Real SIP Compounding Formula
Calculates the future purchasing power of your SIP corpus by compounding contributions at the inflation-adjusted real rate.
Worked Example: ₹10,000 monthly SIP for 15 years at 12% returns with 6% inflation
Inflation-Adjusted SIP: The Reality Check for Your Future Dreams
Manish was projecting his retirement wealth. A ₹10,000 monthly SIP compounding at 12% over 15 years would grow to ₹50.5 Lakhs. He was confident this would fund his dreams. But his planner suggested adjusting the target for inflation.
At a 6% annual inflation rate, the purchasing power of ₹50.5 Lakhs in 15 years is equivalent to just ₹31.1 Lakhs today. Manish wasn't going to be rich; he was barely going to cover essential living costs. Inflation would silently erode nearly 40% of his future purchasing power.
Inflation is the reduction of purchasing power over time. When planning long-term goals, nominal future values can create a false sense of security. Adjusting your SIP projections for inflation shows the real value of your future wealth in today's terms.
To counter inflation, either increase your monthly SIP amount annually (SIP Top-Up) or target a higher retirement corpus. Always run your numbers with an inflation adjustment (typically 6% for India) to keep your financial planning realistic.
Frequently Asked Questions
What is an inflation-adjusted SIP?
It is a calculation that adjusts your future SIP maturity corpus for inflation, showing you the real purchasing power of your future wealth in today's terms.
Why should I adjust my SIP for inflation?
Inflation erodes purchasing power. A ₹50 Lakhs nominal corpus in 15 years sounds large, but at 6% inflation, its purchasing power is equivalent to just ₹31 Lakhs today. Planning without inflation leads to savings shortfalls.
How does inflation impact retirement planning?
Retirement expenses will rise due to inflation. If you need ₹50,000/month today, you will need ₹1.2 Lakhs/month in 15 years to maintain the same lifestyle. Your target corpus must be inflation-adjusted.
