About the SWP Calculator
The SWP Calculator on S₹P Calculator Online is a free financial tool that helps you plan systematic withdrawals from your mutual fund corpus. While a SIP (Systematic Investment Plan) is used to accumulate wealth by investing regularly, a SWP (Systematic Withdrawal Plan) does the opposite — it allows you to withdraw a fixed amount every month from your accumulated corpus while the remaining balance continues to grow.
SWPs are particularly popular among retirees in India who want a regular monthly income from their retirement corpus. Instead of withdrawing the entire amount and keeping it in a savings account (which earns only 3-4%), a SWP lets you withdraw only what you need each month while the rest of the corpus continues to earn market returns (typically 8-12% in balanced or debt funds). This can make your retirement corpus last decades longer.
Our SWP calculator simulates month-by-month: (1) the corpus grows by the expected monthly return rate, (2) your fixed withdrawal amount is deducted, (3) the remaining balance compounds to the next month. This continues for the entire tenure. If your withdrawal rate exceeds the return rate, the corpus depletes — eventually reaching zero. The calculator shows you the final balance and warns you if your corpus will be exhausted before the period ends.
How SWP Works — A Real Example
Suppose you have accumulated ₹1 crore in a mutual fund and want ₹50,000 monthly income for 20 years. With an expected return of 8%, here's what happens:
- Year 1: Corpus grows to ₹1.08 crore, you withdraw ₹6 lakh → Balance ₹1.02 crore
- Year 5: Corpus is around ₹95 lakh (withdrawals outpacing returns slightly)
- Year 10: Corpus is around ₹82 lakh
- Year 15: Corpus is around ₹55 lakh
- Year 20: Corpus is around ₹5 lakh (nearly exhausted)
The SWP calculator shows you this trajectory visually with a balance-over-time chart, helping you choose the right withdrawal amount that balances monthly income with corpus longevity.
SWP vs Fixed Deposit — Which is Better for Monthly Income?
Many Indian retirees use fixed deposits (FDs) for monthly income. FDs offer guaranteed returns (currently 6-7% for senior citizens) but the interest is fully taxable at your income slab rate. For someone in the 30% tax bracket, a 7% FD effectively yields only 4.9% post-tax.
SWPs from mutual funds, especially debt funds or balanced advantage funds, can offer better post-tax returns. Withdrawals from equity mutual funds held over 1 year qualify for long-term capital gains tax (12.5% above ₹1.25 lakh annual exemption), which is much lower than slab rates. Debt fund withdrawals are taxed at your slab rate (post-April 2023 rules), but only the gain portion is taxed — the principal withdrawal is tax-free. Use our SWP calculator to compare scenarios.
The 4% Rule for Sustainable Withdrawals
A widely cited rule in retirement planning is the 4% rule: withdraw 4% of your initial corpus annually, adjusted for inflation, and your corpus should last 30+ years. On a ₹1 crore corpus, that's ₹4 lakh per year or about ₹33,333 per month. At an 8% expected return, our SWP calculator shows that a ₹1 crore corpus with ₹33,333 monthly withdrawal will last well over 30 years while preserving most of the principal.
However, the 4% rule assumes a portfolio with significant equity exposure. For conservative debt-heavy portfolios returning 6-7%, a safer withdrawal rate is 3-3.5%. Use our SWP calculator to find the withdrawal rate that works for your specific corpus, return expectations, and time horizon.
