SWP Calculator

Estimate how long your savings or retirement corpus will support regular monthly withdrawals.


What Is the SWP Calculator?

A Systematic Withdrawal Plan allows you to withdraw a fixed amount from your investment corpus at regular intervals, providing a steady income stream while the remaining corpus continues to earn returns. Our SWP Calculator helps you plan how much you can withdraw sustainably.

SWP is commonly used by retirees who have built a retirement corpus and need regular income to cover living expenses. Instead of withdrawing lump sums ad hoc, an SWP provides structured payouts that can be scheduled monthly, quarterly, or annually.

Retirees, individuals planning for early retirement, and anyone creating a passive income stream from their investments will find this calculator essential for sustainable withdrawal planning.

Real-World Example

Meet Mr. Mehta. Aged 60, he has a retirement corpus of 1,20,00,000 invested in a balanced portfolio expected to return 9% per annum. He needs a monthly withdrawal of 50,000.

Using the SWP Calculator:

Retirement Corpus

1,20,00,000

Expected Return

9% p.a.

Monthly Withdrawal

50,000

Withdrawal Period

30 years

Corpus at End

65,00,000

If Withdrawal Increased

75,000 depletes in 22 years

Mr. Mehta chooses to keep his withdrawal at 50,000 and reinvest the remaining corpus for his heirs.

The Mathematics Behind SWP Sustainability

SWP calculation models the corpus balance over time, accounting for withdrawals and continued investment returns:

Balance = P × (1 + r)n - W × [((1 + r)n - 1) / r]
P= Initial investment corpus
r= Monthly rate of return (Annual ÷ 12 ÷ 100)
n= Total months of withdrawal
W= Monthly withdrawal amount

Frequently Asked Questions

The commonly cited safe withdrawal rate is 4% of the initial corpus per year, adjusted for inflation. A 4% withdrawal rate has a high probability of sustaining a portfolio for 30 years based on historical data.

Market volatility can significantly impact SWP. If the market declines in early years, you sell units at lower prices, accelerating depletion. Having a cash buffer or reducing withdrawals during downturns helps mitigate this risk.

Yes, most SWP facilities allow you to modify the withdrawal amount, frequency, or even pause withdrawals. Review your SWP annually and adjust based on portfolio performance.

The minimum corpus required depends on your withdrawal needs and the fund minimums. Most mutual funds require a minimum corpus of 50,000 to 1,00,000 to start an SWP. You also need sufficient units to cover the withdrawal amount each period.

SWP withdrawals are subject to capital gains tax based on the holding period of the redeemed units. For equity funds, LTCG above 1,00,000 per year is taxed at 10%. For debt funds, gains are added to your income and taxed as per your slab. Each withdrawal is treated as a sale of units.

Most mutual funds require a minimum holding period of 3-6 months before starting an SWP to avoid exit load charges. Starting immediately may trigger exit load on the units redeemed. Check the fund's exit load structure and plan your SWP start date accordingly to avoid unnecessary charges.

In a dividend option, the fund distributes a portion of its earnings regardless of market conditions. In an SWP, you redeem a fixed number of units at the prevailing NAV. SWP offers more control over the withdrawal amount and timing. SWP is generally more tax-efficient than dividends which are added to your income and taxed as per slab.

For a sustainable Rs 50,000 monthly withdrawal (Rs 6 lakh annually), using the 4% rule, you need a corpus of approximately Rs 1.5 crore (Rs 6,00,000 / 0.04). For Indian conditions with higher inflation, a 3.5% withdrawal rate is safer, requiring about Rs 1.71 crore.

Yes, a common strategy is to combine SWP from equity funds with fixed income from SCSS, Post Office MIS, or bank FDs. For example, if you need Rs 80,000 monthly, you could get Rs 20,000 from SCSS, Rs 15,000 from MIS, and the remaining Rs 45,000 through SWP from a balanced fund.

During a market crash, SWP redeems more units to generate the same withdrawal amount because NAV is lower. This accelerates corpus depletion, known as sequencing risk. To mitigate this, maintain a 2-3 year cash buffer in liquid funds and withdraw from it during downturns.

Key Takeaways

1

SWP provides a structured, regular income stream from your investment corpus.

2

A sustainable withdrawal rate is critical to ensure your corpus lasts your lifetime.

3

Sequence-of-returns risk is highest in early withdrawal years and requires careful planning.

4

Regular review and adjustment of withdrawal amounts help maintain sustainability.

5

SWP can be combined with other income sources like pensions for comprehensive retirement planning.

Why This Matters

SWP is the bridge between your accumulated retirement corpus and regular income needs. Getting the withdrawal rate right determines whether your savings last your lifetime.
