SIP Calculator Masterclass

Learn how to use the SIP Calculator to plan your investments, understand the power of compound growth, step-up strategies, and inflation-adjusted returns.

1. SIP Calculator Basics

A Systematic Investment Plan (SIP) allows you to invest a fixed amount regularly (monthly) in mutual funds. Our calculator helps you project future value based on your investment parameters.

Input Parameters Explained

Monthly SIP Amount

The fixed amount you'll invest every month. Start with what you can afford consistently.

Example: ₹10,000/month

Expected Annual Return

Projected yearly return based on fund category. Be realistic - see section 4 for guidance.

Example: 12% for Flexi Cap funds

Investment Duration

How long you'll continue the SIP. Longer duration = more compound growth.

Example: 20 years for retirement planning

The Power of Compound Growth

SIP leverages rupee-cost averaging and compound interest. Here's a real example:

Monthly SIP

₹10,000

Total Invested (20Y)

₹24 Lakh

Future Value @ 12%

₹99.9 Lakh

Returns: ₹75.9 Lakh (316% gain!)

2. Step-Up SIP Strategy

A step-up SIP automatically increases your monthly investment by a fixed percentage every year. This aligns with salary increments and dramatically boosts long-term wealth.

How Step-Up Works

Year 1:
₹10,000/month
Year 2:
₹11,000/month (10% step-up)
Year 3:
₹12,100/month (10% step-up)
Year 20:
₹56,044/month

Step-Up Impact Example

Same ₹10,000 starting SIP, 20 years, 12% returns:

Without Step-Up (Fixed SIP)

₹99.9 Lakh

Investment: ₹24L

With 10% Step-Up

₹2.29 Crore

Investment: ₹73L

💡 Additional Wealth Created: ₹1.29 Crore (129% more!)

Recommended Step-Up Percentage

5% Step-Up: Conservative

Matches average salary hikes. Easy to sustain.

10% Step-Up: Recommended

Optimal balance - aligns with career growth and inflation.

15% Step-Up: Aggressive

For high earners with strong career trajectory.

3. Understanding Inflation Adjustment

Inflation erodes purchasing power. Our calculator shows real returns - what your money will actually be worth in today's terms after accounting for inflation.

What are Inflation-Adjusted Returns?

Nominal Returns: The absolute rupee value you'll have (without considering inflation)

Real Returns: The actual purchasing power of your money in today's terms

Example:

• Future value after 20 years: ₹1 Crore

• Inflation @ 6% for 20 years = 3.21x increase in prices

• Real purchasing power: ₹31.2 Lakh in today's money

This means ₹1 Crore in 20 years buys what ₹31.2 Lakh buys today.

How We Calculate Real Returns

Unlike simple calculators that just deflate final value, we use a sophisticated approach:

  1. Each monthly contribution is tracked individually
  2. Growth is calculated with compound interest month-by-month
  3. Each contribution is deflated from its end value back to present value
  4. Sum of all deflated contributions = Real purchasing power

✨ This gives you the TRUE purchasing power of your returns, accounting for when each rupee was invested.

What Inflation Rate to Use?

4-5%
Conservative estimate (historical average in India)
6%
Recommended for long-term planning (realistic)
7-8%
Pessimistic scenario (factor in lifestyle inflation)

4. Expected Returns Guide

Setting realistic return expectations is crucial. Here are historical category-wise returns to guide you:

High Return Potential

Small Cap14-16%
Mid Cap13-15%
Flexi/Multi Cap12-14%

Moderate Returns

Large Cap10-12%
Index Funds11-13%
International9-11%

Conservative

Hybrid Funds8-10%
Debt Funds6-8%
Gold Funds7-9%

High Risk

Thematic/Sector12-16%
(Highly volatile)±20-30%

💡 Pro Tip: Use 12% for balanced equity portfolios. Be conservative - it's better to be pleasantly surprised than disappointed!

5. Interpreting Results

Understanding the Output

Total Investment

Sum of all your monthly contributions over the period.

Future Value (Nominal)

The absolute rupee value you'll have - what your statement will show.

Total Returns

Future Value - Total Investment = Your profit/gain

Real Returns (Inflation-Adjusted)

The TRUE purchasing power gain. This is what matters for real wealth creation.

Using Results for Planning

  • For retirement planning: Focus on inflation-adjusted returns. You need real purchasing power.
  • For goal-based investing: If goal is 15+ years away, use 6% inflation minimum.
  • For short-term goals (< 5 years): Use conservative return estimates (8-10%).
  • Review yearly: Adjust SIP amounts based on actual returns and life changes.
