₹10,000 SIP for 10, 15 and 20 Years: What It Could Become

A ₹10,000 SIP for 10 years, invested at the start of every month, comes to ₹12 lakh in deposits. At an assumed 10% a year, it grows to ₹20.15 lakh. Stretch the same SIP to 20 years and the deposits reach ₹24 lakh, while the assumed value at 10% is ₹72.40 lakh.

New to funds? What is a mutual fund? explains the basics first. This article shows only what a fixed monthly amount could become under constant assumed returns.

Deposits and value at three time horizons

Each row assumes ₹10,000 invested at the start of every month for the period shown.

Data note: illustrative figures at assumed constant annual returns, compounded monthly at the equivalent rate. No tax or costs are deducted.

Most of the 20-year value is growth

Over 20 years, the SIP deposits ₹24 lakh. At an assumed 12% a year, the value is ₹91.99 lakh, so ₹67.99 lakh of it is growth rather than money put in. The table below shows the same split at each rate.

Data note: gain is value minus amount invested. Illustrative figures at assumed constant returns, before tax.

Time matters more than the rate

Compare the rows across the two tables. At an assumed 12% a year, 10 years of SIP gives ₹22.40 lakh. At an assumed 8% a year, 20 years gives ₹57.27 lakh. The longer period wins even with the lower rate, because each year's growth is added to a larger base. A higher return helps, but in a monthly SIP the number of years does more of the work.

Constant assumed returns differ from real markets

Every figure here uses a constant annual return. Real equity returns change from year to year, and some years are negative. An average of 12% over a decade can hide sharp falls along the way, and a fall close to a goal can leave the value below what you deposited.

Treat the three rates as a range for testing, not a prediction. The 8% row gives a cautious view, and the 12% row shows what a stronger outcome could look like.

Tax reduces what you keep

The figures are before tax. Equity mutual fund gains are taxed when you redeem, so the amount you keep is lower than the value shown. For units sold on or after 23 July 2024, long-term gains above ₹1.25 lakh in a financial year are taxed at 12.5%, plus surcharge and cess. Short-term gains are taxed at 20%, as of October 2026. Each monthly instalment is a separate purchase, so each batch of units may have its own holding period. How mutual funds are taxed in India sets out the rules for each fund type.

A yearly step-up raises the result

The figures assume the SIP stays at ₹10,000 a month. Increasing the amount each year lifts the outcome. The 20-year flat 12% figure of ₹91.99 lakh matches the flat-SIP baseline in how a SIP step-up works, which covers how a yearly increase changes the result.

Investors a long SIP suits

A 10 to 20 year SIP suits money with no need in the near term, such as savings for a goal far away. Money needed in the next few years is better kept away from equity funds, where a fall can coincide with the withdrawal date. The longer the horizon, the more room the SIP has to absorb weak years.

Frequently asked questions

What does a ₹10,000 SIP for 10 years become?

At an assumed 8% a year, ₹10,000 a month for 10 years is worth ₹18.13 lakh, on deposits of ₹12 lakh. At an assumed 10% it is ₹20.15 lakh, and at 12% it is ₹22.40 lakh. These are constant assumed returns, before tax, so the actual outcome will differ.

What does a ₹10,000 SIP for 20 years give at 12%?

The deposits total ₹24 lakh over 20 years. At an assumed 12% a year, the value is ₹91.99 lakh, a gain of ₹67.99 lakh before tax. Real returns vary from year to year, so this is one possible path rather than an expected outcome.

Is the gain from a SIP taxed when I withdraw?

Yes. Equity mutual fund gains are taxed on redemption. For units sold on or after 23 July 2024, long-term gains above ₹1.25 lakh in a financial year are taxed at 12.5%, plus surcharge and cess, and short-term gains at 20%, as of October 2026. The figures in this article do not deduct tax.
