How to Use the Perpetual Contract Calculator on BYDFi (PC)

Understanding your potential profit, loss, and liquidation risks before entering a trade is essential for any futures trader. To help users make informed decisions, BYDFi offers a built-in Perpetual Contract Calculator that simplifies key trading computations — from PNL to liquidation price.

This guide will walk you through how to access and effectively use the Perpetual Contract Calculator on the PC versions of BYDFi.

🔢 What Is the Perpetual Contract Calculator?

The Perpetual Contract Calculator allows you to simulate trade outcomes and assess risk before opening a position. It provides calculations for:

• PNL (Profit and Loss)
• Target Price
