A couple of years ago, someone I had known for a long time passed away. He was just 44. The cause was sudden, the kind that leaves no time for goodbyes, let alone financial arrangements. He had a wife, and a son, – a family that depended on him entirely.
The weeks that followed were disorienting for everyone who knew him. But somewhere beneath the grief, a very practical question began to surface, one that his family had to face whether they were ready to or not.
How long could they sustain that life? And unlike most families where expenses can be trimmed in a crisis, this family’s most significant costs were non-negotiable. The income was gone. The obligations remained. I have thought about that family a great deal since. Not just in sadness, but in the unsettling recognition that what they are facing is a concentrated, accelerated version of a question most of us never properly answer.

Income loss comes in many forms
Every SIP you run, every EMI you service, every insurance premium you pay, every goal you save for. All of it is powered by one thing. The money that lands in your account every month. Take that away, and everything downstream breaks. Not slowly. Suddenly.
And income can stop for more reasons than most of us want to think about.
The death of a primary earner is the most extreme version. But it is not the only one. A cancer diagnosis that sidelines you for two years. A business that fails and takes personal savings with it. A layoff in a restructuring. Financial fraud. A divorce that splits assets and creates new liabilities. Even the slow version counts. An industry that shrinks. Earning power that drops 40% without anyone noticing.
None of these are rare. All of them land on households designed for continuity, for income flowing month after month, indefinitely. The disruption reveals that most of us built for the expected scenario, not the realistic range.
So the question is not whether disruption can happen. It is whether your financial architecture can survive it.
Why income disruption and retirement planning are structurally the same problem?
Most people dramatically underestimate how long their money needs to last. Average life expectancy in India has crossed 71 years. For anyone retiring at 60 in reasonable health, planning to 71 is dangerously optimistic. The realistic planning horizon is 25 to 30 years, and for a couple, it’s longer still.
For a couple at 85, there is a 71% probability that at least one person reaches 85. A 44% probability that at least one reaches 90. That is not a statistical tail risk, that is a near-certain 20 to 25 year financial obligation beyond retirement.
The implication is significant. A couple planning retirement together should plan for the longer of their two life expectancies, not the average, and not the individual. Planning for the average means half the population runs out of money while still alive.
This is why income disruption and retirement planning are structurally the same problem. The question is identical: how does a finite corpus meet rising expenses over a long and uncertain timeline, without being exhausted before the obligation ends?
Then there is inflation
What does inflation actually do to your runway?
Two things are certain in life: death and taxes. What’s less certain is when the first arrives, and how ruinously expensive the wait will be. The assumption that derails most financial plans is treating expenses as roughly stable. They are not. They compound, and they compound faster than most people expect.
At 6% annual inflation, a reasonable baseline for Indian household expenses, your monthly requirement roughly doubles every 12 years. What costs ₹1,50,000 per month today will cost approximately ₹4,81,000 per month in 20 years:
Healthcare is a separate and more severe curve. Hospital services have historically grown far faster than general inflation. In India, medical costs have risen at 12 to 15% annually for years. And critically, healthcare’s share of household spending increases with age: from around 8.6% of income at ages 55-64, rising to over 13.2% at 65 and beyond, and continuing to climb.
They compound faster than almost any other household expense, and they are among the least reducible in a crisis. The practical consequence: the corpus that appears adequate when calculated in today’s rupees may be seriously inadequate in the rupees of 15 or 20 years from now.
The retirement corpus reality check
Assume you are 45 today. You plan to retire at 60. Healthcare and lifestyle inflation runs at 10% annually. The question is not how much you have, it is how much you will need at 60 to sustain your current lifestyle for 30 years:
A ₹5 lakh monthly lifestyle today needs roughly ₹100 crore at the starting line of retirement. Not to grow wealthy. Not to leave a legacy. Just to not run out. The number is achievable. Not through luck or extraordinary returns. Through one variable that most people are squandering every year they wait. Time.
Consider this exercise. Same starting corpus of ₹1 crore. Same target of ₹20 crore. The only thing that changes is when you begin.
Waiting 10 years multiplies the required monthly SIP by 13 times. And the SIP hockey stick below shows why, the last decade of compounding generates more wealth than the first two combined:
Note: This is for illustrative purposes only
The first twenty years of investing build 24% of the final corpus. The last ten years build the remaining 76%. When you delay by a decade, you are not just losing ten years of growth. You are cutting yourself off from the only part of the curve that was going to do the real work.
How to think about your portfolio in a disruption
A portfolio that looks adequate on paper can behave very differently when withdrawals begin early, markets are down, or an unexpected expense lands at the wrong moment.
If your portfolio drops 20% and you simultaneously withdraw 10% — which income disruption forces you to do, you now need a 39% gain just to return to where you started. You have not just lost money. You have permanently shrunk the base from which recovery has to happen.
The instinct is to de-risk, move to fixed income, play it safe. That instinct is historically backwards. Over 90% of portfolio return variability is explained by asset allocation alone, not fund selection or market timing.
Note: This is for illustrative purposes only
Conservative versus Growth: same market, same timeline, three times the outcome.
The person who played it safe did not protect themselves, they chose a different kind of risk. The slow, quiet risk of a corpus that cannot outpace inflation and runs out while they are still alive. For any long-horizon investor, voluntary retirement at 60 or forced disruption at 44, the real risk is not short-term volatility. It is outliving the corpus.
The SRP framework: Three numbers every family should know
Most people ask: ‘Do I have enough?’ But enough for what? Enough for retirement? Enough if something goes wrong? Enough if something goes wrong and I need to protect my family for 40 years? These are different questions. They need different numbers. Here is a cleaner way to think about it, three numbers, each answering a different question:
Where most families actually stand
Based on portfolio reviews at Dezerv, this is what we typically find:
Most families are exposed to all three simultaneously. The Survival Number is dangerously thin. The Replacement Ratio is nowhere near the target. And the Protection gap is large enough that a single event would change the family’s financial trajectory permanently.
Building the Chassis
You cannot prevent income loss. That is often outside your control. But you can build a financial structure strong enough to survive it, a chassis that holds even when the engine fails. Most people over-invest in the engine and under-invest in the chassis. A ₹1.5 crore per year earner with ₹80 lakh in savings and a ₹1.2 crore home loan has a powerful engine on a fragile frame.
One shock and the whole vehicle breaks.
1. Fund your survival number first: 24 months of household expenses in liquid funds and short duration debt. This is not an investment. It is a shock absorber. It buys you time to think clearly instead of selling in panic.
2. Fix your protection number: Pure term insurance. 15 to 20x your annual income. Not ULIPs. Not endowments. It is the cheapest way to ensure the hockey stick survives even if you do not. Add critical illness cover. Being alive but unable to earn for two years is financially more devastating than death.
3. Build your replacement ratio deliberately: Your Replacement Number should climb every year. Dividends, rental yield from REITs, systematic withdrawal plans. The goal is that by 55, your portfolio can generate 70% of your expenses without your salary.
4. Have the conversation with your spouse: Do they know where the assets are? Who is the advisor? Can they access accounts? Is there a documented plan they can follow? This is not glamorous. It is life saving.
5. Diversify your concentration risk: If your income and your largest asset are both tied to the same company, through salary and ESOPs, a single corporate event can destroy both simultaneously. Diversify before the shock. Not after.
In summary
The ₹100 crore retirement number assumes you show up at 60 with a fully funded portfolio. It assumes 15 to 20 years of uninterrupted compounding. It assumes the engine never stalls.
For most of us, that assumption will hold. For some of us, it will not. Nobody knows which group they are in. The goal is not to prevent income loss. That is often outside your control. The goal is to build a financial life that can coast long enough for the engine to restart, or for a new one to take its place. Calculate your three numbers. Fix the gaps while you still have the income to close them. The most important financial skill is getting the goalpost to stop moving. It’s not about earning more.
