What Is a SIP Calculator?

A SIP calculator is a free online tool that estimates how much your monthly mutual fund investment will grow over a chosen period. It takes three simple inputs: your monthly amount, expected annual return, and investment duration. It then shows your projected corpus, the total amount you invested, and the estimated returns you earned.

The PlanMyReturns SIP calculator goes further than a basic tool. It supports step-up SIP, where your monthly investment rises every year. It handles multiple contribution frequencies. It gives you a full year-by-year breakdown so you can see exactly how your wealth builds.

Features of the PlanMyReturns SIP Calculator

This tool is built to do more than a single calculation. Here is what you can use.

• Monthly investment, duration, and expected return as your three core inputs.
• An advanced panel for annual step-up percentage, so you can model a rising SIP.
• Contribution frequency options: monthly, quarterly, half-yearly, and yearly.
• Quick SIP examples for Starter, Wealth, Retirement, and Car goals, so you can test a scenario in one click.
• A live SIP summary showing invested amount, estimated returns, and total value.
• A wealth growth chart that plots your invested amount against your market value over the years.
• A year-wise breakdown table with invested amount, estimated returns, and market value for each year.
• A Download CSV button to export the full year-wise schedule.
• A Share Image button and a Share Plan link, so you can save or send your personalised plan.

What Is SIP (Systematic Investment Plan)?

A Systematic Investment Plan, commonly called SIP, is a method of investing a fixed amount into a mutual fund at regular intervals, usually every month. Instead of putting a large lump sum into the market at once, SIP breaks your investment into smaller, regular contributions.

This gives you two powerful advantages.

Rupee cost averaging. Because you invest at regular intervals regardless of market conditions, you buy more units when prices are low and fewer when prices are high. Over time, this averages out your cost per unit.

The power of compounding. Every rupee you invest starts earning returns, and those returns earn further returns. The longer you stay invested, the more strongly compounding works in your favour.

SIP has become the default way Indians build wealth. According to industry data tracked by AMFI, the number of active SIP accounts has crossed 9 crore, and monthly SIP contributions have grown sharply year after year. It is used for long-term wealth creation, retirement, children’s education, buying a home, and nearly every major financial goal.

How Does the SIP Calculator Work?

The calculator uses the future value of an annuity formula, applied month by month for precision.

FV = P × { [(1 + r)ⁿ − 1] / r } × (1 + r)

Where:

• FV is the future value, your final corpus
• P is the monthly SIP amount
• r is the monthly interest rate
• n is the total number of months, which is years multiplied by 12

The monthly rate is not simply the annual rate divided by 12. The correct conversion is:

Monthly rate = (1 + Annual rate)^(1/12) − 1

For example, at a 12% annual return, the monthly rate is (1.12)^(1/12) − 1, which equals about 0.9489% per month, not 1%. Using 1% would overstate your results. PlanMyReturns uses the correct formula for a realistic estimate.

A Worked Example

Monthly SIP of ₹10,000, for 15 years, at 12% per year.

• Total invested: ₹18,00,000
• Estimated returns: ₹32,03,000
• Total corpus: ₹50,03,000

Your ₹18 lakh invested grows to nearly ₹50 lakh, simply from the discipline of investing ₹10,000 every month.

How Much SIP Do You Need to Reach ₹1 Crore?

This is the most searched SIP question in India. Here is the answer at a 12% annual return.

The table shows one critical insight. Time matters more than amount. To reach ₹1 crore, you need ₹43,500 a month if you invest for 10 years, but only ₹10,000 a month if you start 20 years early. Starting early cuts your required monthly SIP by more than 75%.

Use the calculator above to find your exact number based on your own timeline and return assumption. You can also try our Crorepati Calculator for goal-first planning.

What Starting One Year Late Costs You

Delay is the most expensive mistake in SIP investing, and it rarely feels like one.

Take a ₹10,000 monthly SIP at 12% for 20 years. Start on time and you build close to ₹1 crore. Delay the start by just one year and you invest for 19 years instead. The final corpus falls by roughly ₹10 lakh, even though you only skipped 12 instalments of ₹10,000.

The lost year is not the ₹1.2 lakh you did not invest. It is the compounding that money would have earned over the next two decades. This is why the best time to start a SIP is now, even with a small amount.

Step-Up SIP vs Regular SIP: Which Builds More Wealth?

A step-up SIP, also called a top-up SIP, automatically increases your monthly investment by a fixed percentage every year. Most investors choose 10% a year, matching a typical salary increment.

A 10% annual step-up on a ₹5,000 SIP doubles your final corpus compared to a flat SIP, without changing your starting amount.

The logic is simple. As your income grows with each raise, investing a slightly higher amount each year costs you little in lifestyle terms, but compounds massively over decades.

Who Should Use Step-Up SIP?

Anyone with a salaried income that grows every year. If you receive a 10% raise, directing even half of that increment into your SIP can transform your retirement corpus. Enable the step-up option in the advanced panel of the calculator above to see the difference on your own numbers.

What Return Rate Should You Use?

This is where most investors get confused. Here is a realistic guide based on historical mutual fund category performance in India.

For goals more than 10 years away, such as retirement or a child’s education, use the moderate estimate. For goals under 5 years, use the conservative estimate. Never plan long-term goals using the optimistic column, because markets can disappoint for years before rewarding patience.

For most salaried investors planning 15 to 20 years in diversified equity mutual funds, 12% is a reasonable and commonly used planning assumption.

Is Monthly SIP Better Than Quarterly or Yearly?

Most investors choose monthly SIP, and for good reason.

Monthly SIP wins because it buys units 12 times a year across market highs and lows. Quarterly SIP misses 8 months of cost averaging. Yearly SIP concentrates your entire investment into one market point, which defeats the purpose. Unless your income arrives quarterly, such as freelance or business income, monthly SIP is the right choice. You can test each frequency in the advanced panel above.

SIP vs Lumpsum: Which Is Better?

SIP is better for most people because it removes market timing risk and forces discipline. Lumpsum can outperform in a steadily rising market, but few investors time the market correctly and consistently. Compare both side by side with our SIP vs Lumpsum Calculator.

SIP vs Fixed Deposit

For goals 5 or more years away, SIP in equity mutual funds has historically outperformed FDs after inflation and taxes. For goals under 3 years, FDs offer predictability and capital safety that SIPs cannot guarantee. Run the numbers on our FD Calculator.

SIP Taxation in India (FY 2025 to 26)

Each SIP instalment is treated as a separate investment with its own purchase date and holding period.

For equity mutual funds:

• Units held more than 12 months attract Long-Term Capital Gains tax at 12.5%, and gains up to ₹1.25 lakh per year are exempt.
• Units held less than 12 months attract Short-Term Capital Gains tax at 20%.

For debt mutual funds, all gains are added to your income and taxed at your applicable slab rate, regardless of holding period.

For ELSS (Equity Linked Savings Scheme):

• SIP investments up to ₹1.5 lakh per year qualify for deduction under Section 80C.
• There is a 3-year lock-in from each instalment date.
• Gains are taxed as LTCG at 12.5% after the lock-in period.

When you redeem a SIP, each instalment is sold on a First In, First Out basis. Units bought first are sold first, which matters for calculating the holding period on each unit. Plan your tax-saving SIP with our ELSS Calculator.

SIP for NRI Investors

Non-Resident Indians can invest in Indian mutual funds via SIP, subject to FEMA rules.

NRE account SIPs are fully repatriable, and interest earned in NRE accounts is tax-free in India, though it may be taxable in your country of residence. NRO account SIPs suit income earned in India, with repatriation limited to USD 1 million per financial year, and returns taxable in India.

Some fund houses do not accept SIP applications from NRIs in the US or Canada due to FATCA and FBAR compliance. Check with your fund house before you invest. Use the calculator above the same way, entering your monthly amount in INR equivalent, and factor in currency conversion if you plan to repatriate.

SIP and Inflation: Real Returns vs Nominal Returns

The calculator shows nominal returns, the value your investment grows to in future rupees. Due to inflation, ₹1 crore in 2045 will buy less than ₹1 crore buys today.

To find your real return, use this formula.

Real Return = [(1 + Nominal Return) ÷ (1 + Inflation Rate)] − 1

At a 12% nominal return and 6% inflation, your real return is about 5.66% a year.

If your goal is ₹50 lakh in today’s purchasing power over 20 years at 6% inflation, your actual target should be roughly ₹1.60 crore. Always set your SIP target above your current-day goal to account for inflation. Our Inflation Calculator shows exactly how much your goal will cost in future rupees.

Understanding XIRR vs Absolute Return

A common point of confusion. The calculator shows your total corpus and total gain. But your gain percentage is not the same as your annual return.

Because SIP money is invested at different times, each instalment stays invested for a different length of time. Your first instalment compounds for the full tenure. Your last one barely compounds at all. XIRR, or extended internal rate of return, is the measure that accounts for this timing. It is the true annualised return on a SIP.

So a SIP quoting a 12% XIRR does not mean your money doubled in a fixed way. It means each rupee earned an annualised 12% for the period it stayed invested. When you compare funds, compare XIRR, not the simple total gain.

Common SIP Mistakes to Avoid

• Stopping the SIP during a market fall. This is when your money buys the most units. Pausing here locks in the loss.
• Chasing last year’s top fund. Past winners often lag next. Stay with a diversified, consistent fund.
• Using an unrealistic return rate. Planning a critical goal at 18% sets you up to fall short.
• Never increasing the amount. A flat SIP for 20 years ignores your rising income. Use step-up.
• Redeeming early for non-emergencies. Breaking a long SIP interrupts compounding at its most powerful stage.

Expert Tips to Get More From Your SIP

• Automate the SIP on your salary date, so you invest before you spend.
• Enable a 10% annual step-up and treat it as a default, not an option.
• Keep separate SIPs for separate goals, so tracking stays clean.
• Review once a year, not once a week. SIP rewards patience, not tinkering.
• Increase the SIP with every raise and bonus, even by a small amount.
