    question: 'What is the main difference between Coast FIRE and Lean FIRE?',
    answer:
      'Coast FIRE focuses on front-loading your savings early so compound interest does the rest—you still work but only to cover current expenses. Lean FIRE means fully retiring but on a minimal budget, typically under $40,000/year.',
  },
  {
    question: 'How do I calculate my Coast FIRE number?',
    answer:
      'Your Coast FIRE number depends on your target retirement age, expected investment returns, and desired retirement spending. Use the formula: Coast Number = Target FIRE Number ÷ (1 + annual return)^(years until traditional retirement). Our calculator handles this automatically.',
  },
  {
    question: 'Is Lean FIRE sustainable long-term?',
    answer:
      'Lean FIRE can be sustainable if you genuinely enjoy a minimalist lifestyle and have low-cost hobbies. However, it has less margin for unexpected expenses like healthcare or inflation spikes. Consider building a buffer or having flexible spending categories.',
  },
  {
    question: 'Can I combine Coast FIRE and Lean FIRE strategies?',
    answer:
      'Absolutely. Many people save aggressively (Lean FIRE mindset) to hit their Coast number early, then switch to a lower-stress job while their investments compound. This hybrid approach offers flexibility and reduced burnout.',
  },
  {
    question: 'Which strategy is better for someone in their 20s?',
    answer:
      'Coast FIRE often works well for young savers because you have decades for compound growth. Save aggressively for 10-15 years, hit your Coast number, then enjoy career flexibility. Lean FIRE might suit those who want to exit the workforce entirely ASAP.',
  },
  {
    question: 'What are the biggest risks of each strategy?',
    answer:
      'Coast FIRE risks include poor market returns during your coasting years or lifestyle inflation. Lean FIRE risks include unexpected expenses, healthcare costs, or finding the frugal lifestyle unsustainable over decades.',
  },

        <h2 className="mt-12">Deep Dive: Coast FIRE</h2>
        <p>
          <strong>Coast FIRE</strong> is about reaching a &quot;tipping point&quot; where you no longer
          need to contribute to your retirement accounts. Your existing investments, left alone to
          compound for 10-20 years, will grow into a full retirement fund.
        </p>
        <p>
          Once you hit your Coast number, you only need to earn enough money to pay your monthly bills.
          This opens the door to:
        </p>
        <ul>
          <li>Switching to a lower-stress job</li>
          <li>Working part-time</li>
          <li>Taking sabbaticals</li>
        </ul>

        <div className="my-8">
          <CoastFireChart />
        </div>

        <h2 className="mt-12">Deep Dive: Lean FIRE</h2>
        <p>
          <strong>Lean FIRE</strong> attacks the equation from the expense side. By drastically lowering
          your cost of living, you lower your required FIRE number.
        </p>
        <p>
          If you can live happily on $35,000 a year, you &quot;only&quot; need $875,000 to retire (based
          on the 4% rule). Compare that to a &quot;Fat FIRE&quot; lifestyle spending $100,000, which
          requires $2.5 million. Lean FIRE is the fastest path out of the workforce, but it requires
          discipline.

        <h2>Run The Numbers</h2>
        <p>The best way to decide is to see the math. Use our calculator to simulate both scenarios:</p>
        <ol>
          <li>
            <strong>For Coast FIRE:</strong> Input your current age and a &quot;Coast Age&quot; (e.g.,
            35). See if your current balance grows enough by age 60 without adding more.
          </li>
          <li>
            <strong>For Lean FIRE:</strong> Lower your &quot;Desired Monthly Allowance&quot; to a
            minimalist level and see how fast you reach freedom.
          </li>
        </ol>

        <h2>Which Should You Choose?</h2>
        <p>
          You don&apos;t have to pick one today. Many people start with a <strong>Lean FIRE</strong>{' '}
          mindset to save aggressively, then transition to <strong>Coast FIRE</strong> once they have a
          safety net, allowing them to enjoy their 30s and 40s more.
        </p>
        <p>
          The most important step is to just <strong>start</strong>.
