How Much Do You Actually Need to Retire?

Why "a big round number" isn't a real plan

"I need ₹5 crore to retire" is a common sentiment, but without connecting it to your actual expenses, inflation, and retirement length, it's just a guess - it could be wildly too much or too little depending on your real situation.

A more grounded approach

1. Estimate your current annual expenses - the amount you actually need to live on today, not your current income (some of your income today goes to things that stop at retirement, like loan EMIs that may be paid off, or saving itself).
2. Project that forward with inflation to the year you plan to retire. Even a modest inflation rate compounds significantly over 20-30 working years - ₹50,000/month today becomes a considerably larger number by the time you're 60, purely from inflation, before your lifestyle even changes.
3. Decide how many years of retirement you're planning for. With rising life expectancy, planning for a 25-30 year retirement (not just 10-15) is increasingly the more realistic assumption.
4. Size a corpus that can sustain inflated annual expenses for that many years, ideally continuing to grow at a modest rate even while you're withdrawing from it (a corpus sitting in cash, doing nothing, gets eroded by inflation even during retirement).

Why starting this calculation early changes the outcome

The gap between "I'll figure out retirement later" and "I calculated a real number at 30 and started investing toward it" compounds dramatically over decades - see our article on SIPs and compounding for why the earlier the start, the smaller the required monthly contribution to hit the same eventual target.

A common blind spot: healthcare costs

Healthcare expenses tend to rise faster than general inflation, and tend to increase with age - a retirement plan that only projects today's routine expenses forward, without a separate, generous allowance for healthcare, often understates the real number needed.

The takeaway

Replace "a big round number" with your own real numbers - current expenses, years to retirement, expected retirement length, and inflation - even a rough version of this calculation beats no calculation at all.
