Fair probability = each side's implied probability ÷ the sum of all sides. The fair odds are 1 ÷ that fair probability. Only bet when your price beats the fair price.

How to remove the vig
in 3 steps

1

Turn each price into a chance

Each price gives a chance: 1 ÷ decimal odds. A -110 line is 1.91 decimal, or about a 52.4% chance.

2

Add the chances up

Add the chances for every side. Two -110 sides total about 104.8%. The 4.8% over 100% is the bookmaker's cut, called the hold.

3

Scale back to 100%

Divide each chance by that total so the sides add up to exactly 100%. That is the fair chance, and 1 ÷ fair % is the fair price.

Worked example: a -110 / -110 market

The standard two-way line every bettor sees.

Side	Price	Implied %	Fair %
Side A	-110	52.4%	50.0%
Side B	-110	52.4%	50.0%
Total	—	104.8%	100.0%

The book's two sides add up to 104.8%, a 4.8% hold. Scaled back, each side is a true 50/50, so the fair price is +100 (2.00 decimal). Any time you can back that side at better than +100, the price pays more than it should.

No-vig:
quick answers

What is the vig (juice / hold)?

The bookmaker's built-in margin. Across a market the chances the prices give add up to more than 100%. That extra is the vig, also called juice or the hold.

How do I remove it?

Turn each price into a chance (1 ÷ decimal odds), add them up, then divide each by that total so they add up to 100%.

What's a typical hold percentage?

A standard two-way market like -110 / -110 holds about 4.5%. Some books run 2-3%. Smaller markets and player props can be 6% or more.
