How the corpus is calculated
- Today's monthly expenses are inflated to your retirement age.
- The corpus must fund those expenses, rising with inflation every year, until your planning age, while the remaining money earns the post-retirement return.
- Your existing savings are grown to retirement, and the monthly SIP covers the gap.
Example
At 30, spending โน50,000 a month today with 6% inflation, that becomes about โน2.9 lakh a month at 60. Funding that to 85 with a 7% post-retirement return needs a corpus of several crores. Try your own numbers above; small changes in inflation make a big difference.
Ways to close the gap
- Start early. Every 5 years of delay sharply increases the monthly SIP needed.
- Step up your SIP each year with your salary.
- Count EPF, PPF and NPS balances in "savings so far".
