The Budget Calculator organizes your monthly income and expenses using the proven 50/30/20 budgeting rule and custom budget allocation frameworks.
Under the 50/30/20 framework popularized by personal finance experts, after-tax net income is divided into three primary categories: 50% for Needs (rent/mortgage, utilities, groceries, healthcare, minimum debt service), 30% for Wants (dining out, entertainment, hobbies, travel), and 20% for Savings and Extra Debt Elimination (emergency fund, retirement contributions, index funds).
All budget structuring runs locally in your browser session. Your income figures, expense line items, and financial summaries are never uploaded or saved to any server.

Needs = Net Income * 0.50 | Wants = Net Income * 0.30 | Savings = Net Income * 0.20Net Income is monthly after-tax pay. Needs comprise essential housing, utilities, groceries, and insurance. Wants comprise discretionary leisure. Savings comprise investments and extra debt principal.
Monthly Take-Home Pay = $4,500.00 Target Needs (50%) = $4,500 * 0.50 = $2,250.00 Target Wants (30%) = $4,500 * 0.30 = $1,350.00 Target Savings & Debt Payoff (20%) = $4,500 * 0.20 = $900.00.
