Withdrawal exceeds sustainable rate
Your effective monthly withdrawal (₹10,000/mo) exceeds the maximum sustainable withdrawal (₹7,974/mo). Your corpus will deplete over time.

What is a SWP Calculator?
Understanding Systematic Withdrawal Plans in mutual funds
A Systematic Withdrawal Plan (SWP) calculator helps you estimate how long your mutual fund corpus will last when you withdraw a fixed amount at regular intervals. It is the reverse of a SIP — instead of investing periodically, you withdraw periodically.
SWP is widely used by retirees and investors seeking regular income from their mutual fund investments while the remaining corpus continues to earn returns.
- Regular income: Get a fixed withdrawal monthly, quarterly, or annually
- Corpus grows: Remaining balance continues earning market returns
- Tax efficient: Only the capital gains portion is taxed, not the entire withdrawal
- Flexible: Modify withdrawal amount or stop anytime
- Better than FD: Potentially higher returns than fixed deposit interest
How is SWP Calculated?
The compound interest formula with periodic withdrawals
SWP calculations work by computing the balance after each period, where returns are earned and then a withdrawal is made:
SWP Formula (each period):
Balance = Previous Balance × (1 + r) − WBalance = Remaining corpus after withdrawal
r = Periodic return rate (monthly: (1 + annual_rate)^(1/12) − 1)
W = Withdrawal amount per period
Final Corpus (closed-form):
FV = PV × (1 + r)^n − W × [((1 + r)^n − 1) / r]FV = Future Value (remaining corpus)
PV = Present Value (initial investment)
n = Total number of withdrawal periods
Maximum Sustainable Withdrawal:
The maximum amount you can withdraw monthly without depleting your corpus is: Corpus × Monthly Return Rate. This is the perpetuity withdrawal — your corpus stays intact indefinitely.
Real World Example
A worked calculation showing 10-year SWP withdrawal
Example Calculation:
Suppose you invest ₹10,00,000 (10 Lakhs) in a mutual fund earning 10% annual returns and withdraw ₹10,000 monthly for 10 years:
- Initial Corpus: ₹10,00,000
- Monthly Withdrawal: ₹10,000
- Expected Return: 10% p.a.
- Tenure: 10 years (120 months)
Using the SWP calculator:
- Total Withdrawn: approx ₹12,00,000
- Remaining Corpus: approx ₹5,95,000
- Total Returns Earned: approx ₹7,95,000
Even after withdrawing ₹12 Lakhs, your ₹10 Lakh corpus still has nearly ₹6 Lakhs remaining — thanks to compounding returns!
SWP vs SIP — Key Differences
Understanding the opposite sides of mutual fund investing
| Feature | SWP | SIP |
|---|---|---|
| Purpose | Regular income / withdrawal | Wealth creation / investment |
| Cash Flow | Money flows out of fund | Money flows into fund |
| Best For | Retirees, regular income seekers | Salaried individuals, wealth builders |
| Corpus Direction | Decreasing (or stable if returns > withdrawals) | Increasing over time |
| Tax Efficiency | Only capital gains portion taxed | Taxed at redemption |
Tax Implications of SWP
STCG, LTCG rates for SWP withdrawals from equity and debt funds
SWP withdrawals from mutual funds are more tax-efficient than FD interest because only the capital gains portion is taxable — not the entire withdrawal amount.
Equity Funds (Held > 1 Year):
- LTCG: 12.5% on gains above ₹1.25 Lakh per year
- STCG (held < 1 year): 20%
Debt Funds (Purchased on or after 1 April 2023):
- Gains taxed at your income tax slab rate
- No indexation benefit available
SWP Tax Advantage:
In an SWP, each withdrawal is treated as a partial redemption. This calculator estimates taxable gains using a proportional cost-basis method, where part of each withdrawal is treated as principal and the rest as gain. Since a significant portion of each withdrawal is your own capital (not gains), the effective tax is often lower than FD interest which is fully taxable.
How to Choose the Right SWP Amount
Practical tips for sustainable withdrawal planning
1. Follow the 4% Rule
A widely cited guideline suggests withdrawing no more than 4% of your corpus annually (~0.33% monthly). Originally based on US market data, this rule is a starting point — actual sustainability depends on your return rate and inflation.
2. Keep Withdrawal Below Returns
If your fund earns 10% p.a. and you withdraw less than 10% annually, your corpus will actually grow over time. Our calculator shows the maximum sustainable withdrawal for your corpus.
3. Use Balanced or Hybrid Funds
For SWP, balanced advantage or hybrid funds offer a mix of equity growth and debt stability. This reduces the impact of market volatility on your regular withdrawals.
4. Account for Inflation
Use the Annual Withdrawal Increase (step-up) feature to increase your withdrawal by 5-7% yearly. This helps maintain your purchasing power as costs rise over time.
5. Monitor Corpus Health
Review your SWP annually. If your corpus is depleting faster than expected (due to poor market performance), consider reducing your withdrawal amount temporarily.
