What is FIRE (Financial Independence, Retire Early)?

FIRE in India is fundamentally different from FIRE in the US. While the core concept—saving and investing aggressively to retire a decade or more ahead of schedule—remains the same, the assumptions used require careful adjustment for the Indian context.

A standard FIRE calculator helps you determine your retirement corpus—the exact absolute number of investments you need to sustain your lifestyle indefinitely without relying on active income. Once you reach this financial independence milestone, work becomes a choice, not a necessity.

How this early retirement calculator works

Unlike generic retirement calculators that assume flat withdrawal rates, this tool models two distinct mathematical realities. It dynamically calculates both the global standard (the 4% rule) and the designated safe withdrawal rate for India (the 3% rule) in parallel.

By inputting your current monthly expenses, expected inflation, and expected portfolio returns, this calculator mathematically projects your required retirement corpus across decades. It then backward-calculates the exact monthly SIP needed to bridge the gap and securely hit your FIRE number.

The math behind your FIRE number

FIRE planning involves three sequential calculations: inflating your expenses to retirement date, applying a safe withdrawal rate to find your target corpus, then back-calculating the SIP needed.

Step 1Future annual expenses at retirement

Future Exp = Current Annual Exp × (1 + inflation)^years

Your Rs.6L/year today costs Rs.25.75L/year after 25 years at 6% inflation.

Step 2FIRE corpus (safe withdrawal rate)

FIRE Number = Future Annual Expenses / withdrawal rate

4% rule: FIRE = expenses / 0.04 = 25x expenses. India-safe 3% rule: FIRE = expenses / 0.03 = 33x expenses.

Step 3Monthly SIP to reach FIRE (reverse SIP formula)

P = FV * r / (((1+r)^n - 1) * (1+r))

r = annual return / 12 / 100 (monthly rate), n = years * 12 (total months). Standard Indian SIP formula inverted.

Worked example

Inputs: Age 30 → retire at 55 · ₹50,000/month expenses · 6% inflation · 12% returns · ₹0 savings

Future Exp6,00,000 × (1.06)^25 = 6,00,000 × 4.292= ₹25,75,000/year
FIRE (4%)25,75,000 ÷ 0.04= ₹6.44 Cr
FIRE (3%)25,75,000 ÷ 0.03= ₹8.58 Cr
SIP neededReverse SIP · r=1%/mo, n=300 months, target=₹8.58 Cr≈ ₹45,200/month

India note: The 4% rule was derived from US market data. With India's higher structural inflation and shorter equity market history, using 3% (33× expenses) gives a meaningful safety margin. We show you both — you decide.
