Use the free Arbitrage Calculator UK on ToolVexa to split a total stake between two outcomes. Enter the total stake and the two odds, press Calculate, and the stake for each outcome, the guaranteed payout and the guaranteed profit appear straight away.
How to Use
Enter the total amount you want to stake, the odds for outcome A and the odds for outcome B. Press Calculate to see how much to place on each outcome and what the payout and profit would be.
Formula in Plain Words
Take 1 divided by each set of odds to get the implied values, add them, then split the total stake in proportion to those values. Multiply the stake on outcome A by its odds to get the payout, then subtract the total stake to get the profit.
Worked Example
For a total stake of £100 with odds of 2.00 for outcome A and 2.10 for outcome B, the stake on outcome A is £51.22, the stake on outcome B is £48.78 and the guaranteed profit is £2.44. The displayed stakes are rounded, so a hand calculation using the rounded stakes may differ by a penny.
FAQs
What is an arbitrage opportunity?
It is a case where the two sets of odds allow stakes on both outcomes that return more than the total stake, whatever the result.
Do the odds have to be above 1?
Yes. Decimal odds above 1 mean the payout is more than the stake on that outcome.
Is the profit really guaranteed?
Only if both bets are placed at the odds entered and both are accepted. Odds can change, so always check before placing a bet.
