Retiring at 45: What You Need
Your FIRE number is annual expenses ÷ safe withdrawal rate (e.g. 25× at 4% SWR). For retirement at 45, plan for inflation so your corpus at that age is enough to cover future expenses.
Safe Withdrawal Rate
The 4% rule is widely used; in India many prefer 3–3.5% for more safety. A lower SWR means you need a larger corpus but reduces the risk of running out of money in retirement.
Years to FIRE
The calculator projects your savings and investments forward and finds when your corpus meets the inflation-adjusted amount needed to retire at 45 or earlier.
Frequently Asked Questions
Methodology
How This FIRE Calculator Works
FIRE Number
Your FIRE number is the corpus needed to sustain your expenses using a safe withdrawal rate (SWR):
FIRE Number = Annual Expenses ÷ Safe Withdrawal Rate
For example, at 4% SWR you need 25× your annual expenses (₹12L/year → ₹3 crore).
Inflation Adjustment
Future expenses are projected using your assumed inflation rate: Future expenses (year n) = Current monthly expenses × 12 × (1 + inflation)^n
The corpus needed at retirement uses this inflated expense figure, so you target a higher number the longer your timeline.
Years to FIRE
We project each year:
- Corpus = Future value of current savings + future value of monthly SIP (both at your expected return).
- Required corpus = Inflation-adjusted annual expenses at that year ÷ SWR.
- When corpus ≥ required corpus, you have reached FIRE.
Safe Withdrawal Rate (SWR)
The 4% rule (Bengen study) suggests withdrawing 4% of your corpus annually. For India, many use 3–3.5% for more conservative planning. Lower SWR means you need a larger corpus but more safety.
