Retirement Planning: How long will a ₹1 crore retirement fund last? Understand the full calculation..

Retirement Planning: A retirement fund of ₹1 crore seems substantial. But can it cover your expenses for a lifetime? The answer depends on your expenses, inflation, and the returns generated by your investments.

Suppose you have ₹1 crore at the time of retirement. You need to meet your monthly expenses from this fund. In this scenario, simply looking at your current spending isn't enough; you must also account for future inflation.

How long can a ₹1 crore fund last?

Let’s understand this with an example. Suppose your initial monthly expense after retirement is ₹30,000. If your investments yield an average annual return of 8% and inflation remains at 6%, the fund could last for about 40 years.

If your monthly expense is ₹40,000, the fund could last for approximately 27 years. At a monthly expense of ₹50,000, it could last for about 20 years.

Initial Monthly Expense | Fund Duration (Approx.)

₹30,000 | ~40 years
₹40,000 | ~27 years
₹50,000 | ~20 years
₹60,000 | ~16 years

Inflation will increase your expenses.

Ignoring inflation during retirement planning can prove costly. If your monthly expense is ₹40,000 today, that same expense could rise significantly over the next 10 years.

Assuming an inflation rate of 6%, a monthly expense of ₹40,000 today could require approximately ₹71,600 per month in 10 years. This means you shouldn't base your retirement fund calculations solely on current expenses.

Is it right to keep all the money in a Fixed Deposit (FD)?

Parking your entire retirement corpus in a single avenue may not be advisable. Suppose the entire ₹1 crore is invested in an FD. This will generate regular income in the form of interest.

However, rising inflation can erode the real value of that interest. Therefore, it may be necessary to allocate some funds to options that offer the potential for returns exceeding the inflation rate over the long term.

On the other hand, investing the entire corpus in the stock market carries risk. If you need funds during a market downturn, you might be forced to sell your investments at a loss.

How much money should be withdrawn each month?

The '4% withdrawal rule' is a simple strategy for retirement. Under this rule, you can withdraw approximately 4% of your retirement corpus in the first year. In subsequent years, this withdrawal amount is adjusted upwards to account for inflation.

Suppose you have a retirement corpus of ₹1 crore. 4% of this amounts to ₹4 lakh annually, meaning you can initially withdraw around ₹33,300 per month. If inflation is 6%, your withdrawal amount for the following year can be increased by approximately 6%. This ensures that your income keeps pace with rising expenses.

Can a corpus of ₹1 crore last a lifetime?

There is no single answer to this. For one person, a ₹1 crore corpus might last 40 years, while for another, it could be exhausted in 15–20 years.

It depends on your monthly expenses, the inflation rate, and the returns generated by your investments. The higher your expenses, the sooner the corpus will be depleted.
