How to use this SIP calculator
- Choose how you invest: a monthly SIP or a one-time lump sum.
- Enter the monthly SIP amount (or the lump sum), the expected return a year and the investment period.
- Open "More options" to raise your SIP each year with a step-up, or change the inflation rate used for today's money.
- Read the result. You see the estimated value, the total invested, the estimated returns, the value in today's money and a year-by-year table.
The SIP formula
FV = P × ((1 + i)n − 1) ÷ i × (1 + i) P is the monthly SIP, i the monthly rate (yearly return ÷ 12 ÷ 100) and n the number of monthly instalments. Each instalment is invested at the start of the month.
Worked example
You invest ₹10,000 a month for 10 years and assume 12% a year. The monthly rate is 1%, and there are 120 instalments. The estimated value is ₹23,23,391: ₹12,00,000 you put in and ₹11,23,391 of estimated returns, or 1.94 times your money.
If you raised the SIP by 10% every year, the final year's SIP would be ₹23,579 a month, you would invest ₹19,12,491 in total and the estimated value would reach ₹33,74,326. At a more cautious 9%, the plain ₹10,000 SIP would reach ₹19,49,656.
SIP value by amount and period
Estimated values at 12% a year:
| Monthly SIP | 10 years | 15 years | 20 years |
|---|---|---|---|
| ₹5,000 | ₹11,61,695 | ₹25,22,880 | ₹49,95,740 |
| ₹10,000 | ₹23,23,391 | ₹50,45,760 | ₹99,91,479 |
| ₹25,000 | ₹58,08,477 | ₹1,26,14,400 | ₹2,49,78,698 |
Time does most of the work. A ₹10,000 SIP is worth about ₹23.2 lakh after 10 years but nearly ₹1 crore after 20, although you only invest twice as much. Starting five years earlier often matters more than investing more. For any amount from ₹500 to ₹50,000 a month, the SIP returns by amount pages give the full table by period and return, a 10% step-up and the time to reach ₹1 crore.
Returns are estimates, not promises
Mutual fund returns are market-linked. They are not guaranteed, they vary from year to year and they can be negative for a while. The calculator uses one steady average return so you can see the scale of what is possible, so always run a lower figure too: over 20 years, the same ₹10,000 SIP reaches about ₹99.9 lakh at 12% but ₹67.3 lakh at 9%. Read the scheme documents before you invest.
Gains on mutual funds are taxed as capital gains, at rates that depend on the type of fund and how long you hold it, so the values here are before tax.
In today's money
A crore in 20 years won't buy what a crore buys now. The calculator also shows the final value in today's rupees, using 4% inflation by default, the RBI's target for CPI inflation. The ₹23,23,391 in the example is worth about ₹15,69,600 at today's prices. See how prices add up with the inflation calculator.
SIP, PPF, FD or RD?
A SIP suits long-term goals where you can ride out ups and downs. For guaranteed, tax-free growth, compare the PPF calculator; for fixed bank returns, the FD and RD calculators. To check whether your saving is on track for retirement, use the retirement corpus calculator.
