Frequently Asked Questions
Everything you need to know about our tax calculator
What is my tax bracket?
Rate on last dollar. 2024 single: 10%/$11.6K, 12%/$47K, 22%/$100K, etc.
Your marginal bracket is the rate on your last dollar of income. In 2024 for single filers: 10% up to $11,600, 12% to $47,150, 22% to $100,525, etc.
What is effective tax rate?
Total tax / total income. Lower than bracket due to progressive rates.
Total tax paid divided by total income. Always lower than marginal bracket because lower brackets apply to initial income. $60K income might have 22% bracket but 12% effective rate.
