Tax Bracket Calculator

Progressive tax systems — used in the US, UK, Canada, Australia, and most of Europe — tax income in layers. In the US for 2024, the first $11,600 of taxable income is taxed at 10%, the next portion up to $47,150 at 12%, then 22% up to $100,525, and so on up to 37% for income above $609,350. A common misconception is that earning $50,000 means paying 22% on the entire amount. In reality, you pay 10% on the first $11,600, 12% on the next $35,550, and 22% only on the remaining $2,850 — giving an effective rate around 13.5%, far less than the marginal rate. This calculator breaks down your tax liability bracket by bracket, showing exactly how much you owe in each tier and your true effective rate. Understanding this distinction helps with financial planning, especially when deciding whether overtime pay or a raise pushes you into a meaningfully higher tax burden (spoiler: it rarely does as dramatically as people fear).

Knowing your marginal bracket — the rate on your next dollar of income — is essential for decisions like contributing to a traditional IRA or 401(k) (which reduces taxable income) versus a Roth account (which uses after-tax dollars but grows tax-free). If you are in the 22% bracket, every $1,000 contributed to a traditional 401(k) saves you $220 in federal taxes that year. For self-employed individuals, this calculator helps estimate quarterly payments by projecting annual income and computing the expected liability. You can also model scenarios: what happens if you earn $10,000 more from a side project, or if you take the standard deduction versus itemizing? All calculations happen in your browser using the official bracket tables, so your income figures stay completely private — important when you are working with real salary data rather than hypothetical numbers.
