How to Use the Parlay Calculator
The Betstamp Parlay Calculator helps you quickly calculate the total payout and odds for any parlay bet. Just input the odds for each leg, and the calculator will do the math — showing your total parlay odds and projected return based on your stake.
Parlays combine multiple bets into one wager, offering a higher potential payout. But there’s a catch: all legs must win for the bet to cash. That risk is what makes parlays appealing — and why payout jumps significantly with each leg you add.
Let’s say you start with a two-leg parlay: Raptors +110 and Yankees +105. If both win, the calculator shows your payout would be roughly +340 odds — meaning you’d profit $340 on a $100 stake. Add a third leg, like Maple Leafs +100, and now your payout jumps to +700 odds. The more you add, the bigger the risk — and the bigger the reward.
Behind the scenes, the math is based on decimal odds. To calculate parlay payouts manually, you’d convert each leg to decimal odds (e.g., +100 becomes 2.0), multiply them together, and convert the result back to American odds. Our calculator does all of that instantly, so you can focus on building your ticket.
Whether you’re creating a weekend long shot or calculating odds for a same-game parlay, this tool makes it easy to visualize the true value of your parlay before locking in your bet.
