How to Use a SIP Calculator: Plan Your ₹1 Crore Goal in 3 Steps (2026)

Introduction: The “Crorepati” Dream Without the Lottery
Shankaran Pillai has a dream.
He sits on his veranda in Kallakurichi, sipping filter coffee, calculating on the back of an envelope. He wants to retire with ₹1 Crore. To him, that number sounds impossible. He thinks he needs to win a lottery, sell his ancestral land, or find a pot of gold to reach it.
He is wrong. He doesn’t need a lottery ticket. He just needs a calculator and some discipline.
Most people fail to build wealth not because they lack money, but because they don’t do the math. They guess.
Today, we are going to stop guessing. We will show you exactly how to use a SIP Calculator to reverse-engineer your dream life.
What is a SIP Calculator? (And Why You Need It)
A SIP (Systematic Investment Plan) Calculator is a simple online tool that does complex compounding math for you in seconds.
It answers three critical questions:
- “How much?” (Maturity Amount)
- “How long?” (Duration)
- “What if?” (Scenarios like increasing your investment)
Instead of using complex Excel formulas or trusting a bank agent who might misguide you, you can use our free tool to see the truth yourself.

Step-by-Step: How to Use the SIP Calculator
Let’s help Shankaran plan his retirement. Follow these 3 simple steps on the [Elathi SIP Calculator].
Step 1: Enter Your Monthly Investment (The Sacrifice)
How much can you save? Be realistic.
- Shankaran inputs: ₹10,000
- Tip: Start with what you can afford today. You can always increase it later using a “Step-Up SIP.”
Step 2: Choose Your Expected Return Rate (The Vehicle)
This depends on where you are investing.
- Conservative (Hybrid Fund): 10%
- Moderate (Large Cap Fund): 12%
- Aggressive (Mid/Small Cap Fund): 15%
- Shankaran chooses: 12% (A standard expectation for long-term equity mutual funds).
Step 3: Select the Time Period (The Patience)
Compounding needs time. This is the most important slider.
- Shankaran inputs: 20 Years
The Result:
The calculator instantly shows Shankaran the magic numbers:
- Total Invested: ₹24 Lakhs
- Wealth Gained: ₹75.9 Lakhs
- Total Value: ₹99.9 Lakhs (~1 Crore)
Shankaran stares at the screen. He realizes he doesn’t need a lottery. He just needs to save ₹10,000 a month.
Scenario Analysis: The High Cost of Delay
This is the part that usually shocks people. Let’s use the calculator to see what happens if Shankaran waits just 5 years to start.
| Scenario | Monthly SIP | Interest Rate | Duration | Final Value |
| Start at Age 30 | ₹10,000 | 12% | 30 Years | ₹3.5 Crores |
| Start at Age 35 | ₹10,000 | 12% | 25 Years | ₹1.89 Crores |
| Start at Age 40 | ₹10,000 | 12% | 20 Years | ₹99.9 Lakhs |
The Lesson:
Waiting 10 years didn’t just cost him “time.” It cost him ₹2.5 Crores in lost wealth.
Don’t wait. Check your “Cost of Delay” right now
How to Calculate Inflation-Adjusted Returns
Shankaran is smart. He asks, “But wait! In 20 years, ₹1 Crore won’t buy me a luxury villa. It will barely buy a 2BHK flat!”
He is right. This is why you must calculate Real Returns.
The Formula:
Real Return = Market Return – Inflation Rate
If your SIP gives 12% and inflation is 6%, your Real Growth is 6%.
How to plan for this:
If you need ₹1 Crore in today’s value, you actually need to aim for ₹3 Crores in the calculator to maintain the same lifestyle 20 years from now.
To achieve this, you simply increase your Monthly Investment in the calculator until the result hits ₹3 Crores. (Spoiler: You might need to invest around ₹30,000/month or increase your SIP by 10% every year).
Common Mistakes When Using a SIP Calculator
1. Being Too Optimistic with Returns
Don’t enter “25%” just because the market was good last year. Be conservative. Stick to 12-13% for equity funds. If the market gives more, treat it as a bonus.
2. Ignoring Taxation
Remember that returns over ₹1.25 Lakhs a year are taxed at 12.5%.
- Tip: Our calculator shows the gross value. Mentally deduct ~10% from the profit to see your “in-hand” amount.
3. Forgetting the “Step-Up”
You won’t earn the same salary forever. Your investments shouldn’t stay flat either. Use the calculator to see how adding just ₹500 extra every year changes the game.

Conclusion: Stop Dreaming, Start Calculating
A goal without a plan is just a wish. A goal with a calculator is a strategy.
Shankaran now has a number. He knows that if he skips one dinner outing a month and invests that money, his retirement is secure. The anxiety is gone, replaced by a plan.
Do you have your number yet?
Don’t guess. Don’t hope. Calculate.
