Budget Calculator: The 50/30/20 Rule
Enter your take-home pay and see how it splits into needs, wants and savings — then compare with what you really spend.
How the Budget Calculator (50/30/20) works
A budget does not have to be a spreadsheet of every coffee. The 50/30/20 rule is a deliberately simple framework: put roughly half of your take-home pay toward needs, about 30% toward wants, and at least 20% toward savings and paying down debt faster than the minimums. This calculator applies that rule to your income, and lets you switch to other popular splits — 60/20/20, 70/20/10 or 40/30/30 — if the classic version does not fit your life.
The comparison section is where the tool becomes useful. Enter what you actually spend in each category and it shows how far you are above or below the suggested amount, both in dollars and as a share of your income. Being over on wants is usually the easiest thing to adjust; being over on needs often points to a bigger decision such as housing costs or a car payment.
If your savings line comes up short, look first for automatic wins: a lower insurance premium, a cheaper phone plan, or one subscription you no longer use. Then pair the budget with a goal. The Emergency Fund Calculator and the Savings Goal Calculator turn the "20%" into a specific target and timeline, which is far more motivating than a percentage.
Remember that percentages are guideposts. A new graduate in an expensive city and a homeowner with a paid-off mortgage will have very different splits, and both can be perfectly healthy. What matters is that your spending is intentional and you are moving toward your goals.
Frequently asked questions
What is the 50/30/20 budget rule?
It splits your after-tax income into three buckets: about 50% for needs, 30% for wants and 20% for savings and extra debt repayment. It was popularized by Elizabeth Warren and Amelia Warren Tyagi as a simple framework for people who do not want to track every transaction.
Should I use gross or take-home income?
Use take-home (after-tax) income — the money that actually lands in your account. Pre-tax retirement contributions deducted from your paycheck can be counted toward your savings bucket if you add them back.
What if my needs are more than 50%?
This is common, especially where housing is expensive. Use the 60/20/20 or 70/20/10 option and see where you land. The goal is to understand where your money goes and shift the split gradually, not to hit exact percentages.
What counts as a need versus a want?
Needs are costs you must pay to live and work: housing, basic food, transportation, insurance, utilities and minimum debt payments. Wants are things you choose: dining out, streaming, upgrades, hobbies and travel. Some items, like groceries, mix both.
