🔥 What is FIRE?

FIRE (Financial Independence, Retire Early) is a lifestyle movement focused on aggressive saving and investing to retire far earlier than the traditional age of 60. The goal is to accumulate a corpus large enough that investment returns cover all living expenses indefinitely.

Example: Monthly expenses ₹80,000 → Annual ₹9.6L → Inflation-adjusted at retirement ₹23.0L (15 yrs, 6%) → FIRE Corpus at 4% SWR = ₹5.75 crore

Use our Inflation Calculator to understand how rising costs affect your FIRE number.

How the FIRE Number is Calculated

📐 FIRE Formula & Assumptions

This calculator uses the inflation-adjusted SWR approach — the most conservative and widely accepted methodology for FIRE planning. For contribution planning, pair this with our SIP Calculator and Retirement Calculator.

Step 1 – Inflation-adjust expenses to retirement year:

Annual Expense at Retirement = Current Annual Expense × (1 + Inflation)years

Step 2 – Calculate FIRE Corpus (SWR method):

FIRE Corpus = Inflation-Adjusted Annual Expense ÷ Safe Withdrawal Rate

At 4% SWR: Multiply annual expense by 25

Step 3 – Check if savings can reach it:

Projected Corpus = FV of Current Savings + FV of Monthly SIP at pre-retirement return rate

  • FV of lump sum = Current Savings × (1 + Return)Years
  • FV of SIP = Monthly SIP × [((1 + r/12)n − 1) / (r/12)] × (1 + r/12)
  • Compare projected corpus vs FIRE corpus to check gap or surplus

Types of FIRE — Which One Is Right for You?

🌿

Lean FIRE

Retire with minimal spending — a frugal lifestyle, often in a lower cost-of-living city or region.

  • Monthly spend: ₹30,000–₹50,000
  • FIRE corpus: ~₹1–1.5 crore
  • Requires strict budget discipline
  • Best for: solo individuals, minimalists
🔥

Regular FIRE

The standard FIRE — retire comfortably without luxury, covering all typical expenses.

  • Monthly spend: ₹75,000–₹1.5L
  • FIRE corpus: ~₹2.5–5 crore
  • Flexible but disciplined
  • Best for: urban families with one income
💰

Fat FIRE

Retire rich — maintain an affluent lifestyle with travel, luxury, and generosity in retirement.

  • Monthly spend: ₹2L+
  • FIRE corpus: ₹8–15 crore+
  • Requires very high savings rate
  • Best for: high earners in IT/finance
🧑‍💼

Barista FIRE / Coast FIRE

Semi-retirement: stop investing, let compound interest do the work, work part-time for expenses.

  • Coast FIRE: reach corpus that will grow to FIRE number by itself
  • Barista FIRE: semi-retire to low-stress work covering monthly expenses
  • Reduces pressure, preserves flexibility

Is the 4% Rule (SWR) Valid in India?

The 4% Safe Withdrawal Rate (SWR) was derived from US historical data (1926–1995) by the Trinity Study. It means withdrawing 4% of your corpus per year, adjusted for inflation, should last 30 years.

Factor US Context India Context
Historical equity return ~10% nominal ~12% nominal (Nifty 50 TRI)
Historical inflation ~3% average ~6–7% average
Real return ~7% ~5–6%
Safe withdrawal rate 4% (25× rule) 3–3.5% (28–33× rule) recommended
Currency risk Low Moderate (INR depreciation)

💡 Recommendation for Indian FIRE: Use 3.5% SWR (28× expenses) for early retirement below age 45, and 4% (25×) for retirement after 50.

⚠️

Common FIRE Mistakes in India

  • Underestimating inflation over 30+ years
  • Not accounting for healthcare costs post-retirement
  • Using pre-retirement returns for post-retirement phase
  • Ignoring sequence-of-returns risk in early retirement years
  • No tax planning (LTCG, dividend tax) on corpus withdrawals
🎯

FIRE Savings Rate Guide

Your savings rate determines how quickly you reach FIRE.

  • 10% savings: ~40+ years to FIRE
  • 25% savings: ~30 years to FIRE
  • 50% savings: ~17 years to FIRE
  • 65% savings: ~10 years to FIRE
  • 75% savings: ~7 years to FIRE

Assuming 7% real return and 4% SWR.

Frequently Asked Questions

What is FIRE corpus?

FIRE corpus is the total amount required so that withdrawals from your investments can cover your retirement expenses.

Why is inflation included?

Your expenses rise over time. The calculator inflates your current monthly expense to estimate your expense at target FIRE age.

What is the 25x rule?

The 25x rule means you need about 25 times your annual expense for a 4% withdrawal strategy.

Why does this calculator not ask SIP or current corpus?

This tool is purposefully simple and only answers "how much corpus is needed". Use the Retirement Calculator to estimate required SIP.

What is Coast FIRE here?

Coast FIRE is the corpus needed today such that it grows to your regular FIRE corpus by your target age at an assumed 10% return.

Is FIRE realistic in India?

Yes, FIRE is realistic in India with disciplined saving, long-term investing, and realistic expense assumptions. Because inflation can stay high, many people plan with a safer 28x to 33x multiple instead of just 25x.

How much salary is needed for FIRE?

There is no fixed salary requirement. What matters most is your savings rate and lifestyle cost. A higher income helps only if a large share is invested consistently toward your target corpus.

Can I retire at 40 in India?

Yes, it is possible, but you need a larger corpus buffer because retirement duration is longer. Plan conservatively, include healthcare and inflation, and prefer a safer withdrawal approach such as 3% to 3.5%.
