Retirement • Inflation and corpus planning
Retirement Calculator for India
Estimate how today's expenses may change by retirement, compare an illustrative corpus target with projected savings, and identify a possible planning gap.
Enter planning assumptions

How to use it
- Enter current and retirement ages.
- Use essential monthly expenses in today's rupees.
- Add reasonable inflation and return assumptions.
- Enter existing retirement savings and monthly contributions.
- Review the target, projection and possible gap under several scenarios.
Formula and methodology
Expense at retirement = current expense × (1 + inflation)years
Illustrative target = annual retirement expense ÷ 0.04
Existing savings grow monthly, while contributions use a beginning-of-month annuity. The 4% rule is only a general heuristic. Currency values are rounded to the nearest rupee.
Worked Indian example
For age 35, retirement at 60, today's expenses of ₹50,000, 6% inflation, 10% return, ₹5,00,000 current corpus and ₹15,000 monthly contribution:
| Monthly expense at retirement | ₹2,14,594 |
|---|---|
| Illustrative target corpus | ₹6,43,78,061 |
| Projected corpus | ₹2,60,96,828 |
| Estimated shortfall | ₹3,82,81,233 |
The example shows sensitivity to inflation and long horizons. It does not include pension, rental income, tax, healthcare shocks or post-retirement returns.
How to interpret the estimate
A shortfall is a prompt to revisit contributions, retirement age, future spending and other income—not an instruction to chase higher returns. A surplus is not a guarantee because actual inflation, longevity and market results can differ.
Common mistakes
- Ignoring healthcare and irregular expenses.
- Assuming one high return for decades.
- Counting a home without deciding whether it will fund retirement.
- Forgetting pension, EPF, PPF or other income.
Practical planning tips
- Test higher inflation and lower returns.
- Increase contributions after salary growth where affordable.
- Keep insurance and emergency planning separate.
- Review nominations and account records.
- Recalculate annually using actual balances.
