Why we built this
Most calculator sites bury the tool you need under ads, pop-ups, and a sign-up wall. AthleticCalcs exists to do the opposite: pick a calculator, enter your numbers, get your result. No account, no email capture, no clutter between you and the answer.
What we cover
We focus on strength training and athletic performance — the calculators lifters and athletes actually reach for week to week: one-rep max, bench press, squat, and deadlift estimates, Wilks scoring and powerlifting totals for comparing strength across bodyweight classes, and vertical jump and dunk calculators for athletes training explosiveness.
Instant results
Every calculator runs entirely in your browser. No page reloads, no waiting.
Real formulas
Epley, Brzycki, Wilks, and other established formulas — never a black-box guess.
No accounts
Nothing to sign up for, nothing stored. Your numbers stay in your browser.
A note on accuracy
Every calculator on this site produces an estimate, not a guarantee. Rep-max formulas, Wilks scoring, and jump calculators are all built on established models, but individual factors — technique, fatigue, leverages — mean your real number can vary. Use these tools to plan training and track trends, not as a substitute for testing under safe, coached conditions.
