Network Architecture & Subnetting Guide: Parlay Calculator (Sports Betting Odds & Payout Multiplier)
The Parlay Calculator (Sports Betting Odds & Payout Multiplier) provides exact bitmask calculations, CIDR notation analysis, and usable IP address allocations for network engineers and system administrators.
CIDR Subnetting & Address Allocation Rules
IP subnetting divides larger networks into smaller, isolated routing domains to optimize traffic flow and bolster network security. Each subnet is defined by its 32-bit (IPv4) or 128-bit (IPv6) prefix mask.
Our calculator computes network IDs, first/last usable host addresses, and broadcast boundaries instantly with full 32-bit binary representations.

Key Features & Capabilities
- American Odds to Decimal conversion: Positive: $\text{Dec} = 1 + \frac{\text{Odds}}{100}$, Negative: $\text{Dec} = 1 + \frac{100}{|\text{Odds}|}$
- Compound parlay payout formula: $\text{Total Payout} = \text{Stake} \times \prod_{i=1}^n \text{Decimal Odds}_i$
- Same-Game Parlay (SGP) correlation discount and house edge (vigorish / vig) quantification
- Parlay Hedging and Cash-Out value calculator for tickets with remaining active legs
Frequently Asked Questions
How is a multi-leg sports parlay payout calculated?
To calculate a parlay payout, convert all American odds to Decimal odds, multiply the decimal odds of all legs together to find the combined multiplier, and multiply by your stake: Total Payout = Stake × (Decimal 1 × Decimal 2 × ... × Decimal N). For example, a $100 parlay on two standard -110 legs (1.909 × 1.909 = 3.644) returns a total payout of $364.40 ($264.40 net profit).
What happens to a parlay ticket if one game is a push or cancelled?
If one leg of a parlay pushes (ties the spread) or is cancelled/postponed, that specific leg is removed from the parlay and its odds reset to 1.00 (a push). A 3-leg parlay simply reduces to a 2-leg parlay, and payout is recalculated based on the remaining active legs without losing the ticket.
Why do sportsbooks love parlay bets (what is the true house edge)?
On a single standard bet with -110 odds, the sportsbook's house edge (vigorish) is ~4.5%. However, in a parlay, the vigorish compounds multiplicatively across every leg: a 3-leg parlay carries ~13% house edge; a 5-leg parlay carries ~22% house edge; and an 8-leg parlay carries over **35% to 40% house edge**, making parlays the highest-margin product for sportsbooks.
How do you calculate a hedge bet on the final leg of a parlay?
If you have a parlay where all prior legs have won and only one final leg remains, you can guarantee a profit by betting the opposing side of the final game: Hedge Stake = (Total Potential Parlay Payout) / (Decimal Odds of the Opposing Side). This locks in an identical guaranteed net profit regardless of which team wins.
