50/30/20 Budget Calculator (2026)
Enter your monthly take-home pay to see how the popular 50/30/20 rule would split it into needs, wants, and savings. It is a simple starting point for a budget, not a strict rule. Everything runs in your browser; nothing is stored or sent anywhere.
Estimate updates as you type. Needs are 50%, wants are 30%, and savings plus extra debt payments are 20% of take-home pay.
How the 50/30/20 rule works
The 50/30/20 rule is a budgeting framework that divides your monthly after-tax income into three buckets: 50% for needs, 30% for wants, and 20% for savings and extra debt payments. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth. The appeal is simplicity: instead of tracking dozens of categories, you aim for three broad targets.
Needs are the essentials you must pay to live and work — housing, utilities, groceries, basic transportation, insurance, and minimum debt payments. Wants are the discretionary extras like dining out, subscriptions, hobbies, and travel. The final 20% goes toward building savings, an emergency fund, retirement contributions, or paying down debt faster than the minimum.
What this estimate does and does not include
The calculator simply applies the 50, 30, and 20 percent splits to the take-home figure you enter. It does not know your actual bills, so it cannot tell you whether your real spending fits the rule — only what the textbook split would look like. In many high cost of living areas, true needs come to more than half of take-home pay, which is normal and not a failure. Treat the result as a target to compare your real spending against, and adapt the percentages if they do not fit your life.
Common questions
Should I use gross or take-home pay?
Most versions of the rule use take-home pay — your income after taxes and payroll deductions, since that is the money you actually allocate. If retirement or insurance is already deducted from your paycheck, some people add it back and count it under savings or needs. Pick one method and stay consistent.
What if my needs are more than 50%?
That is common, especially where housing is expensive. It is a signal that fixed costs are stretching your budget, not a reason to abandon budgeting. You can adapt the rule — for example 60/20/20 or 70/20/10 — while keeping the habit of saving something every month.
