What is the Roulette Payout Calculator?

  • Core Functionality
  • Supported Bet Types
  • American vs. European Wheels
The Roulette Payout Calculator is a specialized tool designed to help players instantly determine the potential payout, net winnings, and winning probability for any type of bet in roulette. By simply selecting the type of roulette wheel, the bet type, and the amount wagered, users can get a complete breakdown of what they stand to win. This eliminates guesswork and helps players understand the risk and reward associated with their betting strategy.
Key Features
Our calculator supports both American (with a '0' and '00') and European (with a single '0') roulette wheels, as the number of pockets directly affects the odds and payouts. It covers all standard inside and outside bets, from high-risk, high-reward Straight Up bets to even-money bets like Red/Black or Odd/Even.

Step-by-Step Guide to Using the Calculator

  • Selecting Roulette Type
  • Choosing Your Bet
  • Interpreting the Results
1. Select the Roulette Type
Start by choosing between 'European' and 'American' roulette. The European wheel has 37 pockets (1-36 and a single 0), while the American wheel has 38 pockets (1-36, a 0, and a 00). This choice is crucial as it alters the win probability and the house edge.
2. Choose Your Bet Type
From the dropdown menu, select the bet you are placing. Bets are categorized into 'inside bets' (on specific numbers, like Straight Up, Split, Corner) and 'outside bets' (on groups of numbers, like Column, Dozen, Red/Black).
3. Enter Your Bet Amount
Input the total amount of money you are wagering. The calculator uses this figure to determine the final payout and net winnings.
4. Analyze the Results
After clicking 'Calculate', the tool will display: Total Payout (your stake + profit), Net Winnings (just the profit), Payout Odds (e.g., 35:1), and the Win Probability as a percentage.

Mathematical Derivations and Formulas

  • Calculating Payouts
  • Calculating Win Probability
  • The House Edge Explained
Payout Calculation
The payout is calculated using a simple formula: Payout = Bet Amount × (Payout Odds) + Bet Amount. The 'Payout Odds' are determined by the bet type. For example, a Straight Up bet has odds of 35:1.
Formula: Total Payout = (Bet Amount * (36 / N - 1)) + Bet Amount, where N is the number of squares the bet covers.
Win Probability Calculation
The probability of winning is the number of winning outcomes divided by the total number of possible outcomes.
Formula: Win Probability (%) = (Number of squares covered / Total squares on the wheel) * 100. For a European wheel, the total is 37; for an American wheel, it's 38.
Understanding the House Edge
The house edge is the casino's built-in advantage, which comes from the green '0' and '00' pockets. While the true odds of a Straight Up bet are 36:1 or 37:1, the casino only pays 35:1. This difference is the source of the house edge. For European roulette, the house edge is 2.7%. For American roulette, it's 5.26%.

Calculation Examples

  • Example 1: A $10 Straight Up bet on a European wheel. Probability = (1/37) * 100 ≈ 2.7%. Payout = ($10 * 35) + $10 = $360.
  • Example 2: A $20 Dozen bet on an American wheel. Probability = (12/38) * 100 ≈ 31.58%. Payout = ($20 * 2) + $20 = $60.
