Formula used
Retirement corpus = (monthly expenses at retirement × years in retirement) / (post-retirement return - inflation rate). Uses perpetuity formula.
Example calculation
A 30-year-old earning ₹50,000/month wanting to retire at 60 needs approximately ₹1.5-2 crore corpus (today's value) at 6% inflation and 8% post-retirement return.
How to use this calculator
- Enter current age, retirement age, and expected life age.
- Enter current monthly expenses and reduction post-retirement.
- Enter existing corpus and current monthly SIP.
- Review corpus needed, projected corpus, and shortfall.
Important assumptions
- Expenses reduce post-retirement (no EMI, fewer discretionary expenses).
- Inflation is constant throughout the planning period.
- Returns are estimated — actual returns vary.
- No Social Security or pension income included.
Why retirement planning matters
India's average life expectancy is 70+ years. With retirement at 60, you may need funds for 25+ years.
The power of starting early
Investing ₹5,000/month from age 25 at 12% gives ₹1.1 crore by 60. Starting at 35 requires ₹12,000/month.
Common retirement mistakes
Underestimating expenses, ignoring inflation, not diversifying, relying only on PF/NPS, and starting too late.
