How to Use the SWP Calculator
A Systematic Withdrawal Plan lets you withdraw a fixed amount regularly from investments while the balance keeps growing.
- Enter your total investment.
- Enter the monthly withdrawal amount.
- Enter the expected return and duration.
- See how long your corpus lasts and the final balance.
SWP Logic
Monthly Balance
Balance = (Balance − Withdrawal) × (1 + r/12)
Each month a withdrawal is taken, then the remainder grows.
Example:
Input: ₹10L, ₹10k/mo, 9%
Calculation: iterated monthly
Result: lasts ~13+ years
Real-World Use Cases
Retirement Income

Tips
