Why This Tool Is Essential

The FIRE (Financial Independence, Retire Early) movement has gained significant traction in India, especially among IT professionals. The core principle: save 50-70% of income, invest aggressively, and build a corpus of 25-30× annual expenses. With India's lower cost of living compared to the West, FIRE is achievable at ₹3-5 crore for many Indians.

Key Features

• FIRE number calculator (25× annual expenses)
• Years to FIRE based on savings rate
• Coast FIRE and Barista FIRE variants
• Safe withdrawal rate analysis
• Lean vs Fat FIRE comparison
• India-specific cost adjustments

Formula & Methodology

FIRE Number = Annual Expenses × 25 (for 4% withdrawal) or × 28.6 (for 3.5%). Years to FIRE = ln[(FI × r + Annual Savings) / Annual Savings] / ln(1 + r).

Step-by-Step Example

Monthly expenses ₹60,000 (₹7.2L/year). FIRE number = ₹7.2L × 25 = ₹1.80 Cr. Saving ₹1L/month at 12% returns: reach FIRE in ~10 years.

Tips for Better Results

• 💡 The 4% rule: withdraw 4% of corpus annually for expenses — corpus should last 30+ years.
• 💡 In India, 3.5% withdrawal rate is safer due to higher inflation.
• 💡 Savings rate matters more than investment returns for reaching FIRE.
• 💡 At 50% savings rate, you can retire in ~17 years; at 70%, in ~8.5 years.
• 💡 Don't forget health insurance — the biggest risk in early retirement is medical expenses.
