About BullCalc

BullCalc is an independent website with free calculators for crypto traders. It was built by traders who were tired of doing position size and liquidation math by hand, or trusting a number they could not check.

What we do

We build simple, fast tools that answer the questions traders ask before every trade: How big should my position be? Where will I get liquidated? How much will fees and funding cost? What is my risk compared to my reward?

Each calculator shows the formula it uses and a worked example, so you can understand the result and check it yourself.

How we work

• Free and no signup. Every tool can be used without an account.
• Private by design. Calculations run in your browser. We do not store what you enter.
• Transparent. Formulas and assumptions are written on every page.
• Independent. We are not owned by or affiliated with any exchange.

How the site is funded

BullCalc is supported by advertising, including Google AdSense and clearly labelled sponsored placements. Advertisers do not influence our calculators or their results.

Not financial advice

Our tools are for education and planning. They do not tell you what to buy or sell. Read our disclaimer for details.
