Discipline determines the size of your retirement corpus

I am working with a financial planner, and they did some math to make sense of my current portfolio’s value. I knew how many rupees my portfolio was worth, but I didn’t know how many of my financial goals this money was good for. The planner’s way of looking at the corpus gave me a fresh look at the portfolio.

Let’s say the value of my current corpus is X. In about 21 years, I need a retirement corpus that’s at least as large as 3X. Assuming an average annual return of 10%, my existing corpus will double in about 7 years. If I left this corpus of X untouched for 21 years, I’ll have 8X by the time I retire! Such a corpus will be sufficiently large for the kind of retirement I want to have: the kind where I am free to travel, have sufficient buffer for unexpected emergencies, generously spend on life events of children and grandchildren, etc.

While this corpus grows in the background, I’ll also be making fresh investments in the next 21 years. All the new investments that I’ll be making towards retirement in the next 21 years will only grow to X. It’s almost unbelievable how little my new investments will amount to (X) vs how much the existing corpus will grow to (8X).

My main takeaway from this newly acquired knowledge is not that I’ll have an easy retirement. The main takeaway is that I should be financially disciplined enough that I am able to manage my day-to-day expenses and other financial goals without touching the current retirement corpus. The corpus will  have a chance to multiply manifold only if I leave it alone and let it grow.

With this revelation, I am able to appreciate the truth behind the saying ‘a bird in the hand is worth two in the bush’. The corpus I already have is precious, and I must do what it takes to protect it. Staying disciplined for the next 21 years is far more important than asset selection or timing the market or chasing current trends. Even if I invest all the new money in an amazing product that gives higher return, it’s going to be incredibly hard to beat my existing corpus.

I always knew that investment duration was a critical factor. But seeing the math for my own corpus makes it all the more real. Discipline is hard when it’s a vague belief. Discipline becomes easier when you know it’ll enrich your life.

Infographic of debt mutual fund durations

Whenever I want to see durations of debt mutual funds, I have to do a Google search, pick a result, and read through some text before I can understand how the debt fund durations stack up. I thought I’d make an infographic so it’s easy to see where each category falls on the spectrum. (I used Groww as the information source.)

The image is not to scale, though many of the boxes should be of a proportional height. Click on the image to magnify it.

When choosing a debt mutual fund, consider both credit risk and interest rate risk. A few previous posts on debt mutual funds:

• Should I invest in short term debt funds or long term debt funds?
• Visualising how interest rate movements affect debt fund yields
• Open-ended target maturity debt funds are an excellent choice
• But why is volatility in debt investment bad?

Some basic ideas of investing

• Investing is just buying, holding, and selling assets.
• Cash is a depreciating asset. Cash depreciates in value over time due to inflation. Other assets such as cars and buildings depreciate due to material depreciation.
• Appreciating assets are a good investment. Depreciating assets are a bad investment.
• Bank deposits are cash. They depreciate like cash, just as liquid as cash, and deposit interest is taxed like cash.
• Price of your assets may change every day… or many times within a day. You don’t need to keep watching every price movement.
• You don’t look at the current market value of your gold jewels or house every week. Treat your stock and mutual fund assets the same way.
• Different assets have different behaviours. Understand your assets before buying them.
• Will this asset appreciate over time, or will it depreciate?
• How hard/easy will it be to sell this in the future, if/when I decide to sell?
• Will I find buyers when I want to sell this in the future?
• How will this asset make money?
• For example, real estate assets provide rent, stocks pay dividends, etc.
• How might this asset lose money?
• For example, cars lose value to depreciation.
• Diversification reduces risk. But it also reduces your maximum return. Another way to look at this is that diversification shields you from extremes, be it extreme loss or extreme profit.
• It’s natural to want extreme profits while wanting to avoid extreme losses. Choose the right amount of diversification for your portfolio considering its benefits and risks.
