Corpus Calculator
What Is a Corpus Calculator?
A Corpus Calculator is a financial planning tool that helps individuals estimate the amount of wealth they need to accumulate to achieve a specific financial goal.
The calculator helps answer questions such as:
- How much retirement corpus do I need?
- How much money should I accumulate for my child’s education?
- What corpus is required for financial freedom?
- How much wealth is needed to generate passive income?
It helps convert financial goals into measurable investment targets.
What Is a Corpus?
A corpus is the total amount of money accumulated to achieve a financial objective.
Examples:
Retirement Corpus
The amount required to support expenses after retirement.
Education Corpus
The amount required to fund future education costs.
Financial Freedom Corpus
The amount required to become financially independent.
Wealth Creation Corpus
The target amount required to achieve a desired level of wealth.
Why Is Corpus Planning Important?
Many investors invest without a clear target.
A corpus-based approach provides:
- Clear financial goals
- Measurable milestones
- Better investment discipline
- Improved financial planning
Knowing the required corpus helps determine how much needs to be invested today.
Corpus Calculation Concept
A corpus depends on:
- Future expenses
- Inflation
- Investment returns
- Goal duration
- Withdrawal requirements
For example:
If annual expenses are:
₹12 Lakhs
and the desired withdrawal rate is:
4%
Required Corpus:
₹3 Crore
This illustrates how financial goals can be converted into investment targets.
Example Corpus Calculation
Suppose:
Current Monthly Expense:
₹50,000
Inflation:
6%
Years to Goal:
25
Expected Return:
12%
Goal:
Retirement
Result:
Projected Monthly Expense:
₹2.15 Lakhs+
Estimated Retirement Corpus:
₹5–7 Crore
Required Monthly SIP:
Calculated automatically
