Which sportsbook has the lowest vig?
The standard -110/-110 line carries 4.76% vig. Almost every list of low-vig books stops there and repeats what each book says about itself. We measured it instead: the last price before the start on the main moneyline, spread and total at every book, across more than 2,500 NFL, college football, NBA, NHL, MLB and WNBA games.
The score below gives every league and bet type the same weight, so a book that lists more baseball does not look cheaper because of it. Vig here is the two win chances added together, minus 100%.
| Book | All main lines | Moneyline | Spread | Total | Cost per $1,000 bet |
|---|---|---|---|---|---|
| Pinnacle | 3.48% | 2.96% | 3.52% | 3.97% | $34 |
| BetMGM | 4.63% | 4.51% | 4.62% | 4.77% | $44 |
| Caesars | 4.69% | 4.46% | 4.70% | 4.92% | $45 |
| Fanatics | 4.81% | 4.62% | 5.07% | 4.83% | $46 |
| theScore Bet | 4.81% | 4.46% | 5.02% | 5.03% | $46 |
| BetParx | 4.81% | 4.80% | 4.75% | 4.86% | $46 |
| Hard Rock Bet | 4.85% | 4.60% | 5.18% | 4.79% | $46 |
| DraftKings | 4.88% | 4.49% | 5.04% | 5.10% | $47 |
| BetRivers | 5.10% | 4.96% | 5.02% | 5.27% | $49 |
| FanDuel | 5.12% | 4.67% | 5.33% | 5.35% | $49 |
| BallyBet | 5.30% | 5.55% | 5.06% | 5.30% | $50 |
| bet365 | 5.76% | 5.20% | 5.96% | 6.11% | $54 |
Cost per $1,000 is what the vig takes over time from a bettor who wins exactly as often as the fair price says. The gap from the cheapest big book to the most expensive is 1.1 points, or about $10 on every $1,000 bet.
Moneylines are the cheapest thing on the board at almost every book, and totals the most expensive. Caesars lists fewer spreads than the rest, so its overall number leans more on moneylines and totals.
Lowest vig by league and bet type
The ranking moves a lot once you pick a sport. FanDuel is one of the more expensive books overall and the cheapest big book on MLB moneylines at 3.57%. BetMGM is the cheapest big book on NFL spreads at 4.02%, while bet365 is at 6.52% on the same bet.

Why a second account beats a low-vig book
Moving your whole budget from a typical big book to the cheapest saves about 0.2 points of vig. Having a second account and taking the better of two prices saves about 0.8 points on average, and it works with any two books. By five books the vig you actually pay is down to 3.42%, level with Pinnacle, without an account there.
This is the real answer to the low-vig question. No book is cheapest everywhere, so the lowest vig belongs to whoever is holding two or three accounts on the day.
What about Pinnacle, offshore books and exchanges?
Pinnacle is the benchmark at 3.48%. Among the offshore names, Bet105 came in at 3.50%, LowVig at 3.66%, BetOnline at 4.37%, BetUS at 4.49% and Bovada at 4.76%, so an offshore label alone does not mean a cheap price.
Exchanges and prediction markets look far cheaper because their prices barely carry a gap: Novig 0.81%, Kalshi 1.16%, ProphetX 1.18%, Matchbook 1.72%. That is not the whole cost, because they charge a fee or commission on top of the price and their depth can be thin. Compare them on the price after fees.
How we measured it
We took each book's last price before the start on the main line, the pair closest to even, on full-game moneylines, spreads and totals. A price has to have been on the board within 30 minutes of the start. Games with fewer than three books are out, and so are pairs that are not true two-way markets. A book needs at least 30 lines in a league and bet type for that cell to count, and at least 9 of the 18 cells to be ranked.
The overall score is the plain average of the cells a book has. Vig here is the win chances added together minus 100%, the same number the calculators on this site and most others show.
How to pay less vig
1. Open a second sportsbook account before you hunt for a cheaper single book. Two prices beat one almost every time.
2. Know your sport. Use the league switch above, because the cheapest book changes by league and by bet type.
3. Remove the vig from the price you are about to take to see the fair number it is built on.
4. Compare the line and the price at every book on the odds board, then bet where both are best.

Lowest vig sportsbooks: what every book really charges: questions
What is the vig on DraftKings?
About 4.88% on main game lines: 4.49% on moneylines, 5.04% on spreads and 5.10% on totals.
What is the vig on FanDuel?
About 5.12% on main game lines: 4.67% on moneylines, 5.33% on spreads and 5.35% on totals. It drops to 3.57% on MLB moneylines.
Which sportsbook has the best odds overall?
BetMGM and Caesars have the lowest vig of the big US books, but no book is best everywhere. Taking the better of two books saves nearly as much as moving from the most expensive book to the cheapest.
Is -105 vig a real thing at US sportsbooks?
Rarely on a main line at the big books. A -105/-105 line is 2.44% vig, and none of the big books average close to that on main lines.
What is the vig on Kalshi and Polymarket?
Kalshi prices carry a gap of about 1.16% on main game lines, and Polymarket close to zero. Each charges or can charge fees on top, so compare prices after fees.
How much does vig cost me?
At 4.76% vig, a bettor who wins exactly the fair share loses about $45 for every $1,000 bet. The gap between big books is worth about $10 of that.
