A parlay odds chart lists the combined price and implied win probability for a given number of equal-priced legs. At the standard price of −110 per leg, a two-leg parlay is about +264, a three-leg parlay about +596 and a four-leg parlay about +1,228. The tables below run from two legs to twelve.
For a real ticket with mixed prices, use the parlay calculator. For the formula behind these numbers, read how to calculate parlay odds.
The values assume the listed odds are multiplied without a same-game correlation adjustment, boost or special payout rule.

Decimal odds are rounded to two places for display; American odds, implied probability and payout are all computed from the unrounded value 1 + 100/110 = 1.909091 and rounded once, at the end. Multiplying the rounded decimal column by your stake can therefore differ by a few cents. Sportsbook display and settlement rounding may differ again.

How to read the chart
- Decimal odds include the returned stake.
- American odds show profit relative to a $100 reference stake.
- Implied probability is
1 ÷ decimal odds. - Total payout includes the original stake.
The probability column is implied by the posted prices. It is not automatically the true probability because sportsbook margin is embedded in each leg.
Why your sportsbook payout may differ
A sportsbook can show a different number because of:
- odds moving between selection and submission;
- mixed prices rather than equal-priced legs;
- same-game correlation adjustments;
- odds boosts or promotional caps;
- alternate-line pricing;
- rounding;
- a voided or pushed leg.
Mixed-leg example
A 3-leg parlay at −110, +125 and −135 has decimal odds of approximately:
1.9091 × 2.2500 × 1.7407 ≈ 7.477
That is roughly +648, with a $10 total payout near $74.77.
