SWP Calculator — Will Your Corpus Last?
Find out if your corpus will last — and how much you can safely withdraw each month.
What is SWP (Systematic Withdrawal Plan)?
A Systematic Withdrawal Plan (SWP) is a facility offered by mutual funds that allows you to withdraw a fixed amount from your investment at regular intervals — monthly, quarterly, or annually. It is essentially the reverse of a SIP. Instead of putting money in regularly, you take money out regularly, while the remaining corpus continues to grow.
SWP is particularly popular among retirees who need a regular income stream without depleting their entire corpus at once. Unlike an FD, an SWP can be structured so that withdrawals come primarily from capital gains, minimising tax.
How SWP Works
When you set up an SWP, the mutual fund redeems units equal to the withdrawal amount at the prevailing NAV each period. If the fund grows faster than your withdrawal rate, your corpus actually grows over time. If your withdrawal rate exceeds the fund's returns, the corpus shrinks gradually.
SWP Calculation Example
| Initial Corpus | ₹25,00,000 |
| Monthly Withdrawal | ₹20,000 |
| Expected Annual Return | 12% |
| Period | 10 years |
| Total Withdrawn | ₹24,00,000 |
| Remaining Corpus after 10yr | ₹36,50,193 |
The corpus grows because the 12% annual return exceeds the withdrawal rate of ~9.6%.
SWP vs Fixed Deposit for Retirement
| Feature | SWP (Equity Fund) | FD |
|---|---|---|
| Monthly Income | Flexible withdrawal | Fixed interest payout |
| Corpus Growth | Can grow even while withdrawing | Fixed, no growth |
| Tax on Withdrawals | Only gain portion taxed (LTCG/STCG) | Full interest taxable at slab rate |
| Inflation Protection | Yes (equity grows with inflation) | No (fixed rate) |
| Risk | Market-linked | None (up to ₹5L DICGC insured) |
How to Use SWP for Retirement Income in India
- The bucket strategy: Keep 1–2 years of expenses in a liquid fund, 3–5 years in a short-duration debt fund, and the rest in equity/balanced funds. Set SWP from the liquid bucket and refill periodically.
- Sustainable withdrawal rate: Withdraw no more than 6–7% of corpus annually from balanced funds. Higher than the fund's expected return will eventually deplete the corpus.
- Tax efficiency: Each SWP redemption consists of original cost (untaxed) and gains (LTCG 12.5% with ₹1.25L annual exemption). Far more efficient than FD interest, which is 100% taxable at your slab rate.
- Inflation protection: Equity funds growing at 12%+ allow your corpus to grow even while withdrawing — preserving purchasing power over 20–30 years of retirement.
