A Lot Size Calculator is an essential pre-trade risk management tool that determines the exact volume (Standard, Mini, or Micro lots) you should open on a trade. It bridges your account equity, your maximum risk percentage, and your technical stop-loss distance.
Without calculating lot sizes properly, traders often risk random amounts of capital per trade—sometimes exposing 5% or 10% of their account on a single volatile setup. This tool ensures your monetary risk remains strictly controlled.
Whether your stop loss is 20 pips or 100 pips away, a lot size calculator adjusts your volume so your dollar risk stays identical.
By locking risk at 1% or 2% per trade, you can endure a standard losing streak without threatening your overall account solvency.
Takes the guesswork out of order execution, letting you focus entirely on chart analysis and edge execution.
Enter your total current trading account equity in dollars (e.g., $10,000).
Define the maximum percentage of capital you are willing to lose if the trade hits your stop loss (standard is 1% or 2%).
Input your technical stop-loss distance in pips. The calculator instantly generates your safe lot size and micro lot breakdown.
