Sport margin decoder
Compare bookmaker margins across sports to find soft markets
Compare margins across sports within one bookmaker to identify which markets they price softly.
Why bookmakers have soft spots
No bookmaker is sharp on every sport. They invest in football and tennis but skimp on volleyball, esports, niche horse racing, or table tennis. Margins on these markets can be 8-15% — but pricing accuracy is often weak, meaning value bets are easier to find. This calculator helps you find a bookmaker's soft markets relative to their sharp ones. Use No-vig for individual market fair odds and Margin calculator for single-market analysis.
