SWP Calculator

Planning SWP withdrawals by hand requires compounding calculations repeated dozens or hundreds of times, once for every withdrawal period. A 20-year monthly SWP has 240 compounding events, each dependent on the previous balance. Even a small arithmetic error snowballs into a completely misleading picture of how long your money will last.

A digital SWP Calculator eliminates that guesswork in seconds. You can stress-test your plan instantly: what if markets deliver 6% instead of 8%? What if you need an extra ₹5,000 per month in Year 5? What if you add a 5% annual step-up to match inflation? Each of these what-if scenarios updates your remaining corpus projection and depletion timeline in real time, giving you the confidence to commit to a withdrawal plan.

The step-up feature deserves particular attention. India's retail inflation has averaged 5–6% per annum over the past decade. A fixed ₹20,000 monthly withdrawal today will feel like ₹12,000 in today's money ten years from now. Using the Inflation Calculator alongside SWP helps you calibrate the right step-up rate to protect your purchasing power.

The calculator is equally useful pre-retirement, it tells you exactly how large a corpus you need today to generate a specific monthly income for a target number of years, which you can then use as a goal for your SIP investments.

Retirees drawing monthly income, the primary audience. If you have accumulated a corpus in mutual funds, EPF, gratuity, or from the sale of an asset, SWP is one of the most tax-efficient ways to convert that wealth into regular income. The SWP Calculator tells you the exact withdrawal amount you can sustain for 20 or 25 years without running out of money.

Pre-retirees in the last 5–10 years of work, this is the right time to model your retirement income strategy, not after you retire. Use the calculator to identify your corpus target: if you want ₹60,000 per month for 25 years at 8% returns, you can work backwards to find the corpus you need, and then use a SIP Calculator to plan how to get there.

Investors funding a fixed-term goal, a parent funding four years of a child's overseas education, or an entrepreneur who has sold a business and needs to draw a salary from the proceeds. SWP is not just for retirement; any situation where you need periodic income from a lump sum corpus fits this model.

Retirees comparing SWP to FD, if you currently earn FD interest as your primary income, the SWP Calculator helps you compare whether a debt mutual fund SWP gives you better post-tax, inflation-adjusted returns than your FD interest payout.

NPS annuity planners, after using the NPS Calculator to estimate your NPS corpus at retirement, you can model the lump sum portion (up to 60% of corpus is tax-free) through SWP to complement your NPS annuity income.

Remaining Corpus is the primary output, the money left in your investment after all withdrawals across your chosen period. A positive remaining corpus means your withdrawals were sustainable; the corpus outlasted your plan. A zero or near-zero remaining corpus means you have drawn it down almost completely, which may be intentional (corpus fully consumed by design) or a warning sign (you need to reduce withdrawals). If the corpus depletes before your period ends, the calculator warns you of the exact year this happens.

Total Withdrawn is the cumulative rupee amount you will have received in income across all your withdrawals. This number, added to your remaining corpus, exceeds your initial investment if your returns were positive, the difference is your Returns Earned.

Returns Earned shows how much the market contributed to your withdrawal plan. In a well-structured SWP, a meaningful portion of your total withdrawals comes from returns rather than from drawing down your principal. This is the compounding dividend of staying invested, your corpus keeps working even as you withdraw from it.

The year-by-year schedule beneath the results is where the real insight lives. It shows the opening balance, withdrawals, returns earned, and closing balance for every year of your plan. Look for the crossover point: the year where your annual withdrawals first exceed your annual returns. That is when your corpus starts shrinking. Understanding where this crossover falls, and how far it is from your expected life span, is central to sound retirement planning.

Use the reverse mode to flip the calculation: enter a target remaining corpus (₹0 if you want to fully deplete the fund over the period) and the calculator tells you the maximum sustainable withdrawal per period.

1. Enter your Initial Corpus, this is the lump sum amount you are starting with, whether from a mutual fund accumulation, FD maturity, property sale, or any other source. Most Indian retirees work with amounts between ₹20 lakh and ₹2 crore.

2. Set your Withdrawal Amount, the fixed amount you want to withdraw per period. Start with your estimated monthly household expenses and adjust upward slightly to account for medical costs and travel that tend to rise in retirement.

3. Choose Withdrawal Frequency, select Monthly, Quarterly, Half-Yearly, or Yearly based on when you actually need cash. Most investors choose Monthly for predictable cash flow. If you have a pension or rental income covering basic expenses, Quarterly or Half-Yearly may suit you.

4. Set Annual Step-Up, enter the percentage by which you want your withdrawal to increase each year. A 5–6% step-up is a reasonable proxy for Indian inflation. Leave it at 0% if you want to model fixed withdrawals throughout.

5. Enter Expected Annual Return, this is your assumed annual return on the invested corpus. Use 7–8% for debt-oriented funds, 10–11% for balanced or equity-oriented funds. Be conservative, a lower assumption leaves a margin of safety.

6. Set Withdrawal Period, the number of years you plan to draw income. Plan for at least 25–30 years if you are retiring at 60; medical advances mean a 30-year retirement horizon is increasingly common in India.

7. Read the results, check the Remaining Corpus first. If it is zero or negative (depletion warning), reduce your withdrawal amount or increase your return assumption. Then study the year-by-year schedule to see exactly when and how your corpus evolves. Use the Corpus Depletion Chart to visualise the trajectory.
