SWP Calculator
Plan a Systematic Withdrawal Plan in India. The SWP calculator shows how long your corpus lasts for any monthly withdrawal and expected return.
A Systematic Withdrawal Plan, or SWP, is the post retirement counterpart to a SIP. Instead of investing a fixed amount each month, you withdraw a fixed amount each month from a mutual fund corpus, and the remaining balance continues to earn returns. The SWP calculator on this page tells you how long any corpus will last under a chosen monthly withdrawal and expected return, and whether the balance will last your full horizon or run out earlier.
Inputs
Why use the SWP Calculator
Most retirees in India face the same uncomfortable question. They have built a corpus, often in equity and hybrid mutual funds, and now they need monthly income. Annuities are tax inefficient. Bank FDs barely beat inflation. An SWP is the cleanest way to convert a corpus into a monthly cash flow while keeping the principal invested. The risk is straightforward, you might withdraw faster than the corpus can replenish itself, in which case it runs out. The calculator stress tests that risk before you start the SWP.
Benefits at a glance
Stress test the 4 percent rule
The classic 4 percent rule says a corpus can sustain a 4 percent annual withdrawal for roughly 30 years if invested in a balanced equity portfolio. Run your numbers through the calculator and see whether the rule works for your specific corpus, return assumption and life expectancy.
See exactly when the corpus exhausts
If the withdrawal is too aggressive, the calculator shows the year and month when the balance hits zero. That is a real warning sign before you commit to a monthly withdrawal mandate.
Compare different return scenarios
What if equity returns only 8 percent in your retirement years instead of 11. What if you keep 30 percent in debt earning 7 percent. The calculator answers each variant in seconds.
Plan for a target ending balance
If you want to leave a corpus to family or charity, set the withdrawal lower so the ending balance shows the legacy amount. The calculator lets you tune the withdrawal until both income and legacy are on track.
How to use the SWP Calculator
- 1
Enter your starting corpus
The total amount you have available for the SWP. For most retirees this is the sum of equity mutual funds, hybrid funds and any debt funds earmarked for income.
- 2
Set the monthly withdrawal
Start with the income you actually need each month after expenses, taxes and other inflows. ₹50,000 is a typical starting figure for a middle income retiree in India.
- 3
Pick the expected return
Eight to nine percent is a reasonable assumption for a balanced post retirement portfolio in India. Use ten to eleven percent if you stay equity heavy, six to seven percent if you shift mostly to debt.
- 4
Choose the duration
Set the duration to your expected retirement length. Twenty five to thirty years is a safe planning horizon if you retire in your sixties.
- 5
Read the ending balance
If the ending balance is positive, your SWP is sustainable. If the calculator says the corpus exhausts, lower the monthly withdrawal or extend your working years to grow the corpus first.
Frequently asked questions
What is an SWP and how does it work?
An SWP, or Systematic Withdrawal Plan, is a feature offered by every Indian mutual fund AMC that automatically redeems units worth a fixed rupee amount on a chosen date each month. The redemption proceeds are credited to your bank account. The remaining units stay invested and continue to earn returns. It is the structural opposite of a SIP.
Is an SWP better than an annuity?
For most Indian retirees, yes. Annuities are tax inefficient because the entire monthly payout is taxed as income, and the underlying capital is locked away. An SWP is more tax efficient because each withdrawal is treated as a redemption of mutual fund units, where only the gain portion is taxed and at capital gains rates. SWPs also keep the principal liquid, so you can adjust the withdrawal or withdraw a lump sum if the need arises.
What is the 4 percent rule and does it work in India?
The 4 percent rule is a US derived guideline that says you can withdraw 4 percent of your corpus in year one and adjust upward for inflation each year, and the corpus will last 30 years in a balanced equity portfolio. For India, with higher equity returns but also higher inflation, many advisors prefer 30 to 35 times annual expenses (a withdrawal rate of roughly 3 percent) for safety. The SWP calculator lets you test what works for your numbers.
How is SWP taxed in India?
Each monthly withdrawal is treated as a partial redemption. For equity oriented funds, the gain portion is long term capital gains if the units were held more than 12 months, taxed at 12.5 percent above ₹1,25,000 of total LTCG in a year as of FY 2025 to 2026. The principal portion is not taxed because it is your own capital being returned. This makes SWPs significantly more tax efficient than fully taxable income from FDs or annuities.
Can the corpus run out during my SWP?
Yes, if the withdrawal exceeds what the corpus can sustainably generate. The calculator shows the exhaustion month explicitly. If you see exhaustion before your planning horizon, you have three options. Lower the withdrawal, increase the corpus by working a few more years, or accept higher equity exposure to lift the expected return.
Should I use SWP from equity or debt funds?
A common pattern is to keep three to five years of expenses in debt and the rest in equity, with the SWP taken from the debt portion. This protects against having to sell equity in a market downturn. You replenish the debt bucket by trimming equity gains in good years. The SWP calculator does not model the bucket strategy directly but you can run it on the equity bucket alone for the years it is expected to fund withdrawals.
Can I change my SWP amount later?
Yes. Stopping or modifying an SWP is a single instruction with the AMC or the platform. Most retirees revise their SWP annually to account for inflation. A few revise it whenever a major expense changes (a child's education ends, a parent's medical needs grow).
Final word
An SWP is one of the cleanest ways for an Indian retiree to convert a hard earned corpus into reliable monthly income. The risk is doing it without looking at the maths. Run the calculator with conservative assumptions before you set up the mandate, and revisit it once a year. If the numbers say the corpus runs out at age 78 and you plan to live to 90, that is a planning gap to close before retirement, not a problem to discover at age 75.
