A SIP calculator is a tool that takes your basic investment plan inputs, such as the monthly amount, expected returns, and time horizon, and determines the future value of your parked wealth in mutual funds and other products. Instead of guessing how much your money will grow in 10 or 15 years, you get precise, data-backed information that removes the guesswork from financial planning, ensuring you invest exactly what is estimated to hit your life goals without stressing your monthly budget.

See how market drops can work in your favor. With rupee cost averaging, your SIP buys more mutual fund units at lower prices.
Understand how your investments grow over time, where returns start generating their own returns.
Compare different SIP amounts (₹3,000 vs ₹5,000) and choose what fits your budget.
Whether it's ₹50 lakhs for a house or any goal, know how much to invest monthly.
See which works better-one-time investment or monthly SIP.
Adjust expected returns to understand real outcomes and plan better.
Increasing your SIP yearly (even ₹1,000) can significantly grow your wealth.
Stay calm during market dips by focusing on long-term growth.
When you set up your actual investment, you'll notice a few variations. Here is what you are actually calculating:
Here is an industry secret that most financial websites won't tell you: most SIP calculators online use lazy math that can inflate your returns.
To calculate your monthly returns, most standard tools divide your expected annual return (say, 12%) by 12, giving you 1% per month. That is simple division, not true compounding. When you compound 1% each month, your actual annual return exceeds 12%, which can result in an inflated final number.
Vestbox does the math right. We use the mathematically accurate geometric compounding formula to find your true monthly rate.
For a 12% expected return, the accurate rate is actually 0.95% per month, not 1%.
We then feed that accurate 0.95% into the standard SIP formula to give you realistic projections →
You don't need to solve this yourself. Just know that when you move the sliders on our calculator, you are seeing mathematically sound, non-inflated data, not the fairy-tale numbers shown by other tools.
Calculators show perfect straight lines. Real markets zig-zag. Here is how SIP performs when things get ugly.
Let's say you plan to invest ₹10,000/month in a Nifty 50 fund.
At Vestbox data, when we back-tested this, the SIP investor's average purchase price was drastically lower. This is why your real-world returns might occasionally look different from the calculator's straight-line projection, but historically, they tend to outperform during volatility.
"The lump sum investor panics. The SIP Investor smiles-because the NAV is cheap."
Let's stop guessing and use hard math. Assume you have ₹12 Lakhs to deploy over 10 years. You can put it in a Bank FD today, invest it all as a lump sum, or spread it as a ₹10,000/month SIP.
A number on a screen is useless unless tied to a real-life goal. Here is how to reverse-engineer your dreams:
TARGET WEALTH
₹1.5 Crores
Roughly ₹15,000/month for 20 years at 12% gets you the magic number.
The Vestbox Hack:
Start with ₹5k and using step-up SIP to outpace inflation automatically.
PURCHASE PRICE
₹15 Lakhs
Invest roughly ₹18,000 month in a hybrid fund to cruise into your driveway.
Strategic Approach:
Become your own bank. Avoid high-interest auto loans by funding your asset through equity growth.
