The underlying maths is: Brackets are applied progressively; the marginal rate applies only to income above each threshold."

      "q": "What do I need to enter?",
      "a": "3 values: taxable income, filing status, and raise you are considering. Each field starts with a sensible default, so you can change one number at a time and watch the result move."

    {
      "q": "What does the your marginal bracket result mean?",
      "a": "It is returned as a percentage and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds."

    {
      "q": "Is this calculator free, and do I need an account?",
      "a": "Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser."
    },
    {
      "q": "How accurate is the result?",
      "a": "It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them."

    {
      "q": "Who is this tool for?",
      "a": "It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs."
