Choose from three common odds formats:

• Decimal (e.g., 2.50): Popular in Canada, Europe and Australia, this shows your total return per $1 staked.
• American (e.g., +150 or -200): Standard in the US, showing how much you win on a $100 bet (positive odds) or how much you need to stake to win $100 (negative odds).
• Fractional (e.g., 5/2):  Traditional in the UK, showing how much profit you make relative to your stake.

Want to switch between formats? Use our Odds Converter to easily convert between decimal, American, and fractional odds.

Our calculator supports both single bets and parlays:

• A single bet is a straightforward wager on one outcome.
• A parlay (or accumulator) combines multiple bets into one. All selections must win for the parlay to pay out. While parlays carry higher risk, they also offer bigger potential rewards because the odds multiply with each leg you add.

Popular in horse racing, an each-way bet is essentially two bets in one: one for the selection to win, and one for it to finish in a place (i.e., 2nd, 3rd or 4th) as defined by the bet terms). An each-way bet can act as a safety net if your selection does not win or as a bonus if it does.

• If your selection wins, both parts of the bet pay out.
• If it only places, you still get a payout, usually at reduced odds.

Each-way terms (like 1/4, 1/5, or 1/3) refer to the fraction of the odds paid out on the place part of the bet. Some events offer each-way place only bets, meaning you can’t bet to win outright.

You should be aware a $10 each-way bet would mean a total stake of $20, $10 on the win part and $10 on the place part.

• Profit is how much you make after getting your original stake back.
• Returns include both your profit and your initial stake.

For example, if you stake $10 at odds of 3.00 (decimal), your return is $30, and your profit is $20.

Our Bet Calculator is the fastest way to work out your potential returns, profit, and implied probability, whether you're betting on a single outcome, building a parlay, or placing an each-way wager. By understanding key terms, you'll have a clearer picture of your bets and what you stand to win. Use the calculator to take the guesswork out of betting and make smarter, more informed decisions.
