Step-up SIP Calculator with Inflation

Step-up SIP Calculator with Inflation Adjustment

As incomes rise over time, it makes sense to increase SIP contributions annually. This is known as a Step-up SIP. But while your contributions grow, it’s equally important to understand how inflation might eat into your gains. The Step-up SIP Calculator with Inflation helps you assess the real value of your investments by factoring in both the step-up percentage and inflation rate.

What is a Step-up SIP?

A Step-up SIP is a type of mutual fund investment where your monthly SIP increases annually by a fixed percentage. It aligns your investments with income growth and inflation, helping you accumulate a larger corpus over time.

How to Use the Step-up SIP Calculator with Inflation?

• Enter your starting monthly SIP amount.
• Input the annual step-up percentage (e.g., 10%).
• Select the investment period in years.
• Provide the expected annual return.
• Enter the inflation rate (optional).

Features

• Supports annual SIP increase percentage.
• Calculates both total investment and future value.
• Inflation-adjusted figures for realistic planning.
• Visual bar chart for easy comparison.

Formula Used

Calculations are based on compounding future value for each year’s increasing SIP amount:

Each year’s contribution is calculated separately using:

FV = P × (1 + r)^(n - year)

and adjusted for inflation.

Advantages

• Perfect for investors expecting annual income hikes.
• Combines the power of compounding with increased contributions.
• Provides a clearer picture of the real future value.

Start with ₹5,000 monthly SIP, increase by 10% yearly, invest for 15 years at 12% return with 6% inflation. You might build a nominal corpus of ₹43 lakhs, but its real value would be around ₹27 lakhs (approx) in today’s terms.
