50/30/20 Budget Calculator
The 50/30/20 budget calculator translates monthly after-tax income into a simple U.S.
budgeting guideline.
It compares your current needs, wants, and savings or debt repayment against recommended target amounts.
Use it to see which category is over or under the guideline.
| Needs difference | -$100 | Positive means under the 50% target |
|---|---|---|
| Wants difference | $300 | Positive means under the 30% target |
| Savings/debt difference | -$200 | Positive means above the 20% target |
Assumptions
- The 50/30/20 rule is a guideline, not a requirement.
- High-cost U.S. cities may require a different needs percentage.
How this calculator works
Formula used
Recommended needs equal income x 50%, wants equal income x 30%, and savings or debt repayment equals income x 20%.
Example calculation
With $4,000 of monthly after-tax income, the guideline suggests $2,000 for needs, $1,200 for wants, and $800 for savings or debt repayment.
