How Much Should You Risk Per Trade? The 1% Rule

Every trader has losing streaks. How much you risk on each trade decides whether a streak is a small setback or the end of your account. The 1% rule is a simple way to keep losses small. Here is how to apply it, with the numbers you can check in the [Forex Risk Calculator](/forex/risk-calculator).

What the 1% rule means

The 1% rule says the most you should lose on one trade, if your stop-loss is hit, is 1% of your account. It does not mean you only use 1% of your money — it limits the loss, not the position.

Money at risk = Account balance × Risk %
Pip value needed = Money at risk ÷ Stop-loss in pips
Lot size = Pip value needed ÷ Pip value per standard lot
Stop-loss in pips
Distance from entry to your stop
Pip value per standard lot
About $10 for pairs quoted in USD, such as EUR/USD

Worked example: $5,000 account, 40-pip stop

Worked example

Applying the 1% rule on EUR/USD

  1. Account balance: $5,000
  2. Money at risk: $5,000 × 1% = $50
  3. Stop-loss: 40 pips
  4. Pip value needed: $50 ÷ 40 = $1.25 per pip
  5. Lot size: $1.25 ÷ $10 = 0.125 standard lots (12,500 units)
  6. If the stop is hit: 40 pips × $1.25 = −$50

Most brokers round to 0.01 lots, so you would trade 0.12 lots and risk about $48.

Account size vs losing streak

This table shows what is left of a $5,000 account after a run of losing trades, when each trade risks a fixed percentage of the current balance.

Starting balance $5,000. Balance × (1 − risk)^losses, rounded. Fees and slippage not included.
Risk per tradeAfter 5 lossesAfter 10 lossesAfter 20 losses
1%$4,755$4,522$4,090
2%$4,520$4,085$3,338
5%$3,869$2,994$1,792

At 5% risk, twenty losses leave just $1,792, and you would need a gain of about 179% just to get back to $5,000. At 1%, you would need about 22%. Smaller risk keeps you in the game long enough for a good strategy to work.

Choosing your risk percentage

  • 1% or less: common for beginners and for larger accounts.
  • 2%: an upper limit many traders use.
  • Above 2%: losing streaks quickly do serious damage.

Putting the rule to work

  1. Decide your risk % before you look at the chart.
  2. Place your stop where the trade idea is proven wrong.
  3. Calculate the money at risk and lot size in the Forex Risk Calculator or Forex Position Size Calculator.
  4. Set a take-profit with a reward you are happy with, checked in the Forex Risk/Reward Calculator.
  5. Track drawdowns with the Forex Drawdown Calculator.

Leverage lets you open positions much larger than your account, which makes sticking to a risk limit even more important. This guide is educational, not trading advice.
