Hi, I work on Canada Bet Guide, an affiliate-supported Canadian sportsbook and casino review site. I built a free, no-login odds calculator for American, decimal and fractional prices. I will use this thread for transparent odds-math examples, not picks or promises of results.
Worked example: +150 = 2.50 = 3/2. The implied probability is 1 / 2.50 = 40%. If a C$100 cash bet wins at that price, total return is C$250 and net profit is C$150. At -200 = 1.50, implied probability is 66.67%; a winning C$100 stake returns C$150 total and C$50 profit.
Those percentages describe the quoted prices, not the true chances of winning. A single bookmaker price also includes its margin. The calculator uses the same currency as the stake you enter; it does not convert currencies or account for fees, taxes, voids and free-bet terms.

Disclosure: I work on the linked site. The wider site contains affiliate-supported operator reviews; the calculator itself needs no account. If a format or payout calculation is confusing, I am happy to work through the arithmetic here.
