Hold calculator
Enter the price on every outcome to see how much the book is taking, and what each side would be priced at with no margin.
How it works
Add up each outcome's implied probability. Anything above 100% is the book's margin (overround). Hold converts that into the share of handle the book keeps: 1 − 1 / total. Shopping the same bet across books is the simplest way to pay less of it.
Questions
What is hold?
The share of all money bet on a market that the book expects to keep if action is balanced. A -110 / -110 line has a 4.55% hold.
What's a normal hold on player props?
Main markets like spreads usually hold about 4 to 5%. Player props often hold more, 7 to 10% is common, and some alternate lines much more. Lower is better for you.
Hold vs. vig vs. overround?
Overround is how far the implied probabilities exceed 100% (4.76% at -110 / -110). Hold is the bookmaker's expected keep as a share of handle (4.55%). People say vig or juice for either.
Can I use it for three-way markets?
Yes. Fill in the third outcome for soccer's win / draw / win, or any market with three results.
