SWP Calculator

SWP (Systematic Withdrawal Plan) lets you redeem a fixed amount from your mutual fund every month at NAV-based prices, while dividends are declared by the fund at its discretion and come from your own NAV. After the 2020 tax change, dividends are taxed at your full income slab rate — but SWP redemptions are taxed only on the gain portion (LTCG at 12.5% for equity held 1+ year). SWP also gives you complete control over the amount and timing, unlike dividends which are irregular and may reduce NAV unexpectedly.

Use the formula n = −ln(1 − C×r/W) ÷ ln(1+r), where C is corpus, r is monthly rate, and W is monthly withdrawal. If W ≤ C×r (withdrawal ≤ monthly return), your corpus lasts forever — this is the ideal scenario. Above that threshold, each month erodes the corpus until it reaches zero. This calculator solves the formula instantly — just enter your corpus, withdrawal, and expected return to see exactly how many years your money lasts.

Yes, each SWP instalment is treated as a redemption and taxed on the gain portion only (not the full withdrawal). For equity mutual funds, units held less than 12 months attract STCG at 20%; units held 12+ months attract LTCG at 12.5% on gains above ₹1.25 lakh per year. The principal portion of each redemption is not taxable. Debt fund SWP gains are taxed at your income slab rate regardless of holding period (post-2023 budget rules).

Most mutual fund AMCs set a minimum SWP amount of ₹500 to ₹1,000 per instalment. There is no maximum — you can withdraw any amount up to the fund's current value. However, you must maintain a minimum balance in the fund as specified by the AMC (typically ₹500 to ₹1,000 in remaining units). Check your specific fund's SWP terms before setting it up.

SWP can effectively replace a pension if your corpus is large enough and your withdrawal rate is below the monthly return earned. For example, a ₹1 Crore corpus at 10% annual return generates ₹83,333/month — more than many government pensions. Unlike a pension, SWP is flexible (you can change amounts or stop), but it carries market risk. Most financial planners recommend combining SWP from mutual funds with a fixed annuity from NPS or LIC for a balanced retirement income strategy.

For long-term retirement SWP, Balanced Advantage Funds (BAF) and Aggressive Hybrid Funds are the most recommended — they offer equity-like returns (10–12% long-term) with lower volatility than pure equity. For conservative investors or SWP duration under 5 years, conservative hybrid or short-duration debt funds (7–8% returns) are safer. Avoid pure equity funds for SWP unless your investment horizon is 10+ years and corpus is large enough to absorb short-term volatility.

During negative return periods, your SWP withdrawals come entirely from principal — the corpus depletes faster than the formula predicts. This is called "sequence-of-returns risk" and is the biggest danger for new retirees starting SWP in a bear market. To mitigate this, keep a cash buffer of 12–18 months of withdrawals in a liquid fund and pause or reduce SWP during severe market downturns (more than 20% drawdown) until recovery.

Yes — SWP is fully flexible. You can pause, reduce, increase, or stop it at any time through the AMC's app or website, with no penalty in most cases. The request typically needs to be submitted 7–10 business days before the next SWP debit date. Your remaining units stay invested in the fund and continue to earn returns during the pause. This flexibility makes SWP far more convenient than annuity products or FD laddering strategies.

For most retirees in higher tax brackets, SWP from a balanced/equity mutual fund is more tax-efficient than FD interest. FD interest is fully taxable at your income slab rate (up to 30%), while SWP from equity funds is taxed only on the gain portion at 12.5% LTCG above ₹1.25L — saving up to 18% in taxes. However, FD gives guaranteed, predictable returns while SWP carries market risk. The optimal strategy is usually a combination: FD for the guaranteed base income and SWP from mutual funds for the inflation-beating growth portion.

SWP is one of the best tools for retirement income if used correctly. It provides monthly income like a salary, keeps the remaining corpus invested and growing, is more tax-efficient than dividends or FD interest, and is fully flexible to adjust as needs change. The key is sizing the withdrawal correctly — ideally below the monthly return earned (so corpus never depletes) and having a separate emergency corpus of 12 months' expenses. A ₹50 Lakh to ₹1 Crore corpus in a Balanced Advantage Fund with a 4–5% annual withdrawal rate is widely considered a sustainable retirement SWP setup.
