Frequently Asked Questions
What is a good win rate in sports betting?
A good win rate depends on the average odds. At -110 odds, you need approximately 52.4% to break even. At +150 average odds, you only need about 40%. Win rate alone doesn’t indicate profitability — ROI is a better measure.
What is ROI in betting?
Return on Investment (ROI) measures your profit as a percentage of total amount staked. A positive ROI means you’re profitable. Professional bettors typically achieve 2-10% ROI over the long term.
How many bets do I need for meaningful results?
You generally need at least 500-1000 bets for statistically meaningful results. Short-term results (under 100 bets) are heavily influenced by variance and don’t reliably indicate skill or edge.
How do I improve my betting results?
Focus on positive expected value (+EV) bets, track your closing line value (CLV), specialize in specific sports or markets, maintain disciplined bankroll management, and continuously analyze your results to identify strengths and weaknesses.
