SIP+SWP: Rs 15,000 monthly SIP for 15 years, and then Rs 70,000 monthly income for decades; how is it possible?

SIP is a method of investing in mutual funds. It allows you to invest in a mutual fund scheme at a regular interval. You can choose a yearly, monthly, or daily SIP to invest in. You don't need a large amount to invest through SIP. It starts with Rs 100, and most mutual funds have Rs 500 as the minimum SIP investment. Even if you invest a small amount for a long period of 15 years and above, the SIP investment can help you generate good returns. SIP works on the rupee cost averaging concept. The price of net asset value (NAV), the basic unit of a mutual fund scheme, keeps changing with the ups and downs of the market. So, you purchase NAV at different rates in different investment periods. It can help beat market volatility in the long run and maximise investments. 

It is opposite to SIP. Here, instead of investing at a prefixed interval, you withdraw money. The only difference is that you invest a lump sum amount in a mutual fund scheme to start SWP. The idea is you get growth on your investment, plus there is already the principal amount. So, one gets the mix of both in the form of a fixed income amount. If your rate of growth is higher than your rate of withdrawal, not only the SWP plan can help you get regular income, but also the value of your fund will grow. SWP is also based on rupee cost averaging basis. Here, the mutual fund house sells your NAV every withdrawal period. So, if the market is high and the cost of NAV is also high, the fund house will sell fewer NAVs for a prefixed amount. 

There can be many ways to build Rs 1 crore corpus, but we will set a target of 16 years. So, the idea is to invest a Rs 15,000 SIP for 16 years and get a 15 per cent annualised return. In equity mutual funds, 12 per cent annualised returns are not tough to get in the long run. But a good mix of mutual funds and reshuffling of non-performing mutual funds can help you generate returns of 15 per cent. 

So, with that strategy, in 16 years, you can generate an estimated corpus of Rs 1,08,26,619 in 16 years, of which Rs 28,80,000 will be your investments and Rs 79,46,619 will be estimated long-term gains. 

You may invest that money in equity, hybrid, and debt funds. But since you need regular income on retirement and may not want to take risk with your money, you can pick a conservative hybrid, balanced hybrid, or a debt fund, where you get at least 8 per cent annualised return.

As per SWP calculator, if you draw Rs 60,000 monthly income with Rs 1,08,26,619 and get 8 per cent annualised return on your investments, then even after withdrawing the same pension for 40 years, or a total withdrawal of 2,88,00,000, you will have the balance worth of Rs 5,19,41,824. 

It means, instead of Rs 60,000, you can go for a higher monthly income, or you can start with Rs 60,000 and increase the monthly income limit as inflation rises.

Given the same condition, if you withdraw Rs 70,000 a month, you can withdraw the amount for 40 years. 

After that period, your total withdrawal will be Rs 3,36,00,000, and the estimated balance worth will be Rs 1,67,99,011.

Even then, your investment can give you Rs 75,000 monthly income for 39 years, and the estimated balance amount after that will be Rs 1,54,732. 

The withdrawal amount after 40 years of Rs 75,000 monthly income for 39 years will be Rs 3,51,00,000.
