Assumptions and formula
Month by month: each instalment is added and the balance grows at the monthly rate. With instalments at the start of the month this is the familiar P × ((1 + i)ⁿ − 1) ÷ i × (1 + i); at the end of the month the final (1 + i) drops out. The monthly rate is the annual return ÷ 12 by default, the convention most SIP calculators use, or its compounded equivalent if you choose it.
Those two choices are named on the result because they change it: at 12% for 10 years, start-of-month instalments end about 1% higher than end-of-month ones, and the compounded rate ends lower than ÷ 12. A step-up raises the instalment every 12 months. The tax panel treats every instalment as its own purchase with its own 12-month clock: equity-oriented fund gains held 12 months or more are taxed at 12.5% above ₹1.25 lakh, and under 12 months at 20%, plus 4% cess, as if everything is redeemed at the end in one financial year. Expense ratio and exit load are not deducted.
Worked example
₹10,000 a month at 12% for 10 years, paid at the start of each month, grows to ₹23,23,391: ₹12 lakh invested and ₹11.23 lakh of gains. Paid at the end of each month it is ₹23,00,387. Step the SIP up by 10% a year for 15 years and the corpus is about ₹86.8 lakh, against ₹50.5 lakh without the step-up.
Frequently asked questions
What does ₹10,000 a month in a SIP become in 10 years?
About ₹23.2 lakh at a 12% annual return with instalments at the start of each month: ₹12 lakh invested and ₹11.2 lakh of gains. At the end of each month it is about ₹23.0 lakh, and in today’s money at 5% inflation about ₹14.3 lakh.
How is SIP return calculated?
With the future value of a series of monthly payments: P × ((1 + i)ⁿ − 1) ÷ i × (1 + i), where P is the monthly SIP, i the monthly rate and n the number of months. The final (1 + i) is there because each instalment is invested at the start of the month; for end-of-month payments it is dropped. ₹10,000 a month at 12% for 10 years comes to ₹23,23,391 paid at the start of each month, or ₹23,00,387 at the end. It also works as a lumpsum calculator and mutual fund calculator: set the monthly SIP to zero and enter the lump sum to see what a one-time mutual fund investment grows to, with the same tax and inflation figures.
Why do different SIP calculators give different answers for the same inputs?
Because of two assumptions most of them don’t state. One is payment timing: start-of-month instalments earn one more month of growth each, about 1% more at 12%. The other is the monthly rate: dividing 12% by 12 gives 1% a month, while the compounded equivalent is 0.949%, and over 20 years that gap is about 8% of the corpus. This calculator lets you choose both and shows which one it used.
How much tax will I pay on SIP returns?
For an equity-oriented fund, gains on units held 12 months or more are long-term and taxed at 12.5% on the amount above ₹1.25 lakh in a financial year; units held under 12 months are taxed at 20%. Cess of 4% is added. In a SIP every instalment has its own 12-month clock, so if you redeem everything at once, the last year of instalments is still short-term. The tax panel works that out instalment by instalment.
What is a step-up SIP?
A SIP whose monthly amount rises by a fixed percentage every year, usually in line with salary increases. ₹10,000 a month stepped up 10% a year for 15 years at 12% grows to about ₹86.8 lakh, roughly 1.7 times the ₹50.5 lakh a flat ₹10,000 SIP reaches. Enter the step-up percentage to see the year-by-year instalment.
How much SIP do I need for ₹1 crore?
Enter ₹1,00,00,000 as the target and the calculator gives the monthly SIP needed with your return, years and step-up. At 12% with instalments at the start of each month, it is about ₹10,000 a month for 20 years, or about ₹2,830 a month for 30 years. The longer the term, the more of the corpus comes from growth rather than your own money.
Is this a mutual fund SIP calculator or a systematic investment plan calculator?
Both: a SIP is a systematic investment plan, a fixed monthly investment into a mutual fund. This SIP plan calculator projects any SIP investment plan, equity or debt, from the monthly amount, an expected return and the number of years. It cannot predict a particular fund’s return, so treat the return as an assumption and try a cautious one. It is also a SIP return calculator, a SIP investment plan calculator and a step up SIP calculator in one.
Can I use this as a SIP planner?
Yes. It is a SIP planner and MF SIP calculator for any mutual fund: enter the monthly amount, the expected return and the years, add a yearly step-up if you plan to raise it, and see the corpus you would build.
Is this a top up SIP calculator?
Yes. Enter a yearly step-up and it works as a top up SIP calculator, raising the monthly SIP by that percentage every year.
