Risk-Reward Ratio in Trading: Calculation, Realities & Planned vs. Realized R:R
The risk-reward ratio (R:R) compares the prospective profit of a trade against the potential loss defined by your stop loss. Expressed as a ratio such as 1:2 or 1:3, it indicates how many units of reward you plan to make for each unit of risk. Crucially, professional performance analysis differentiates between Planned R:R (what your chart looked like before entering) and Realized R:R (what you actually took home after slippage, fees, and early exits).
The risk-reward ratio measures potential gain relative to potential loss. A minimum planned R:R of 1:2 allows a strategy to remain profitable with a win rate as low as 35% to 40%.
Risk-Reward Ratio = (Take-Profit Price - Entry Price) ÷ (Entry Price - Stop-Loss Price)How to Calculate Risk-Reward Ratio
For a long position, your risk is the distance between your entry price and your invalidation stop loss. Your reward is the distance between your entry price and your planned profit target.
- Target Distance:Take-Profit Price minus Entry Price
- Stop Distance:Entry Price minus Stop-Loss Price
Entry at $150.00. Stop loss at $145.00 ($5 risk). Profit target at $165.00 ($15 reward).
Planned R:R vs. Realized R:R: The Great Execution Gap
Almost every retail trader plans trades with an attractive 1:2 or 1:3 ratio. Yet when you audit their completed journal, their actual realized ratio is often 1:0.8 or 1:1.1.
Why does this gap exist?
- Fear of Giving Back Profits: As soon as a trade shows green, anxiety prompts the trader to close early before reaching the full target.
- Letting Losers Run: Holding a losing trade past the intended stop price in hopes of a reversal, transforming a planned -1.0R loss into -2.0R.
- Execution Friction: Spread costs, broker commissions, and slippage on market orders shave percentage points off every winner.
Breakeven Win Rate Formula
The higher your realized reward-to-risk ratio, the fewer winning trades you need to maintain positive expectancy:
- Reward Multiple:The reward side of your R:R ratio (e.g., 2.0 for 1:2)
Calculate the minimum win rate needed for a 1:2.5 risk-to-reward ratio.
- Risk-reward ratio measures potential gain per unit of capital risked.
- Higher R:R ratios significantly reduce the win rate required to maintain profitability.
- Compare your Planned R:R against your Realized R:R to diagnose premature exit habits.
- A 1:2 ratio means risking $1 to make $2, requiring only a 33.4% win rate to break even.
