      "a": "Newsletter economics come down to RPM on the ad side and conversion rate on the paid side. Revenue per subscriber per year is the metric buyers and sponsors both underwrite. The underlying maths is: Ad revenue = Opens ÷ 1,000 × CPM × sends; sub revenue = List × conversion × price."
    },
    {
      "q": "What do I need to enter?",
      "a": "6 values: list size, open rate, sponsored sends per month, sponsor cpm on opens, paid conversion rate, and paid price per month. 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 monthly revenue 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."
