Personal Budget Calculator

The 50/30/20 rule is a budgeting guideline that divides after-tax income into three categories: 50% for needs (rent, groceries, utilities, minimum debt payments, insurance), 30% for wants (dining out, entertainment, subscriptions, travel), and 20% for savings and debt repayment above minimums. It's a starting framework, not a law people with high housing costs in expensive cities may find 50% impossible for needs, while people optimizing aggressively for early retirement might target 50% or more for savings. The calculator shows your actual percentages across categories.

The most reliable method is to review the last 2–3 months of bank and credit card statements and categorize every transaction. Most banks and apps offer this automatically. Common findings: subscriptions and streaming services add up faster than expected, dining out is usually the biggest discretionary expense, and 'miscellaneous' categories hide significant spending. The budget calculator lets you enter monthly averages for each category and immediately see where your income is allocated relative to your savings goal.

Financial planners commonly recommend 20% of after-tax income as a savings target (matching the 50/30/20 rule's savings tier). A more aggressive target for early financial independence is 30–50%. The specific percentage that's right for you depends on your age, existing savings, income level, and financial goals. At minimum, contribute enough to your 401(k) to capture any employer match that's an immediate 50–100% return on those dollars. Beyond that, target your emergency fund (3–6 months expenses) before aggressive investing.

Gross income is your salary or wages before any deductions the number on your offer letter or W-2. Take-home pay (net pay) is what actually lands in your bank account after federal income tax withholding, state income tax, FICA (Social Security + Medicare), and any pre-tax deductions like 401(k) contributions and health insurance premiums. For most W-2 employees, take-home is 65–80% of gross. Budget calculators should use take-home pay, not gross this calculator asks for your actual monthly take-home.

For variable or freelance income, budget based on your lowest realistic monthly income rather than your average. This means your expenses can always be covered without cutting back. In higher-income months, the excess goes to a buffer fund (typically 1–2 months of expenses as a cash cushion) and then to savings goals. The income smoothing approach avoids the feast-and-famine cycle where high-income months lead to high spending that can't be maintained in lower-income months.
