Common Mistakes to Avoid
Critical financial oversights that reduce long-term returns
Ignoring inflation in long-term retirement planning: A ₹50,000/month lifestyle today will require ~₹1.6 Lakhs/month in 20 years at 6% inflation.
Subtracting inflation rate directly instead of Fisher equation: Simple subtraction (12% - 6% = 6%) overstates real returns compared to exact Fisher division (5.66%).
Treating RBI's 4% target as guaranteed: Actual CPI fluctuates based on food, fuel, and global commodity shocks.
