FAQ

What's the difference between effective and marginal rate?

Your marginal rate is the tax on your last dollar earned; your effective rate is total tax divided by total income — always lower, because early dollars are taxed in lower brackets.

Does this include state tax?

No — this estimates federal income tax only. State income tax varies from 0% (e.g., Texas, Florida) to over 13% (California top rate).
