Deftly move between multiple price formats using our Odds Converter.

The Odds Converter lets you switch instantly between American, decimal, and fractional odds — and see the implied probability behind every number.

When choosing between two different lines, how do you know which one is the superior number? Our Compare Lines Calculator moves through exact half-point values for both spreads and totals so you can make the sharpest decisions down to the penny.

Find out just what your bet is worth with the Closing Line Value Calculator. It's one of the most important tools for serious sports bettors.

Enter the line you bet and the market's closing line to instantly see your CLV and know whether your wager was plus-EV.

Hedging a bet is about so much more than just managing risk. When done optimally, it maximizes bankroll growth.

Our Hedge Betting Calculator works through the complex math behind every hedge, factoring in bankroll size, probability, and amount you stand to win to show you how much to hedge, and when.

No matter whether you're protecting a future or reducing exposure through in-game markets, this calculator helps you execute a mathematically sound hedging strategy across multiple sportsbooks.

Find out exactly what the sportsbook’s hold percentage is on any market, even multi-way markets like futures.

The Hold Calculator reveals the book’s margin (a.k.a. the house edge), so you know what you have to overcome on your bet.

Use it to compare hold percentages across sportsbooks, and avoid markets where it’s toughest to beat the house.

Find fair prices for alternate spreads and totals — and uncover value where other bettors aren't looking.

Unabated’s Alternate Lines Calculator uses cutting-edge data science to model every alt price point, helping you exploit sportsbook inefficiencies even when mainline sides and totals aren't showing any edge.

The Partial Game Derivatives Calculator lets you price halves, quarters, and periods to find hidden edges the market overlooks.

By breaking down the relationship between full-game and partial-game pricing, you can identify plus-EV spots  and scoop up the value other bettors leave on the table.

Unabated’s Teaser Calculator shows when teaser prices cross key numbers and produce plus-EV results. Quickly test 2-leg, 3-leg, or other combinations — and know instantly when the points justify the price.
