BtrBet equips you with professional-grade metrics to evaluate your betting like a disciplined portfolio manager. Instead of relying on vibes or guesswork, you can use data to understand what’s working, what’s not, and where your edge truly lies.
| Metric | Measures | Best used for |
|---|---|---|
| Win rate | % of bets won | Surface-level consistency tracking |
| ROI | Profit per dollar risked | Core profitability metric |
| Sharpe ratio | Return per unit of total variance | Evaluating consistency and stability |
| Sortino ratio | Return per unit of downside risk | Evaluating efficiency of risk versus harmful losses |
Win rate
Your win rate is the percentage of bets you’ve won out of all bets placed. It’s the simplest and most familiar metric in sports betting, often used as a baseline for success.
Win rate is a quick indicator of consistency. If your win rate is extremely low, it’s likely that something fundamental is off with your strategy or execution. If it’s high, it might suggest strong performance—but that isn’t always the case.
A high win rate can be misleading if you’re consistently betting heavy favorites or laying high juice. For example, someone winning 60% of bets at -150 odds might still be losing money. Similarly, a low win rate might be fine if you’re betting longshots or alt-lines with large payouts. Win rate alone doesn’t account for the size of your wins and losses.
Break down your win rate by sport, league, market, and odds range in your Recap. This helps you identify where you’re most consistent and where you might be overestimating your edge.
ROI (Return on Investment)
Return on Investment (ROI) tells you how much profit (or loss) you’re making for every dollar staked. Unlike win rate, ROI accounts for odds and payout size, making it a more accurate measure of profitability.
ROI is the gold standard for assessing the overall performance of a betting strategy. It adjusts for how much risk you’re taking on and reveals whether your approach is profitable over time. A positive ROI means your strategy is beating the vig and the market. A negative ROI means you’re leaking money—even if your win rate looks good.
ROI can fluctuate heavily with small sample sizes, especially if you hit or miss a few large bets. It’s important to look at ROI trends over time, and across different bet types or odds bands, rather than relying on a single number.
Use the filters in the Recap page to isolate ROI by specific sports, leagues, markets, bet types, or by odds range. This helps you identify where your ROI is strongest—and where to cut losses.
Sharpe ratio
The Sharpe ratio is a risk-adjusted performance metric. It measures how much return you're earning for each unit of total volatility (both upside and downside). Think of it as your return-per-risk ratio.
Not all ROI is equal. A bettor with a 10% ROI and low variance is far more reliable than someone with the same ROI but wild swings in performance. The Sharpe ratio helps distinguish between stable strategies and lucky streaks. A high Sharpe ratio (typically >1.0) suggests strong and consistent edge; a negative ratio indicates that your strategy is both unprofitable and volatile.
Sharpe penalizes all volatility—including big wins. If you’re betting longshots or high-variance props, your Sharpe ratio may be lower even if your strategy is solid. Use it as a tool to understand consistency, not just profitability.
BtrBet calculates a Sharpe ratio across your entire portfolio and broken down by sport, market, and odds range. Compare the Sharpe ratios across these segments to identify where you’re consistent and where you’re swinging wildly.
Sortino ratio
The Sortino ratio is a close cousin of the Sharpe ratio—but smarter. It only considers downside volatility (i.e., losses), ignoring the "risk" of big wins. This makes it especially useful for bettors with high-upside strategies.
Your Sortino ratio tells you how much return you're generating per unit of harmful risk. If you’re taking smart swings—like betting alt-lines, props, or underdogs—Sortino rewards you for winning big, even if your results are volatile. A high Sortino ratio suggests you're managing downside risk well while still producing strong returns.
If your Sortino and Sharpe ratios are similar, it means your volatility is mostly downside—likely a sign that your edge isn’t real or your sizing is off. If your Sortino ratio is much higher than your Sharpe ratio, you’re generating good returns with most of your variance coming from wins—not losses.
BtrBet calculates a Sortino ratio for your entire portfolio and segmented by bet type, odds range, and more. Use it to identify where you’re generating efficient upside and where your losses are dragging you down.
