How does this calculator work?
The 50/30/20 rule splits after-tax income into 50% for essential needs, 30% for lifestyle wants, and 20% for savings or debt repayment. Multiply your income by each percentage to get dollar amounts. Adjust the percentages to fit your city and goals — the totals must add to 100%.
Formula
How this is calculated
The 50/30/20 rule, popularised by US Senator Elizabeth Warren in her book "All Your Worth" (2005), divides after-tax income into three broad categories. Needs are non-negotiable fixed or essential expenses — rent or mortgage, groceries, utilities, health insurance and minimum debt repayments. Wants are discretionary spending that improve your lifestyle but could be cut without serious consequence — restaurants, streaming, gym memberships and travel. Savings and debt repayment covers retirement contributions, emergency fund, investment accounts and any extra debt pay-down above the minimum.
The default 50/30/20 split is a guideline, not a law. High-cost cities may push needs above 50%; early savers chasing financial independence often redirect wants to savings. This calculator lets you enter any percentage split that adds to 100%, so you can model a 60/20/20 or 40/30/30 budget just as easily.
All figures are monthly after-tax (take-home) income. If you are paid weekly or bi-weekly, multiply your paycheck by 52 or 26 and divide by 12 to get a monthly equivalent. The calculator shows exact dollar amounts alongside the percentages, making it easy to set concrete spending limits for each category.
Frequently asked questions
Needs are things you genuinely cannot live without: housing, food, essential transport, utilities and insurance. Wants are things you choose to spend on but could reduce — restaurants, subscriptions, hobbies. If you could cancel it without serious harm, it is probably a want.
Yes. The 20% bucket covers both building savings (emergency fund, investments) and paying down debt beyond the minimum payment. Most advisers suggest clearing high-interest debt first before investing.
The 50/30/20 split is a starting point, not a rigid rule. If your essential costs are higher — common in expensive cities — adjust the percentages to reflect reality and focus on gradually reducing needs or increasing income over time.
