How Much SIP Do I Need for ₹1 Crore? (10, 15, 20, 25 Years)

The short answer

At an assumed 12% annual return, you need about ₹43,041 a month for 10 years, ₹19,819 for 15 years, ₹10,009 for 20 years or ₹5,270 for 25 years to reach ₹1 crore. At a more cautious 10%, the amounts rise to ₹48,414, ₹23,928, ₹13,060 and ₹7,474. Time does most of the work, so starting earlier matters more than the exact amount. Test your own numbers in the SIP Calculator.

The monthly SIP needed for ₹1 crore

These figures assume a fixed annual return, a fixed monthly amount and the investment made at the start of each month. Mutual fund returns are not fixed or guaranteed, so treat every number below as an estimate, not a promise.

Years	SIP at 12%	Total invested	SIP at 10%	Total invested
10	₹43,041	₹51.6 lakh	₹48,414	₹58.1 lakh
15	₹19,819	₹35.7 lakh	₹23,928	₹43.1 lakh
20	₹10,009	₹24.0 lakh	₹13,060	₹31.3 lakh
25	₹5,270	₹15.8 lakh	₹7,474	₹22.4 lakh
30	₹2,833	₹10.2 lakh	₹4,387	₹15.8 lakh

Read across the 12% column and the pattern is clear. Moving from a 10-year to a 20-year horizon cuts the monthly amount by more than three quarters, and you put in less than half as much of your own money. The rest of the ₹1 crore is growth.

How the calculation works

A SIP is a series of equal monthly payments that each grow for a different length of time. The future value of such a series, with each payment made at the start of the month, is:

FV = P × [((1 + i)^n − 1) ÷ i] × (1 + i)

• P is the monthly SIP amount.
• i is the monthly rate: the annual return ÷ 12 ÷ 100. At 12%, i = 0.01.
• n is the number of months: years × 12.

To find the SIP needed for a target, rearrange it:

P = Target ÷ ([((1 + i)^n − 1) ÷ i] × (1 + i))

Worked check: ₹1 crore in 15 years at 12%

i = 12 ÷ 12 ÷ 100 = 0.01, and n = 15 × 12 = 180.

(1.01)^180 is about 5.996, so ((1.01)^180 − 1) ÷ 0.01 is about 499.6.

Multiply by 1.01 to get about 504.6.

₹1,00,00,000 ÷ 504.6 ≈ ₹19,819 a month.

The SIP Calculator uses the same monthly-compounding method, so you can confirm results there.

Checking a plan in the calculator

The calculator's monthly SIP slider moves in steps of ₹500, so round the amount up to the next step and confirm it clears the target:

Open the SIP Calculator.

Set Monthly SIP to ₹20,000.

Set Expected return to 12% and Investment period to 15 years.

Leave Annual step-up at 0%.

Read the Expected corpus: about ₹1.01 crore, from ₹36 lakh invested.

A few more combinations you can check the same way, all at 12% unless stated:

Monthly SIP	Years	Expected corpus	Invested
₹43,500	10	₹1.01 crore	₹52.2 lakh
₹20,000	15	₹1.01 crore	₹36 lakh
₹10,000	20	₹99.9 lakh	₹24 lakh
₹5,500	25	₹1.04 crore	₹16.5 lakh
₹24,000 at 10%	15	₹1.00 crore	₹43.2 lakh

Notice that ₹10,000 a month for 20 years at 12% lands just under ₹1 crore. Small differences in the assumed return or the start date decide whether a plan crosses a round-number target, so build in some margin.

Choosing a sensible return assumption

The return you type in drives the whole answer. Two habits keep the estimate honest:

• Run more than one rate. Check 10% and 12% at least, and see whether the plan still works at the lower number. If it only works at the higher one, the plan depends on good luck.
• Match the rate to the investment. Equity funds, hybrid funds and debt funds behave very differently. A rate that might be reasonable to test for a long-term equity fund is not reasonable for a short-term debt fund.

Past returns of any fund do not guarantee future returns, and a SIP can lose money over shorter periods.

₹1 crore in the future is not ₹1 crore today

Inflation reduces what a fixed sum buys. If prices rise 6% a year (an assumption for illustration), ₹1 crore received later buys roughly what these amounts buy today:

₹1 crore received after	Today's buying power at 6% inflation
10 years	₹55.8 lakh
15 years	₹41.7 lakh
20 years	₹31.2 lakh
25 years	₹23.3 lakh

If your goal is "enough to cover a cost that costs ₹1 crore today", the real target in 20 years is far higher than ₹1 crore. Decide whether your target is in today's money or future money before you pick a SIP amount.

If the monthly amount is too high

• Extend the period. Going from 15 to 20 years cuts the 12% requirement from ₹19,819 to ₹10,009.
• Increase the SIP every year. A step-up SIP starts lower and rises with your income. At 12% with a 10% yearly increase, a starting SIP of about ₹11,516 reaches ₹1 crore in 15 years. See Step-Up SIP: How Much More Does a Yearly Increase Build?.
• Add lump sums. Bonuses invested when they arrive shorten the path, though the calculator models only the monthly SIP.

Common mistakes

• Using one optimistic rate. A plan that needs 15% every year is fragile.
• Stopping during a market fall. The table assumes every instalment is paid on time. Missed months, especially early ones, lower the result.
• Ignoring tax and costs. Expense ratios are already reflected in a fund's returns, but tax on gains when you redeem is not included in any SIP calculator result.
• Treating the estimate as a guarantee. The calculator shows what happens at a constant return; real returns move up and down from year to year.
