Budget Calculator
Quick answer
A budget calculator divides your monthly take-home income into spending categories. Using the 50/30/20 framework, it allocates 50% to needs, 30% to wants, and 20% to savings and debt payoff. Enter your monthly after-tax income and the calculator shows the target dollar amount for each category as a starting point for a realistic budget.
Needs (50%)
—
Housing, food, utilities, minimums
Wants (30%)
—
Dining out, subscriptions, fun
Savings (20%)
—
Savings, extra debt payoff
How to use the 50/30/20 split
The framework divides your take-home pay three ways: half to needs, the essentials you can't skip; just under a third to wants, the discretionary spending that makes life livable; and a fifth to savings and paying down debt faster than the minimums. The calculator turns your income into those three dollar targets so you have concrete numbers to budget against.
Treat it as a starting point
The split is a guideline, not a law of nature. In high-cost areas, needs routinely eat more than half, which squeezes the other two. That's useful information, not a failure: it tells you the meaningful levers are your fixed costs and your income, because there's little fat to trim elsewhere. Adjust the proportions to your reality, and use the framework to spot where your money is actually going versus where you'd like it to.

Frequently asked questions
What is the 50/30/20 budget rule?+
It's a simple framework that splits your after-tax income into 50% for needs (housing, food, utilities, minimum debt payments), 30% for wants, and 20% for savings and extra debt payoff. It's a starting point, not a strict rule, and you can adjust the proportions to fit your situation.
Should I use after-tax or before-tax income for budgeting?+
Use take-home pay, the amount that actually lands in your account after taxes and deductions. Budgeting against gross income overstates what you have to work with and leads to plans that don't survive the month.
What if my needs are more than 50% of my income?+
That's common, especially with high housing costs. Treat the split as a target to work toward rather than a pass/fail test. If needs dominate, the levers are usually increasing income or reducing fixed costs, since wants and savings are already squeezed.
