KEY TAKEAWAYS
Payout language trips up many readers because the same payout can be written several ways. A bet that pays 35 to 1, one that pays 36 for 1 and a decimal price of 36.00 all describe the same return, and each hides a different detail about whether the stake is included. This glossary defines 22 gambling payout terms in plain language, each with a worked example in which the numbers have been checked. It is written for readers who read paytables and betting slips and want to know exactly what a stated payout returns, and for anyone comparing a payout with the real chance of winning. The terms are grouped into four sets: stakes, payouts and returns; price language; value and mispricing; and charges, limits and cancellations. Definitions are descriptive and neutral. They explain how payouts are written and compared, and they do not suggest any bet. Terms for probability and odds formats appear in the other glossaries of this category, and a quick-reference table follows the entries.
Stakes, Payouts and Returns
These terms describe what goes in, what a winning bet pays and how a payout is written.
Stake
Definition: The amount of money risked on a single bet. When the bet wins, the stake is normally returned along with the winnings; when it loses, the stake is lost.
Example: “A $10 stake at 3.00 returns $30 in total.”
Also called the wager.
Total return
Definition: The full amount a winning bet pays back, counting the stake. Total return = stake × decimal odds, and subtracting the stake leaves the profit.
Example: “A $20 stake at +150 has a total return of $50 (20 × 2.50) and a profit of $30.”
Betting slips often show this figure before the result.
Payout odds
Definition: The odds a bet actually pays when it wins, as opposed to the true odds of the outcome. When payout odds are lower than true odds, the difference is the advantage built into the bet for the house or the book.
Example: “Straight-up roulette pays 35 to 1 even though the true odds are longer.”
Compare with true odds.
True odds
Definition: Odds that match an outcome’s real chance, with no margin added. They compare the ways to lose with the ways to win. A single number on an American wheel has one winning pocket and 37 others, so the true odds are 37 to 1 against.
Example: “The true odds are 37 to 1, but the table pays 35 to 1.”
The gap between 37 to 1 and 35 to 1 produces the 5.26% house edge on that wheel.
To-one payout
Definition: A payout written as “X to 1”: the winner receives X units of profit for each unit staked, and the stake is also returned. A bet that pays 35 to 1 returns 36 units in total per unit staked.
Example: “A $5 straight-up roulette win at 35 to 1 pays $175 profit, so $180 comes back.”
The form most casino payout tables use.
For-one payout
Definition: A payout written as “X for 1”: the total return per unit staked, with the stake already counted. 36 for 1 returns 36 units in total, which is the same as 35 to 1.
Example: “A $1 bet at 36 for 1 returns $36 in total, a profit of $35.”
“X for 1” always pays one unit less profit than “X to 1.”
Payout ratio
Definition: A payout written as a ratio of profit to units staked, such as 3 to 2 or 6 to 5. A $10 bet at 3 to 2 earns $15 profit, and at 6 to 5 it earns $12.
Example: “Blackjack naturals pay 3 to 2 at standard tables.”
Some blackjack tables pay 6 to 5, which returns less on the same bet.
Price Language
Bettors often talk about prices rather than odds. These terms describe how a price compares and how it moves.
Price
Definition: The odds offered on an outcome, in whichever format the market uses, such as +150, 2.50 or 3/2.
Example: “The price on the home side is 2.50.”
Often used interchangeably with odds.
Short price
Definition: A low price, which means the outcome is considered likely. Decimal odds near 1.00 are short; at 1.20 the implied probability is 83.33% (1 ÷ 1.20).
Example: “At 1.20, the favorite is a very short price.”
Opposite of a long price.
Long price
Definition: A high price, which means the outcome is considered unlikely. At 11.00 in decimal odds the implied probability is 9.09% (1 ÷ 11.00).
Example: “She’s a long price at 11.00.”
Opposite of a short price.
Shortening
Definition: A fall in the odds on an outcome, usually because more money arrives on it. A price moving from 4.00 to 3.20 shortens, so the implied probability rises from 25.00% to 31.25%.
Example: “The favorite shortened from 2.50 to 1.80 before the start.”
Opposite of drifting.
Drifting
Definition: A rise in the odds on an outcome, usually because less money is arriving on it. A price moving from 3.00 to 3.75 drifts, so the implied probability falls from 33.33% to 26.67%.
Example: “The second choice drifted out to 3.75.”
Opposite of shortening.
Starting price
Definition: The odds on an outcome at the moment an event begins. In racing it is the price at the start of the race, and in some markets a bet can be placed or settled at that price whatever the odds were earlier.
Example: “He took the starting price instead of the early odds.”
Often shortened to SP.
Value and Mispricing
These terms compare a price with an estimate of the chance. Estimates are opinions, and none of these terms promises a result.
Overlay
Definition: A selection whose odds are higher than its chance of winning appears to justify. In racing it describes a horse going off at higher odds than its past performances suggest. If a bettor rates a horse a 1-in-4 chance, the fair odds are 3-1, so 6-1 is an overlay.
Example: “At 6-1 she’s an overlay if you rate her one chance in four.”
A judgment about price versus chance, and judgments can be wrong.
Underlay
Definition: The opposite of an overlay: a selection whose odds are lower than its chance of winning appears to justify. With a 1-in-4 rating, fair odds are 3-1, so 2-1 is an underlay.
Example: “At 2-1 he’s an underlay.”
Also a judgment, not a measurement.
Value bet
Definition: A bet where the bettor’s own probability estimate is higher than the probability implied by the odds. With an estimate of 40% and odds of 3.00 (implied 33.33%), the expected return is 0.40 × 3.00 = 1.20 per $1 staked, or +$0.20. The label depends on the estimate being right.
Example: “He called it a value bet at 3.00 because he rated it at 40%.”
A bet labeled value can still lose.
Edge
Definition: A bettor’s estimated advantage on a bet, found by subtracting the implied probability from the estimated probability. An estimate of 40% against an implied 33.33% is an edge of 6.67 percentage points. It is only as reliable as the estimate.
Example: “He thinks he has a seven-point edge.”
Different from the house edge, which belongs to the game.
Arbitrage
Definition: Betting every outcome of one event at prices whose implied probabilities add up to less than 100%, so the same profit is earned whichever outcome occurs. Two outcomes both priced at 2.10 have implied probabilities of 47.62% each, 95.24% in total, and $50 on each returns $105 for $100 staked. Such gaps are rare and short-lived.
Example: “He spotted an arb: both sides were priced at 2.10.”
Often shortened to arb. Differences in rules or settlement can turn it into a loss.
Dutching
Definition: Splitting a total stake across two or more outcomes in one event so that each returns the same amount if it wins. At prices of 3.00 and 6.00, $20 and $10 each return $60. It does not remove risk, because an outcome left uncovered still loses the whole $30.
Example: “He dutched the two leaders so either one returns $60.”
Can reduce the swing in results, not the risk of losing.

Charges, Limits and Cancellations
Some payouts are reduced by a charge, capped by a limit or cancelled altogether.
Commission
Definition: A percentage charge taken from winnings on certain bets. On a baccarat Banker bet the usual commission is 5%, so a winning $100 bet pays $95, which is 0.95 to 1.
Example: “The dealer took the 5% commission from the Banker win.”
The rate varies by game and by venue.
Void bet
Definition: A bet that is cancelled and treated as though it was never placed, so the stake is returned. A bet may be voided when an event is cancelled or a selection is withdrawn, under the terms of the market.
Example: “The match was abandoned, so the bet was void.”
Different from a loss: the stake is not lost.
Payout cap
Definition: A maximum amount that a bet can pay whatever the odds. If a $100 bet at 500.00 would return $50,000 but the cap is $25,000, only $25,000 is paid.
Example: “The payout cap cut the winnings to $25,000.”
Caps vary by market and by rule set.
