A Systematic Withdrawal Plan (SWP) lets you withdraw a fixed amount from your mutual fund investment at regular intervals — making it an excellent retirement income tool. The key is choosing a withdrawal rate that sustains your corpus. Use the calculator above to find the right balance between monthly income and corpus longevity.
How Long Your Corpus Lasts at Different Withdrawal Rates
| Corpus | ₹10,000/month | ₹20,000/month | ₹30,000/month | ₹50,000/month |
|---|---|---|---|---|
| ₹20L | 30+ years | 12 years | 7.5 years | 4.2 years |
| ₹50L | 30+ years | 30+ years | 25 years | 12 years |
| ₹1Cr | 30+ years | 30+ years | 30+ years | 30+ years |
*Assuming 10% annual returns on the remaining corpus. 30+ years = corpus sustains indefinitely.
SWP vs Other Monthly Income Options
| Feature | SWP | FD Monthly Payout | Annuity |
|---|---|---|---|
| Returns | 8-12% (market-linked) | 6-7% (fixed) | 5-7% (fixed) |
| Tax Efficiency | High (LTCG only) | Low (fully taxable) | Low (fully taxable) |
| Corpus Preservation | Partial (withdrawals + growth) | Full (only interest paid) | None (corpus gone) |
| Flexibility | Change amount anytime | Fixed at booking | Fixed at purchase |
How SWP Works
In plain words
SWP (Systematic Withdrawal Plan) lets you withdraw a fixed amount from your investment corpus at regular intervals. The remaining corpus continues to earn returns. If the withdrawal rate exceeds the return rate, the corpus will eventually deplete.
Balance = Previous Balance × (1 + r) - W
Where:
r = Monthly Return Rate (Annual Rate ÷ 12 ÷ 100)
W = Monthly Withdrawal Amount
Balance starts at the initial corpus and decreases each month after withdrawal.A quick example
Let us calculate SWP sustainability for a typical retirement scenario:
Step by step
- 1.Monthly return r = 10% ÷ 12 ÷ 100 = 0.00833
- 2.Each month: Balance = Balance × 1.00833 - 10,000
- 3.After 15 years (180 months), calculate remaining balance
- 4.If balance > 0, corpus sustains the full period
- 5.Max sustainable withdrawal = Corpus × r = 20,00,000 × 0.00833 = ₹16,667/month
So the answer is: With ₹10,000/month withdrawal at 10% return, the corpus sustains beyond 15 years.
