Free 50/30/20 Budget Calculator
What is a 50/30/20 budget calculator?
The 50/30/20 rule splits take-home pay into three buckets: 50% needs, 30% wants, and 20% savings (including extra debt payoff).
Enter your monthly net income and this calculator shows dollar targets for each bucket — a fast benchmark before you assign categories in Ziko.
50% needs · 30% wants · 20% savings = 100% of take-home pay
Read the full 50/30/20 guide for what counts as a need vs want. Compare your real spending with the 50/30/20 comparison calculator.

How to read your results
- Needs budget (50%) — Housing, utilities, groceries, transport to work, insurance, minimum debt payments.
- Wants (30%) — Dining out, hobbies, premium subscriptions — choices you could cut.
- Savings (20%) — Emergency fund, retirement beyond payroll, sinking funds, extra debt principal.
High-cost city? Needs may run above 50% — use the comparison tool to see gaps, not guilt.
Quick questions
Always net (take-home) pay — what lands in your bank after tax and payroll deductions.
Common with rent or debt. Treat 50/30/20 as a target; trim wants or raise income over time.
If you budget net pay, count payroll retirement in savings or add it back to income for a fuller picture.
