The math behind every price — convert odds, strip the vig, check a bet's expected value, size it, split an arb, hedge or chase a middle, and see what a pick'em leg needs to win. Everything runs in your browser.
American, decimal, fractional and implied probability — type in any one.
Take the bookmaker's margin out of a two-way market to get each side's fair price.
Is a price +EV? Enter the price you can get and your fair win chance (from the no-vig tool or TheEdge's model).
How much of a bankroll a given edge justifies. Most bettors use a fraction — quarter Kelly is common.
Over at one book, Under at another: when the prices allow, split the stake so both outcomes return the same.
You're holding a bet. Find the stake on the other side that locks the same result either way.
Over a lower line at one book, Under a higher line at another. Land in between and both win.
What a single leg has to win to break even on a pick'em payout. Compare it with the model's win % on any pick.
Start with the no-vig tool: it turns a two-way market into fair probabilities. That fair number is what the expected-value and Kelly tools need. TheEdge does this across every book automatically on its +EV board, and puts its own model's read next to it.
None of this is advice — prices move, and a +EV bet still loses often. These tools show the math; the decisions are yours.
