Set a fair weekly allowance for kids by age.
The most widely used allowance rule is a fixed amount per year of age per week — a dollar a year is the classic version, so a ten-year-old gets ten dollars. It works because it scales automatically as the child grows and needs more spending money, and it removes the annual negotiation. Splitting the amount into a spendable share and a mandatory savings share is what turns pocket money into a teaching tool: the child learns to plan around a smaller weekly figure while watching a balance grow. A chore bonus kept separate from the base amount is deliberate — it distinguishes money given as a share of the household from money earned by contributing to it.
Allowance
Weekly allowance = age x amount per year of age + chore bonus; savings portion = allowance x savings share%; monthly cost = allowance x 4.345
Around 10 dollars a week using the dollar-per-year rule, or 5 to 15 depending on what it is expected to cover. What matters more than the amount is that the boundaries are clear.
Most family finance educators suggest a base allowance that is unconditional plus a bonus for extra work. That way basic household contribution is an expectation, not a transaction.
