    {
      "q": "How long until I hit a million dollars?",
      "a": "Starting with $50,000 and investing $1,000/month at a 7% average annual return, you'll cross $1 million in about 22.4 years (269 months)."
    },
    {
      "q": "How much does the return rate change the timeline?",
      "a": "At the same contributions, dropping the return from 7% to 5% stretches the timeline by roughly 4-5 years, while pushing it to 9% shaves off a similar amount — return rate compounds heavily over long horizons."
    },
    {
      "q": "Does starting balance matter as much as monthly contributions?",
      "a": "Early on, monthly contributions matter more; later in the timeline, the starting balance's compounding dominates growth, which is why starting to invest even small amounts early has an outsized long-term effect."
    },
    {
      "q": "Is $1 million still 'enough' for retirement?",
      "a": "It depends heavily on withdrawal needs and other income sources — at a 4% withdrawal rate, $1 million supports $40,000/year, which may or may not match your target retirement lifestyle."
