How Does the Step-Up SIP Calculator Work?

A Step-Up SIP (also known as a Top-Up SIP) automatically increases your monthly mutual fund investment by a predetermined percentage (e.g., 10%) every year. As your income and career advance with annual increments, stepping up your monthly contributions leverages the exponential snowball effect of compounding.

Even a modest 10% yearly increase in your SIP can nearly double your final wealth accumulation compared to a standard fixed SIP over a 15-to-20 year investment horizon.

Formula & Mathematical Methodology

The maturity value calculates each annual cohort compounded forward to the target tenure:

Maturity = ∑ [ Pyr × (((1 + r)nyr - 1) / r) × (1 + r) ]

Where Pyr increases annually by your chosen step-up percentage (e.g. Pyr+1 = Pyr × (1 + g)), and r is the monthly expected return rate.

Step-by-Step Practical Calculation Example

Starting with ₹10,000/month for 15 years at 12% p.a.:

  • Fixed Regular SIP: Invested ₹18 Lakh → Maturity ₹50.45 Lakh
  • 10% Annual Step-Up SIP: Invested ₹38.12 Lakh → Maturity ₹88.58 Lakh
  • Extra Wealth Created: +₹38.13 Lakh through disciplined annual increments!
