Free 50/30/20 budget calculator — needs, wants, and savings targets from your income, with an optional comparison against what you're actually spending. We checked calculator.net's budget calculator directly and it uses a different 8-category framework, not the widely-known 50/30/20 rule.
How it works
- Enter your after-tax monthly income
- See your target spending for needs (50%), wants (30%), and savings/debt payoff (20%)
- Optionally enter your actual spending in each category to see where you're over or under target
Frequently asked questions
What is the 50/30/20 rule?
A simple budgeting guideline: 50% of after-tax income toward needs (housing, utilities, groceries, minimum debt payments), 30% toward wants (dining out, entertainment, subscriptions), and 20% toward savings and extra debt payoff. We checked calculator.net's budget calculator directly and it uses a different 8-category framework instead of this rule.
Can I compare my actual spending against the targets?
Yes — enter your actual needs/wants/savings totals (comma-separated) and the tool tells you whether each category is over, within, or below target.
