Decimal odds
One number that shows your total return per dollar, stake included; it's what Mise-o-jeu+ uses, written with a comma.
Decimal odds (cote décimale) show what you get back for every dollar you bet, your stake included. If you've used Mise-o-jeu+, you've seen them, French style with a comma: 2,15 instead of 2.15.
Example: $15 at 2,15
You bet $15 on the Habs at 2,15 (illustrative, not a pick).
- Total back: 15 × 2.15 = $32.25
- Profit: $32.25 minus $15 = $17.25
Anything under 2.00 is a favourite. 2.00 is even money. Over 2.00, underdog.
Converting
- To American odds, 2.00 or more: (odds minus 1) × 100. 2,15 = +115.
- Under 2.00: -100 ÷ (odds minus 1). 1,75 = -133.
- To implied probability: 1 ÷ odds. 2,15 = 46.5%.
Why they're easy
Combos are just multiplication. A two-leg parlay at 2,15 and 1,75 is 2.15 × 1.75 = 3.7625, so $20 gets you $75.25 back if both hit. Try doing that in your head with +115 and -133.
Heads up on the comma
Same number, two ways of writing it. 2,15 on a French-language screen and 2.15 on an English one pay exactly the same.
