What does this tool do?
The 50/30/20 rule is a starting point: half of take-home pay for needs, 30% for wants and 20% for savings and debt repayment. It is deliberately simple, and it can be adjusted for high-cost cities or aggressive savings goals.
The Formula
Needs = Income × 50%; Wants = Income × 30%; Savings = Income × 20%Frequently Asked Questions
What counts as a need?
Housing, utilities, groceries, insurance, transport to work, minimum debt payments and necessary childcare. A need is something that is difficult to avoid without a major disruption.
Is 20% savings enough?
It is a reasonable baseline. If you started late or have aggressive goals, a higher savings share may be appropriate.
