What Is an Odds Calculator?

An odds calculator is a must-have tool for any sports bettor. It allows you to quickly convert betting odds between different formats – American, Decimal, and Fractional – and instantly calculate your potential return and net profit based on your stake.

Different countries use different types of odds:

• 🇺🇸 American odds (e.g. +150 or -200) are standard in the United States.

• 🇪🇺 Decimal odds (e.g. 2.50) are common across Europe and online sportsbooks.

• 🇬🇧 Fractional odds (e.g. 5/2 or 4/5) are traditional in the UK and Ireland.

If you’re comparing bets across different platforms or tipsters – or just want to understand how much you stand to win – this tool saves you time and ensures accuracy.

Straight Odds vs Parlay Odds

Wondering whether this tool works for single picks and parlays? It does, you can easily calculate in seconds the odds for you bet. Here’s outlined the differences between a single pick and parlay bet:

✅ Straight Odds

A straight bet is a single wager on one outcome. The odds calculator will instantly show your return based on your stake and the odds you enter. Perfect for moneylines, spreads, and over/unders.

🔗 Parlay Odds

A parlay bet combines two or more picks into one. To calculate total parlay odds, use our the Parlay Builder toggle inside the tool on this page to stack multiple selections. Then plug the final combined odds into this odds calculator to see your full payout potential.

With both tools working together, you can break down complex parlay bets or simple straight picks in seconds.
