2. How Does the Calculator Work?

The calculator uses the following logic:

Where:

• \( income \) — Your taxable income in USD
• \( tax\_tables \) — IRS tax bracket ranges for different filing statuses
• \( bracket \) — Your marginal tax rate percentage

Explanation: The calculator compares your income against the tax brackets for your filing status to determine which marginal tax rate applies.
