Calculate the future value of your monthly SIP in mutual funds.
Interactive calculator loads below. JavaScript required for live calculations.
Formula
Future Value (FV) = P × ((1+i)^n − 1) / i × (1+i)
Where P is the monthly investment amount, i is the monthly expected rate of return (annual rate ÷ 12 ÷ 100), and n is the total number of months.
The (1+i) at the end accounts for SIPs being made at the start of each month (annuity due). For end-of-month SIPs (annuity ordinary), drop the trailing (1+i).
Worked Examples
If you invest ₹10,000 per month for 20 years at an expected annual return of 12%: P = 10,000, i = 0.01, n = 240. Future Value ≈ ₹99.9 lakh. Total invested = ₹24 lakh. Wealth gained = ₹75.9 lakh. The same SIP for 25 years grows to ₹1.90 crore — five extra years more than doubles the corpus.
About the SIP Calculator
A Systematic Investment Plan, universally called SIP in India, is the single most important wealth-building tool for the salaried Indian middle class. By investing a fixed amount every month into a mutual fund, you sidestep the impossible problem of market timing, harness the power of compounding, and build a corpus that comfortably outpaces inflation over the long term. This SIP calculator shows you exactly how much your monthly contribution can grow to over five, ten, or thirty years at any expected rate of return.
The Magic of Compounding: Why Time Matters More Than Money
The SIP future-value formula is mathematically a future value of annuity calculation. However, the intuition is simpler: each monthly instalment compounds for a different number of months. Your first SIP instalment compounds for the entire 20-year tenure, while your last one compounds for just 30 days. This is why the 'tail' of your investment journey is where the real wealth is made. A ₹10,000 monthly SIP at 12% for 10 years becomes ₹23 Lakh. The same SIP for 20 years becomes ₹1 Crore. For 30 years, it becomes ₹3.5 Crore. Notice how the last 10 years add ₹2.5 Crore to your wealth, while the first 10 years only added ₹23 Lakh. This is the non-linear magic of compounding.
Rupee Cost Averaging in the Indian Market
Indian markets (Nifty 50, Sensex) are volatile. In a given year, the market can drop 20% or rise 40%. A SIP uses this volatility to your advantage. When markets fall, your fixed monthly amount buys more units of the mutual fund. When markets rise, you buy fewer units. Over time, your average cost of purchase becomes lower than the average market price. This 'Rupee Cost Averaging' ensures you don't need to 'time' the market. In fact, for a long-term SIP investor, a market crash early in the journey is actually a good thing because it allows you to accumulate more units at a 'sale' price.
The Step-Up SIP: The Secret of the Wealthy
Most Indians start with a small SIP but forget to increase it as their salary grows. This is a massive missed opportunity. A 'Step-Up SIP' is where you increase your monthly investment by a fixed percentage (say 10%) every year. If you start a ₹10,000 SIP and increase it by 10% annually, your corpus after 20 years will be roughly ₹1.7 Crore—nearly double the ₹99 Lakh you would have made with a flat SIP. Our calculator allows you to visualize this 'Step-Up' effect, which is the most powerful way to reach your retirement goals faster.
Choosing Between Index Funds, Flexi-Cap, and ELSS
For a beginner in India, a Nifty 50 Index fund is the safest starting point with the lowest fees. Flexi-cap funds allow the manager to invest across large, mid, and small-cap stocks, providing better growth potential but with higher volatility. ELSS (Equity Linked Saving Scheme) funds are specifically for tax-saving under Section 80C, with a 3-year lock-in. Regardless of the fund type, always choose Direct Plans over Regular plans. Direct plans have zero commissions for agents, saving you 0.75-1.25% in fees every year. Over 20 years, this choice alone can result in 15-20% more wealth in your account.
Practical Tips for SIP Success
- Automate: Set up an OTM (One Time Mandate) with your bank so the money is deducted on the 1st or 5th of every month, right after your salary hits.
- Don't Panic: The biggest enemy of SIP returns is the 'Stop' button. Never stop your SIP during a market crash; that is precisely when your future wealth is being built.
- Set Goals: Don't just invest 'for returns.' Assign a goal to every SIP—e.g., 'Child's Education,' 'Retirement,' or 'Dream Home.' This makes it easier to stay disciplined when the market gets choppy.
Frequently Asked Questions
What return rate should I assume for an equity SIP?
For diversified Indian equity mutual funds, a 10-12% long-term return is a reasonable assumption based on Nifty 50 historical data. Use 8-10% for hybrid funds and 6-7% for debt funds.
Are SIP returns guaranteed?
No. Mutual fund returns depend on market performance and are not guaranteed. SIPs reduce timing risk through rupee cost averaging but do not eliminate market risk.
How are SIP returns taxed?
Equity SIP gains over ₹1.25 lakh per year held more than 12 months are taxed at 12.5% (LTCG). Held under 12 months, gains are taxed at 20% (STCG). Each SIP instalment has its own holding-period clock.
What is a step-up SIP?
A step-up SIP increases the monthly investment amount by a fixed percentage every year (usually 5-10%), in line with your salary growth. It can double your final corpus over 20 years compared to a flat SIP.
Can I stop my SIP anytime?
Yes, you can pause or cancel a SIP anytime through your distributor or AMC platform. Stopping a SIP does not redeem your existing units; those continue to remain invested.
