+            What is FIRE? Understanding Financial Independence and Early
+            Retirement
+          </h2>
+          <p className="mb-4 text-lg leading-relaxed">
+            FIRE stands for &quot;Financial Independence, Retire Early.&quot;
+            It&apos;s a movement focused on aggressive saving and strategic
+            investing to build a substantial portfolio. The goal is for
+            investment returns to cover living expenses indefinitely, freeing
+            you from traditional employment. Achieving FIRE means gaining the
+            freedom to pursue passions, travel, or simply enjoy life without
+            needing a regular paycheck. Sound investing advice is crucial for
+            building the wealth needed.
+          </p>
+          <p className="text-lg leading-relaxed">
+            The core principle involves maximizing your savings rate (often
+            50%+) and investing wisely, typically in low-cost, diversified
+            assets like index funds. Your &quot;FIRE number&quot; – the capital
+            needed – is often estimated as 25 times your desired annual
+            spending, derived from the 4% safe withdrawal rate guideline. This
+            FIRE calculator helps you personalize this estimate.

+            How This FIRE Calculator Provides Investing Insights
+          </h2>
+          <p className="mb-4 text-lg leading-relaxed">
+            This calculator helps visualize your path to FIRE by projecting
+            investment growth based on your inputs. Understanding these
+            projections is a key piece of investing advice for long-term
+            planning. Here&apos;s a breakdown of the inputs:
+          </p>
+          <ul className="mb-4 ml-6 list-disc space-y-2 text-lg">
+            <li>
+              <strong>Starting Capital:</strong> The total amount you currently
+              have invested.
+            </li>
+            <li>
+              <strong>Monthly Savings:</strong> The amount you consistently save
+              and invest each month.
+            </li>
+            <li>
+              <strong>Current Age:</strong> Your current age in years.
+            </li>
+            <li>
+              <strong>Expected Annual Growth Rate (%):</strong> The average
+              annual return you expect from your investments (after fees, before
+              inflation).
+            </li>
+            <li>
+              <strong>Desired Monthly Allowance (Today&apos;s Value):</strong>{" "}
+              How much you want to be able to spend each month in retirement, in
+              today&apos;s money value.
+            </li>
+            <li>
+              <strong>Annual Inflation Rate (%):</strong> The expected average

+            </li>
+            <li>
+              <strong>Life Expectancy (Age):</strong> The age until which you
+              want your funds to last.

+          </ul>
+          <p className="text-lg leading-relaxed">
+            The calculator simulates your investment growth year by year,
+            incorporating monthly contributions, the power of compound growth (a
+            core investing principle), and inflation&apos;s impact on your
+            target allowance. It estimates the age at which your capital could
+            sustain your desired, inflation-adjusted monthly spending throughout
+            your expected retirement until your specified life expectancy. It
+            calculates your potential &quot;FIRE Number&quot; and the age you
+            might reach financial independence.
