Mine get around $5 a week (the older two) and in return for this they have to do chores and not fight with each other all the time. The amount can be reduced or taken away altogether depending on behaviour. However they are expected to help clean and tidy the house regardless of pocket money. The chores are more things like unstacking the dishwasher and clearing/cleaning the table after dinner.

They also get a financial reward for going up a level on their readers, or special recognition at school. The amount can vary and they can use it for a lunch order at school or to save. DS1 is currently saving for his own tablet computer so he saves every cent he gets.
