The question nobody asks

If you’ve been anywhere near the Indian investing universe in the past decade, you’ve encountered some version of the great retirement corpus debate. How much do you need? One crore? Two? Five? Calculators multiply, assumptions pile up, and everyone has a number. Some people work backwards from expenses, others from age and life expectancy. But here’s what almost nobody asks: once you have that corpus, however large or small, how exactly do you live on it?

This might sound like a strange question. After all, if you’ve spent 30 years earning a salary, surely you know how to spend money. But spending from a retirement corpus is psychologically different. A salary replenishes itself. Your retirement savings don’t. Every withdrawal feels like you’re eating into your own safety. That’s why many retirees park everything in fixed deposits and try to live only off the interest. It feels responsible and conservative; it feels like you’re preserving your capital.

But what it actually does is guarantee that inflation will slowly erode your standard of living. The returns from pure debt haven’t beaten inflation by much in most years, and in many years, they haven’t beaten it at all. The irony is that the instinct to play it safe after retirement often turns out to be the riskiest decision of all.

Mutual Fund Insight’s December 2025 cover story tackles the question that should matter more than the size of your corpus: how do you manage money after retirement? The mechanics are straightforward, but not intuitive. You can’t eliminate all risk. Trying to do so only transfers the risk from market volatility to the certainty of inflation.

The other uncomfortable truth is that discipline matters more than the starting number. A smaller corpus managed sensibly will outlast a larger corpus spent recklessly. Retirement planning discussions focus obsessively on accumulation targets, as if hitting the magic number solves everything. But we’ve now completed 23 years of publishing this magazine, and the pattern we’ve seen repeatedly is that behaviour after retirement matters as much as the savings before it.

I’ve been writing about retirement for three decades, in my own magazines and elsewhere. Over the years, I have steadfastly pointed out that inflation is the bigger enemy. I did it even back in the day when ‘safe’ fixed-income instruments were the automatic choice. The platforms have changed, the investment options have multiplied, and the calculations have become more sophisticated. The fundamentals haven’t budged.

This is not to say the size of your corpus doesn’t matter. Obviously, it does. But once you’ve retired, that ship has sailed. You cannot go back and save more. You can only work with what you have, which means the crucial question shifts from “how much is enough?” to “how do I make this last?” The answer involves some arithmetic, some asset allocation and a lot of discipline around spending. It’s not exciting. It doesn’t involve timing the market, finding the perfect fund, or optimising your returns. It involves boring basics executed consistently over the course of decades.

As you’ll see in the cover story, the mathematics of retirement aren’t nearly as mysterious as the industry makes them seem. What’s harder is accepting that successful retirement isn’t about hitting a target number and then relaxing. It’s about managing a different kind of financial life, one where your capital has to work for you. The transition requires a shift in thinking, and that shift is what this month’s cover story is designed to help you make.
