Position Sizing Calculator
Free Position sizing Calculator for crypto & forex. Enter your numbers to see returns, costs, and optimized scenarios instantly.
Formula
Lot Size = (Account Balance × Risk %) / (Stop Loss Pips × Pip Value)
Position size (units) = (Account Balance × Risk%) / (Entry Price − Stop Loss Price). Unlike lot-size calculators that work in forex lot increments, this version outputs position size in shares or units for equities and crypto. Enter your account size, the percentage you are willing to lose per trade, and your entry/stop prices to find the exact number of units to buy.
Worked Examples
Example 1: Conservative Risk Management
Problem: Account: $5,000 | Risk: 1% | Stop Loss: 25 pips on EUR/USD
Solution: Risk amount = $5,000 × 1% = $50\nPip value per standard lot = $10\nLot size = $50 / (25 × $10) = 0.20 standard lots\n= 2.0 mini lots = 20 micro lots
Result: Trade 0.20 standard lots (20,000 units)
Example 2: Aggressive Day Trading
Problem: Account: $25,000 | Risk: 2% | Stop Loss: 15 pips on GBP/USD
Solution: Risk amount = $25,000 × 2% = $500\nPip value per standard lot = $10\nLot size = $500 / (15 × $10) = 3.33 standard lots\n= 333,000 units
Result: Trade 3.33 standard lots (maximum risk: $500)
