50/30/20 Budget Calculator
Split your income into needs, wants and savings with the 50/30/20 rule.
The 50/30/20 rule is the simplest budgeting framework that actually sticks: spend 50% of your after-tax income on needs, 30% on wants, and put 20% toward savings and debt repayment. Its appeal is that it's memorable and flexible — three buckets instead of tracking forty categories.
Enter your monthly take-home income and this calculator splits it into the three buckets, giving you concrete target amounts. Treat the percentages as a starting point to adjust for your situation — high earners often save more than 20%, while those in expensive cities may need over 50% for essentials.
