If I invest ₹1K monthly for 25 years, why is the real corpus only ₹7.22 L?

Investing ₹1K every month for 25 years adds up to ₹3 L in total contributions. At a 10% return, compounding yields a nominal nest egg of ₹13.38 L. However, factoring in an annual inflation rate of 2.5%, the real buying power of that corpus drops to ₹7.22 L in today's money.

What are the total compound gains of my SIP of ₹1K monthly?

Your total investments equal ₹3 L. The nominal value grows to ₹13.38 L, resulting in total gains of ₹10.38 L. After accounting for inflation, your real wealth gains are ₹4.22 L.

Why should I look at inflation-adjusted SIP values?

Standard SIP calculators show a massive future balance, but over 20-30 years, inflation cuts purchasing power significantly. Knowing the real value helps you invest enough to reach your actual goals.

Calculation Methodology & Formulas

The Systematic Investment Plan (SIP) compounds monthly:

FV_nominal = P × [((1 + r_m)ⁿ - 1) / r_m] × (1 + r_m)

Real Value = FV_nominal / (1 + i)^y

Where: P = monthly installment, r_m = monthly interest rate (r/12/100), n = total months (y × 12), i = annual inflation rate, and y = duration in years.
