FIRE Number Calculator — How Much Do You Need to Never Work Again?

FIRE stands for Financial Independence, Retire Early. It's a lifestyle and financial philosophy where you aggressively save and invest 40–70% of your income to build a corpus large enough that investment returns cover all your living expenses — permanently.

FIRE doesn't necessarily mean stopping work. It means making work optional. Many FIRE adherents continue working on projects they're passionate about, freelancing, or consulting — but without financial pressure.

The FIRE movement in India is growing rapidly, especially among software engineers, doctors, and dual-income households in Tier 1 cities, where high incomes combined with relatively lower lifestyle expenses make early financial independence achievable.

Lean FIRE: Retire on bare minimum expenses (₹25,000–40,000/month in a Tier 2/3 city). Requires a smaller corpus (~₹75 lakh–₹1.2 crore). High frugality required. Common in communities embracing minimalism.

Coast FIRE: Invest aggressively early, then stop contributing. Let the corpus 'coast' to your target through compounding alone. You still work — but only enough to cover current expenses. Example: Invest ₹1 crore by age 35; at 10% return, it becomes ₹6.7 crore by age 60 without adding another rupee.

Fat FIRE: Retire with a large corpus supporting a premium lifestyle (₹2 lakh+/month). Requires ₹6–10+ crore. Common among high-earning professionals with significant savings rates.

Barista FIRE: Retire from high-stress career, do part-time work that covers basic expenses. The invested corpus handles the rest.

Step 1 — Calculate your FIRE number Track monthly expenses × 12 × 25 (or × 30 for safety). Add a 20% buffer for healthcare and lifestyle upgrades.

Step 2 — Calculate your savings rate FIRE timeline depends mostly on savings rate, not income. At 50% savings rate, you can reach FIRE in ~17 years. At 70%, in ~8 years.

Step 3 — Invest in equity-heavy portfolio For 15–20 year FIRE timelines, 80–90% equity (Nifty index funds + flexicap) with 10–20% in EPF/PPF as debt component.

Step 4 — Build passive income streams Rental income, dividends, freelance work — these reduce the corpus needed for FIRE and provide lifestyle inflation buffer.

Step 5 — Track your number quarterly As markets grow, your corpus-to-FIRE-number ratio improves. Most FIRE practitioners declare FIRE when their corpus reaches 90–100% of their FIRE number.
