There's no specific age at which kids should start learning how to make money, but it's never too early to teach children the value of money and how to manage it. Age-appropriate activities such as allowance, chores, and saving for a desired item can help instill good financial habits and prepare kids for more complex financial decisions as they get older. It's important to consider the individual child's maturity level and ability to understand money concepts when deciding when and how to start teaching financial literacy.
