Free calculators
Check any number by hand.
The same math the Antic tools use, free. Each calculator shows its working, so you can see where every number comes from.
Type your own odds. The answer updates as you go.
Expected Value
Work out what a bet is worth on average, from its odds and your chance of winning.
Kelly Criterion
Size each bet to grow your bankroll as fast as possible, given your edge.
No-Vig Fair Odds
Remove a book's margin from its odds to get the fair price, with no house edge.
Arbitrage
Split your stakes across two books so each side pays the same amount, or hedge an existing bet.
Middle
Check whether two opposite bets at different numbers leave a gap wide enough to be worth it.
Hold
Measure the hold, or vig, that a market's odds build in. Lower hold means fairer prices.
Parlay
Work out a parlay's payout and implied hit chance from the odds on each leg.
Odds Converter
Convert American and decimal odds, and see the implied probability each price carries.
Bonus Bet Converter
Turn a bonus bet into cash: the hedge to place on the other side, and the cash you keep whichever side wins.
Calculators show math, not advice. Antic never places bets. Bet only where it is legal for you.
