Stop-Loss Distance
How This Stop Distance Was Calculated
How to Calculate Stop-Loss Distance
A stop-loss distance measures how far your planned stop is from your entry price. You can express that distance in dollars per share or as a percentage of the entry price.
For a long position, the stop price is normally below the entry price. For a short position, the stop price is normally above the entry price.
Stop Distance and Position Risk
Stop distance is only one part of risk management. A wider stop creates more risk per share, while a tighter stop creates less risk per share.
The number of shares you own determines how that per-share risk affects your overall portfolio. Two investors can use the exact same stop-loss price and still have completely different dollar risk because their position sizes are different.

What Your Stop-Loss Result Means
A stop-loss calculation measures the distance between your planned entry price and the price where you intend to exit if the position moves against you.
For example:
Entry Price: $50
Stop-Loss Price: $45
Your stop distance is:
$50 − $45 = $5 per share
Your stop-loss percentage is:
$5 ÷ $50 × 100 = 10%
That means your planned stop is approximately 10% below your entry price.
It does not mean your portfolio is risking 10%.
The percentage only describes the distance between your entry and stop.
Your actual dollar risk depends on how many shares you own.
How to Calculate Stop-Loss Distance
Stop-loss distance is based on two numbers:
Entry price
Stop-loss price
The calculation is straightforward.
Step 1: Calculate Dollar Stop Distance
For a long position:
Stop Distance = Entry Price − Stop-Loss Price
Example:
Entry: $100
Stop: $94
Stop Distance: $6 per share
Step 2: Calculate Stop-Loss Percentage
Divide the dollar stop distance by the entry price.
Stop-Loss % = Stop Distance ÷ Entry Price × 100
Using the example:
$6 ÷ $100 × 100 = 6%
That produces a:
6% stop-loss distance
Stop-Loss Calculation Example
Let's look at a complete example.
Planned Trade
Entry Price: $80
Stop-Loss Price: $74
Dollar Stop Distance
$80 − $74 = $6 per share
Percentage Stop Distance
$6 ÷ $80 × 100 = 7.5%
Result:
$6 per share
and
7.5% below the entry price
That tells you how far the stock could move against your entry before reaching the planned stop.
It does not tell you how much money you would lose.
That depends on your position size.
What Is a Good Stop-Loss Percentage?
There is no single stop-loss percentage that is appropriate for every investment or trading strategy.
Some investors may use relatively tight stops.
Others may allow more room depending on:
Stock volatility
Support and resistance
Recent price structure
Time horizon
Investment strategy
Market conditions
Position size
The important part is having a reason for the stop.
For example:
| Stop Distance | What It Means |
|---|---|
| 2% | Stop is 2% away from entry |
| 5% | Stop is 5% away from entry |
| 10% | Stop is 10% away from entry |
| 15% | Stop is 15% away from entry |
A wider stop does not automatically mean a trade is riskier.
Position size matters.
A wide stop paired with a smaller position can create less total dollar risk than a tight stop paired with a very large position.
Why Stop-Loss Distance Matters
Most investors naturally focus on one question:
How much could this stock go up?
Stop-loss planning forces you to ask another question:
Where am I wrong?
That matters.
Before entering a position, you should have some idea of what price movement, chart break, or change in your original thesis would cause you to reconsider the trade.
Your stop gives that decision a defined level.
Instead of waiting until the stock falls and making an emotional decision, you can think about the downside before your money is committed.
Stop-Loss Percentage Is Not Portfolio Risk
This is one of the most important concepts to understand.
Suppose two investors buy the same stock at $50.
Both use a stop at $45.
Their stop distance is:
$5 per share
or
10%
But Investor A owns 50 shares.
Investor B owns 1,000 shares.
Investor A
50 shares × $5 risk per share = $250 planned risk
Investor B
1,000 shares × $5 risk per share = $5,000 planned risk
Both investors are using the exact same 10% stop.
Their actual dollar exposure is completely different.
That is why a stop-loss percentage should never be evaluated without considering position size.
How Does Position Size Affect Stop-Loss Risk?
Position size converts your stop distance into actual dollar risk.
The basic relationship is:
Total Planned Risk = Stop Distance × Number of Shares
Example:
Entry: $100
Stop: $95
Stop Distance: $5
Position A
100 shares
$5 × 100 = $500 planned risk
Position B
500 shares
$5 × 500 = $2,500 planned risk
The stop did not change.
The position size changed.
This is why stop-loss planning and position sizing should work together.
Should You Use a Fixed Stop-Loss Percentage?
Not necessarily.
Some strategies use fixed percentage stops as part of a written system.
But automatically placing every stop 5%, 8%, or 10% below your entry can ignore what the stock is actually doing.
For example:
A stock may have an important support level 6% below your entry.
Another stock may have normal daily volatility of 7%.
Using the same 5% stop on both positions may not make sense.
The stop should fit the logic of the trade.
A percentage is useful for measuring the distance.
It should not automatically determine where the stop belongs.
How Should You Choose a Stop-Loss Price?
A stop should generally represent a level where your original reasoning for entering the position needs to be reconsidered.
Depending on your strategy, that may involve:
Support levels
Resistance levels
Recent swing lows
Recent swing highs
Moving averages
Volatility
Chart structure
Trend changes
Fundamental developments
Your original investment thesis
For a long position, you might determine that a break below an important support level invalidates the setup.
For a short position, you might determine that a move above resistance invalidates the setup.
The calculator does not choose that level for you.
It measures the distance once you choose it.
Don't Move Your Stop Just to Buy More Shares
Suppose you want to buy a stock at $50.
Your analysis suggests the trade is invalid below $42.
That creates:
$8 of risk per share
You calculate your position size and discover that your risk limit only allows you to buy 100 shares.
It may be tempting to move the stop to $48 so the calculator allows a much larger position.
That reverses the process.
The better sequence is:
Determine where the trade is wrong.
Calculate the stop distance.
Determine how many shares fit your risk limit.
If a logical stop requires a smaller position, the position should usually get smaller.
The stop should not be manipulated simply to justify owning more shares.
Can a Stop Loss Guarantee My Risk?
No.
A stop-loss order does not guarantee that your position will exit at the exact stop price.
Markets can gap through your stop.
This may happen after:
Earnings reports
Major company news
Economic announcements
Market shocks
Overnight events
Trading halts
Low-liquidity periods
For example:
Entry: $50
Stop: $45
A company releases unexpected bad news overnight.
The stock opens the next morning at $39.
Your actual exit may occur well below the $45 stop price.
That means your actual loss could be larger than the amount you planned.
Stop-loss calculations are estimates.
They help define risk.
They do not eliminate it.
What Is the Difference Between a Stop Loss and Position Sizing?
These tools answer two different questions.
Stop Loss
How far is my planned exit from my entry price?
Position Sizing
How many shares can I buy while staying within my risk limit?
You generally want to consider both.
For example:
Your Stop-Loss Calculator may show:
Entry: $50
Stop: $45
Stop Distance: $5
Stop Percentage: 10%
Your Position Size Calculator may then show that only 200 shares fit within your maximum portfolio-risk limit.
That is useful information.
One tool defines the distance.
The other helps determine how much capital to commit.
What Is the Difference Between Stop Loss and Risk/Reward?
A stop-loss defines your planned downside.
Risk/reward compares that downside with your potential upside.
For example:
Entry: $50
Stop: $45
Target: $65
Your stop distance is:
$5 per share
Your potential reward is:
$15 per share
Your Risk/Reward Calculator would compare those numbers and produce:
1:3
The Stop-Loss Calculator helps define one side of the trade.
The Risk/Reward Calculator compares both sides.
How Should I Interpret My Result?
Treat your stop distance as one part of your investment plan.
Before making a decision, ask:
The calculator answers:
How far is my planned stop from my entry?
It does not answer:
Is this the correct place for my stop?
That requires a broader decision process.
Why am I entering this position?
Where is my thesis invalidated?
Is the stop based on a logical price level?
How volatile is the stock?
How much am I risking per share?
How many shares can I own?
What percentage of my portfolio is at risk?
Is my profit target realistic?
Does the risk/reward make sense?
Am I following a written plan?
The calculator answers:
How far is my planned stop from my entry?
It does not answer:
Is this the correct place for my stop?
That requires a broader decision process.
