Enter the odds and your stake to see the total payout and the net profit.
The total payout is your stake multiplied by the decimal odds. The net profit is that payout minus what you risked: what you actually make if the bet wins.
If your odds are in American format, the calculator converts them to decimal automatically. Odds of ‑110 are 1.91 in decimal; +150 is 2.50.
The most common mistake when comparing two books is mixing the two figures: some advertise what you win, others what you collect. That's why they're separate here. The total payout has your stake inside it; the net profit doesn't. On $100 at 1.91, the total payout is $191.00 and the net profit $91.00.
American odds aren't symmetrical, however much the number looks it. $100 at ‑110 makes $90.91; $100 at +110 makes $110.00. The same 110 with a different sign is $19.09 apart, because the minus tells you what you have to risk to win 100 and the plus what you win risking 100.
The figure worth taking away is break-even. At ‑110 you have to hit 52.38% just to stay level — 11 bets out of every 21: 11 wins make $1,000 and 10 losses cost $1,000. Any rate below that loses money even though it looks like winning half the time.
