How this is calculated
Corpus = W × (1 − (1 + j)^−n) ÷ j where W = (Expenses − Other income) × (1 + inflation)^years to retirement, j = ((1 + r) ÷ (1 + i))^(1/12) − 1
- W
- First monthly withdrawal at retirement (future money)
- j
- Real (inflation-adjusted) monthly return in retirement
- n
- Months from retirement to the planning age
Your current monthly expenses are first projected to retirement-date prices. The corpus is then the amount that, earning your post-retirement return, can pay those expenses every month — rising with inflation — until your planning age, reaching zero at the end. Planning to an age beyond average life expectancy keeps the plan safe if you live longer.
Assumptions & sources
- In retirement, monthly expenses (net of other income) are withdrawn and rise with inflation; the corpus needed is their present value at the real return, (1 + return) ÷ (1 + inflation) − 1, compounded monthly.
- Returns and inflation are constant averages — real markets vary year to year, and a bad sequence early in retirement matters most.
- Taxes on withdrawals and investment gains are not deducted.
- The corpus is fully used up by the planning age; nothing is left as an inheritance.

Common questions
How is the corpus worked out?
It is the present value, at retirement, of all your future monthly expenses, each rising with inflation, discounted at your expected return in retirement — the amount that runs down to exactly zero at your planning age.
Why is the number so large?
Inflation compounds over the years to retirement and again during retirement. ₹50,000 a month today is about ₹2.1 lakh a month in 25 years at 6 % inflation.
Should I include EPF, PPF and NPS?
They are part of your savings toward this corpus, not reductions of it. Use the Retirement Readiness Planner to compare what you'll have with what you need. An NPS annuity or other pension does reduce the corpus — enter it as other income.
