How to use this step-up SIP and SWP calculator

1. Pick a tab. Use “Step-Up SIP” to plan wealth creation and “SWP” to plan regular income from a corpus.
2. Enter your numbers. Type a value or drag the slider. For a SIP, enter the monthly amount, yearly step-up, expected return, duration and inflation. For an SWP, enter the starting corpus, monthly withdrawal, yearly increase in withdrawal, return and duration.
3. Read the summary. The dark card shows the headline result. The cards below split it into invested amount, gains, inflation-adjusted value and, for SIPs, how much extra wealth the step-up creates over a flat SIP.
4. Check the table. The year-wise breakdown shows exactly how the balance moves each year. Download it as a CSV to open in Excel or Google Sheets.
5. Share or print. “Copy share link” reopens this page with your inputs filled in, so you can send a plan to a family member or your adviser.

Worked example 1: how the step-up percentage changes the result

Assume a starting SIP of ₹10,000 a month, 12% expected annual return and a 15-year horizon. Only the yearly step-up changes in the table below.

A 10% step-up more than doubles what you put in (₹18 lakh to ₹38.1 lakh), and the maturity value rises by about ₹36 lakh compared with a flat SIP. The extra money is not only the larger instalments. It is also the compounding on those instalments in the later years. Compare the result with how much your salary is likely to grow before choosing a percentage you can actually sustain.

Worked example 2: the effect of time

Same assumptions (₹10,000 start, 12% return), but now with a 10% yearly step-up against a flat SIP over different durations.

The gap widens sharply after year 15. This is why starting early matters even more than starting big. Note that the step-up instalment also grows large in later years: with a 10% step-up, the monthly SIP in year 25 is roughly ten times the starting amount, so make sure it is realistic for your income.

How long to reach ₹1 crore?

With a ₹10,000 starting SIP and a 12% return, a flat SIP crosses ₹1 crore in about 21 years. With a 10% yearly step-up it takes about 16 years. Try different combinations in the calculator to see how a higher starting amount, a bigger step-up or a longer horizon moves your own target date.

How to choose a step-up percentage

• Match it to your income growth. If your salary rises 8 to 10% a year, a 5 to 10% step-up is usually comfortable.
• Start modest. A step-up you can keep is better than an aggressive one you pause in year four.
• Use bonuses and raises. Many investors raise the SIP only when they get an increment. That is a manual step-up, and you can approximate it here by using the yearly percentage.
• Check the final-year SIP. The calculator shows the monthly SIP in the last year. If that number looks unaffordable, lower the step-up or shorten the duration.
• Set it up with your fund house. Most AMCs and platforms offer a “SIP top-up” or “step-up” option at the time of registering the SIP, so the increase happens automatically.

Understanding the SWP tab

A Systematic Withdrawal Plan redeems a fixed amount from your mutual fund every month. Each withdrawal sells some units, and the units that remain stay invested and keep growing. The key question is not “how much can I withdraw” but “how long will the corpus last.” The calculator answers that by showing the closing balance each year and warning you if the money runs out.

Here are three examples with a ₹1 crore corpus, 8% return and a 25-year horizon.

The first row withdraws 4.8% of the corpus in year one, so the 8% return outpaces the withdrawals and the balance keeps growing. In the third row the withdrawal starts at 7.2% and also rises every year, which drains the corpus well before 25 years. Small changes in the starting withdrawal rate or the yearly increase make a large difference over long periods.

Tips for planning withdrawals

• Keep the starting withdrawal rate conservative. Many planners use roughly 3 to 4% of the corpus a year as a starting point for long retirements. It is a rule of thumb, not a guarantee.
• Allow for inflation. Expenses rise over time, so a fixed withdrawal loses buying power. Use the yearly increase field to test this.
• Be careful with the return assumption. A retiree usually holds a mix of equity and debt, so a single 12% return would be too optimistic for an income portfolio. Test 6%, 8% and 10%.
• Mind the order of returns. Poor markets in the first few years of withdrawals hurt far more than the same poor years later. This calculator assumes a steady return, so keep a safety margin.
• Keep an emergency buffer. Many investors keep one to two years of expenses in a debt fund or savings account so they are not forced to sell equity in a falling market.

Taxes on SIP gains and SWP withdrawals

This calculator shows pre-tax figures, so your actual in-hand amount will be lower. As of FY 2026-27, the general rules for equity-oriented mutual funds (65% or more in domestic equity) are:

• Units held for 12 months or less: short-term capital gains taxed at 20%.
• Units held for more than 12 months: long-term capital gains taxed at 12.5% on gains above ₹1.25 lakh in a financial year, with no indexation.
• Debt funds bought on or after 1 April 2023 are taxed at your income-tax slab rate, regardless of how long you hold them.
• Cess and surcharge may apply on top of these rates.

Every SIP instalment is a separate purchase with its own holding period, and an SWP redeems the oldest units first. Only the gain portion of each withdrawal is taxable, not the full amount, because part of every withdrawal is your own capital coming back. Tax rules change with each Budget, so confirm the current rates on the Income Tax Department website or with a qualified tax professional before you act.

Common mistakes to avoid

• Assuming a fixed return. Equity returns are uneven. A 12% average can include years of 30% and years of minus 20%.
• Ignoring inflation. A crore in 20 years buys much less than a crore today. Check the inflation-adjusted card.
• Choosing a step-up you cannot afford. A 20% step-up looks great in a calculator and fails in real life.
• Stopping the SIP in a market fall. Falling markets are when SIPs buy more units. Stopping often locks in the worst outcome.
• Withdrawing too much too early. An SWP rate that feels fine in year one can empty the corpus in year 15.
• Forgetting costs and taxes. Expense ratios, exit loads and capital gains tax all reduce the final amount.

Limitations of this calculator

The calculator assumes a constant annual return, instalments at the start of every month, and a step-up applied once every 12 months. It does not account for taxes, expense ratios, exit loads, stamp duty, missed instalments or market volatility. Real portfolios will differ from these projections, so treat the output as a planning aid, not a promise.
