Risk Planning
Position Size Calculator
Estimate how many shares or units fit a defined risk budget before opening a trade. Use the result as a planning reference alongside liquidity, volatility, chart structure, and your own research.
Trade Inputs
The calculator uses the absolute distance between entry and stop, so it works for long or short planning. It does not account for slippage, commissions, taxes, borrow fees, liquidity, or trading restrictions.
Define risk first
Start with the dollar amount or account percentage you are willing to risk before comparing potential reward.
Respect the stop distance
A wider stop reduces the number of shares or units that fit the same risk budget.
Check real-world costs
Slippage, commissions, taxes, borrow fees, and liquidity can change the actual result.
Educational use only
This calculator is for research and education. It does not tell you whether to buy, sell, short, or hold any security, and it does not account for your financial situation.
