Percent Risk Per Trade and Account Balance Loss Over Time

Consecutive Losing Trades Required to Reach Drawdown Levels

The table below shows the number of consecutive losing trades required to reach different account drawdown levels when risking a fixed percentage of the current account balance on each trade.

Assumptions:

• Risk is recalculated after every trade based on the new account balance.
• Every trade is a loss.
• Position sizing compounds downward as the account decreases.
• Values are rounded up to the nearest whole trade.

Example

Use the interactive calculator below to see how different risk levels and account balances affect your drawdown after consecutive losses:

Key Observations

• Lower risk per trade dramatically increases account survival during losing streaks.
• At 1% risk per trade, it requires approximately 69 consecutive losses to lose half the account.
• At 2% risk per trade, approximately 35 consecutive losses results in a 50% drawdown.
• At 5% risk per trade, only 14 consecutive losses can halve the account.
• Percentage-based risk prevents a true 100% loss because the dollar amount risked decreases as the account balance declines.

The Edge of Reward to Risk Ratio

The tables above assume every trade is a loss, which is the worst-case scenario. In reality, trading is not about winning every trade — it is about making more on your winning trades than you lose on your losing ones. This is the concept of reward to risk ratio (R:R).

A reward to risk ratio compares how much you stand to gain on a trade versus how much you are willing to lose. For example:

• A 1:1 R:R ratio means you risk 1 to make 1.
• A 2:1 R:R ratio means you risk 1 to make 2.
• A 3:1 R:R ratio means you risk 1 to make 3.
• A 4:1 R:R ratio means you risk 1 to make 4.
• A 5:1 R:R ratio means you risk 1 to make 5.

When you combine a reasonable win rate with a reward to risk ratio greater than 1:1, you can be profitable even if you lose more trades than you win.

Example: How R:R Ratio Compensates for Losses

The key to understanding R:R is that your risk per trade stays the same — only your potential profit changes. The table below shows what each R:R ratio means in practice:

Now, consider a trader who takes 20 trades at each ratio. Even with a win rate below 50%, higher R:R ratios can still be profitable:

Key Takeaways

• At a 1:1 ratio, you need at least a 50% win rate just to break even.
• At a 2:1 ratio, you only need a 33% win rate to break even (2 wins × 2% = 4%, 4 losses × 1% = 4%).
• At a 3:1 ratio, you only need a 25% win rate to break even (3 wins × 3% = 9%, 7 losses × 1% = 7%).
• At a 4:1 ratio, you only need a 20% win rate to break even (1 win × 4% = 4%, 4 losses × 1% = 4%).
• At a 5:1 ratio, you only need a 17% win rate to break even (1 win × 5% = 5%, 5 losses × 1% = 5%).

This is why experienced traders focus on setups where the potential reward significantly outweighs the risk. Even with a win rate below 50%, a higher R:R ratio keeps the account growing over time. Combined with the position sizing shown in the tables above, a disciplined approach to reward to risk is one of the most effective edges a trader can have.
