How It Works
A Systematic Withdrawal Plan (SWP) is the mirror image of a SIP. Instead of contributing a fixed amount every month to build a corpus, you start with a corpus and withdraw a fixed amount every month. The leftover balance keeps earning the assumed rate of return, so the corpus can either last a finite number of years (if you withdraw faster than it earns), or grow indefinitely (if you withdraw less than the return on it).
SWP month-by-month math
The calculator runs a month-by-month simulation. Each month:
- The opening balance earns one month of return:
return = balance × (annualRate / 12 / 100) - The monthly withdrawal is deducted from the post-return balance
- If the post-return balance is less than the target withdrawal, the corpus exhausts that month and the schedule stops
When does the corpus survive forever?
The corpus is mathematically perpetual when your annual withdrawal is less than the annual return on the initial corpus:
monthlyWithdrawal × 12 < initialCorpus × annualRate / 100
For example, ₹25,000/month from a ₹50 lakh corpus is ₹3 lakh/year — well under the ₹4 lakh/year that ₹50 lakh earns at 8%. The balance compounds upward over time.
Why SWP is popular for retirement income
SWP is the standard mutual-fund-based retirement income mechanism. Compared to fixed-deposit monthly interest or SCSS payouts, SWP offers two advantages: it is generally more tax-efficient (only the gain portion of each withdrawal is taxed, not the principal), and the residual corpus continues to participate in market returns. The trade-off is volatility — debt-fund SWPs are smoother, hybrid and equity SWPs can produce a few rough years that need cushioning.
Frequently Asked Questions
A Systematic Withdrawal Plan (SWP) is a mutual fund facility that lets you withdraw a fixed amount every month from your investment, while the remaining balance continues to earn returns. You start with a corpus, set a monthly withdrawal target and a date, and on that date each month the fund house redeems the equivalent number of units and credits the rupee amount to your bank account. The leftover units stay invested and continue to participate in market returns — so unlike a fixed deposit interest payout, your principal can grow even while you withdraw, provided the returns exceed your withdrawal rate.
