Hello everyone,
I've been trying to improve my excel sheets lately and add a bit automation to them, however I am stacked with the math formula to get the match percentage.

Example:
Odd 1: 2.00 vs Odd 2: 2.10
Percentage is 2.44% according to: https://www.betburger.com/surebet-calculator

Anyone know the math formula behind this 2.44%?

Thank you

hey Downbreak, it's odds_1 * odds_2 / (odds_1 + odds_2) -1

however instead of just copying I suggest you try to break down what placing a surebet means: you bet an amount X on first leg, then you bet the amount on second leg that matches your "to win" amount on first leg, and from those numbers you can easily calculate the match percentage (net amount you win divided by total amount you bet)

good luck

Thanks for your reply @barbero. So according to my example it would be:
2.00x2.10/(2.00+2.10)-1 which turns 0.02439 and then i just multiply by 100 to get the almost 2.44%, right?

Right, well, 0.0244 is in fact 2.44%. Yes, your calculation is correct.
