      "q": "How does the ev vs gas car cost calculator work?",
      "a": "An EV usually costs less per mile in energy but more up front. The break-even depends almost entirely on your electricity rate and how much you charge at home versus on public DC fast chargers. The underlying maths is: Break-even miles = Price premium ÷ (Gas cost per mile − Electricity cost per mile)."

      "q": "What do I need to enter?",
      "a": "7 values: ev price premium, annual miles, gas car mpg, gas price per gallon, ev efficiency (miles per kwh), electricity price per kwh, and annual maintenance savings on ev. 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 annual savings with the ev result mean?",
      "a": "It is returned as a money amount in US dollars 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."
