Standard over under odds in the US are -110 on each side. That price is not arbitrary — it is the sportsbook's built-in commission, and understanding it is the first step toward betting totals intelligently.

What Does -110 Mean on an Over Under Bet?

American odds of -110 mean you must risk $110 to profit $100. Bet $100 and you profit $90.91, for a total return of $190.91. The extra amount beyond your stake is the book's cut, called the vig or juice.

How Does the 4.76% Hold Work?

When both sides of a total are priced at -110, the sportsbook's overround is approximately 4.76%. Here is the math: -110 implies a win probability of 52.38%. Add both sides: 52.38% + 52.38% = 104.76%. The excess 4.76% is the book's margin on every dollar wagered.

That means the book keeps roughly $4.76 out of every $100 in handle over time, regardless of which side wins.

Odds Per Side Implied Probability Book Hold Bettor Break-Even Win Rate
-110 / -110 (standard) 52.38% ~4.76% 52.38%
-105 / -105 (reduced juice) 51.22% ~2.38% 51.22%
-120 / +100 (asymmetric) 54.55% / 50% ~4.55% Varies by side

Why Must You Win More Than Half Your Bets?

At -110, winning 50% of your over under bets is not enough. You need to win at least 52.38% just to break even. That implied probability figure is the foundation of any honest totals strategy.

The full calculation — and what it means for long-run returns — is covered on the Implied Probability: The Break-Even Rate Every Totals Bettor Must Know page.

What Is Reduced Juice and How Much Does It Save?

Some sportsbooks price totals at -105 per side instead of -110. That cuts the book's hold to approximately 2.38% — roughly half the standard margin. For a bettor placing volume wagers on NFL totals, that difference compounds meaningfully over a full season.

How Do Game Totals Compare to Other Markets?

Not all over under bets carry the same vig. Futures totals run overrounds of 20–40%. Player prop over/unders carry roughly 5–7%. Standard game totals at -110/-110 run approximately 4.76%. Game totals are the most bettor-friendly market by overround.

When Odds Are Not Symmetrical

Sportsbooks sometimes price a total asymmetrically — for example, Over -120 / Under +100. That signals sharp money has hit one side hard. The book shifts the price to balance exposure. The Over Under Betting Strategy: Reading Line Movement and Finding Value guide explains how to interpret that signal.

All gambling winnings — including totals payouts — are taxable federal income. The IRS requires a W-2G when net winnings exceed $600 and are at least 300× the wager. Details are in the Taxes on Over Under Winnings: W-2G Thresholds and Federal Rules for 2026 guide. Official withholding rules are published in the IRS Instructions for Forms W-2G and 5754 (Rev. January 2026).
