Calculation method

The 50/30/20 budgeting rule divides your monthly after-tax income into three buckets: 50% for needs (rent, groceries, utilities, transport, insurance, minimum debt), 30% for wants (dining out, hobbies, streaming, travel), and 20% for savings & extra debt payments. The math is simply income × 0.50, × 0.30, and × 0.20.
