2-Way Arbitrage Betting Calculator

How the Arbitrage Betting Calculator Works :

First, choose your odd format ! The Default is set on Decimal odds (most used).

Second, you can choose if you use :

• – Total stake (accumulated on both bookmakers where you want to place the bets)
• – Or Fixed Stake on Your Main Used Bookmaker (To Avoid Limitations)

Inputs:

Odds 1 & Odds 2: The odds for the two outcomes (e.g., Team A win vs. Team B win) from different bookmakers.

Total Stake: The total amount you want to invest across both bets. Or, if you selected FIXED Stake on the main bookmaker, enter your desired fixed stake. 

Calculations:

Stake 1 & Stake 2: The calculator splits your total stake between the two outcomes using the formula:

Stake 1 = (Total Stake × Odds 2) / (Odds 1 + Odds 2)
Stake 2 = (Total Stake × Odds 1) / (Odds 1 + Odds 2)

Total Payout: The amount you win, which is the same regardless of the outcome (e.g., Stake 1 × Odds 1 or Stake 2 × Odds 2).

Profit: Total Payout - Total Stake.

ROI: Profit as a percentage of your total stake ((Profit / Total Stake) × 100).

Color Coding:

Green: Profit ≥ 0 (arbitrage opportunity exists).

Red: Profit < 0 (no arbitrage; avoid betting).

Example

Odds 1 = 2.0, Odds 2 = 2.1, Total Stake = $100:

Stake 1 = $51.22,Stake2=$48.78

Payout = $102.44 (for either outcome)

Profit = $2.44 (ROI = 2.44%)

Key Notes for Users

Requirements:

Odds must come from different bookmakers.

The formula only works if (1/Odds 1 + 1/Odds 2) < 1 (the calculator does not check this automatically).

Use Case: This tool helps you calculate stakes once you’ve found suitable odds.
