How much money do I need to retire?

The standard starting estimate is 25 times your annual expenses — derived from the idea that withdrawing about 4% of a diversified portfolio annually has historically been sustainable over a 30-year retirement. So if you need ₹10 lakh a year, the target is roughly ₹2.5 crore in today's money. **Why expenses rather than income**: what matters is what you spend, not what you earn. Someone earning a lot and spending modestly needs a much smaller portfolio than the reverse, which is why the savings rate is the dominant variable. **Adjustments to the basic number:** - **Retiring early** (before the usual age) means a longer retirement, so a lower withdrawal rate — closer to 3.5% — is prudent, raising the multiple to around 28-30x. - **Other income sources** — a pension, rental income, part-time work, state benefits — reduce the portfolio you need. Subtract that income from your annual expenses before multiplying. - **Healthcare** typically rises with age and is the largest uncertainty in most plans. Budget generously. - **Inflation.** The 4% guideline already assumes inflation-adjusted withdrawals, but your target should be calculated in today's money and revisited periodically. **The honest caveats about the 4% rule**: it comes from historical data in specific markets over specific periods, and it's a starting point rather than a law. Sequence risk — a large market fall in your first few retirement years — is the main danger, and flexibility (reducing spending in bad years) improves outcomes substantially. Most retirees don't withdraw mechanically; they adjust. **What actually determines whether you get there:** 1. **Savings rate**, by a wide margin. The relationship is steep: saving 10% takes roughly 40+ years to reach independence, 25% takes about 30, 50% takes around 15. 2. **Time**, because of compounding. 3. **Costs**, since fees compound against you. 4. **Not interrupting it** — selling in downturns is what breaks plans. **If the number feels impossible**: it usually looks that way at the start, because compounding does most of the work in the final third. Run a compound growth calculation with your actual monthly amount over the actual years — most people find the result substantially less frightening than the headline figure, and the exercise turns a vague dread into a plan you can adjust.
