68% of retail investor accounts lose money when trading CFDs and spread betting. What is risk to reward ratio, and why does it matter? Understanding this fundamental concept separates successful traders from those who fall into the losing majority. The risk reward ratio quantifies potential profit against potential loss for each trade, with many experts recommending a minimum of 1:2 to achieve consistent success. This guide explains how to calculate your risk and reward ratio, explores what is risk to reward ratio in trading, and demonstrates practical applications across different markets.
What Is Risk to Reward Ratio in Trading
Defining the Risk and Reward Ratio
A risk reward ratio measures the difference between a trade entry point to a stop-loss and take-profit order. This fundamental tool enables traders to assess potential profit or loss before entering any position. The ratio compares the monetary amount at risk with the anticipated profit, expressed in a standardised format that facilitates quick decision-making.
The calculation involves two key components: risk represents the difference between entry and stop-loss, whilst reward equals the profit target above entry. For instance, if a trader risks £1 to potentially earn £3, the risk and reward ratio becomes 1:3 or 0.33. Two units of expected gain to one unit of potential loss would be represented as a 1:2 ratio. The formula follows a straightforward structure: Risk/Reward Ratio = (Entry point – stop-loss point) / (take-profit point – entry point).
In practical terms, risk is the only part of a trade traders can control. The market behaves independently, but defining the maximum acceptable loss keeps traders operational long enough to capture winning opportunities. Setting undefined risk becomes a rapid method to deplete trading capital.
Why the Ratio Matters for Trading Decisions
The risk reward ratio serves multiple functions beyond simple profit calculation. It helps investors determine the viability of potential investments and enables comparison between different opportunities by measuring the amount of risk assumed against expected returns. This comparison proves particularly valuable when evaluating multiple trading opportunities simultaneously.
Profitability remains achievable even with losing trades outnumbering winners. With a 1:2 risk reward setup, traders maintain profitability by winning just 50% of trades. A more favourable 1:3 ratio requires only a 25% win rate to break even. Consider a scenario where a trader risks £7.64 per share with a take-profit at £15.29 per share, creating a 1:2 ratio. Losing 6 out of 10 trades still generates profit: 4 winning trades earn £61.16 total, whilst 6 losses cost £45.87, resulting in a net profit of £15.29 despite a 40% win rate.
The ratio provides structure for strategic planning aligned with financial objectives. Traders seeking specific risk reward profiles adjust their strategies accordingly, leading to more disciplined trading practises. Predefined exits reduce panic and impulsive decisions, keeping traders emotionally grounded. Professional traders think from a risk reward standpoint over a sample of trades rather than individual positions, lessening emotional impact when losses occur.
Common Misconceptions About Risk vs Reward
Many traders mistakenly believe high win rates guarantee profitability. A 90% win ratio holds little value if the risk reward garnered on those trades reaches 1:0.1. Conversely, winning just 25% of trades can still grow an account long-term when paired with appropriate risk reward management. The relationship between win rates and risk reward ratios determines actual profitability, not win percentage alone.
Risk reward ratios vary considerably across different trading styles and strategies. A scalper typically operates with a high win ratio but low risk reward calculation, perhaps 1:0.5, requiring 7 wins out of 10 trades for profitability. Swing traders accept decreased win rates whilst pursuing increased risk reward, typically batting for at least a 1:2 ratio. Even with a 40% win rate, swing traders profit when maintaining proper ratios.
The notion that traders must always target 1:3 ratios oversimplifies market realities. Sometimes smaller ratios paired with higher win rates produce better results than larger ratios with lower probability setups. Market volatility can push price toward stop-loss levels before reversing to targets, making extremely wide ratios counterproductive. Most traders find maintaining ratios between 1:1.5 and 1:3 offers optimal balance between achievable targets and meaningful profit potential.
How to Calculate Your Risk Reward Ratio
The Basic Formula Explained
Calculating the risk reward ratio requires dividing potential profit by potential loss. The standard formula reads: Risk/Reward Ratio = Potential Loss / Potential Gain. This calculation produces a decimal figure that translates into ratio format. A result of 0.33 becomes 1:3, meaning the trader risks one unit to potentially gain three units.
Alternative formula structures achieve the same outcome. For long positions: Risk/Reward Ratio = (Entry Price – Stop Loss Price) / (Take Profit Price – Entry Price). Short positions reverse the calculation: Risk/Reward Ratio = (Stop Loss Price – Entry Price) / (Entry Price – Take Profit Price). Both methods quantify the distance between entry and stop-loss against the distance between entry and take-profit.
A practical example demonstrates the mechanics. Purchasing EUR/USD at 0.90021 with stop-loss at 0.88020 and take-profit at 0.94193 produces: (0.90021 – 0.88020) / (0.94193 – 0.90021) = 0.02001 / 0.04172, yielding a 1:2.08 ratio. The calculation works equally well using pips. A 40-pip risk against a 120-pip reward creates: 120/40 = 3, expressed as 1:3.
Setting Your Entry and Exit Points
Entry price establishes the reference point for all subsequent calculations. This becomes the anchor from which risk and reward measurements extend. Traders determine entry through technical analysis, identifying specific price levels where probability favours their directional bias.
Exit points split into two categories: stop-loss defines maximum acceptable loss, whilst take-profit locks in gains at predetermined levels. Setting these levels before entry removes emotion from the equation. The stop-loss typically sits just beyond support for long positions or above resistance for short positions. This placement respects market structure rather than arbitrary distances.
Take-profit targets align with nearby resistance levels for long trades or support zones for short positions. Key levels from previous highs, lows, or supply and demand zones provide logical profit targets. Setting realistic targets based on actual market structure outweighs chasing favourable ratios with unrealistic price objectives.

Working With Stop-Loss and Take-Profit Levels
A worked example clarifies the process. Entering EUR/USD long at 1.0850 with stop-loss at 1.0820 creates 30 pips of risk. Applying a 1:2 reward ratio places take-profit at 1.0910, producing 60 pips of potential reward. The trade automatically closes at either level without requiring constant monitoring.
Consider a stock purchase at £51.99 with stop-loss at £49.85, creating £2.14 risk per share. A take-profit at £58.70 generates £6.71 reward per share. This produces a 3.13:1 ratio (£6.71 / £2.14), ensuring profitability even if only one-third of trades succeed.
Stop-loss placement requires discipline. Moving stops to manufacture better ratios undermines the entire risk management framework. The market either validates the trade setup or it doesn’t. Arbitrary stop adjustments simply delay inevitable losses whilst increasing their size.
Calculating Ratio for Different Position Sizes
Position size amplifies the monetary impact without changing the ratio itself. Buying 10 shares at £198.77 with stop-loss at £168.19 creates £30.58 risk per share. The total risk becomes (£198.77 – £168.19) x 10 = £305.80. With take-profit at £305.80, expected return reaches (£305.80 – £198.77) x 10 = £1,070.29. The ratio remains 1:3.5 regardless of whether trading 10 shares or 100 shares.
What Is a Good Risk to Reward Ratio in Trading
The 1:3 Benchmark Explained
Market strategists frequently identify 1:3 as the optimal risk reward ratio for trading investments, representing three units of expected return for every unit of risk. This benchmark appeals to traders because it requires winning only 25% of trades to break even. At this threshold, three losses consuming one unit each offset by a single win capturing three units creates a neutral outcome. Winning more than one in four trades generates positive expectancy.
The mathematics behind 1:3 ratios appear attractive, yet practical implementation reveals challenges. Setups with targets three times further than stop-loss levels prove structurally harder to reach. Most traders operating genuine 1:3 strategies achieve win rates between 25% and 35%, placing them just above breakeven with minimal margin during drawdown periods. The ratio sounds impressive until execution realities emerge.
When to Use Lower Ratios (1:1 or 1:2)
Scalping strategies typically employ ratios between 1:1 and 1:1.5, compensating with higher win rates. These short-term approaches prioritise trade volume over individual profit magnitude. Day trading strategies might target 1:2 or 1:3 ratios, balancing frequent trades with favourable setups. A 1:2 ratio requires winning just 33.33% of trades to break even.
Lower ratios suit high-probability setups where confluence of multiple factors increases success likelihood. Strong trend continuation trades, particularly those with 60-70% expected win rates, perform well with 1:2 targets. Advanced traders sometimes accept 1:1 ratios when their win rates exceed 50%, though this demands consistent execution.
Adjusting Ratios Based on Trading Strategy
Swing trading systems often employ 1:3 to 1:5 ratios, accepting lower win rates for larger individual profits. The strategy matches ratio expectations to natural price movement patterns within chosen timeframes. Scalpers focus on 1:1 ratios with many small trades carrying minimal risk. Position traders targeting 1:5 or higher ratios typically achieve 30-40% win rates.
Most successful systematic trading strategies operate between 1:1.5 and 1:4 risk reward ratios, achieving win rates between 25% and 65%. Dynamic adjustments improve performance during changing market conditions. High volatility periods support wider stops and targets, whilst low volatility requires tighter ratios to prevent stops triggering from normal price noise.
Win Rate vs Risk Reward: Finding the Balance
Breakeven win rate for any ratio follows the formula: Risk / (Risk + Reward). For 1:2 ratios, breakeven sits at 33.33%; for 1:3 ratios, 25%. Mathematical expectancy combines both metrics: (Win Rate × Average Win) – (Loss Rate × Average Loss). A system with 40% win rate and 1:2.5 ratio produces expectancy of 0.4, indicating long-term profitability. Positive expectancy represents the minimum requirement for viable systems.
Practical Applications Across Different Markets
Risk Reward in Forex Trading
The principles remain consistent across financial markets, yet typical trading ranges, liquidity, and price action behaviour differ by asset class. Major currency pairs in forex offer tight spreads that allow closer stop-loss placement, making 1:2 and 1:3 ratios achievable without requiring very wide targets. Session timing affects these calculations substantially. The London open and New York overlap periods influence intraday range, directly impacting the viability of profit targets.
Calculating Ratios for Stock Positions
Share price gaps introduce additional complexity when trading equities or equity CFDs, particularly overnight. Setting stop-loss orders without accounting for gap risk means actual potential loss may exceed what the ratio suggests. This becomes especially relevant for positions held over earnings announcements or macro events. Strong trending behaviour in stock markets makes 1:3 or greater ratios achievable during sustained directional moves. However, sudden reversals driven by geopolitical news, central bank decisions, or supply shocks can invalidate well-planned positions rapidly.
Using the Ratio in Options Trading
Options trading requires understanding the distinction between maximum and average profit-loss ratios. Most option trades offer multiple outcomes beyond simply maximum profit or maximum loss. A bull call spread position, for instance, makes maximum profit above the higher strike, maximum loss below the lower strike, and something in between within the strike range. Average profit and average loss can prove much smaller than the maximums. The break-even risk-reward ratios should consider average profit and average loss rather than maximums, though maximum ratios serve as practical proxies for pre-trade evaluation.
Adapting the Ratio for Cryptocurrency Markets
High volatility distinguishes cryptocurrency markets from traditional assets. Average true range indicators help place stop-loss levels that account for market volatility, preventing early exits from normal price fluctuations. Small ratios like 1:1 typically suit scalping strategies but prove risky in crypto’s volatile environment.
Managing Risk Through Proper Position Sizing
Determining Capital at Risk Per Trade
Most retail investors risk no more than 2% of their investment capital on any one trade. Fund managers typically risk less than this amount. For a £25,000 account, maximum account risk equals £500 per trade (2% × £25,000). Even losing 10 consecutive trades depletes only 20% of capital. This percentage-based approach ensures survival through inevitable losing streaks. Setting daily loss limits at 2-3% and weekly limits at 5-6% prevents revenge trades.
Using Stop-Loss Orders Effectively
Stop-loss orders remove emotion from trading decisions. Behavioural finance research confirms investors typically hold losing positions too long whilst selling winners too early. Stop-losses nullify this tendency. Placement should respect market context rather than arbitrary percentages. Stable securities might warrant 5-8% stops below purchase price, whilst volatile growth stocks could require 10-15% stops. Widening stops to avoid taking losses represents a critical error. Trailing stops adjust upward as prices move favourably, locking in profits automatically.
Portfolio-Level Risk Management
Portfolio risk management focuses on events impacting strategic objectives across multiple positions. Monitoring total equity used as margin indicates overall exposure levels. Higher equity-used ratios signal greater potential profits but also elevated risk. Setting a 15% drawdown limit commits traders to reassessing strategy after reaching this threshold.
Avoiding Emotional Trading Decisions
Studies show 80% of trading mistakes stem from emotions rather than technical flaws. Emotional trading causes traders to abandon plans, overtrade, and risk excessive amounts. Elite traders observe emotions and use them as data rather than suppressing them. Journaling trades alongside emotional states reveals patterns showing vulnerability to poor decisions. Reducing risk to 0.25-0.5% per trade during drawdowns decreases emotional pressure.
Monitoring and Adjusting Active Positions
Traders must continuously ask whether setups remain valid. Moving stop-loss into profit or taking partial profits secures gains as trades progress. Consider closing trades early if price action structure changes radically or if price stalls unreasonably long at major support or resistance zones. Stop-losses should only move in the direction of trades to lock profits or reduce risk, never further into negative territory.
Conclusion – What Is Risk to Reward Ratio
Risk-reward ratios separate profitable traders from those who deplete their accounts. This guide demonstrated how to calculate ratios using entry points, stop-losses, and take-profits across multiple markets. The 1:3 benchmark provides a useful starting point, yet different trading styles demand different ratios. Scalpers succeed with 1:1 ratios and high win rates, whilst swing traders accept lower win rates for 1:3 or greater rewards.
Accordingly, profitability emerges from the relationship between win rate and ratio, not from either metric alone. A trader winning 40% of trades remains profitable with proper 1:2 ratios. The mathematics proves straightforward, yet execution requires discipline. Predefined stops and targets remove emotional decisions that destroy trading capital. Position sizing at 2% maximum risk per trade ensures survival through inevitable losing streaks, allowing successful setups to generate long-term growth.
What is considered a good risk to reward ratio for trading?
Most traders aim for a minimum risk to reward ratio of 1:2, though 1:3 is often cited as optimal. However, the “best” ratio depends on your trading style. Scalpers may use 1:1 ratios with high win rates, whilst swing traders typically target 1:3 or higher ratios with lower win rates. The key is finding a balance between your win rate and ratio that produces positive expectancy over time.
Should I always aim for the highest possible risk reward ratio?
Not necessarily. Whilst higher ratios like 1:5 sound attractive, they’re structurally harder to achieve as targets sit much further from entry points. Extremely wide ratios often result in very low win rates that barely exceed breakeven. Most successful traders maintain ratios between 1:1.5 and 1:3, which offer a practical balance between achievable targets and meaningful profit potential.
How do I calculate the risk reward ratio for a trade?
Divide your potential profit by your potential loss. The formula is: (Take-Profit Price – Entry Price) / (Entry Price – Stop-Loss Price). For example, if you enter at £100, set stop-loss at £95, and take-profit at £115, your calculation is (£115 – £100) / (£100 – £95) = £15 / £5 = 3, giving you a 1:3 ratio.
How much capital should one risk per trade?
Most retail traders risk no more than 2% of their total trading capital on any single trade. For a £25,000 account, this means risking a maximum of £500 per trade. This percentage-based approach ensures you can survive inevitable losing streaks—even 10 consecutive losses would only deplete 20% of your capital, allowing you to continue trading and capture winning opportunities.
