SWP Calculator

A Systematic Withdrawal Plan (SWP) is an instruction you give to a mutual fund: "Redeem ₹X from my account on the Nth of every month and credit it to my bank." The fund sells the required number of units at the prevailing NAV and transfers the cash.

The remaining units continue to grow with the fund's NAV. If the NAV grows faster than your withdrawal rate, the corpus can last indefinitely. If you withdraw faster than the fund grows, the corpus shrinks — and eventually depletes.

SWP is not income from the fund. The fund has no obligation to pay you anything. You are redeeming your own investment — a key distinction from the IDCW (dividend) option, where the fund manager decides what to pay and when.

Both FD interest and SWP give you monthly cash flow from a lump sum. The difference is in returns, tax, and capital safety.

For a retiree with ₹1 crore at 8% annualised: perpetuity SWP gives ₹66,667/month. FD at 7.5% gives ₹62,500/month interest. After tax at 30% slab, FD yields ₹43,750/month. At the same 30% slab, equity SWP on ₹1 crore gives ₹66,667 — but annual gains of ~₹8L exceed the ₹1.25L LTCG exemption, so ₹81,250 in LTCG tax applies (₹6,771/month equivalent), yielding ~₹59,896/month. Still ahead of FD post-tax, and the corpus remains intact.

The IDCW (Income Distribution cum Capital Withdrawal) option was formerly called the "dividend plan." SEBI renamed it in 2021 to accurately reflect what it is: the fund distributes part of its accumulated gains back to unitholders, reducing the NAV by exactly the dividend amount.

Key differences from SWP:

• Predictability: SWP pays you the exact amount you specify, on the date you specify. IDCW is declared by the fund manager — unpredictable in timing and amount. In a bad year, the dividend may be cut to zero.
• Tax: IDCW is taxed as "Income from Other Sources" at your slab rate (up to 30%). SWP gains on equity MF held over 12 months are LTCG at 12.5% with a ₹1.25L exemption — almost always lower.
• NAV impact: When IDCW is declared, the NAV drops by the dividend amount — you haven't gained anything, just received your own money in a different form. SWP redeems units at current NAV without a forced NAV adjustment.

For retirement income purposes, SWP from a growth-option equity fund is almost always more tax-efficient and predictable than the IDCW option.

Units are redeemed on FIFO (First-In, First-Out) basis. The actual tax depends on the purchase date of each specific unit batch. Consult a CA for precise computation. Verify LTCG rates and exemption limits after each Union Budget.

Each SWP redemption sells exactly enough units to meet the withdrawal amount:

Units redeemed = SWP amount ÷ NAV on redemption date

Example: ₹30,000 SWP instruction on a day when the fund's NAV is ₹250. Units redeemed = 30,000 ÷ 250 = 120 units.

The FIFO rule means the oldest units in your account are treated as redeemed first. If you invested a lump sum 2 years ago and started SWP 1 year ago, all units being redeemed today have a 2-year holding period — qualifying as LTCG.

Practical tip: Start SWP at least 12 months after your initial investment. This ensures every SWP redemption from day one qualifies as LTCG (12.5% with ₹1.25L exemption) rather than STCG (20% flat, no exemption).

The global "4% rule" says: withdraw 4% of your corpus per year — it will last at least 30 years in most historical scenarios. This was derived from US stock and bond market data from 1926 to 1994 by William Bengen.

India context: the Nifty 50 has compounded at 12–14% nominally over 20-year periods, but India's average CPI is 5.5–6%. Real returns (after inflation) are similar to US historical returns. The sequence-of-returns risk is also similar.

Conservative safe withdrawal rate guidance for Indian equity-oriented portfolios:

• 4–5% per year (or 0.33–0.42%/month) for a 25–30 year horizon.
• On ₹1 crore: ₹33,333–₹41,667/month.
• On ₹50 lakh: ₹16,667–₹20,833/month.

Higher withdrawal rates (5–6%/year) are mathematically viable if returns hold, but carry sequencing risk — a severe market fall in years 1–3 of retirement can permanently impair the corpus even if markets recover later.

• Starting SWP within 12 months of investment: All early redemptions are STCG at 20%. Wait at least 12 months to lock in LTCG treatment.
• Fixed withdrawal ignoring inflation: ₹30,000/month today has the purchasing power of only ₹14,700 in 12 years at 6% inflation. Plan for step-up SWP or a higher initial corpus.
• Over-withdrawing in a bear market: Selling more units at low NAV during a downturn permanently reduces your unit count. Consider keeping 12–24 months of expenses in a liquid/debt fund as a buffer, and pause SWP from equity during severe drawdowns.
• Choosing IDCW over SWP from equity: IDCW is taxed at slab rate on the entire dividend; SWP LTCG at 12.5% above ₹1.25L. Most retirees benefit more from SWP.
• Not declaring SWP gains in ITR: Capital gains from SWP must be declared in your ITR every year, even if the total LTCG is below ₹1.25L. Omission can attract notice from ITD.
• Using a debt fund for SWP without planning for tax: Debt MF gains are taxed at slab rate since April 2023 — effectively the same as FD interest. Factor this into post-tax yield calculations before choosing a debt fund for SWP.
