What Is Hold Percentage?

Hold (or overround) is the sportsbook's built-in margin on a market. It represents the percentage of total money wagered that the sportsbook expects to keep as profit, regardless of the outcome.

The Formula

Hold% = (1/decimal_a + 1/decimal_b - 1) × 100

What's a Good Hold?

Standard -110/-110 lines have a hold of about 4.5%. Sharp sportsbooks may offer holds as low as 2-3%, while recreational books can have holds of 6%+ on some markets. Lower hold = better value for bettors.
