About 50/30/20 Budget Calculator

The 50/30/20 Budget Calculator splits your net monthly paycheck into three balanced buckets: 50% for essential Needs, 30% for discretionary Wants, and 20% for Savings and accelerated Debt Payoff.

Formula & Mathematical Calculation

50% Needs = Net Income × 0.50 (Housing, Utilities, Groceries, Insurance, Minimum Debts)

30% Wants = Net Income × 0.30 (Dining Out, Entertainment, Hobbies, Travel)

20% Savings = Net Income × 0.20 (Emergency Fund, 401k/IRA, Extra Debt Paydown)

Calculation Example

$5,000/Month Net Paycheck: Needs (50%) = $2,500/mo | Wants (30%) = $1,500/mo | Savings (20%) = $1,000/mo ($12,000/year saved!).
