1. Convert all odds to decimal format (follow the steps in this post or use my Odds Converter)
2. Multiply together each of the decimal odds
3. The final product represents the true parlay odds (in decimal form)

Example: What are the true parlay odds when parlaying a line of -800 with a line of -600?

-800 in decimal odds form = 1 + 100/800 = 1.1250
-600 in decimal odds form = 1 + 100/600 ≈ 1.1667

True parlay odds = 1.1250 × 1.1667 = 1.3125

1.3125 in US odds form = -100 / (1.3125-1) = -320
