Frequently Asked Questions

What is the difference between effective and marginal tax rate?+
Your marginal rate is the bracket your last dollar of income falls into. Your effective rate is the actual percentage of total income paid in tax — always lower than the marginal rate because lower brackets apply to earlier income.
Does this include state taxes?+
No, this calculator estimates federal taxes only. State income tax rates vary widely: from 0% in states like Texas and Florida to over 13% in California. Add your state's rate for a complete picture.
