        What is Win Loss Ratio?

        Win loss ratio is the number of wins divided by the number of losses. A trader with 30 wins and 20 losses has a 1.5:1 win-loss ratio. Combined with average win/loss size, this ratio determines overall profitability. A 1:1 ratio is break-even only if average win size equals average loss size.

        Win loss ratios are tracked in sports (team records), trading (profit/loss analysis), sales (deal conversion), gaming (player rankings), and legal (case outcomes). The ratio alone doesn't tell the full story — the magnitude of wins versus losses matters equally.

        Formulas & Equations Used

        This Win Loss Ratio Calculator uses the following core equations:

        1 Win Loss Ratio ▼
        W/L Ratio = Wins / Losses

        45 wins and 30 losses: W/L = 45/30 = 1.50:1.

        2 Win Rate Percentage ▼
        Win Rate = (Wins / Total Games) × 100

        45 wins in 75 games: Win Rate = (45/75) × 100 = 60%.

        3 Profit Factor (Trading) ▼
        Profit Factor = (Wins × Avg Win) / (Losses × Avg Loss)

        30 wins × $500 avg / 20 losses × $400 avg = $15,000/$8,000 = 1.875.

        Example Problems & Step-by-Step Solutions

        Here are 3 worked examples using this Win Loss Ratio Calculator:

        Example 1 Team record: 42 wins, 28 losses
        1 W/L Ratio = 42/28 = 1.50:1
        2 Win Rate = 42/70 × 100 = 60%
        3 Loss Rate = 28/70 × 100 = 40%
        ✓ 1.50:1 ratio, 60% win rate
        Example 2 Trading: 55 wins ($200 avg), 45 losses ($150 avg)
        1 W/L Ratio = 55/45 = 1.22:1
        2 Gross Wins: 55 × $200 = $11,000
        3 Gross Losses: 45 × $150 = $6,750
        4 Net Profit: $11,000 - $6,750 = $4,250
        ✓ 1.22:1 ratio, $4,250 net profit
        Example 3 Sales: 18 deals won, 32 lost, 10 pending
        1 W/L Ratio (closed) = 18/32 = 0.56:1
        2 Win Rate (closed) = 18/50 × 100 = 36%
        3 Including pending: 18/60 total = 30% conversion
        ✓ 0.56:1 ratio, 36% closed win rate

        Frequently Asked Questions

        What is a good win loss ratio? ▼

        In sports, above 1.0 (50%+) is winning. In trading, 1.0 is break-even only if average win = average loss. Many successful traders have a 0.8:1 ratio but win big and lose small, still profiting overall.

        How does win loss ratio affect trading profitability? ▼

        Profitability depends on BOTH win rate and risk-reward ratio. A 40% win rate with 3:1 reward-risk is profitable: (0.4 × 3) - (0.6 × 1) = 0.6 units profit per trade. Win rate alone is misleading.

        What is the difference between win rate and win loss ratio? ▼

        Win rate = wins/total (percentage of all outcomes that are wins). Win-loss ratio = wins/losses (direct comparison). A 60% win rate means 60 wins in 100 games, which is a 60:40 = 1.5:1 W/L ratio.

        How do I improve my win loss ratio? ▼

        In trading: improve entry criteria, use tighter stops, and let winners run. In sports: analyze losses for patterns. In sales: qualify leads better before investing time.

        Should I track draws/ties in win loss ratio? ▼

        Draws can be excluded (W/L ignoring draws), included as half-wins, or tracked separately. In chess ratings, draws count as half a point. In sales, 'no decision' outcomes are tracked separately from losses.

        Learn About Ratios

        What is a ratio?

        A ratio is a comparison between two or more quantities showing the relative size of one to another. Written as A : B, it means 'for every A units of the first quantity, there are B units of the second.' For example, a ratio of 3 : 4 means for every 3 parts of A, there are 4 parts of B. Ratios are used in cooking, construction, finance, science, and everyday life.

        How do I solve a proportion?

        A proportion is an equation that says two ratios are equal: A : B = C : D. To solve for a missing value, use cross-multiplication. If D is unknown: D = (B × C) / A. This works because in equal ratios, the cross products are always equal: A × D = B × C. Our Proportion Solver does this automatically — just enter any 3 values and it finds the 4th.

        How do I simplify a ratio?

        To simplify a ratio, find the Greatest Common Divisor (GCD) of both numbers and divide each by it. For example, 24 : 36 — the GCD of 24 and 36 is 12. So 24 ÷ 12 = 2 and 36 ÷ 12 = 3, giving the simplified ratio 2 : 3. Our Simplifier automatically finds the GCD and reduces your ratio to its lowest terms.

        What is ratio scaling and when is it useful?

        Scaling a ratio means multiplying both parts by the same factor to create an equivalent, larger (or smaller) ratio. For instance, scaling 2 : 5 by a factor of 3 gives 6 : 15. This is extremely useful for recipes (tripling a recipe), construction (scaling blueprints), mixing solutions, or any scenario where you need to maintain the same proportion at a different magnitude.

        What's the difference between a ratio and a fraction?

        A ratio A : B compares two quantities to each other (part-to-part), while a fraction A/B typically represents a part-to-whole relationship. However, any ratio can be expressed as a fraction: 3 : 4 is equivalent to 3/4 = 0.75. The key difference is context — ratios compare quantities side-by-side, while fractions represent a portion of a total.
