Betting Odds Calculator
Know exactly what a bet pays before you place it. Enter your stake in CAD and the odds in decimal, American or fractional format — the calculator shows your total payout, profit, implied probability and the same price in every format.
Reading a price like a pro
Every bet is a price, and the calculator turns that price into three plain numbers: what you get back, what you actually win, and how often the bet must land to break even. Decimal 1.91 (the standard -110 line) implies 52.4% — so a coin-flip market at that price quietly charges you the bookmaker's margin. Seeing that number before you bet is the simplest guard-rail there is.
Prices differ between sportsbooks, so the same wager can pay noticeably more at one licensed operator than another — compare before you place it. And keep the basics: set a budget, use deposit limits, never chase losses. 19+, play responsibly.
Frequently asked questions
How do I calculate a bet payout?
Multiply your stake by the decimal odds: a $25 bet at 1.91 returns $47.75 in total ($22.75 profit). With American odds, convert to decimal first (-110 → 1.91, +150 → 2.50) and multiply the same way.
What is the difference between payout and profit?
Payout is the total the sportsbook returns to you, including your original stake. Profit is the payout minus your stake — the amount you actually win.
What does -110 mean?
You must bet $110 to win $100 of profit ($210 total payout). It is the classic price on point spreads and totals, equal to decimal 1.91, and the extra $10 relative to even money is the bookmaker's margin (the 'vig').
What does +150 mean?
A $100 bet wins $150 of profit ($250 total payout). Positive American odds mark the underdog side; +150 equals decimal 2.50 and an implied probability of 40%.
How is implied probability useful?
It converts a price into a break-even win rate: odds of 1.91 imply 52.4%. If you would not expect the bet to win at least that often, the price is not worth taking. Comparing prices across licensed sportsbooks helps you find the best value.
