50/30/20 Budget Rule

Finance

Apply the 50/30/20 budgeting rule to your monthly income: 50% to needs, 30% to wants, and 20% to savings. Enter your income to see the recommended amount for each category.

Formula

Needs = Income × 0.50 | Wants = Income × 0.30 | Savings = Income × 0.20
  • The rule divides your after-tax income into three buckets: 50% needs, 30% wants, 20% savings.
  • Needs are essentials — housing, food, utilities, transport, and minimum debt payments.
  • Wants are discretionary spending such as eating out, streaming services, and hobbies.
  • The 20% savings portion builds your emergency fund, retirement, and extra debt payoff.
  • It's a flexible guideline — shift the ratios to match your cost of living and goals.

4,000 monthly income

Inputs
  • Monthly Income: 4000

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

Frequently asked questions

What is the 50/30/20 budget rule?
A simple plan that allocates 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment.
Do I use gross or net income?
Use your take-home pay after taxes, since that's what you actually have to spend and save.
What if I can't hit 20% savings?
Save what you can and build up gradually. Cutting wants or reducing fixed costs frees room to raise your savings rate.
Is this rule right for everyone?
It's a helpful starting point, but people with high debt or expensive housing often need to adjust the percentages.
Where does debt repayment go?
Minimum payments count as needs, while extra payments above the minimum come from the 20% savings/debt bucket.
