To calculate the FA Cup betting odds, use this tip: if they are decimal odds, multiply your stake by them to determine the potential return. Here’s an example: a NZ$10 bet at odds of 2.0 yields a NZ$20 return.
For fractional odds, consider the first number the number you’ll multiply your initial stake by. For example, 4/1 fractional odds will win you NZ$4 for every NZ$1 wagered.
