Our free bet calculator helps you calculate potential winnings from your bets. Simply enter your stake amount and the odds offered by your sportsbook to see your potential payout. The calculator supports decimal odds (common in Europe), fractional odds (UK), and American odds (US).
Most common in CS2 betting. Shows total return per unit staked. Example: 2.50 odds means $10 bet returns $25 total.
Popular in UK. Shows profit relative to stake. Example: 3/2 means $10 bet wins $15 profit ($25 total).
Common in US. Positive shows profit on $100 bet, negative shows stake needed to win $100. Example: +150 means $100 wins $150 profit.
An accumulator (parlay) combines multiple selections into one bet. All selections must win for the bet to pay out. The combined odds are calculated by multiplying all individual odds together. While accumulators offer higher potential returns, they also carry more risk since all selections must be correct.
Example: Three CS2 match bets at 1.80, 2.10, and 1.65 odds combine to 6.24 total odds (1.80 × 2.10 × 1.65 = 6.237). A $10 accumulator at these odds would return $62.37 if all three matches win.
To calculate your potential payout, multiply your stake by the decimal odds. For example, a $10 bet at 2.50 odds returns $25 ($10 × 2.50 = $25 total, $15 profit).
For positive American odds (+200), divide by 100 and add 1: (+200/100) + 1 = 3.00 decimal. For negative odds (-150), divide 100 by the odds and add 1: (100/150) + 1 = 1.67 decimal.
Implied probability is the bookmaker's estimated chance of an outcome occurring, derived from the odds. For decimal odds, divide 1 by the odds: 1/2.50 = 40% implied probability.
An accumulator (or parlay) combines multiple selections into one bet. All selections must win for the bet to pay out. The odds multiply together, offering higher potential returns but higher risk.
