About MarginPad

MarginPad is a free set of precision calculators for crypto futures traders — answering the questions that matter on every leveraged trade, with no ads, no signups and no tracking of your inputs.

Why it exists

Most trading calculators are buried inside exchange interfaces or smothered in ads, and they rarely let you plan a trade before you open it. MarginPad fixes that — clean calculators and a full Trade Planner that run entirely in your browser.

Our principles

Private by default: calculations run locally and your inputs never leave your device. Free forever: no paywalls, no signup, funded by optional exchange referral links. Accurate and transparent: the exact formulas are published on our blog. Global: available in 13 languages.

A note on risk

MarginPad is an educational tool, not financial advice. Calculations are estimates and may differ from your exchange. Crypto futures trading carries a substantial risk of loss — never trade money you can't afford to lose.
