Free Parlay Calculator

A free parlay calculator: enter American odds for each leg, from 2 to 15 legs, and your stake, and it returns the combined odds and the payout.

As a betting odds calculator parlay by parlay, it converts each leg to a multiplier. Positive odds such as +150 become (150/100) + 1, a 2.5 multiplier; negative odds such as -110 become (100/110) + 1, a 1.909 multiplier. Multiply every leg's multiplier together, then by the stake, and that is the payout.

As a parlay payout calculator it also answers the common case directly: with every leg at -110, a 2-leg parlay pays about +260, a 3-leg about +600, a 4-leg about +1200, a 5-leg about +2000 and a 6-leg about +4000, so $10 on five legs returns roughly $210.

If you want the legs chosen for you, the free parlay generator at ghostleg.ai/generator builds signal-weighted parlays from sportsbook vs. Kalshi divergence, sharp money consensus, and CLV analytics, and the GhostLeg Data API at ghostleg.ai/data-api exposes the same intelligence.

Enter American odds for each leg and your stake to get combined odds and payout.

How it works:

Positive odds (+150): (150/100) + 1 = 2.5 multiplier

Negative odds (-110): (100/110) + 1 = 1.909 multiplier Multiply all multipliers together × stake = payout.

Standard payout table (all legs at -110):

2-leg: ~+260, $10 → ~$36

3-leg: ~+600, $10 → ~$70

4-leg: ~+1200, $10 → ~$130

5-leg: ~+2000, $10 → ~$210

6-leg: ~+4000, $10 → ~$410
