    {
      "q": "How does the rent increase calculator work?",
      "a": "A rent increase only pays off if the tenant stays. One month of vacancy plus turnover costs typically wipes out a 5% raise for the entire year. The underlying maths is: New rent = Current × (1 + increase%); break-even = added annual rent ÷ monthly rent."
    },
    {
      "q": "What do I need to enter?",
      "a": "4 values: current monthly rent, increase, turnover cost if they leave, and vacancy if they leave (months). 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 new monthly rent 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."
