      "a": "Between referral fees, payment processing, and shipping, marketplaces routinely take 20–35% of the sale price. Enter your own percentages to see the true net on any platform. The underlying maths is: Net = Price − Platform fee − Payment fee − Shipping − Product cost."

    {
      "q": "What do I need to enter?",
      "a": "6 values: sale price, platform fee, payment processing, flat transaction fee, shipping cost you absorb, and product cost. 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 profit per sale 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."
