How to Use This Calculator
1
Enter your gross annual income
This is your total income before any deductions: wages, salary, freelance, rental income, side income. Don't subtract 401k contributions yet — those come through deductions.
2
Select your filing status
Single, Married Filing Jointly, or Head of Household. Married filing jointly gets nearly double the standard deduction and wider tax brackets — a significant advantage.
3
Choose standard or itemized deductions
Standard deduction 2024: $14,600 (single), $29,200 (married). If your itemized deductions (mortgage interest, charity, medical) total MORE than the standard deduction, choose itemized. Most Americans take the standard.
4
Understand marginal vs effective rate
Marginal rate = the rate on your last dollar of income. Effective rate = what you actually pay as a percentage of total income. Your effective rate is always lower than your marginal rate because lower brackets apply to lower income first.
