Split your monthly income into needs, wants, and savings using the popular 50/30/20 budgeting rule. Enter your income and instantly see how much to allocate to each category.

Formula

Needs: 50% | Wants: 30% | Savings: 20%
  • The 50/30/20 rule is a simple framework for after-tax income: half to needs, a third to wants, a fifth to savings.
  • Needs are essentials you can't skip — rent, utilities, groceries, minimum debt payments.
  • Wants are lifestyle spending such as dining out, subscriptions, and hobbies.
  • The 20% savings slice covers emergency funds, retirement, and extra debt repayment.
  • Treat the split as a guideline; adjust the percentages to fit your own goals and cost of living.

Inputs
  • Monthly Income: 4000

With 4,000 income: needs = 2,000 (50%), wants = 1,200 (30%), and savings = 800 (20%).

Frequently asked questions

What is the 50/30/20 rule?
It's a budgeting guideline that allocates 50% of your after-tax income to needs, 30% to wants, and 20% to savings and debt repayment.
Should I use gross or net income?
Use your take-home (after-tax) income, since that's the money you actually have available to budget.
What counts as a need versus a want?
Needs are essentials you can't avoid (housing, food, utilities); wants are discretionary (entertainment, dining out, upgrades).
What if my needs exceed 50%?
That's common in high-cost areas. Trim wants and savings temporarily, and look for ways to lower fixed costs over time.
Is the 50/30/20 split mandatory?
No. It's a starting point. Many people adjust it — for example saving more aggressively — to match their priorities.
