Free, data-backed tools that answer the questions athletes, parents, and coaches actually ask: how do my numbers compare, and what's realistic to work toward next?
Athlete Calculator is a set of free, no-signup tools for measuring and understanding athletic performance. Our calculators cover vertical jump percentile, sprint and 40-yard dash speed, squat strength standards, broad jump distance, and dunk eligibility — each one built to answer a specific, practical question rather than to just spit out a raw number.
Every calculator is paired with reference data pulled from combine results, sport-specific research, and age-based normative charts, so a result comes with context: not just "your vertical jump is 28 inches," but where that number sits relative to your age, sport, and level of competition.
Most athletic testing calculators online are either outdated, missing context, or built around a single generic standard that doesn't account for age, sport, or position. We built Athlete Calculator to fix that: current data, clear percentile breakdowns, and tools that work whether you're a 14-year-old checking your vertical jump against your age group or a coach benchmarking a roster against combine standards.
Alongside the calculators, we publish regular articles and breakdowns covering combine results, training camp storylines, and the athletic numbers behind current sports news — because the tools are more useful with real context behind them.
Our percentile and standard charts are built from publicly available combine data, peer-reviewed sport science research, and established age-based normative tables. We update these regularly as new combine classes and research come out, and we link to source context wherever it's useful. We're not a substitute for professional coaching or medical advice — think of these tools as a fast, free way to get oriented, not a replacement for individualized training guidance.
