    {
      "q": "How does the newsletter sponsorship rate calculator work?",
      "a": "Newsletter ads are priced on CPM against opens, not total subscribers, because an unopened email delivers nothing. Rates of $25–$60 CPM are typical, with niche B2B lists commanding far more. The underlying maths is: Rate = Opens ÷ 1,000 × CPM."

    {
      "q": "What do I need to enter?",
      "a": "5 values: subscribers, open rate, cpm you want to charge, sponsor slots per issue, and issues 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 price per sponsor slot 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."
