The EzyToolz SIP Calculator estimates the future value of your mutual fund investments made through a Systematic Investment Plan. Enter your monthly SIP amount, expected annual return rate, and investment duration — the tool instantly shows your total invested amount, wealth gained, and projected maturity value, along with an investment breakdown chart and growth projection.

The calculator also supports lumpsum investment calculations and an annual step-up SIP option, where your monthly investment amount increases by a fixed percentage each year — a strategy commonly used to match income growth with investment growth.

How to Use the SIP Calculator

Step 1 — Choose SIP or Lumpsum tab: Select SIP for monthly investment calculations, or Lumpsum for a one-time investment.

Step 2 — Enter monthly investment amount: For SIP, enter how much you plan to invest each month. Minimum ₹500 for most mutual funds.

Step 3 — Set expected return rate: Use 10–12% for equity mutual funds (conservative estimate), 12–15% for aggressive equity, and 6–8% for debt funds.

Step 4 — Set investment duration: Enter number of years you plan to stay invested. The longer the duration, the more compounding works in your favor.

Step 5 — Enable step-up (optional): Toggle the Annual Step-Up option and enter a percentage — typically 5–15% — to simulate increasing your SIP amount each year.

Step 6 — View results: Total Investment, Wealth Gained, Future Value, and Absolute Returns are shown instantly along with charts.

SIP Formula

The calculation behind SIP returns is based on the future value of annuity formula:

FV = P × [(1 + r/n)^(n × t) – 1] × (1 + r/n) / (r/n)

  Where:
  FV = Future Value of the investment
  P = Amount invested through SIP
  r = Expected annual rate of return
  n = Number of compounding periods in a year
  t = Total investment duration in years

SIP Returns — Quick Reference at 12% Annual Return

Monthly SIP	5 Years	10 Years	15 Years	20 Years
₹1,000	₹81,104	₹2,24,036	₹4,75,931	₹9,19,857
₹3,000	₹2,43,311	₹6,72,108	₹14,27,794	₹27,59,572
₹5,000	₹4,05,518	₹11,20,179	₹23,79,657	₹45,99,287
₹10,000	₹8,11,036	₹22,40,359	₹47,59,314	₹91,98,574
₹25,000	₹20,27,590	₹56,00,897	₹1,18,98,285	₹2,29,96,434

Returns are estimated at 12% p.a. compounded monthly. Actual returns depend on fund performance and market conditions.

Step-Up SIP vs Regular SIP — The Difference

A step-up SIP (also called a top-up SIP) increases your monthly investment by a fixed percentage each year. The impact on the final corpus is significant, especially over longer periods.

Example — ₹5,000/month SIP at 12% for 15 years:

Type	Total Invested	Maturity Value	Wealth Gained
Regular SIP	₹9,00,000	₹23,79,657	₹14,79,657
Step-Up SIP (10% annual)	₹19,06,349	₹41,37,359	₹22,31,010

By increasing your SIP by ₹500 every year (10% of ₹5,000), you invest ₹10.06 lakh more but the final corpus jumps from ₹23.80 lakh to ₹41.37 lakh — significantly higher wealth creation through the power of step-up compounding.

SIP vs Lumpsum — When to Choose Which

SIP is better when: You have a regular monthly income and want to invest consistently without worrying about market timing. SIP gives you rupee cost averaging — you automatically buy more units when markets are down and fewer when markets are up, which lowers your average cost per unit over time.

Lumpsum is better when: You have a large one-time amount — a bonus, inheritance, or FD maturity — and markets are at a reasonable valuation. At 12% annual return, ₹5 lakh invested as lumpsum for 10 years becomes approximately ₹15.52 lakh, whereas ₹5 lakh spread as ₹4,167/month SIP for 10 years becomes approximately ₹9.64 lakh.

Use this calculator’s Lumpsum tab to compare both scenarios for your specific amount and duration.

Frequently Asked Questions

At 12% annual return, a ₹5,000 monthly SIP over 10 years grows to approximately ₹11.20 lakh. Total amount invested is ₹6 lakh and wealth gained is ₹5.20 lakh — an absolute return of about 86.7%. At a more conservative 10% return, the same SIP gives approximately ₹10.07 lakh.

At 12% annual return, you need approximately ₹21,011 per month to accumulate ₹1 crore in 15 years. At 15% return, the required monthly SIP drops to around ₹16,224. Use the calculator above and adjust the SIP amount until the Future Value shows ₹1,00,00,000.

For diversified equity mutual funds (large-cap, index funds), a conservative estimate of 10–12% p.a. is commonly used for planning purposes. For mid-cap or small-cap funds, 12–15% is often used. For debt mutual funds, 6–8% is more realistic. These are estimates — actual returns vary by fund, market conditions, and investment horizon.

A step-up SIP automatically increases your monthly investment by a fixed percentage each year. If you start with ₹5,000/month and set a 10% annual step-up, your SIP becomes ₹5,500 in year two, ₹6,050 in year three, and so on. This mirrors income growth and significantly improves the final corpus without requiring a large starting investment. Most mutual fund platforms in India — Zerodha Coin, Groww, Kuvera — support step-up SIPs.

SIP in equity mutual funds carries market risk — the value of your investment can go up or down depending on market performance. However, staying invested for 10 years or longer has historically provided positive real returns in Indian equity markets. SIP also reduces timing risk through rupee cost averaging. For capital preservation, debt mutual funds or hybrid funds are safer options. Mutual fund investments are not insured or guaranteed.

Yes — SIPs in open-ended mutual funds can be paused or stopped at any time without penalty. You can also redeem (withdraw) your accumulated units partially or fully, subject to exit load (typically 1% if redeemed within 1 year for equity funds) and applicable capital gains tax. ELSS (tax-saving) funds have a mandatory 3-year lock-in period and cannot be redeemed before that.

At 12% annual return, a ₹10,000 monthly SIP over 20 years grows to approximately ₹91.99 lakh. Total amount invested is ₹24 lakh and wealth gained is ₹67.99 lakh — an absolute return of about 283%. This is the power of long-term compounding — staying invested longer matters more than increasing the SIP amount.
