Example
Invest ₹10,000 every month for 10 years at an expected return of 12% a year. The monthly rate is 12 ÷ 1200 = 1%, and you make 120 instalments. You put in ₹12,00,000 in total, and the projected maturity value is about ₹23,23,391 — roughly ₹11,23,391 of estimated returns on top of what you invested.
How it works
Let i = annual rate ÷ 1200 (the monthly rate as a decimal) and n = years × 12. Each instalment is assumed to be invested at the start of the month, so the maturity value uses the annuity-due formula most Indian SIP calculators follow: FV = p × ((1+i)^n − 1) ÷ i × (1+i). Invested amount = p × n, and estimated returns = FV − invested. If the rate is 0, the maturity value is simply p × n.
Good to know
A SIP, or systematic investment plan, is a standing instruction to invest a fixed amount into a mutual fund scheme at a regular interval — usually monthly, debited automatically from your bank account. It is not a product in itself but a way of buying fund units gradually instead of in one lump sum. SIPs can start from as little as ₹500 a month with most fund houses, can be paused or stopped without penalty in open-ended funds, and are the most common way Indian retail investors hold equity mutual funds.
Investing a fixed rupee amount each month means you automatically buy more units when the market falls and fewer when it rises — this is rupee-cost averaging. It does not guarantee a profit, but it smooths your purchase price across market cycles and removes the temptation to time entries. The second engine is compounding: in the example above, the estimated returns (₹11,23,391) are almost as large as the amount invested (₹12,00,000), and the gap widens sharply with longer tenures — the same SIP over 20 years grows to roughly ₹1 crore because earlier gains keep earning.
Treat the return figure as an assumption, not a promise. 12% is a common planning number for equity funds based on long-run index history, but actual returns vary widely by scheme, entry point and period — debt funds may earn 6–8% while equity can swing far in either direction over short spans. Rerun the calculation at 8% and 10% to see a conservative range. Many investors also use a step-up (top-up) SIP, raising the instalment by, say, 10% each year in line with salary growth; even modest annual increases compound into a substantially larger corpus than a flat SIP.
Taxes apply when you redeem, not while you invest. For equity-oriented funds, long-term capital gains (units held over a year) above ₹1.25 lakh in a financial year are taxed at 12.5%, and each SIP instalment has its own holding period for this purpose. This calculator shows pre-tax, pre-inflation values and ignores expense ratios beyond what your assumed return already reflects — verify scheme-specific details in the fund's offer document before investing.
Frequently asked questions
What is a SIP and how does this calculator work?
A SIP (systematic investment plan) invests a fixed amount into a mutual fund every month. The calculator compounds each instalment at your expected annual rate (converted to a monthly rate) until the end of the period, assuming instalments at the start of each month, and shows the invested amount, estimated returns and maturity value.
Is 12% a realistic SIP return?
12% is a common long-run planning assumption for diversified equity funds, not a guarantee. Actual returns depend on the scheme, market conditions and your holding period — they can be higher or lower, and can be negative over short spans. Test 8% and 10% as conservative scenarios.

People also ask
How much will a ₹10,000 monthly SIP grow to in 10 years?
At an assumed 12% annual return, ₹10,000 a month becomes about ₹23.2 lakh in 10 years — ₹12 lakh invested plus roughly ₹11.2 lakh of estimated returns. At 10% it is about ₹20.7 lakh. The outcome depends entirely on the return your fund actually delivers.
What is rupee-cost averaging in a SIP?
Because you invest a fixed rupee amount every month, you automatically buy more fund units when prices are low and fewer when they are high. Over time this averages your purchase cost across market ups and downs, though it does not guarantee a profit.
Are SIP returns tax-free?
No. For equity funds, long-term capital gains above ₹1.25 lakh per financial year are taxed at 12.5% when you redeem, and each instalment has its own holding period. Short-term gains and debt-fund gains are taxed differently, so check the current rules before redeeming.
