50/30/20 Budget Calculator
Split take-home pay into 50% needs, 30% wants, and 20% savings. Custom splits, weekly and yearly views, and an actual-vs-plan comparison.
Your take-home income
Use the amount you actually receive after tax and other paycheck deductions. The tool converts it to a monthly equivalent for the breakdown.
Split style
The classic 50/30/20 rule is the starting point. Switch to custom to dial in a split that matches your situation.
Per week, per month, per year
Some bills are weekly, some are monthly, and savings goals are often annual. Use the right column for the time scale you plan against.
| Bucket | Per week | Per month | Per year |
|---|---|---|---|
Needs 50% | $519.23 | $2,250.00 | $27,000.00 |
Wants 30% | $311.54 | $1,350.00 | $16,200.00 |
Savings & debt payoff 20% | $207.69 | $900.00 | $10,800.00 |
Compare to your actual spending (optional)
Enter what you actually spend in a typical month in each bucket. The tool will show how far you are from the plan and what is left over from your income.
Fill in any of the three boxes above to compare actual spending to the plan. Leaving a box blank treats that bucket as zero in the comparison only.
About the rule
The 50/30/20 rule was popularized by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth. It uses three categories instead of a long line-item budget so it is easy to track and easy to keep. Needs covers everything you must pay to live and work: housing, utilities, groceries, transportation to work, health insurance, and minimum debt payments. Wants covers discretionary spending: dining out, hobbies, subscriptions, and travel. Savings includes building an emergency fund, retirement contributions, investing, and any extra debt payoff beyond the minimums. Apply it to take-home pay (the amount that lands in your account after tax and pre-tax deductions), not gross income, so the buckets reflect money you can actually direct.
The rule is a guideline, not a law. In high cost of living areas needs can exceed 50%. When carrying high-interest debt, many financial advisors recommend pushing more into the savings or debt bucket. The custom split lets you model these situations directly.

About this tool
50/30/20 Budget Calculator splits your take-home income into the three buckets popularized by Elizabeth Warren in All Your Worth: 50% for needs (housing, utilities, groceries, transportation to work, minimum debt payments), 30% for wants (dining out, hobbies, subscriptions, travel), and 20% for savings and extra debt payoff (emergency fund, retirement contributions, investments). Enter your take-home pay as monthly, biweekly, weekly, or annual, and the tool normalizes it to a monthly figure. Pick the classic 50/30/20 split or switch to a preset that matches a high cost of living area, a debt payoff push, or a FIRE-style aggressive saver, and you can also enter any custom split that totals 100%. The breakdown shows each bucket per week, per month, and per year, and an optional actual-spending section compares your real spend against the plan and shows what is left over. Eight currencies are supported. All math runs locally; nothing is uploaded.
