Income Breakdown Calculator

Understanding Your Income Breakdown

Knowing where every dollar of your earnings goes is key to financial health. An income breakdown shows the allocation of your gross salary into taxes, deductions, and take-home pay. This calculator visualizes the distribution, helping you understand your net income and plan your budget.

How This Calculator Works

Input your gross annual salary, filing status, state tax rate, and any pre-tax deductions (like 401k or insurance). The calculator computes: Federal tax (progressive brackets), Social Security (6.2% up to wage base), Medicare (1.45%), State tax (flat rate). It then totals deductions and displays your net pay and a donut chart showing percentages of each category.

Formula Explanation

1. Taxable Income = Gross – Pre-Tax Deductions – Standard Deduction (based on filing status).
2. Federal Tax = progressive calculation on taxable income.
3. FICA Taxes: Social Security = 6.2% of gross (up to $176,100), Medicare = 1.45% of gross (plus 0.9% additional over thresholds).
4. State Tax = Gross × state rate (flat).
5. Total Deductions = Federal + Social Security + Medicare + State + Pre-Tax Deductions.
6. Net Pay = Gross – Total Deductions.

Frequently Asked Questions (FAQ)

What is an income breakdown?

An income breakdown shows how your gross earnings are allocated among various categories: federal tax, Social Security, Medicare, state tax, pre-tax deductions, and net take-home pay. It often includes percentages and visual charts like donut graphs.

How is the breakdown calculated?

The calculator uses your inputs to compute each deduction component. It starts with gross salary, subtracts pre-tax deductions, applies tax rates, and totals all withholdings to produce net pay and percentages. The donut chart visually represents the proportion of each category.

What percentage of my income goes to taxes?

It varies based on your income, filing status, state, and deductions. Typically, US workers see 20-35% of gross go to combined federal, state, and FICA taxes. Higher earners pay a larger percentage due to progressive brackets. Use this tool to get your exact breakdown.
