Free Betting Odds Calculator | Calculate Your Return

Single Bet

A wager on a single selection. The simplest form of betting.

Parlay (Accumulator)

Combines multiple selections into one bet. All selections must win for the bet to pay out. Higher risk, higher reward.

Teaser

Similar to a parlay, but you get favorable point spreads in exchange for lower odds. Popular in basketball and football.

Pleaser

The opposite of a teaser. You take less favorable point spreads in exchange for higher potential payouts.

Decimal Odds (European)

Represents the total return for each unit staked. Example: Odds of 2.50 means a $100 bet returns $250 total ($150 profit + $100 stake).

Fractional Odds (UK)

Shows potential profit relative to stake. Example: 5/1 means you win $5 for every $1 staked, plus your stake back.

American Odds (Moneyline)

Positive number (+150) shows profit on a $100 stake. Negative number (-150) shows how much to stake to win $100.

Implied Probability

The likelihood of an outcome expressed as a percentage, derived from the odds.

The calculator opens with "Single Bet" selected by default, but you can switch between four bet types: Single Bet, Parlay, Teaser, and Pleaser.

Understand the risk

Using a betting calculator gives you a clearer idea of the potential risk involved. If you place wagers without checking the odds, you may make weaker betting decisions than you would if you calculated them carefully.

Simplify your betting

With a bet calculator, odds are quicker and easier to understand. Efficiency is crucial when wagering on in-play events.

Compare odds

Betting calculators can be helpful when comparing odds across different betting sites to find the best opportunities.

Take a more organised approach

If you place multiple bets at the same time and make impulsive wagering decisions, using a bet odds calculator will help you get more organised. You can strategically explore the best options and take a more cautious approach.
