50/30/20 Budget Calculator
The 50/30/20 Budget Calculator splits your take home pay into needs, wants, and savings so you can see a simple budget in seconds. It is built for beginners who have never made a budget before, and it is free to use without an account.
What is the 50/30/20 rule?
A simple budgeting framework that splits after-tax income: 50% needs, 30% wants, 20% savings and debt. It's a starting point — not a law — and works best when you adjust it to your real life.
How it works
You enter your income after taxes and choose whether you are paid weekly, every two weeks, or monthly, and the calculator converts it to a monthly amount. It then shows how much the 50/30/20 rule suggests for each category, and you can enter what you actually spend to see whether each one is on target. If your needs run high, which is common in expensive cities, the result helps you see where a small change would make the biggest difference.
The formula in plain language
Your monthly take home pay is multiplied by 50 percent for needs, 30 percent for wants, and 20 percent for savings and extra debt payments.
A worked example
If you bring home $3,500 a month, the calculator suggests $1,750 for needs such as rent, groceries, and utilities, $1,050 for wants such as dining out and subscriptions, and $700 for savings and extra debt payments.

Frequently Asked Questions
What is the 50/30/20 budget rule?
It's a simple framework that splits your after-tax income three ways: 50% to needs (rent, groceries, insurance, utilities, minimum debt payments), 30% to wants (dining out, subscriptions, hobbies, entertainment), and 20% to savings and debt payoff above the minimums. It was popularized by Senator Elizabeth Warren and is a great starting point for beginners.
What counts as a need vs a want?
A need is something you'd still pay for if your income got cut in half, housing, basic food, utilities, transportation to work, insurance, minimum debt payments. A want is everything else: streaming services, dining out, the nicer apartment, the upgraded phone plan, fitness studio memberships. Be honest. Most people misclassify wants as needs.
What if my needs are more than 50% of my income?
You're not alone, this is very common in high cost-of-living cities. The fix isn't to abandon the framework, it's to use it as a goal. Start with what you can save (even 5%), look for ways to reduce big needs over time (housing, transportation), and increase income where possible. The exact percentages matter less than the habit of tracking and adjusting.
How do I make a budget for beginners?
Write down your monthly take-home pay, list every fixed bill with its due date, then give the rest a job: savings first, then everyday spending. Enter your income above to see a starting 50/30/20 split you can adjust to your real numbers.
