SIP Calculator with Step-Up
A SIP (Systematic Investment Plan) lets you invest a fixed amount in a mutual fund every month. This calculator estimates what your SIP could grow to, based on your monthly contribution, the expected annual return, and how long you stay invested - so you can plan goals like a home, education or retirement.
The amount you invest every month.
Increase the monthly amount by this much every year. Set 0 for a level SIP.

Long-term equity mutual funds have historically returned 10–14%.

How to calculate SIP returns
Each monthly contribution is invested and then compounds month after month. Because earlier contributions have more time to grow, the final value is far larger than the total you put in - that is the power of compounding. This calculator assumes contributions are made at the start of each month and that returns compound monthly.
FV = P × [ ((1 + i)ⁿ − 1) / i ] × (1 + i)Example. Investing ₹10,000 per month for 10 years at an expected 12% annual return, your total invested is ₹12,00,000 while the estimated maturity value is about ₹23.2 lakh - roughly ₹11.2 lakh of that is returns.
What return rate should I assume?
Returns depend on the fund category. Diversified equity mutual funds in India have historically delivered around 10–14% annually over long periods, debt funds 6–8%, and hybrid funds in between. Markets fluctuate year to year, so treat the result as an estimate, not a guarantee - use a conservative figure if you want a safety margin.
Why stay invested longer?
Time matters more than amount. Thanks to compounding, the last few years of a long SIP add disproportionately to the corpus. Increasing your tenure - or stepping up your contribution each year - usually has a bigger impact than chasing higher returns.
Frequently asked questions
What is a step-up SIP and how much difference does it make?
A step-up (or top-up) SIP raises the monthly amount by a set percentage every year, so your investing tracks your income instead of staying flat for a decade. The effect is large: 10,000 a month for 10 years at 12% grows to about 23.2 lakh, but stepping it up 10% a year turns the same starting amount into roughly 33.7 lakh - you invest more, and the early increases have the longest to compound.
Why does the calculator show a lower 'worth in today's money'?
Because a rupee in fifteen years buys less than a rupee now. The maturity figure is what the account will say; the real value is what it will buy at the inflation rate you set. Both are true, and planning against only the first is how people end up with a corpus that looks large and falls short.
Is the SIP return guaranteed?
No. Mutual fund returns depend on market performance and are not fixed. This calculator uses a constant expected return to project an estimate; actual returns will vary year to year.
Does this calculator account for taxes?
Not taxes, no. Inflation it does handle - the "worth in today's money" figure is the corpus adjusted by the inflation rate you set. Tax is left out because it depends on your holding period and slab: long-term capital gains on equity funds above the exemption limit are taxable, and short-term gains are taxed differently again.
Lumpsum or SIP - which is better?
A SIP averages your purchase cost over time (rupee-cost averaging) and removes the need to time the market, which suits regular savers. A lumpsum can outperform if invested at the right time. Many investors use both.
