compare against. The calculator converts hand times to an electronic equivalent, then estimates your percentile using the average and elite (top 10%) times for your position at that level. It also shows your average speed in mph, which NFL positions your time would match, and your Speed Score if you add bodyweight.
Benchmarks come from the same data used in our average 40-yard dash times by age, position and level guide. Percentiles are estimates, not official rankings.
Hand-timed 40s usually come out 0.2 to 0.3 seconds faster than electronic times, because the timer reacts to the start late and stops the watch early. NFL combine times are fully electronic, so this calculator adds 0.24 seconds to hand times before comparing. A hand-timed 4.45 is really closer to a 4.69 on a laser.

Speed Score adjusts a 40 time for bodyweight, so a 230-pound back running 4.50 gets more credit than a 190-pound back running the same time. The formula is (weight × 200) ÷ (40 time⁴). A score around 100 is typical for an NFL running back prospect, and 110 or higher is excellent. It's most useful for running backs, tight ends and edge rushers, where size and speed both matter.
Most of a 40 is won in the first 10 yards. Focus on start mechanics (stance, first two steps, shin angles), acceleration work like sled pushes and resisted sprints, and lower-body strength through squats, trap bar deadlifts and hip thrusts. Our complete guide to running a faster 40 lays out the full program. A focused 8–12 week block typically takes 0.1 to 0.3 seconds off.
