How to use it
Enter your stock entry price, your stop-loss price, and how many shares you hold. The calculator returns the total dollars you’d lose if the stop is hit, that loss as a percentage of your entry, the risk per share, and the position’s value.
The math
loss = |entry − stop| × shares, and the percentage is the per-share loss divided by
the entry. It’s the fastest way to check that a stock trade’s risk fits your plan before you take
it — and it pairs naturally with the position size
calculator, which works the other direction to set your share count from a target risk.
