About Bench Press Calculator
Free, accurate strength tools built by lifters, for lifters.
Our Mission
Bench Press Calculator exists to take the guesswork out of strength training. Whether you're chasing your first plate or grinding toward a 315 bench, knowing your numbers lets you train smarter, program with intent and measure real progress.
What We Offer
A suite of specialised calculators covering everything from a straightforward 1RM estimate to 5/3/1 cycles, RPE autoregulation, plate loading, strength standards and cross-lift conversions. Every tool runs instantly in your browser, supports both pounds and kilograms, and is completely free.
How It Works
Our estimates draw on established strength-science formulas — Epley, Brzycki, Lander, Lombardi and O'Conner — cross-referenced for balance. Standards and ratios are based on widely accepted lift-to-bodyweight benchmarks.
A Note on Accuracy
These calculators provide estimates, not medical or coaching advice. Always lift within your ability, use a spotter for heavy work, and consult a qualified professional before starting any new program.
