Which Educators Use Which Tools for Risk Calculators?
None of the 13 educators names a dedicated tool for this job. They size positions with a spreadsheet, the broker's order ticket, or simple math: account risk divided by the distance to the stop. TraderTV Live risks 1% of the account per trade; Adam Khoo sets the stop first, then sizes from account risk.
Use the calculator on this page, then check the share count against your broker's buying power.

How Do You Pick a Risk Calculator Tool?
01
Risk in dollars, not shares
The point of a position size calculator is fixing the dollar loss. Enter what you will lose if the stop hits, and let the share count fall out of the math.
02
Stop first, size second
Set the stop where the setup is proven wrong, then size from it. A stop moved to fit a size you wanted is not a stop.
03
A daily loss limit
Per-trade risk caps one loss. A daily limit caps a bad day. Your tool or broker should support both, or you should write the daily number down.
04
Speed at the moment of entry
If the math takes a minute, you'll skip it on the fast trades. A calculator in your platform, a spreadsheet tab or the one on this page should give the answer in seconds.
Mistakes That Cost Traders Money
Sizing up after a loss
Doubling size to win it back turns one bad trade into a bad month. Keep the same risk number win or lose.
Ignoring slippage
On thin stocks your exit can fill well past your stop. Trade smaller size where liquidity is thin so the real loss stays near the planned one.

Risk Calculators Questions
How do you calculate position size?
Shares = (account size × risk percentage) ÷ (entry price − stop price). With a $25,000 account, 1% risk, a $50 entry, and a $48.50 stop, you risk $250 at $1.50 a share, so you buy 166 shares. The calculator above does the math for you.
What percentage of my account should I risk per trade?
TraderTV Live teaches a 1% rule, and many educators use 1% or less. Financial Wisdom shrinks the position when the stop is wider so the dollar risk stays constant. Pick a number small enough that ten losses in a row would not take you out of the game.
