Decimal Odds
The total return per 1 unit staked, including stake. Standard in Europe and Asia.
Decimal odds of 2.50 mean a 1-unit winning bet returns 2.50 total (1.50 profit + 1.00 stake). They convert cleanly to probability via 1/d, which is why every quant model uses decimal internally.
Formula
payout = stake · decimal_odds profit = stake · (decimal_odds - 1)
