How is a parlay payout calculated?

Convert each leg's odds to decimal form, multiply all the decimals together, then multiply by your stake. For example, three legs at -110 each (1.91 decimal) on a $10 stake: 1.91 × 1.91 × 1.91 × $10 = $69.59 total payout, of which $59.59 is profit.

What's the typical payout on a 4-leg $10 parlay at -110?

A 4-leg $10 parlay where every leg is -110 pays $132.83 total ($122.83 profit). All four legs have to win. The implied breakeven win rate per leg is about 52.4%, but because losing any one leg loses the whole ticket, the parlay's combined win probability is only about 7.5%.

Why do parlays have such big payouts?

Because every leg must win, the combined probability shrinks fast — and the payout grows to match. A 5-leg parlay at -110 each has only about a 3.9% chance of cashing, but pays out almost 20-to-1. The big payout is the compensation for the long odds.

How Much Does a $10 Parlay Pay? Reference Tables

It depends on the number of legs and the odds. A $10 parlay with two −110 legs pays $36.45 total ($26.45 profit). A 5-leg version at −110 pays $253.59 ($243.59 profit). Below: the math, plus reference tables for the most common combinations.

The parlay math, in one line

Convert each leg's odds to decimal form, multiply all the decimals together, then multiply by your stake:

Total payout = stake × (leg₁ × leg₂ × … × legₙ)

For three legs at −110 (decimal 1.9091) on $10:

$10 × (1.9091 × 1.9091 × 1.9091) = $10 × 6.9586 = $69.58 total

Profit is total payout minus your stake: $69.58 − $10 = $59.58 profit. (Sportsbooks round slightly differently; some books quote 1.91 instead of 1.9091, which gives $69.68.)

$10 parlay payout at −110 per leg

The most common case — every leg is the standard sportsbook juice line. Decimal odds per leg: 1.9091.

2 legs: $36.45 total ($26.45 profit) — combined ~27.44% win probability
3 legs: $69.58 total ($59.58 profit) — combined ~14.37% win probability
4 legs: $132.83 total ($122.83 profit) — combined ~7.53% win probability
5 legs: $253.59 total ($243.59 profit) — combined ~3.94% win probability
6 legs: $484.13 total ($474.13 profit) — combined ~2.07% win probability
8 legs: $1,764.46 total ($1,754.46 profit) — combined ~0.57% win probability
10 legs: $6,430.82 total ($6,420.82 profit) — combined ~0.16% win probability

5 legs: $976.56 total ($966.56 profit)

Mixed-odds parlays

Real parlays usually have different odds on each leg. The formula is the same — just multiply each leg's decimal odds. For a 4-leg $10 ticket at +200 / −120 / +110 / +180:

3.00 × 1.83 × 2.10 × 2.80 × $10 = $322.81 total ($312.81 profit)

The parlay calculator handles any mix of formats, lets you enter American or decimal or fractional, and shows the combined breakeven win rate so you can compare against your own probability estimates.

A note on the house edge

The vig compounds in a parlay. A 4-leg parlay at −110 each has a true (no-vig) combined probability around 6.25%, but the book pays out at odds that imply about 7.5%. The gap is the parlay-specific hold — typically 25-35% on a 4-leg ticket, far higher than the ~4.76% hold on a single −110 bet.

That doesn't mean parlays are unbeatable. It means each leg has to be a meaningful positive-EV bet on its own to overcome the compounding tax. See Kelly staking for how serious bettors size positive-EV parlays.
