SWP Math Takeaways
- The Inflation Compounder: With a 6% inflation rate, a ₹50,000 monthly withdrawal grows to ₹89,540 in 10 years, and ₹1,60,350 in 20 years to maintain identical purchasing power.
- Sequence of Returns Risk: Drawing down capital while the underlying markets fluctuate can accelerate depletion if returns are poor in the early years. Keeping returns conservative helps buffer this.
- Safe Withdrawal Rate (SWR): Standard retirement research recommends a SWR of 4% of the initial capital to ensure your money lasts indefinitely under normal market cycles.

Retirement Income That Keeps Pace With Rising Prices — The Inflation SWP Strategy
Here's the retirement planning trap most Indians fall into: they calculate a fixed monthly withdrawal, confirm the corpus will last 25 years, and feel satisfied. Then inflation hits. That ₹80,000/month withdrawal buys the same lifestyle as ₹35,000/month in 20 years. The corpus lasts on paper — but the lifestyle deteriorates silently.
An Inflation-Adjusted SWP (Systematic Withdrawal Plan) solves this by increasing the monthly withdrawal every year in line with inflation. If you start with ₹80,000/month and inflation is 6%, year 2 withdraws ₹84,800, year 3 withdraws ₹89,888, and so on — maintaining your purchasing power throughout retirement.
The challenge is that higher withdrawals deplete the corpus faster. The solution is a higher starting corpus and a realistic portfolio return assumption. An equity-heavy retirement portfolio might average 10–12% annual returns, providing enough growth margin to sustain increasing withdrawals for 25–30 years.
A common rule for inflation-adjusted withdrawal: your sustainable initial withdrawal rate is approximately 3–3.5% of corpus per year (not 4%, which assumes flat withdrawals). At 3.5% of a ₹3 crore corpus = ₹1.05 lakh/month starting withdrawal that you can increase annually with inflation. This tool shows you exactly how long your corpus survives under your specific withdrawal and inflation assumptions.
