About Tax Bracket Calculator
This tool demonstrates how progressive tax brackets produce a marginal rate (the rate on your last dollar) and an effective rate (average rate). It’s designed for education and planning. Use official IRS tables for current-year, filing-status-specific brackets, and consult a professional for precise calculations.
