Max Shares by Risk Calculator
Calculate max shares you can buy without exceeding risk budget.
Use this deterministic max-shares-by-risk calculator to keep position size within a fixed dollar loss limit.
Results
Maximum shares (whole)
238
With $1,000.00 max risk and $4.20 risk/share, size up to 238 whole shares.
- Max risk amount
- $1,000.00
- Risk per share
- $4.20
- Max shares (fractional)
- 238.0952
- Max shares (whole)
- 238
Formula
Max Shares = Max Risk ÷ (Entry Price - Stop Price)
Example
- Max risk amount: 1000
- Entry price: 74.3
- Stop price: 70.1
What does this mean?
- •Output is the maximum position size allowed by risk budget.
- •If entry equals stop, risk per share is zero and sizing is undefined.
- •Use whole-share rounding rules that match your execution setup.
