How Much Money Will You Need?
The estimated cost of living for you and your spouse is usually about 20-30% of your monthly income. The remaining money is either spent as a lifestyle cost or saved for future needs.
So, if you are earning ₹1 lakh now, you are spending about ₹20-30,000 on yourself and your spouse. This is the amount that will translate into personal expenses post-retirement as well.
This amount adjusted for inflation (say, within the range of 3-4% p.a.) could go up to ₹90,000 in 30 years. So, if you are 30 years old now, this is the amount you will need to start your retirement at 60. However, if you wish to retire at 50, you may withdraw a relatively lower amount of approximately ₹80,000.
However, you will then have a longer retirement period to take care of, plus you may still need to take care of a few financial goals. Thus, if you can secure an income slightly higher than ₹90,000, say ₹1 lakh per month after your retirement, you may have an easier life ahead.
Also, this income has to account for future inflation. So, every year, you should be able to withdraw a progressively higher amount. To sustain such a post‑retirement income starting at age 50, a sizeable corpus in the range of about ₹2.8 crore or more may be required, depending on the assumed rate of return and expected lifespan.
