Budget Planner Calculator

Build your monthly budget with the 50/30/20 framework — 50% needs, 30% wants, 20% savings — and see how your spending stacks up.

The 50/30/20 rule is the simplest proven budget framework: half your after-tax income for needs (housing, food, transport), 30% for wants (dining, entertainment), and 20% for savings and debt payoff. Enter your income and actual spending to see where you stand.

How it's calculated

The 50/30/20 rule explained

Created by Elizabeth Warren and Amelia Warren Tyagi, the 50/30/20 rule divides your after-tax (take-home) income into three simple buckets. 50% goes to needs — the things you can't easily live without: rent or mortgage, groceries, utilities, transport to work, health insurance, and the minimum payments on your debts. 30% goes to wants — the lifestyle spending you choose: dining out, streaming and other subscriptions, entertainment, shopping, hobbies, and travel. 20% goes to savings and extra debt repayment — your emergency fund, retirement contributions, investments, and any payment above the minimum on high-interest debt.

To apply it, start from your monthly take-home pay, multiply by each percentage to get a target, then total your real spending in each bucket and compare. If a category is over target, the fix is almost always to trim wants first, since needs are hard to change quickly and cutting savings defeats the purpose. The goal isn't perfection in a single month — it's steadily moving your real numbers toward the targets and automating the 20% so it leaves your account before you can spend it.

The percentages are a starting point, not a rule of law. In high cost-of-living areas, needs alone can swallow 60–70% of income. When that happens, don't abandon the framework — rebalance it. Push wants down as far as is realistic and protect whatever savings rate you can, even if it's 10% instead of 20%, while working to raise income over time. A budget you can actually keep beats a perfect one you abandon.

Needs target = Net income × 50% Wants target = Net income × 30% Savings target = Net income × 20% Surplus/deficit per category = Target − Actual spending

Needs
Non-negotiable expenses: housing, food, utilities, transport, minimum debt payments, health insurance.
Wants
Discretionary spending you choose but could reduce: dining, entertainment, shopping, subscriptions, hobbies.
Savings rate
The percentage of your net income that goes to building wealth or reducing debt beyond minimums. Recommended minimum: 20%.
After-tax income
Your take-home pay — what actually lands in your account after income tax and mandatory deductions. The 50/30/20 percentages are always applied to this figure, never to gross pay.
Disclaimer: the 50/30/20 rule is a guideline, not a law. High cost-of-living areas may require adjusting the ratios. Consult a financial planner for personalized advice.

Frequently asked questions

What is the 50/30/20 rule?
The 50/30/20 rule allocates 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment. It was popularized by Elizabeth Warren in "All Your Worth" (2005). It's a starting point — high-cost cities or lower incomes may need different ratios.
Should I use gross or net income?
Always net income (take-home pay after taxes). Gross income inflates your available money — you can't spend what goes to taxes and mandatory deductions.
What if my needs are more than 50%?
Many people in high-cost cities spend 60–70% on needs. This is common and doesn't mean the framework fails — it means you need to reduce wants further to maintain saving, or work toward increasing income. Even saving 10% is meaningful.
Does extra debt payoff count as savings?
Yes. Paying off high-interest debt is the best guaranteed "investment return" you can get. Minimum debt payments are a need; anything extra is counted in the savings bucket.
