How Much to Risk Per Trade — The 1% Rule Explained

The difference between traders who survive and traders who blow up comes down to one number: the percentage of their account they risk on each trade. Get this wrong and no amount of technical analysis will save you. Get this right and even a mediocre strategy becomes profitable over time.

The 1% Rule — What It Is and Why It Works

The 1% rule states: never risk more than 1% of your total trading account on a single trade. Period.

• $10,000 account = $100 max risk per trade
• $25,000 account = $250 max risk per trade
• $50,000 account = $500 max risk per trade
• $100,000 account = $1,000 max risk per trade

This is not your position size. This is your maximum acceptable loss if the trade goes against you and hits your stop loss. Your position size (number of shares) is calculated from this dollar risk divided by your stop loss distance.

The Math Behind Survival

Here is what consecutive losing trades do to your account at different risk levels:

Consecutive Losses	0.5% Risk	1% Risk	2% Risk	3% Risk	5% Risk
5 losses	-2.5%	-4.9%	-9.6%	-14.1%	-22.6%
10 losses	-4.9%	-9.6%	-18.3%	-26.3%	-40.1%
15 losses	-7.2%	-14.0%	-26.1%	-36.7%	-53.7%
20 losses	-9.5%	-18.2%	-33.2%	-45.6%	-64.2%
30 losses	-13.9%	-26.0%	-45.5%	-59.5%	-78.5%

At 1% risk, losing 20 trades in a row costs you 18.2% of your account. Painful but recoverable. At 5% risk, those same 20 losses wipe out 64% of your account. The math is not opinion — it is compounding losses working against you.

Risk Percentage by Trader Type

Trader Type	Recommended Risk	Why
Complete beginner	0.25-0.5%	Learning phase. Mistakes are guaranteed. Preserve capital while building skills
Developing trader	0.5-1%	Strategy forming but not yet consistent. Need room for losing streaks
Consistent trader	1-2%	Proven edge over 100+ trades. Can handle the drawdown emotionally and financially
Prop firm trader	0.5-1%	Firms have maximum drawdown rules (5-10%). Must stay well under the limit
Swing trader	1-2%	Fewer trades per week means each trade can carry slightly more risk
Scalper	0.25-0.5%	Many trades per day. Small risk per trade prevents catastrophic losing days

How Risk Percentage Connects to Position Size

Your risk percentage is meaningless without position sizing. Here is the connection:

1. Account: $30,000
2. Risk: 1% = $300 dollar risk
3. Entry: $45.00 per share
4. Stop loss: $42.00 per share
5. Risk per share: $45 - $42 = $3.00
6. Position size: $300 / $3 = 100 shares
7. Position value: 100 x $45 = $4,500 (15% of account)

Notice that the position value ($4,500) is only 15% of the account even though you are risking 1%. Position value and risk are different things. You can invest $4,500 in a trade and only risk $300 if your stop loss is tight.

The Biggest Risk Management Mistakes

• Risking "whatever feels right": Feelings change with your last trade. After a win, you feel invincible and risk too much. After a loss, you either revenge trade bigger or chicken out and trade too small. A fixed percentage removes emotion from the equation
• Moving your stop loss to avoid a loss: You planned to risk 1%. Your trade drops to your stop level. Instead of taking the $300 loss, you move the stop further away. Now you are risking 3%, 5%, or your entire position with no exit plan
• Risking more after winning streaks: Five wins in a row does not mean the sixth trade is guaranteed. The market does not reward streaks. Keep your risk percentage constant
• Ignoring correlation: Buying three tech stocks at 2% risk each means you have 6% of your account exposed to the same sector. If tech drops, all three positions lose simultaneously
