SIP of Rs 5,000 a Month for 10, 15 and 20 Years
A Rs 5,000 monthly SIP for 10 years puts in Rs 6,00,000 total. At an assumed 10% annual return it grows to about Rs 10.3 lakh; at 20 years the same Rs 5,000 SIP can reach roughly Rs 38.3 lakh at 10%, since most of a long SIP's growth happens in its final years, not its early ones.
A SIP of Rs 5,000 a month for 10 years means you invest Rs 6,00,000 in total. At an assumed 10% annual return, that grows to roughly Rs 10.3 lakh by the end of year 10, Rs 20.9 lakh by year 15, and Rs 38.3 lakh by year 20, since a longer SIP lets compounding work on a much bigger base in its later years.
Rs 5,000 a month: 10, 15 and 20 years compared
These figures use assumed annual returns of 8%, 10% and 12%, compounded monthly, which are illustrative growth rates for comparison only, not a promise of what any mutual fund will actually deliver.
| Duration | Total invested | Maturity at 8% (assumed) | Maturity at 10% (assumed) | Maturity at 12% (assumed) |
|---|---|---|---|---|
| 10 years | Rs 6,00,000 | Rs 9,20,828 | Rs 10,32,760 | Rs 11,61,695 |
| 15 years | Rs 9,00,000 | Rs 17,41,726 | Rs 20,89,621 | Rs 25,22,880 |
| 20 years | Rs 12,00,000 | Rs 29,64,736 | Rs 38,28,485 | Rs 49,95,740 |
These are calculated figures based on the standard SIP future value formula, not quotes from any specific fund or scheme.

The formula behind these numbers
A SIP's maturity value follows this formula: FV = P x [((1 + r)^n - 1) / r] x (1 + r), where P is your monthly instalment, r is the monthly rate of return (annual rate divided by 12, as a decimal), and n is the total number of instalments (years multiplied by 12).
For a worked example: at a 10% assumed annual return, the monthly rate r is 0.10/12, which is about 0.00833. Over 10 years, n is 120. Plugging Rs 5,000, that monthly rate and 120 months into the formula gives the Rs 10,32,760 figure in the table above. See the SIP calculator formula explained for the full derivation and more worked examples.
Why the last few years add so much more
Notice that going from 10 to 15 years, invested capital only grows by 50% (from Rs 6 lakh to Rs 9 lakh), but the maturity value at 10% roughly doubles, from about Rs 10.3 lakh to about Rs 20.9 lakh. This is compounding: the returns earned in early years themselves start earning returns, and that snowballing effect is strongest in the final stretch of a long SIP.
This is also why stopping a SIP early, even by a few years, can cost you more than it looks like on paper. The years you skip are usually the ones doing the most work.
Assumed returns are not guaranteed
These calculations use assumed annual returns of 8%, 10% and 12% purely to illustrate how the numbers move. Mutual fund and SIP returns are market-linked, can be negative in some years, and no scheme guarantees a fixed annual return. Confirm current scheme performance and risk factors with the fund's official documents or a registered financial adviser before investing.
How to use this table for your own goal
- Decide the goal amount you are saving for, and roughly how many years you have.
- Pick a conservative assumed return for planning, rather than the best year a fund has ever had.
- Check which row in the table (or which result in the calculator) gets closest to your goal.
- If the number falls short, increase the monthly amount rather than assuming a higher return will make up the gap.
- Revisit the plan every year or two, since your income, goal amount or timeline may change.
What changes if you invest more than Rs 5,000
The formula scales in a straight line with the monthly amount, so a Rs 10,000 SIP simply doubles every figure in the table above, and a Rs 2,500 SIP halves them. This makes it easy to estimate your own number even without opening a calculator: work out the ratio between your amount and Rs 5,000, then apply that same ratio to whichever row matches your tenure.
What does not scale in a straight line is the duration. Going from 10 to 20 years does not simply double the maturity value, it more than triples it at every assumed return in the table, because the extra 10 years are compounding on top of an already larger base. This is the core reason financial planning generally favours starting early over investing a larger amount later.
SIP versus a lump sum, in short
A SIP spreads your investment across many months, which means you buy units at different price levels over time rather than committing everything on one date. This does not change the compounding math shown above once the money is invested, but it does reduce the risk of investing a large lump sum right before a market downturn, since only a fraction of your total goes in on any single day.
If you are comparing a SIP against paying off a loan faster instead, the EMI formula with an example shows the other side of that same compounding logic, since a loan's interest works against you the same way a SIP's returns work for you.
Checklist before you commit to a SIP amount
- Use a return assumption you would be comfortable with even in a below-average year, not the best case.
- Remember the invested amount is fixed and known; the maturity value is an estimate, not a guarantee.
- Increasing your SIP amount by a fixed percentage each year (a "step-up" SIP) can close a shortfall faster than waiting for higher returns.
- Do not withdraw mid-way for a short-term need if you can avoid it, since the compounding benefit shown above depends on staying invested for the full period.

Frequently asked questions
How much does a Rs 5,000 SIP for 10 years become?
You invest Rs 6,00,000 in total over 10 years. At an assumed 10% annual return, it grows to about Rs 10,32,760; the actual figure depends on the fund's real returns, which vary year to year.
Is a 12% annual return realistic for a SIP?
It is one of several assumptions used for illustration in this table, not a guaranteed or typical figure. Actual mutual fund returns vary by scheme, market conditions and time period, and can be lower or negative in some years.
What is the difference between invested amount and maturity value?
Invested amount is simply the total of all your monthly instalments added up. Maturity value is what that money grows to after returns compound over the SIP's duration, and the difference between the two is your gain.
Does a longer SIP always give a much bigger result?
Yes, disproportionately so, because compounding accelerates in the later years of a SIP. Doubling your tenure from 10 to 20 years grows the invested amount by only 2x but can grow the maturity value by significantly more, depending on the assumed return.
Can I increase my SIP amount later?
Yes, most mutual fund platforms let you increase your SIP instalment or set up an automatic yearly step-up, which can help you reach a goal faster than keeping the amount fixed.
