Free Strength Calculators

No signup, no ads, pounds or kilograms. Each one uses the same validated math that runs inside Ægir Iron, and each links to the app if you want the number tracked automatically over time.

Powerlifting Score Calculator

All three scores side by side: Wilks-2, DOTS and IPF GL (Goodlift) from one set of numbers.

DOTS Calculator

Your DOTS score from your total and bodyweight, with what the number means and how it is worked out.

Wilks Calculator

Your Wilks-2 score, plus why it differs from the original Wilks coefficient your old results were quoted in.

IPF GL Points Calculator

Goodlift points on the IPF Classic coefficients, the score that ranks you at IPF-affiliated competition.

One-Rep Max Calculator

Estimate your 1RM from reps, or reps and RPE, using the RTS chart with an Epley fallback.

Strength Standards

See where your lifts land from beginner to elite for your bodyweight and sex.
