The 50/30/20 Rule: Budgeting & Saving
The 50/30/20 rule is a simple budgeting framework: spend about 50% of after-tax income on needs, 30% on wants, and 20% on savings and debt repayment. This lesson teaches students how to sort spending into the three buckets and adapt the rule to their own situation.
