Retirement planning: Want to draw ₹50,000 monthly income? Here's how much you need to invest — Maths explained

Smart financial planning for your future during retirement would include not only relying on savings to get by but also using your investments to generate monthly income as per your lifestyle and requirements. Thus, retirement planning demands a careful analysis of various factors, foreseeable or not.

An option that investors can choose to continue earning from their investment even after retirement, and keep the corpus invested, is the systematic withdrawal plan (SWP). This feature allows mutual fund investors to withdraw fixed amounts at regular intervals — monthly or quarterly basis, while keeping the corpus invested.

It is a popular method of monthly or quarterly “encashment” for retired individuals or for supplemental cash flow, as per a Clear Tax report.

How to determine your retirement corpus?

The first step is to identify your goals and aspirational lifestyle post-retirement. This includes your family situation, health status, possible devaluation of net worth due to inflation and other factors.
The next step is to assess your current financial status and earning potential against monthly spends in the present and likely additions in the future. This exercise will help determine how much corpus you will require to accumulate by the time to retire to maintain the lifestyle you want.
It is best to start as early as possible so that you can take advantage of the power of compounding — no matter your choice of investment. Be it safer avenues such as government schemes or the equity markets, nothing adds up better than a longer tenure for returns.

Choose diverse investment paths as per your requirement, goals and age. For those who start young, a higher allocation towards equities can slowly be tapered toward more conservative options as you age. India provides various asset classes to invest such as bank deposits, bonds (fixed income), equities, cash and cash equivalents, equities, real estate and more.
You can also choose investment options based on your salary and tax exemptions requirement, as government schemes such as the PPF, EPF, NPS and NSC allow you to build retirement corpus, while providing some tax benefit at end of tenure.
Further, it is best to also plan for emergencies with a separate fund and / or insurance cover to avoid depleting your retirement savings due to unforeseen circumstances.
A safe calculation that CAs suggest to roughly estimate your retirement corpus is “300 x current monthly expenses”, to be adjusted periodically.
