Free SIP Calculator with Step-Up – Calculate Maturity Amount, Returns & More (2026)

Frequently Asked Questions

• What is SIP and how does it work?

  SIP (Systematic Investment Plan) is a method of investing a fixed amount in a mutual fund at regular intervals — typically monthly. Each instalment buys units at the current NAV, averaging out your cost over time (rupee cost averaging). The power of SIP comes from compounding: your returns earn further returns each period, growing your corpus exponentially over long durations.

• How is SIP maturity value calculated?

  SIP maturity is calculated using the compound interest formula applied month by month: FV = P × [(1 + r)^n – 1] / r × (1 + r), where P is the monthly investment, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of months. For step-up SIPs, the monthly amount increases periodically and the formula is applied iteratively for each period.

• What is Step-Up SIP and how does it help?

  Step-Up SIP (also called Top-Up SIP) increases your monthly SIP amount by a fixed percentage each year. For example, if you start with ₹5,000/month and set a 10% step-up, your SIP becomes ₹5,500 in year 2, ₹6,050 in year 3, and so on. This allows your investment to grow alongside your income, significantly boosting your final corpus compared to a flat SIP.

• What annual return rate should I assume for SIP calculations?

  For equity mutual funds (large-cap, flexi-cap, index funds), a 10–14% annual return is commonly assumed for long-term projections. Index funds tracking Nifty 50 have historically averaged 12–13% over 10+ year periods. For debt funds, 6–8% is more realistic. The calculator uses a fixed rate; actual returns vary with market conditions.

• Is SIP better than lump sum investment?

  SIP is generally better for salaried investors who have a monthly income stream. It eliminates the need to time the market and uses rupee cost averaging — you buy more units when prices are low and fewer when prices are high. Lump sum can outperform SIP in steadily rising markets, but SIP reduces risk and is more accessible for most investors.

• How does compounding benefit SIP investors?

  Compounding means your investment returns earn further returns over time. In SIP, each monthly instalment starts compounding from the day it is invested. Early instalments compound the longest and contribute the most to your final corpus. This is why starting a SIP at age 25 instead of 35 can result in 3–4× more wealth by retirement, even with the same monthly amount.

• What is CAGR in the context of SIP?

  CAGR (Compound Annual Growth Rate) represents the annual rate at which your investment grew. For SIP, the relevant metric is XIRR (Extended Internal Rate of Return), which accounts for the timing of each instalment. The expected annual return you enter in the calculator is the assumed CAGR of the mutual fund. The absolute return shown (returns ÷ invested × 100%) tells you your total gain on invested capital.

• How much SIP do I need to accumulate ₹1 crore?

  At 12% annual return: to accumulate ₹1 crore in 20 years, you need approximately ₹10,000/month. In 15 years, you need ₹20,000/month. In 10 years, approximately ₹44,000/month. Starting a Step-Up SIP with 10% annual increase from ₹7,000/month at 12% for 20 years can also reach ₹1 crore. Use this calculator to find your exact number.

• Should I continue my SIP when markets are falling?

  Yes — continuing SIP during market downturns is one of the best strategies. When markets fall, your fixed monthly SIP amount buys more units at lower NAV prices. When markets recover, these cheaply acquired units generate higher returns. Many investors who paused SIPs during crashes missed the recovery gains. Long-term SIP discipline consistently outperforms market timing.

• Can I change my SIP amount over time?

  Yes. Most mutual fund platforms allow you to modify your SIP amount at any time. You can increase it (use the step-up feature), decrease it, pause it for a few months, or switch to a different fund. The step-up SIP feature in this calculator models automatic annual increases, which is the most effective way to grow your corpus alongside your income.

• What happens to SIP if I stop payments?

  If you miss SIP instalments, only that instalment is skipped — your existing invested units remain and continue to earn returns. Most AMCs allow 2–3 missed instalments before auto-cancellation. You can restart the SIP anytime. The accumulated corpus keeps growing even if you pause, since it remains invested in the mutual fund.

• Is this SIP calculator free to use?

  Yes, completely free. This SIP calculator requires no signup, no registration, and no subscription. All calculations happen instantly in your browser. Results are not stored anywhere. You can use it as many times as you like to plan different SIP scenarios.
