Budget Calculator

The 50/30/20 rule, popularized by Senator Elizabeth Warren in 'All Your Worth,' divides after-tax income into three categories: 50% for needs (housing, utilities, groceries, minimum debt payments, insurance, transportation), 30% for wants (dining out, entertainment, hobbies, subscriptions, vacations), and 20% for savings and debt repayment (emergency fund, retirement accounts, extra debt paydown). It's a simple starting framework — adjust percentages based on your income level and cost of living. High-cost cities may require 60–70% for needs.

Traditional guidelines recommend spending no more than 28–30% of gross (pre-tax) income on housing costs (rent or mortgage + property tax + insurance). On a $60,000/year ($5,000/month) gross income: 28% = $1,400/month maximum. The newer 'rent burden' threshold is 30% of take-home pay — if rent exceeds this, you're 'cost-burdened.' In expensive cities, many people exceed 30–40%. If housing exceeds 40% of income, prioritize finding lower-cost housing or increasing income before other financial goals.

Personal finance experts generally recommend: 10% minimum savings rate (basic standard). 15–20% good (on track for comfortable retirement at 65–67). 25–30% strong (early retirement possible by 55–60). 40–50%+ FIRE (Financial Independence / Early Retirement) pace. The higher your savings rate, the faster you build financial independence. Savings rate matters more than investment returns — going from 10% to 20% savings rate has a bigger impact than improving investment returns by 2%.

Step 1: Calculate your actual after-tax monthly income. Step 2: Track all current spending for 30 days (most people are surprised — use bank statements). Step 3: Categorize expenses and compare to income. Step 4: Set targets for each category (50/30/20 as a starting point). Step 5: Automate savings — set up automatic transfers to savings/investments on payday, before you spend. Step 6: Review monthly and adjust. The most common budget failure is setting unrealistic restrictions that trigger rebellion. Be honest about your lifestyle and make gradual adjustments.

Financial advisors recommend 3–6 months of essential expenses (not income) in a liquid, accessible account. Essential expenses = housing + food + utilities + minimum debt payments + insurance + basic transportation. If monthly essentials total $3,000, aim for $9,000–$18,000. Build to 3 months first (milestone), then 6 months. Keep emergency funds in a high-yield savings account (HYSA) earning 4–5% interest — don't keep it in a checking account earning 0.01%, and don't invest it in stocks (too volatile for emergency access).
