-FIRE calculator
+# InvestingFIRE 🔥 — The #1 Interactive FIRE Calculator
+
+**InvestingFIRE** is a responsive web application for calculating your path to Financial Independence and Early Retirement (FIRE). It features a year-by-year projection engine that simulates both accumulation (savings and investment growth) and retirement (withdrawals) phases, allowing users to:
+
+- Input starting capital, monthly savings, expected annual growth rate, inflation rate, current age, desired retirement age, life expectancy, and desired monthly retirement allowance.
+- View a dynamic chart displaying projected portfolio balance and monthly allowance over time.
+- Instantly see their estimated “FIRE number” (required capital at retirement), how long their capital will last, and compare results to the “4% rule.”
+- Adjust assumptions live, with all calculations and visualizations updating automatically.
+- Access explanatory content about FIRE methodology, key variables, and additional community resources, all on a single, consolidated page.
+
+The project’s code is structured using React/Next.js with TypeScript, focusing on user experience, modern UI components, and clarity of financial assumptions.
+
+---
+
+## 🚀 Features at a Glance
+
+- **⚡️ Real-Time Projections:** Every field updates the chart _as you type_. Experiment with savings, growth rates, inflation, or retirement age and see your future instantly.
+- **📈 Interactive Chart:** Dual-area plots for portfolio value and future monthly spending, plus reference lines for FIRE milestones and “4% rule” legends.
+- **🧠 Education Baked In:** Contextual tooltips, deep-dive sections on how FIRE works, FAQs, and must-read resources included.
+- **🔎 Detailed Methodology:** Not just a 25x rule — runs a full, year-by-year simulation with inflation-adjusted withdrawals and optional 4%-rule overlays.
+- **👌 Modern UX:** Typing, sliding, or clicking feels _good_. Responsive on all devices.
+
+---
+
+## 🧰 How It Works
+
+The calculator models your FIRE journey in two phases:
+
+1. **Accumulation:**
+   - Your starting capital is grown by your expected CAGR (~7% by default).
+   - Monthly savings are added for each year until retirement.
+   - Every variable can be adjusted live (capital, savings, age, growth, inflation, spending, target retirement).
+
+2. **Retirement:**
+   - Your balance continues to grow by CAGR.
+   - Each year, an inflation-adjusted monthly allowance is withdrawn.
+   - The simulation runs until your selected life expectancy, showing the possibility of portfolio depletion.
+
+**Key Outputs:**
+
+- 🔥 “FIRE Number”: Portfolio value at your defined retirement age
+- 📊 Interactive projection chart: See how your nest egg and withdrawals evolve over time
+- 4️⃣ “4% Rule” overlays: Compare dynamic results to classic rule-of-thumb
+
+---
+
+## 🌟 Try It For Yourself
+
+To run locally:
+
+1. **Clone the repo**
+   ```bash
+   git clone https://git.schulze.network/schulze/fire.git
+   cd fire
+   ```
+2. **Install dependencies**
+   ```bash
+   pnpm install
+   ```
+3. **Run the app**
+   ```bash
+   pnpm run dev
+   ```
+4. Visit [http://localhost:3000](http://localhost:3000) and unleash the fire.

+
+## ✏️ Inputs & Variables
+
+- **Starting Capital** — How much you’ve already invested
+- **Monthly Savings** — What you’ll add each month
+- **Current Age & Retirement Age** — Your FI timeline
+- **Life Expectancy** — How long do you want income to last?
+- **Expected Growth Rate (CAGR)** — Portfolio annual % return, before inflation
+- **Inflation Rate** — Cost of living increases
+- **Desired Monthly Allowance** — Your lifestyle, today’s dollars
+
+As you adjust these, all projections update instantly _without needing to hit “Calculate.”_
+
+Try many “what ifs” fast.

-            FIRE stands for &quot;Financial Independence, Retire Early.&quot;
-            It&apos;s a movement focused on aggressive saving and investing to
-            build a large enough portfolio that the returns can cover living
-            expenses indefinitely. Achieving FIRE means you are no longer
-            dependent on traditional employment to fund your lifestyle, giving
-            you the freedom to pursue passions, travel, or simply enjoy life
-            without the need for a regular paycheck.
-          </p>
-          <p className="text-lg leading-relaxed">
-            The core principle often involves saving a high percentage of income
-            (sometimes 50% or more) and investing it wisely, typically in
-            low-cost index funds. The target amount, often called the &quot;FIRE
-            number,&quot; is usually calculated as 25 times your desired annual
-            spending, based on the 4% safe withdrawal rate rule.

-            The calculator simulates your investment growth year by year,

-            the age at which your accumulated capital is sufficient to sustain
-            your desired, inflation-adjusted monthly allowance throughout your
-            expected retirement years until your specified life expectancy. It

-                What is the 4% rule?

               <AccordionContent className="text-lg leading-relaxed">
-                The 4% rule is a guideline suggesting that you can safely
-                withdraw 4% of your investment portfolio&apos;s value in your
-                first year of retirement, and then adjust that amount for
-                inflation each subsequent year, with a high probability of your
-                money lasting for at least 30 years. This calculator uses a more
-                dynamic simulation based on your life expectancy but is related
-                to this concept.
+                We run a multi-year projection in two phases:
+                <ol className="ml-6 list-decimal space-y-1">
+                  <li>
+                    <strong>Accumulation:</strong> Your balance grows by CAGR
+                    and you add monthly savings.
+                  </li>
+                  <li>
+                    <strong>Retirement:</strong> The balance continues
+                    compounding, but you withdraw an inflation-adjusted monthly
+                    allowance.
+                  </li>
+                </ol>
+                The result: a precise estimate of the capital you&apos;ll have
+                at retirement (your “FIRE Number”) and how long it will last
+                until your chosen life expectancy.

-                Historically, diversified stock market investments have returned
-                around 7-10% annually over the long term, before inflation. A
-                rate of 7% (after fees) is often used as a reasonable estimate,
-                but past performance doesn&apos;t guarantee future results.
-                It&apos;s crucial to choose a rate you feel comfortable with and
-                understand the associated risks.
+                The 4% rule is a useful starting point (25× annual spending),
+                but it assumes a fixed withdrawal rate with inflation
+                adjustments and doesn&apos;t model ongoing savings or dynamic
+                market returns. Our calculator simulates each year&apos;s
+                growth, contributions, and inflation-indexed withdrawals to give
+                you a tailored picture.

-                Inflation erodes the purchasing power of money over time. Your

-                supports your desired lifestyle in future dollars.
+                Historically, a diversified portfolio of equities and bonds has
