Retirement Planning: Can Rs 3,50,000 one-time investment provide Rs 60,000 monthly income for 30 years; know its possibility
Retirement Planning: A one-time investment can grow to a sizeable retirement corpus in the long run. From the same, a person through systematic withdrawal plan (SWP) can withdraw a decent monthly amount for decades. If one gives their investments sufficient time to grow, they may create a corpus from one-time investment of Rs 3,50,000 that may provide them a monthly income of over Rs 60,000 for 30 years.
Retirement Planning, SWP: Want a retirement life where you may not have to depend on others for your expenses? Plan early or have a large amount to invest! The benefit of starting to invest early can make your attempt to create a sizeable retirement corpus much easier compared to a situation when you start to invest late in your life. When you start late, either you have to be very aggressive in your investments, which will be highly risky, or you have to start with a large investment amount. An early start can give your investment years of compounding, helping it grow exponentially in the long run. Even a small investment can generate a corpus that can help you withdraw monthly income for decades. A Rs 3,50,000 one-time investment may provide a retirement corpus that may help you withdraw a monthly amount of over Rs 60,000 for 30 years. Know how it may be possible-

What is retirement corpus required?

What is financially free life?

It's a stage in your retirement when you don't have to earn for your daily expenses. When you have a retirement pool or a source of income from where you get a regular amount for your expenses. If one plans their retirement early in their life, they may achieve financial freedom quite early in their life.
Inflation for retirement corpus

The calculation of a retirement corpus can't be done without considering inflation as a factor. Prices of things increase, and with that, increase your expenses. If you plan to retire after 20 years and expect a retired life for 30 years, you should estimate your expenses from the first to last retirement year. The historical inflation can be taken as a reference when calculating the retirement corpus.
What should be retirement corpus size?

Let's understand it with an example. If you are 30 years old, your current expenses are Rs 40,000 a month, and you plan to retire at 60, then first know the amount you require in the first year of your retirement. Based on that, calculate inflation-adjusted expenses for the expected life. You will get your retirement corpus. Here, it is necessary to know that if you have other financial goals to achieve post retirement, those goals should also be calculated for retirement corpus.

Power of compounding in retirement corpus building

The one who starts to invest early will have more years for compounding of their investments compared to a late beginner. So, an early beginner can achieve financial freedom early in their life, or if they have fixed a retirement age by which they want to regularly invest, they can create a much larger corpus compared to a late starter. Let's see it with an example.
A is 20 years old, and B is 30. Both want to retire at 60 and want to invest Rs 12,000 a month till 60. Each expects a 12 per cent annualised return from their investments. Let's see what corpus they can create.

A will have 40 years to invest; their overall investment in those years will be Rs 57,60,000, estimated capital gains will be Rs 11,17,56,852, and the estimated retirement corpus will be Rs 11,75,16,852.
B will have 30 years to invest; their overall investment in those years will be Rs 43,20,000, estimated capital gains will be Rs 3,26,51,679, and the estimated retirement corpus will be Rs 3,69,71,679.
Here you can see that with a few lakh extra investment amount, A can create over Rs 8 crore extra corpus than B's corpus.
Calculation for story

In our calculation, we will have two phases. In the first phase, we will show how a one-time investment of Rs 3,50,000 will grow in 30 years and how one may withdraw an over Rs 60,000 monthly income from the post-tax corpus for 30 years. So, if a person is 25 years old and invests Rs 3,50,000, and lets it grow until 55 years of age, they may generate an over Rs 60,000 monthly income till 85 years of age.

What will be tax on Rs 1,04,85,973 retirement corpus?

Investment amount for SWP

Post-tax retirement corpus of Rs 92,34,601.375 is the amount that can be used to set up a SWP plan in a mutual fund. Since it's a retirement corpus and one can't take a risk on this amount, it should be invested in a debt or hybrid fund, where the chances of corpus decline are minimum. We will expect a 7 per cent annualised return from this investment.
